Small river crab belly meat dry-freezing and suction method

Abstract

The invention discloses a small river crab belly meat dry-freezing and suction method, which comprises the following steps of: 1) raw material treatment: selecting small river crabs with weight being less than 80g and conducting raw material acceptance inspection such as sensory and visual inspection; 2) pretreatment: decomposing the crabs and separating crab legs from crab belly meat; and decomposing the crab belly meat and splitting the side surface of the crab belly meat into two parts; 3) air-drying; 4) treatment in a cold storage house: adding a quick freezing dryer in the cold storage house, controlling the temperature of the cold storage house to be approximate 35 DEG C below zero and putting the crab belly meat in the cold storage house for quick freezing; 5) dry-freezing: putting the crab belly meat in the cold storage house for dry-freezing for 3 hours, wherein the volume of the dry-frozen crab belly meat is one-fifth smaller than the volume of the crab belly meat before dry-freezing and crab shells are basically separated from meat to an optimum extent; 6) suction: using a vacuum press to suck and separate the dry-frozen shells and meat; and 7) packaging. By adopting the scheme, the river crab shell separation capacity is greatly improved, the domestic demand for river crab food is promoted, higher added values are obtained and a new growth point of China national economy is expected to be formed; and the problem of river crab resource wastage is improved at the same time.

Description

technical field [0001] The invention relates to a dry-freeze absorption method for small-sized river crab belly meat, which belongs to the technical field of food processing methods. Background technique [0002] At present, there is no separation technology of river crab shell and meat at home and abroad, and the market is blank. In recent years, my country is a big country in the production of river crabs. Among the 650,000 tons of river crabs in the country, those below 80 grams account for one-third. The quantity of deep processing is also less than 16,000 tons, and the remaining large amount of crabs are sold as cheap commodities, and some are made into feed, which causes great waste, especially the impact on environmental pollution. Contents of the invention [0003] The purpose of the present invention is to provide a method for sucking the belly meat of river crabs with a small size by drying and freezing in order to overcome the deficiencies in the prior art.
