The main function of food vacuum packaging is to remove oxygen, which is helpful to prevent food from spoiling. The principle is also relatively simple. The food spoilage is mainly caused by the activities of microorganisms, and most microorganisms (such as mold and yeast) need oxygen for their survival. And, vacuum packaging is to use this principle to remove the oxygen in the packaging bag and food cells, so that the microorganisms lose their living environment. The following is a description of the performance advantages of food vacuum packaging machines for everyone to understand.
1. The upper working room is made of stainless steel, with high strength, corrosion resistance, large volume and light weight.
2. The heating elements are all installed in the upper working room, which can avoid short circuit and other failures caused by the effects of packaging items (especially liquid), and improve the reliability of the whole machine.
3. The lower work surface is made of stainless steel plane structure, which can not only facilitate the removal of liquid or debris dripping on the work surface during the work, but also prevent corrosion and rust caused by packaging acids, alkalis, salts and other items. The whole machine adopts stainless steel frame structure to ensure the overall quality of the equipment is balanced and greatly improve the service life of the equipment. The upper studio can work in two working positions, which is convenient to operate, high in efficiency, and saves energy.
4. The packaging process is automatically controlled by the electrical system. For different packaging requirements and different packaging materials, there are adjustment knobs for air extraction time, heating time, heating temperature, etc., which are easy to adjust to achieve the packaging effect.
This is why the equipment is developing rapidly in the food industry.
