Continuous air conditioning packaging equipment

Abstract

The invention discloses continuous air conditioning packaging equipment used for air conditioning package of a multi-grid packaging box. The continuous air conditioning packaging equipment comprises a conveyer which continuously moves, wherein the conveyer is composed of a conveyer belt which circulates around a turning roll; and an upper die is arranged above the conveyer belt, the conveyer belt is provided with a plurality of lower die cavity boards which are relatively independent and are used for placing the multi-grid packaging box in a penetrative manner, a lower die base plate is arranged below the conveyer belt and corresponds to the upper die, the lower die base plate is connected with a lower die lifting device which is fixed on the air conditioning packaging equipment, and the lower die base plate does lifting movement in a reciprocating way relative to the conveyer belt when being driven by the lower die lifting device. By adopting the continuous air conditioning packaging equipment disclosed by the invention, air conditioning package can be continuously carried out on the multi-grid packaging box, the closed environment in an air conditioning chamber is good, and air exhaust and aeration are more sufficient, thus the packaging quality is guaranteed, and the refreshing and quality guarantee period of an article in the multi-grid packaging box is prolonged.

Description

technical field [0001] The invention belongs to the field of packaging machinery, in particular to a continuous modified atmosphere packaging equipment for multi-compartment packaging boxes. Background technique [0002] At present, in the fast food industry, in order to prevent the mixed flavor of rice, vegetables and soup, a multi-compartment lunch box has been developed, which can separate the meals and then directly seal them with plastic wrap, but this can not achieve the purpose of long-term freshness preservation. [0003] Modified atmosphere packaging is a packaging method that replaces the air in the packaging container with a protective gas suitable for food preservation to inhibit bacterial reproduction and achieve long-term preservation and freshness. The packaging principle of modified atmosphere packaging is to use modified atmosphere fresh-keeping gas (2 to 4 kinds of gases are mixed according to the ratio of food characteristics) to replace the air in the pac...

AI Technical Summary

Problems solved by technology

This packaging equipment can carry out modified atmosphere packaging for single-compartment lunch boxes, but for the modified atmosphere packaging of multi-compartment lunch boxes, this kind of equipment has incomplete gas replacement in the lunch boxes, resulting in inconsistent air pressure in each separated space, and the middle partition Problems such as poor heat sealing effect on
