The vacuum packaging machine can automatically extract the air in the packaging bag and complete the sealing process after reaching a predetermined vacuum degree. It can also be filled with nitrogen or other mixed gas, and then the sealing process is completed. Vacuum packaging machine is often used in the food industry, because after vacuum packaging, food can resist oxidation, so as to achieve the purpose of long-term storage.
Stretch film Automatic stretch film vacuum packaging machine is also called full automatic plastic box thermoforming vacuum packaging machine. The principle of the fully automatic stretch film vacuum packaging machine is to use a forming mold, first heat the film, and then use the forming mold to punch the shape of the container, and then fill the package into the formed lower film cavity, and then perform vacuum packaging. It is mainly composed of vacuum system, pumping and sealing system, thermocompression sealing system and electrical control system.
Continuous Continuous vacuum packaging machine is also called rolling vacuum packaging machine, or automatic chain vacuum packaging machine. Its working principle is the use of chain drive, automatic swing cover, continuous output products. The whole machine adopts imported PLC programmable logic controller, computer touch screen operation, fully sealed operating system, the whole machine can be washed with water.
Pull-out The external vacuum packaging machine is a device that puts the package outside the vacuum chamber to complete the vacuum packaging. The external vacuum packaging machine is mainly designed for vacuum packaging of larger packages. Unlike the internal vacuum packaging machine, the external vacuum packaging machine is put into the packaging of the packaged product through the suction nozzle. Inside the bag, evacuate the air, exit the suction nozzle, and complete the sealing.
Cabinet type The whole machine of the vertical cabinet type vacuum packaging machine adopts 304 grade stainless steel material, and the control part adopts the PIC computer version control system. The vertical cabinet vacuum packaging machine is mainly used for vacuum packaging of powder, small particles, liquid or large packaging objects. The vacuum chamber has a large volume and a bag mouth vertical seal. Can be packaged with the product (eg barrels, boxes). Place it directly in the vacuum chamber to complete the vacuum sealing of the inner bag. Open-door operation form is convenient for shelving heavy objects. This machine can be customized according to special size and configuration requirements. Widely used in feed, chemical, food, electronics and other industries.
Bag type Leisure foods such as chicken feet, duck feet, duck neck, dried tofu, small fish, and fish fillets can only be put on the market by vacuum packaging and high-temperature sterilization. The vacuum packaging of this kind of products uses manual charging, and the vacuum chamber is evacuated. Each operation process is intermittent. In each process, it is easy to cause pollution of the finished product or cross infection of people and things. Higher problems and generally tight human resources have restricted the development of the industry and led to the slow development of the small food industry. Bag-type automatic vacuum packaging machine is specially used for continuous and automatic vacuum packaging of snacks such as chicken claws, duck claws, duck necks, dried tofu, small fish, fish blocks and other cooked foods. It can automatically achieve bag removal. , Bagging, coding, supporting bags, drum bags, feeding, metering, filling, vacuuming, sealing, conveying, etc. until the fully automated production of finished products, greatly improving production efficiency.
Vacuum nitrogen Vacuum nitrogen-filled packaging puts the food into the packaging bag, and after the air in the packaging bag reaches a predetermined vacuum degree, it is filled with nitrogen, carbon dioxide, oxygen and other gases, and then the sealing process is completed.
1. Eliminates part of the air (oxygen) in the packaging container, which can effectively prevent food spoilage. 2. The use of packaging materials with excellent barrier properties (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, which can avoid weight loss and taste loss of food, and prevent secondary pollution. 3. The gas inside the vacuum packaging container has been eliminated, which accelerates the conduction of heat, which can improve the efficiency of thermal sterilization and prevent the packaging container from rupturing due to the expansion of the gas during heating and sterilization. In the food industry, vacuum packaging is very common. Vacuum-packed food has a long shelf life, which greatly extends the shelf life of food.
Vacuum packaging machine uses plastic or plastic aluminum foil film as packaging material to vacuum liquid, solid, powdery food, grain, fruit, pickles, preserved fruits, chemicals, medicinal materials, electronic components, precision instruments, rare metals, etc. Packaging, vacuum-packed items can prevent oxidation, mildew, moth-eaten, rot, moisture, and extend the shelf life. It is especially suitable for tea, food, medicine, shops, research institutes and other industries. It has the advantages of beautiful appearance, compact structure, high efficiency, easy operation, seat wheels at the bottom, and easy movement.
