Tray Sealer

Tray Sealer uses totally enclosed vacuum replacement method to conduct food atmospheric fresh-keeping packing, namely in the totally enclosed vacuum chamber, vacuumize the vacuum chamber with vacuum pump to make a high vacuum degree, and then fill the gas for preservation of food. The packing mode can make the residual oxygen content in the container to a minimum, and convenient for precise control of ratio of various fresh-keeping gases. The gas displacement ratio by using the totally enclosed vacuum replacement method may ≥ 99%. It effectively solves the problems of the traditional flush compensation controlled atmosphere packing such as poor fresh-keeping effect, incongruous charged gas ratio, unable to grasp and control the shelf life of fresh food due to the high content of residual oxygen.
