Food preservation and packing equipment and method

Abstract

The invention discloses food preservation and packing equipment. The food preservation and packing equipment comprises a sealing machining container and a high-temperature insulation sterilization box; a packing material conveying area, a split charging area, a finished product packing area and a finished product conveying area are arranged in the high-temperature insulation sterilization box; multiple separation plates for forming bent conveying channels are arranged in the packing material conveying area at intervals; an outlet of the sealing machining container and an outlet of the packingmaterial conveying area are connected with inlets of the split charging area and the finished product packing area; and outlets of the split charging area and the finished product packing area are connected with an inlet of the finished product conveying area. Under the condition of not needing any preservative and freezing, the equipment can prolong the food shelf life and guarantee the food quality.

Description

technical field [0001] The invention relates to a food fresh-keeping packaging equipment and method. Background technique [0002] There are two existing non-frozen fresh-keeping methods: 1. adding a large amount of preservatives, 2. first vacuum-packing the processed food and then performing high-temperature cooking and sterilization for a certain period of time. The defects that exist in both existing methods: the first method uses preservatives, and it is well known that preservatives can cause harm to the human body. In the second method, the strength of plastic packaging decreases at high temperatures, and the high temperature causes moisture in the food to precipitate and produce water vapor, which in turn generates high pressure and bursts or damages the sealing port, and loses the sealing effect of the packaging. Therefore, the shelf life is short, and often expires after leaving the factory If there are defective products in the store, the quality of food cannot be...

Defects in both existing methods: the first method uses preservatives, which are known to cause harm to the human body

In the second method, the strength of plastic packaging decreases at high temperatures, and the high temperature causes moisture in the food to precipitate and produce water vapor, which in turn generates high pressure and bursts or damages the sealing port, and loses the sealing effect of the packaging. Therefore, the shelf life is short, and often expires after leaving the factory There are defective products in the store, and the quality of food cannot be guaranteed
