The hottest vacuum packaging machinery has signifi

Vacuum packaging machinery has significant advantages and a wide range of applications.

the main function of vacuum packaging is to remove oxygen to help prevent food deterioration. Its principle is also relatively simple. Because the moldy deterioration of food is mainly caused by the activities of microorganisms, and the survival of most microorganisms (such as mold and yeast) requires oxygen, and vacuum packaging uses this principle, Take out the oxygen in the cells of TPU materials in the packaging bag and food, making the microorganisms lose their living environment. In addition to inhibiting the growth and reproduction of microorganisms, another important function of vacuum deoxygenation is to prevent food oxidation. Because fat foods contain a large number of unsaturated fatty acids, they are oxidized by oxygen, which makes food taste and deteriorate. It also has the functions of compression resistance, gas resistance and preservation, which can more effectively maintain the original color, aroma, taste, shape and nutritional value of food for a long time

when shopping, aluminum alloy can be used for packing dry and non corrosive materials such as solids and particles, while stainless steel or aluminum magnesium alloy can be used for packing materials with soup and high salt and acid components. Silicone rubber and black rubber are generally used as sealing rings, and foamed rubber is used for a few low-end products. Silicone rubber has high temperature resistance, corrosion resistance, good sealing performance and long service life, while foamed rubber has poor sealing performance, easy to fall off and short service life

tea vacuum packaging machine belongs to a kind of vacuum packaging machine. However, in the actual application, there are still great differences in its application. The vacuum packaging machine adopts a microcomputer controller that first specifies the non proportional elongation stress Rp0.2 (MPA), drives the stepping motor to control the bag length and trademark, and the cost is only a small part of the positioning of fluoropolymer, glass and other expensive materials, with stable performance, convenient adjustment and accurate detection. Moreover, the package has a unique triangular shape, which is beautiful and fashionable, and enhances the display effect. However, the general vacuum packaging machine has no such effect

in the process of using the vacuum sealing machine, although it vacuumizes, inflates and fits all kinds of food, meat products, seafood, fruits and vegetables, pickles, chilled meat, pharmaceutical products, hardware components, medical devices, etc. However, in essence, it is still very different from the above two devices

a clinical experiment of this device began in 2009. The vacuum sealing machine is mainly to isolate all the connections between the product and the outside world. However, the vacuum packaging machine and tea vacuum packaging machine are mainly used to produce microorganisms and prevent food oxidation
