Refrigerated transport method for quick-frozen food

Abstract

The invention provides a refrigerated transport method for quick-frozen food. A refrigerated transport device for the quick-frozen food is adopted in the refrigerated transport method. The refrigerated transport device for the quick-frozen food comprises a base, a mounting plate, a vacuum air extractor, an air extraction pipe, a locking mechanism, a heat sealing mechanism, a roller column and a motor. According the refrigerated transport method for the quick-frozen food, the opening of a quick-frozen food packaging bag and the joint of the quick-frozen food packaging bag and the air extraction pipe can be sealed through the locking mechanism, so that the situations that due to the fact that the sealing effect of the air extraction pipe and the quick-frozen food packaging bag is poor, air extraction is not thorough when the vacuum air extractor extracts air from the quick-frozen food packaging bag and the shelf life of the food in the quick-frozen food packaging bag is influenced are prevented; in addition, due to the design of the heat sealing mechanism, the quick-frozen food packaging bag close to the sealing opening can be subjected to slitting treatment while the quick-frozen food packaging bag is subjected to heat sealing, so that the working efficiency of the refrigerated transport device for the quick-frozen food is improved.

Description

technical field [0001] The invention relates to the technical field of quick-frozen food packaging, in particular to a method for refrigerating and transporting quick-frozen food. Background technique [0002] Quick-frozen food is a quick-frozen food processed at a rapid low temperature. The moisture and juice in the food tissue will not be lost, and at such a low temperature, microorganisms will basically not multiply, and food safety is guaranteed. In order to facilitate the transportation of quick-frozen foods, the quick-frozen foods are generally pre-packaged in quick-frozen food packaging bags. [0003] In the process of packaging quick-frozen food in the prior art, the quick-frozen food packaging bag is generally vacuum-evacuated by a vacuum pumping device, and then the quick-frozen food packaging bag is heat-sealed by a heat-sealing machine. During the vacuum extraction process, the extraction pipe is generally put into the inside of the quick-frozen food packaging b...

Problems solved by technology

[0003] In the prior art, during the packaging process of quick-frozen food, the quick-frozen food packaging bag is generally vacuum-pumped by vacuum pumping equipment, and then the quick-frozen food packaging bag is heat-sealed by a heat-sealing machine. During the vacuum pumping process, the suction pipe is usually put into the quick-frozen food packaging bag from the opening of the quick-frozen food packaging bag, so there is often a gap between the suction pipe and the quick-frozen food packaging bag, and the sealing effect is poor. As a result, the vacuum pump does not exhaust the quick-frozen food packaging bag completely, which affects the shelf life of the food in the quick-frozen food packaging bag; The packaging bag is cut to keep the seal flat. The heat sealing equipment in the prior art has a simple structure, and it is impossible to cut the quick-frozen food packaging bag near the seal while heat-sealing the quick-frozen food packaging bag. processing, resulting in inefficiency in the vacuum packaging of quick-frozen food packaging bags
