The actual effect of anti-corrosion and fresh-keeping of vacuum fresh-keeping equipment

Fresh fingerlings can choose a mixture of O2, nitrogen and carbon dioxide to achieve the actual effect of anti-corrosion and fresh-keeping. For fried peanuts and other commodities, after the vacuum packaging is carried out, nitrogen filling can further reduce the residual oxygen content in the packaging, that is, nitrogen filling packaging, which achieves better practical results than vacuum preservation. The outer packaging of fresh vegetables and fruits can use a mixture of hypoxia, high carbon dioxide and nitrogen gas, which can inhibit the metabolism of vegetables and fruits, thereby maintaining the freshness of vegetables and fruits from being destroyed.

Food characteristics of vacuum fresh-keeping equipment

Modified atmosphere packaging is an up-to-date method of food packaging materials. It is suitable for cooked vegetables, frozen food, poultry and other meat products that are not easy to keep fresh. Put the ingredients in the packaging box, and replace the natural gas in the packaging box according to a certain percentage of fresh-keeping gas. Selection, excellent sealing processing technology, in the freezing ambient temperature, increases the shelf life and freshness.

The food characteristics of the fully automatic packaging machine with modified atmosphere locking. As we all know, each type of food has its own characteristics, and different foods have different stirring ratios for the freshness-locking gas. In fact, it is necessary to choose the appropriate freshness-locking agent according to the characteristics of the food itself. vapor. Fresh meat products can use a mixed gas composed of high oxygen content and carbon dioxide, which can keep the color of fresh meat products unchanged, and also achieve the actual effect of anti-corrosion. Cooked meat products (cooked meat, fried fish, etc.) can use a mixed gas composed of carbon dioxide and nitrogen, which can achieve the actual effect of anti-corrosion.

Vacuum fresh-keeping equipment sealing machine does not heat up: the heating strip is burned out and the heating strip is replaced; the heating time controller is burned out (the two lights are on at the same time when starting, and the OMRON light is light yellow), replace the time controller; the heating wire is burned out and replace the hot wire, and install it firmly; control the poor contact of the heating temperature band switch, repair or replace it; control the heating DC contactor to repair or replace it without calibration (use a cyclone to blow away the dirt) or replace; the heating transformer is broken and replaced.
