CN102578200A - Small river crab belly meat dry-freezing and suction method - Google Patents

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

A kind of small dimension river crab tripe jerky freezes the absorption method

Technical field

The present invention relates to a kind of small dimension river crab tripe jerky and freeze the absorption method, belong to the food-processing method technical field.

Background technology

Domestic and international now no river crab shell meat isolation technics temporarily, the market vacancy, China is the big country of river crab output in recent years; Wherein account for 1/3rd below 80 grams in the 650000 tons of river crabs in the whole nation, this part crab is called the crab of stopping over, and the quantity that is used for deep processing is 1.6 ten thousand tons of less thaies also; The crab of stopping over that all the other are a large amount of is used as cheaper commodity and sells; What have is made into feed, has caused great waste, particularly to the pollution effect of environment.

Summary of the invention

The present invention seeks to provides a kind of small dimension river crab tripe jerky to freeze the absorption method for the deficiency that overcomes prior art.

For achieving the above object, the technical scheme that the present invention adopts is: a kind of small dimension river crab tripe jerky freezes the absorption method, comprises following steps:

1., raw material is handled: select the river crab of the little stature of less than 80 grams for use, do raw material acceptances such as sense organ, outward appearance;

2., pre-treatment: crab is decomposed, and crab leg, crab tripe meat are separately; Crab tripe meat decomposes, and crab tripe meat side is divided into two;

3., dry: the crab tripe meat that cuts is put into drying room dry, dry up moisture with fan; Drying room is sterilized with sterilamp;

4., freezer: add " accelerated freeze dryer " equipment in the freezer, temperature of ice house is controlled at about subzero 35 degree, and crab tripe meat is put into the freezer quick-frozen;

5., dry freeze: crab tripe meat was put into the freezer dry freeze 3 hours, and crab meat is little by 1/5th before than dry freeze after the dry freeze, and shell meat separates the best basically;

6., draw: will divide the crab shell crab meat after doing to draw separation with the vacuum pressure machine;

7., packing: after crab tripe meat draw to separate, with weigh one bag of 500g of crab tripe meat, one the case 6 bags, put into freezer.

Beneficial effect of the present invention is mainly reflected in: small dimension river crab tripe jerky of the present invention freezes the absorption method; Improved the river crab production capacity of peeling off greatly; Help promoting river crab food domestic demand, obtain higher added value, will form the Chinese national economy new growth point; Improve the wasting of resources problem of river crab simultaneously.
