Aluminum foil sealing machine, as a conventional packaging equipment, has been widely used in multiple industries such as food, medicine, cosmetics, etc. It uses the principle of electromagnetic induction to fuse the aluminum foil sheet with the bottle mouth, thereby achieving product sealing and preservation. 01 - Working principle When the aluminum foil sealing machine is working, the AC power supply is converted into DC power through a rectifier, and then supplied to a high-frequency oscillator to generate high-frequency current. When this high-frequency current passes through the high-frequency coil, a strong magnetic field is generated around it. When the aluminum foil passes through the induction zone of the sealing machine, a strong magnetic field will penetrate the aluminum foil and generate strong eddy currents within it. Due to the inherent resistance of aluminum foil, these eddy currents can quickly generate a large amount of heat inside the foil, causing it to melt locally. At the same time, the pressure device of the sealing machine will apply a certain amount of pressure to the aluminum foil sheet, making it tightly adhere to the mouth of the container. As the aluminum foil melts, it will tightly bond with the container mouth under pressure, forming a complete and sealed seal. Throughout the entire process, the sealing machine precisely controls parameters such as heating time, pressure, and temperature through a control system to ensure the quality and stability of the sealing. At the same time, the sealing machine is also equipped with safety protection devices, such as overheating protection, overload protection, etc., to ensure the safety and reliability of operation.

Summer is here, how can you protect your skin? No doubt people use sunscreen spray more. The sunscreen spray is popular among users because of its convenient use and good experience effect. So, do you know how sunscreen spray is produced? Here are the secrets of sunscreen spray production process and required equipment. Sunscreen spray is an aerosol product, which means that lotion or suspension is sealed in a pressure resistant container with a special valve system together with a suitable propellant, and the contents are sprayed out as mist with the pressure of the propellant. There are two packaging forms of sunscreen spray, one is on valve kind and two is bag on valve kind. On valve kind The propellant and material body of the on valve kind packaging sunscreen spray are mixed in the aerosol can. The propellant is used to pressurize to push the material body to spray out and assist in the material body atomization. It is sprayed together with the material body. If propane butane is seen in the composition list of the general sunscreen spray, it is the unitary sunscreen aerosol. Propane butane is flammable gas, so it is not very safe and environmentally friendly. Bag on valve kind The bag on valve kind packaging sunscreen spray also has a container in the aerosol can (usually prone to volume change under pressure), which forms two separation spaces wi

From the perspective of quantitative principles, powder packaging machines mainly have two methods: volumetric and weighing. (1) Volumetric formula Volume based quantitative filling is achieved by controlling the volume of the filled material. The screw based quantitative filling machine belongs to the category of volume based quantitative filling. Its advantages are simple structure, no need for weighing devices, low cost, and high filling efficiency. The disadvantage of screw type quantitative filling machine is that the filling accuracy varies greatly depending on the different materials being filled, mainly relying on the stability of the apparent density of the filled materials, the uniformity of material particle size, as well as the moisture absorption and looseness of the materials. Therefore, volumetric filling is mainly suitable for material particles with uniform particle size, stable bulk density, and good self flow properties. Volume based quantitative filling packaging can be divided into two forms according to the different measurement methods of materials. One method is to control the flow rate or time of the filled material to control the filling volume, for example, by controlling the number or time of rotation of the screw in the screw filling machine to control the volume of the filled material, and by controlling the vibration time of the vibrating feeder to control the volume of the material. Another form is to use the same measuring container to measure materials for quantitative filling, such as using a measuring cylinder, measuring cup, or plunger type quantitative filling machine. Regardless of which volumetric quantitative filling method is used, there is a common problem, which is to ensure the stability of the bulk density of the filled

Palletizer have many advantages, such as improving production efficiency, reducing labor costs, and improving product quality. However, it also has some drawbacks and limitations, as follows: 1. High maintenance costs: The Palletizer is a complex mechanical equipment that requires regular maintenance and upkeep, including replacing parts, adjusting parameters, etc., which will increase the maintenance costs of the enterprise. 2. Limited adaptability: The Palletizer has limited adaptability to different types, sizes, and shapes of goods and packaging methods, and may require additional use or adjustment for some special goods or packaging methods. 3. High initial investment cost: The Palletizer is a high-tech equipment with relatively high purchase and maintenance costs, requiring enterprises to have certain financial strength and investment willingness. 4. High requirements for users: Although Palletizers can replace some manual labor, they still need to be supervised and adjusted by the users, requiring high skills and qualities from the users. 5. High failure rate: Due to the high complexity of the mechanical and electronic components of the Palletizer, which is a highly automated equipment, there may be some malfunctions or abnormal situations that require timely maintenance and handling by the enterprise.

Many people wonder how the labels on these bottles and cans are put on? In fact, the labeling machine is the middle stage of beverage manufacturing, used to label the filled beverage, add beverage logo instructions, and enhance promotional value. It involves industries such as food, pharmaceuticals, daily chemicals, agrochemicals, coatings, etc., and has a certain market size. According to the different shapes and specifications of the bottle body, there are usually two types of equipment in the filling label process: a labeling machine and a labeling machine. The labeling machine is used to insert the closed plastic label into the bottle body from top to bottom, while the labeling machine wraps the label around the bottle body and relies on self-adhesive and hot melt adhesive to adhere to the bottom paper. The equipment consists of a bottle delivery assembly line and two sets of delivery marking lines. The bottles flow in, are equidistant and pulled apart by the bottle separation mechanism, and then alternately inserted into the labels by two sets. Finally, they enter the high-temperature device for heat shrinkage and fixation. 01 Bottle delivery assembly line Bring the bottle, pull the screw apart at equal intervals to ensure the rhythm of bottle feeding, alternate odd and even labeling at both ends, heat shrink at high temperature, and flow out the finished product 02 Lab

There are many types of filling machines commonly used in the industry, such as liquid type, paste type, and powder type. Their working principles are almost identical. However, some thicker filling machines require high pressure to fill the product into the bottle. The working principle of the filling machine is actually to achieve a linkage effect, which requires the use of transmission machinery to drive, so that various parts can work in coordination with each other. The commonly used semi-automatic filling machines with low production efficiency include direct current liquid filling and piston type paste filling. The working principle of direct current liquid filling is relatively simple. The filling method of constant current timing precisely controls the filling amount by adjusting the filling time under certain liquid level pressure conditions. A semi-automatic piston filling machine is a filling machine that fills high concentration fluids. It uses a three-way principle of a piston and a rotary valve driven by a cylinder to extract and dispense high concentration materials. The stroke of the cylinder is controlled by a magnetic spring switch to adjust the filling amount. The higher production efficiency naturally comes from various filling production lines equipped with different filling machines. The advantage of this type of filling machine production line lies in providing the manufacturing industry with high-performance, stable and reliable filling production lines; Less material waste, cost savings in large-scale production: programming and control according to production processes, high production efficiency, and low environmental pollution during the production process. Due to its special working principle, the filling machine production line can realize the route formed by a series of production activities such as processi

A fruit juice sterilizer is a device that can sterilize fruit juice, effectively removing bacteria and viruses from the juice and ensuring its hygiene and safety. There are currently various types of fruit juice sterilizers on the market. Let's introduce them below. 1. Tubular sterilizer Widely used for sterilization of low viscosity materials such as fruit juice, milk, granular fruit juice, soy sauce, soup, etc. In order to extend the shelf life of materials after sterilization and cooling of equipment, single stage, double stage, or multi-level combination systems can be used according to the sterilization, insulation, and cooling technical requirements of the materials. 2. Cannula sterilization machine Place the product into the heat exchanger unit from the storage tank where the sterilizer has been installed, heat the product with hot water until it reaches the sterilization temperature, then maintain the product at the sterilization temperature, and then cool it to the filling temperature with cooling water or chilled water, especially suitable for sterilization of high viscosity materials such as jam and concentrated fruit juice. The sterilizer has a 4-layer tubular structure, with the inner and outer layers passing through hot water, and the middle layer running together with the product. The heat exchange area is large, the energy consumption is low, and it is easy to maintain. Mirror welding technology is used to keep the

■ 6 ■ Different raw material costs Hot filling: The bottle body and mouth are required to be able to withstand high temperatures (low heat shrinkage rate), so high quality requirements are placed on the bottle and lid; Sterile cold filling: There is no high temperature resistance requirement for bottles and lids, so lightweight bottles and individual lids can be used. Compared to hot filling, the packaging cost of sterile cold filling is lower. ■ 7 ■ Different operating costs Hot filling: During the production process, the consumption of disinfectant is relatively low, but the production line speed is slow, and the production capacity is relatively low. Sterile cold filling: The consumption of disinfectant in production is relatively high, but the production speed is fast, and the production capacity is high. In comparison, the operating cost of sterile cold filling is lower than that of hot filling. ■ 8 ■ Outstanding advantages of PET sterile cold filling compared to hot filling. Adopting ultra-high temperature instantaneous sterilization technology (UHT), the heat treatment time of the material does not exceed 30 seconds, ensuring the taste and color of the product to the greatest extent possible, and preserving the content of vitamins (thermosensitive nutrients) in the material to the greatest extent possible.

Sterile cold filling refers to the cold (room temperature) filling of beverage products under sterile conditions, which is different from the commonly used high-temperature hot filling method under normal conditions. When filling under sterile conditions, the parts on the equipment that may cause microbial contamination of the beverage are kept in a sterile state, so there is no need to add preservatives to the beverage, and there is no need to perform post sterilization after the beverage is filled and sealed. This can meet the requirements of a long shelf life and maintain the taste, color, and flavor of the beverage. ■ 1 ■ Different filling processes Hot filling: The product, bottle, and lid are sterilized. After the product is filled into a PET bottle, the center temperature of the product is measured to be 88 degrees. High temperature products are sterilized by pouring the bottle and then cooled to room temperature in a cooling machine; Cold filling: Sterilize the product, bottle, and lid separately, fill them in a sterile environment, and completely seal the product and bottle before leaving the sterile environment. ■ 2 ■ Differences in process flow The biggest difference is the heating time of the product. Aseptic cold filling: The product uses UHT ultra-high temperature instant sterilization, then quickly cools to room temperature, and is stored in a sterile tank for filling at any time; Hot filling: The product adopts UHT high-temperature instantaneous sterilization, and then cools to above 90 degrees; After infusion, the product temperature is 88 degrees. Due to the prolonged heating time of the product, it has a certain impact on color, flavor, nutrition, etc.

Beverage filling machines are a subclass of packaging machinery used for producing bottled, barreled mineral water, and other drinking water. It consists of cleaning, filling, and sealing. It is an ideal equipment for producing mineral water and purified water. Next, let's take a look at the three commonly used canning methods: 1. Atmospheric pressure method The normal pressure method, also known as the pure gravity method, means that under normal pressure, liquid materials flow into packaging containers by their own weight. Most free flowing liquid materials without gas can be filled in this way, such as Baijiu, fruit wine, milk, soy sauce, vinegar, etc. 2. Isobaric method The isobaric method, also known as the pressure gravity filling method, is to first inflate the packaging container under high atmospheric pressure, so that the air pressure is equal to the air pressure inside the storage tank, and then rely on the weight of the filling liquid flowing into the packaging container. This method is commonly used for filling carbonated beverages, such as beer. This method can reduce the loss of CO2 contained in this type of product and prevent excessive bubbles from affecting product quality and quantitative accuracy during the filling process. 3. Vacuum method The vacuum method is used for filling under conditions below atmospheric pressure and can be carried out in two ways: ① Differential pressure vacuum The storage tank is in a normal pressure state, only vacuuming the packaging container to form a vacuum, and filling is completed by relying on the

The liquid filling machine is mainly composed of a translational filling part, a piston filling part, a material handling conveyor line, and a liquid storage tank. 1) Tracking filling part: The main function is to synchronously translate and follow the bottle filling liquid with the can mechanism. 2) The piston filling part is mainly responsible for extracting the liquid from the liquid storage tank and driving the liquid into the filling head through the pipeline according to the multi-stage speed control. 3) Material handling conveyor line: mainly responsible for conveying empty bottles and playing the role of controlling the spindle. 4) Liquid storage tank: Control the storage of tank liquid based on liquid level sensors. Tracking filling machine: Empty bottles are transferred to the filling machine conveyor shaft along the material handling conveyor line, and the position of each bottle is obtained through photoelectric sensors (probes). The bottles enter the filling machine, and each can is filled with liquid in sequence, automatically following intelligent selection to meet the requirements of no bottle leakage or refilling. The conveyor belt does not stop, greatly increa

With the development of science and technology and the continuous changes in consumer market demand, people have begun to put forward higher requirements for packaging equipment. The stronger the functionality, the better, and the simpler the operability, the better. Driven by strong market demand, both inner and outer packaging can now be carried out manually or mechanically. Among them, the outer packaging generally involves equipment such as labeling machines, inkjet printers, packing machines, and bundling machines. In daily life, packaging on consumer goods usually appears in the form of labels, which are applied in various industries, such as shampoo, medicine bottles, sauce bottles, and beverages; And in most cases, the labels on these products are automatically labeled by self-adhesive labeling machines. The self-adhesive label paper used by the Hanmo labeling machine is a roll type. During the operation of the machine, the bottle sorting machine's supporting system automatically enters the bottle, and the roller tears the label off the backing paper and attaches it to the required labeling position of the target product. It is an automated packaging engineering equipment. The labels affixed by the labeling machine are neat and beautiful. With the development of labeling technology, its functions have become more complete, and efficiency and accuracy have steadily improved, providing a good foundation for the large-scale production of production enterprises.

Installation precautions 1. After unpacking the machine, first check if the random technical information is complete and if the machine is damaged during transportation, in order to solve the problem in a timely manner. 2. Install and adjust the feed and discharge components according to the external diagram in this manual. 3. Add new lubricating oil to each lubrication point. 4. Rotate the machine with a joystick to check if the machine is running in the correct direction (counterclockwise facing the motor spindle), and the machine must be grounded for protection. Usage, Maintenance, and Installation 1. When adjusting the machine, tools should be used appropriately. It is strictly prohibited to use too large tools or force too hard to disassemble parts to avoid damaging the machine or affecting its performance. 2.

Therefore, it is necessary to: (1)Before shift handover, each part of the machine surface should be cleaned once and clean lubricating oil should be added to each workstation. (2)It should be thoroughly cleaned once a week, especially in areas that are difficult to clean during normal use, or blown clean with compressed air.

Scientific research has shown that there are many factors that can cause food spoilage, but the two main culprits are the microorganisms hidden in the food and the ubiquitous oxygen in the environment. Microorganisms grow and reproduce in food, consuming the nutrients in the food, producing various chemicals and even toxins, causing food spoilage and spoilage. Oxygen will react with many nutrients in food, such as fats, vitamins, pigments, etc., causing damage to these nutrients. The principle of vacuum packaging for food preservation is to minimize the oxygen content in the packaging container as much as possible, so that most microorganisms, especially aerobic microorganisms, stop reproducing or even die in a state of hypoxia. The oxidation reaction of nutritional components in food is also suppressed due to the lack of oxygen, thereby effectively maintaining the color, aroma, taste, and nutritional value of the food, and extending its warranty period. Vacuum packaging technology is a type of food preservation technology that originated in the 1940s. Since the successful application of polyester and polyethylene plastic films in food packaging in 1950, vacuum packaging technology has developed rapidly, gradually extending from bagged products to bottled and canned products. As a result, vacuum capping machines have emerged, widely used in the production

Factors affecting the price of fully automatic filling machines 1. Equipment specifications: Equipment specifications are an important factor affecting the price of fully automatic filling machines. Generally speaking, the larger the equipment specification, the higher its price. For example, the production capacity, number of bottling ports, and filling methods (negative pressure filling, positive pressure filling, weight filling) of a filling machine will all affect its price. 2. Production capacity: Production capacity is another important factor in the price of fully automatic filling machines. Generally speaking, the larger the production capacity, the higher its price. Production capacity refers to the volume or quantity of materials that the equipment can handle per hour. Different products have different requirements for production capacity, such as juice and beverage products, and high-speed fully automatic filling machines are more suitable; Products with higher viscosity require corresponding filling equipment. 3. Brand: The brand of the fully automatic filling machine is also

❸Filling material The most commonly used filling machine for sauce products such as chili sauce, mushroom sauce, and beef sauce is the piston type filling machine. The principle of a piston filling machine is to extract materials into the cylinder barrel through a piston and then press them into the packaging bottle. The selection of a filling machine first depends on the production capacity planning. For example, if there are over a thousand bottles per hour, selecting a single head sauce filling machine can meet the requirements. If you require filling 5000 or 6000 bottles per hour, you need to choose a model with ten or twelve heads. Additionally, select the machine structure based on the material characteristics. Common sauces, such as garlic chili sauce and tomato sauce, have good fluidity and do not contain hard particles. They are filled using a vertical structure sauce filling machine. If you need to fill sauces such as mushroom sauce, chopped peppers, beef sauce, and oil spiced chili, which contain particles and are easy to separate liquid components, the filling machine needs to adopt a horizontal structure. The main difference between a horizontal structure and a vertical structure is whether the cylinder is horizontal or vertical. The horizontal structure requires a larger frame because the cylinder barrel needs to be placed horizontally. Therefore, the cost of a horizontal sauce filling machine is generally higher than that of a vertical filling machine. Another indicator that needs to be paid attention to is the filling accuracy. Generally, for 200g of sauce, the upper and lower deviations need to be controlled within 6g. The filling accuracy of sauce is mainly related to

The most common packaging methods for seasoning sauces are wide mouth glass bottles and tin caps. The main packaging process includes empty bottle cleaning, empty bottle sterilization, material filling, sealing and capping, whole bottle sterilization, labeling and coding, packaging and warehousing, etc. ❶Empty bottle cleaning The main purpose of empty bottle cleaning is to remove impurities such as dust and glass shavings that may remain inside the bottle. Commonly seen are air blown and water washed bottles. Washing a bottle with water is achieved by spraying a cleaning solution into the bottle to remove impurities. This cleaning method is suitable for materials containing water (the material will not deteriorate when soaked in water). If water washing is used and the material is prone to deterioration in contact with water, it needs to be dried after washing. Empty bottle dryers generally use thermal energy for drying, which consumes relatively high energy. Air blowing is the process of removing solid impurities from the inside of a bottle by injecting clean high-pressure air into the bottle. This bottle cleaning method does not require drying the bottles, but requires high-temperature sterilization or ultraviolet sterilization. In addition, it is necessary to consider the compatibility of the bottle washing machine with the bottle type. Generally, various bottle types are used for sauce products. The bottle clamping mechanism of the bottle washing machine is designed reasonably and compatible with multiple bottle types, making it particula

Automatic weighing and filling machine is a modern mechanical equipment that can automatically complete the weighing and filling of materials on the production line. The emergence of this type of equipment has greatly improved production efficiency and quality, reduced labor costs, and become an indispensable part of modern production lines. Principle Automatic weighing and filling machines are usually composed of weighing systems, filling systems, conveying systems, and other components. Its working principle is: firstly, the material enters the weighing system through the conveying system, and the weighing sensor weighs the material and determines the filling amount; Then, the filling system fills based on the data transmitted by the weighing sensor; Finally, the filled material is transported by the conveying system to the next process. The entire process does not require manual intervention and is fully automated. Application scope Automatic weighing and filling machines are widely used in various industries such as food, medicine, and chemical industry. In the food industry, it can be used for filling various sauces, seasonings, snacks and other products; In the pharmaceutical industry, it can be used for filling various drugs and medical devices; In the chemical industry, it can be used for filling various chemical raw materials, paints, coatings, and other products. Advantage Compared to traditional manual filling methods, automatic weighing filling machines have the following advantages: Improving production efficiency: The automatic weighing and filling machine can achieve automate

Aerosol is a type of aerosol product produced in the modern fine chemical industry. Its production and filling require the use of professional aerosol filling machines, which have the advantages of small volume, convenient carrying, simple use, fine sprayed materials, uniform distribution, and full application effect. The aerosol cans are made of aluminum and Tinning. The BOV packaging and filling machine is a special equipment designed specifically for bag on valve aerosol products. It consists of a sealing inflation system and a forced filling system, which fills the aerosol can with compressed air, seals the valve with a bag, and fills the bag with raw materials to completely separate the raw materials from the tank. The use of compressed air instead of propane liquefied gas and dimethyl ether as propellants has solved the problem of corrosion and leakage of aerosol can raw materials. When the valve opens, the compressed air of the aerosol can compresses the bag, pressing the raw material out of the aerosol can. After the raw materials are completely extruded, the compressed air of the aerosol can still remain in the aerosol can and can be repeatedly filled. Spray bottle is not in the form of aerosol cans, but in the form of micro spray, so it does not need the aerosol filling machine to fill the propellant gas. In recent years,

Disc filling machine Disc filling machines are often used to fill large amounts of food. The disc filling machine has a rotating turntable, and the periphery of the turntable is the filling point. This ensures that there is sufficient time to control the filling process and the container can flow continuously. The disc filling machine can be used for non carbonated media such as mineral water, fruit juice, or dairy products. It usually uses a two-stage filling method. After quickly filling the container, slowly fill it and use a reduced flow rate to reach the desired capacity. This control can be achieved by connecting a bypass valve upstream of the filling valve and a filling valve with a servo or two-stage actuator. In addition, oxygen sensitive products require the use of nitrogen to replace the remaining oxygen before closing the container. For carbonated media, additional auxiliary valves are required to regulate the container to be filled and ensure the supply of carbon dioxide. Linear filling machine Linear filling machines are usually used to fill cosmetics, drugs, cleaning agents, oils and fats, as well as some small doses of beverages. Linear filling

Aerosol refers to the preparation containing drugs, lotion or suspensions and suitable projectiles, which are jointly sealed in a pressure resistant container with a special Valve system. When used, the contents are sprayed as mist with the help of the pressure of the projectiles, and used for lung inhalation or directly sprayed to the mucous membrane of the cavity, skin and space for disinfection. It is widely used in medicine and daily chemical industry, especially in the daily chemical industry, such as sunscreen spray, moisturizing spray, toner spray and other products emerge in endlessly. Aerosol is a pressure packaging product, with most of its functional ingredients being organic solvents and most of its propellants being flammable gases. Therefore, Aerosol products are also flammable and explosive dangerous goods, and the mixing of raw materials with propellants can cause secondary pollution of the raw materials; When the ambient temperature increases, the pressure inside the Aerosol will also sharply increase, exceeding the temperature limit may cause an explosion due to excessive pressure. Therefore, improving the purity of raw materials, improving the safety performance of Aerosol, and ensuring stable pressure inside the tank are all crucial. Therefore, the valve of Aerosol was improved and a binary spray bag valve was developed. Bag-On-Valve includes a valve seat, a hollow valve body, a valve stem, an inner sealing ring, a spring, and a sealing bag. The valve body is fixedly arranged inside the valve seat, and the valve stem runs through the valve body. The inner sealing ring is pressed between the top of the valve body and the inner wall of the valve seat, and the inner sealing ring is sleeved at one end of
