Pulse sterilization continuous box type modified atmosphere packaging machine

Abstract

The invention discloses a pulse sterilization continuous box type modified atmosphere packaging machine. The modified atmosphere packaging machine comprises a transmission system, a packaging system and a film sealing system and further comprises a control system, wherein the transmission system, the packaging system and the film sealing system are installed on a rack, a sterilization system is installed at the front end of the transmission system, and the packaging system comprises a film sealing device, a gas replacement device, a hot-sealing device and a cutting device. With the method, the modified atmosphere packaging machine is simple in structure, capable of performing continuous sterilization and continuous and automatic modified atmosphere packaging on products through a small number of work stations, high in packaging speed and capable of achieving the high gas replacement rate and the high gas mixing accuracy.

Description

technical field [0001] The invention relates to the field of modified atmosphere packaging machines, in particular to a pulse sterilization continuous box type modified atmosphere packaging machine. Background technique [0002] Consumers' requirements for food are generally safe to eat, stable in nature, and without additives. In traditional food processing, heat sterilization is mainly used, which leads to the destruction of nutrients, increased discoloration, and loss of volatile components. Cold sterilization (physical sterilization) is a new type of contemporary technology. The physical sterilization conditions are easy to control, and the external environment has little influence. Since the temperature of the food does not rise or rises very low during the sterilization process, it is beneficial to maintain the functional components of the food. It is also beneficial to maintain the color, aroma, taste and nutrients, so it is very necessary to adopt cold sterilization...

AI Technical Summary

Problems solved by technology

[0003] However, the fresh-keeping packaging in the existing food and other fields has gradually developed from vacuum packaging to modified atmosphere packaging, that is, other inert gases are used to replace the air in the food packaging box. Modified atmosphere packaging has many advantages that traditional vacuum packaging cannot match. It is faster and has higher productivity, but the current modified atmosphere packaging machine also has some areas that need to be improved. For example, the simple modified atmosphere packaging machine can only work in a single step, and the packaging efficiency is low; the structure of the modified atmosphere packaging machine that can operate continuously and automatically is relatively complicated. Ventilation, box sealing, film cutting and other operations generally require several stations to complete, the equipment work line is long, and the required work space is large
