Principle of fast vacuum packaging machine:
A fast vacuum packaging machine can automatically extract the air in the packaging bag, and complete the sealing process after reaching the predetermined vacuum degree. It can also be filled with nitrogen or other mixed gases, and then complete the sealing process. Vacuum packaging machines are often used in the food industry, because after vacuum packaging, food can resist oxidation, so as to achieve the purpose of long-term storage.
The main function of vacuum packaging is to remove oxygen to help prevent food from spoiling. The principle is also relatively simple. The mold and spoilage of food are mainly caused by the activities of microorganisms, and most microorganisms (such as molds and yeasts) need oxygen to survive. Yes, and vacuum packaging uses this principle to extract oxygen in the packaging bag and food cells, so that microorganisms lose their living environment. Experiments have proved that when the oxygen concentration in the packaging bag is ≤1%, the growth and reproduction speed of microorganisms will drop sharply. When the oxygen concentration is ≤0.5%, most microorganisms will be inhibited and stop reproducing. (Note: Vacuum packaging cannot inhibit the growth of anaerobic bacteria and the deterioration and discoloration of food caused by enzyme reactions, so it needs to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt Marinated etc.)
Features of fast vacuum packaging machine:
1. Part of the air (oxygen) in the packaging container is eliminated, which can effectively prevent food from spoiling.
2. The use of packaging materials with excellent barrier properties (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of package contents, which can prevent food weight loss and taste loss, and prevent secondary pollution.
3. The gas inside the vacuum packaging container has been eliminated, accelerating the heat transfer, which can improve the efficiency of heat sterilization and avoid the packaging container from rupturing due to gas expansion during heat sterilization.
In the food industry, vacuum packaging is very common, various cooked products such as chicken legs, ham, sausages, grilled fish fillets, beef jerky, etc.; preserved products such as various pickles, soy products, preserved fruits and other foods that need to be kept fresh Increasingly, vacuum packaging is used. Vacuum-packaged food has a long shelf life, which greatly extends the shelf life of the food.
1. Feeding and discharging method: forward and right out.
2. The compression vacuum packaging machine adopts a hot box fixed instant heating method to save energy.
3. Special electric heating arrangement, even heat distribution.
4. The body is small and the floor space is small.
5. Suitable for small batch production and medium-volume production. Vacuum packaging machines that can cooperate with assembly line operations to improve efficiency.
6. Using original imported spare parts from Taiwan, Japan and South Korea, the performance is stable and reliable.
Structure of fast vacuum packaging machine:
If you want to understand the vacuum packaging machine, you have to know what structure the vacuum packaging machine is composed of. Many of our customers use vacuum packaging machines. Vacuum packaging machines use vacuum pumps to vacuum the products in the bags and seal them. With such a simple description, many customers are still not very clear about the principle and structure of the vacuum packaging machine. They always feel that this equipment is very simple and not technically competent.
Vacuum packaging machines, including food vacuum packaging machines, are composed of a vacuum system, a gas-pumping and sealing system, a heat-pressing sealing system, and an electrical control system. The intelligent packaging all-in-one machine will automatically seal the packaging bag immediately after it is vacuumed into a low vacuum. Due to the high vacuum in the bag, there is very little residual air, which inhibits the reproduction of bacteria and other microorganisms, avoids oxidation, mildew and corruption, and at the same time Some soft items, after being packaged by a fully automatic vacuum packaging machine, can reduce the packaging volume and facilitate transportation and storage. The principle of the desktop vacuum packaging machine is based on plastic composite film or plastic aluminum foil composite film as the packaging material. It is suitable for solid, liquid, powder, and paste food, grain, fruit, pickles, preserved fruits, chemicals, electronic components, precision instruments, Rare metals, etc. are vacuum packed or vacuum-filled.
