Intelligent unfreezing warehouse for frozen meat

Abstract

The invention relates to an intelligent unfreezing warehouse for frozen meat. The intelligent unfreezing warehouse for the frozen meat consists of an electrical system, an air circulation system, a humidity control system, a temperature control system, a temperature and humidity data acquiring system and a microcomputer intelligent control system. Low-pressure cleaning steam serves as a working medium, and an unfreezing procedure runs automatically to unfreeze the frozen meat of which the storage temperature is minus 18 DEG C into the frozen meat of which the temperature is minus 1 DEG C to 1 DEG C. The temperature rising speed of raw meat and the temperature gradient from the surface to the center of the meat are controlled, so that frozen ice of the inside and the outside of cells of the raw meat is melted slowly, unfreezing liquid loss is avoided, the flavor and the taste of the meat are kept, reproduction of surface microorganisms and bacterial colonies of the raw meat is restrained, and safety of the raw meat in an unfreezing process is guaranteed.

Description

technical field [0001] The invention relates to an intelligent thawing storehouse, which is suitable for intelligent thawing of frozen meat. Background technique [0002] my country is a major meat producer in the world. In 2014, the total output of livestock and poultry meat was 85.4 million tons, more than half of which were stored in frozen storage. Frozen storage can significantly extend the shelf life of livestock and poultry meat. Frozen meat is also an important area for the import and export of meat products. The main product form of inter-circulation. Frozen meat thawing is the primary process of meat consumption and meat processing, which directly affects the sensory quality and processing quality of meat. Therefore, thawing of frozen meat is very important in meat processing. [0003] At present, the thawing methods commonly used by domestic livestock and poultry slaughtering and processing enterprises include natural thawing and water thawing. Air natural thawin...

Problems solved by technology

The water thawing method generally builds a thawing pool in the existing space. The pool is filled with circulating or stagnant water. The speed is faster than the air thawing method, but it is easy to cause the loss of nutrients and make the flesh pale. The thawing pool occupies a large area and the number of thawing is limited.
