Abstract

The invention provides a method for processing live crabs, which comprises the following steps: live crabs are soaked in a purifying fresh water tank with circularly flowing fresh water for 30 to 40 minutes, and then are soaked in ice water at a temperature between 10 and 15 DEG C so as to allow the live crabs to be in a sleeping state; the live crabs subjected to ice-water soak are sent into a microwave oven at a high temperature between 130 and 150 DEG C by use of a conveyor belt so as to be cooked; the cooked crabs are cooled to be between 5 below zero and 40 DEG C by use of ice blocks; and the crabs are subjected to causal inspection, bagged, sealed and packed into boxes. Compared with the crabs processed by the prior live-crab cooking process, legs of the crabs processed by the method are not easy to fall off so as to meet the requirements of consumers on the appearance and taste of foods.

Description

The processing method of a kind of crab that lives

Technical field

The present invention relates to the processing method of a kind of crab that lives, particularly relate to a kind of processing method that can discharge a kind of crab that lives of the impurity in the crab body, product phase crab pin difficult drop-off, that keep crab.

Background technology

Crab is not only delicious, and nutritious, and crab contains rich in protein and trace element, and health is had good tonic effect.Have the proverb of " a dish crab, top half-prepared meals ".Since improve constantly to people's quality of life, increasing to the seafood demand.In recent years, sea crab (Sea crab) market was very good, and China's Coastal Areas output is big.The sea crab that China North Sea abounds with (Sea crab) is owing to be grown under the seawater below 20 meters, and sea water quality is good, and meat is soft, delicious flavour, contain high protein and low than fresh water or shallow sea crab cholesterol level, is received by the market.But traditional sea crab (Sea crab) market mainly is to sell based on the crab that lives.As everyone knows; the keep-alive of sea crab (Sea crab), fresh-keeping be present one technical barrier; reason is also can only survive 1-2 days under the common technique oxygen supply condition at present after sea crab (Sea crab) is fished for; nutritive value and the original mouthfeel of crab have not only been lost; and sea crab after death (Sea crab) is because cell is more fragile than fish, shrimp; meat is very easily corrupt, rotten, can not take food, and has had a strong impact on the market sale of sea crab (Sea crab).In order to make sea crab (Sea crab) in landlocked market sale, people adopt traditional freezing method to be sold inland then, but the sea crab after freezing (Sea crab) has been destroyed its cell, nutrition and mouthfeel, and make ripe back mouthfeel and carnification gets soft.Traditional ripe method of crab system alive, the crab pin of making after ripe often comes off, and has influenced the product phase of ripe crab, fails to satisfy the product mutually requirement of consumer to food; In addition because water quality is subjected to environmental pollution, particularly the neritic province domain seawater contains many harmful impurity, crab is the biology that moves in the water, many parasitic bacterias and impurity have been adsorbed in its crust body, if processing technology is unreasonable, just these may be brought into and make in the ripe crab body, health is produced harmful effect.

Summary of the invention

The objective of the invention is at the deficiencies in the prior art part, provide a kind of and other impurity can be discharged the crab body, can keep the crab processing method a kind of alive of the product phase of crab again.

Technical scheme of the present invention is:

The purged with fresh water of a, the crab that lives: utilize the fresh water that the purifies crab that to live to soak 30-40 minute, in this process in order to keep the crab activity, be provided with the soaking and washing pond, purifying fresh water circulates in service sink, live crab owing to grow at seawater, thereby fresh water incompatibility amount of exercise in fresh-water pool is improved rapidly, sucking a large amount of fresh water constantly spues from inside to outside, equal nature and clean internal organ, the impurity that keeps in the crab body can be told, can reach again and not only keep the active of crab but also parasitic bacteria and the impurity discharge that keeps in the crab body can be of value to the health of human body;

The frozen water of b, the crab that lives soaks: behind the ripe crab alive of tradition system, the crab pin often comes off influences its outward appearance, in order to allow crab prevent that the crab pin from coming off after system is ripe, keeps original shape, soaks with the frozen water of temperature at 10-15 ℃, and purpose is to allow crab alive be in sleep state.In order to reach batch process, present technique technology is provided with the frozen water fermentation vat in this process.The Manufacturing Worker soaks pool side at frozen water and screens, the crab alive that screens is put into conveyer belt, and to enter temperature be that 130-150 ℃ micro-wave oven system is ripe, be in dormant crab alive and in the ripe process of high temperature system, be in static state, reach the ripe back of system crab pin and do not take off, maintain the original state;

The ice block cooling of c, ripe crab: will make ripe crab with ice cube and be cooled to-5 ℃-40 ℃;

D, sampling observation pack, seal the dress box with qualified finished product and get final product.

The invention has the beneficial effects as follows the external form that the ripe crab of being processed into is kept perfectly, crab pin difficult drop-off can despumation, and relative environmental protection can keep the taste of crab and nutrition and retention time is long, processing method is simple, easy to operate.

The specific embodiment

Below by specific embodiment the present invention is further described, but does not limit the scope of the invention.

Embodiment 1

The fresh water of a, the crab filtration, purification of living: utilize fresh water after the filtering crab that will live to soak 30 minutes, in this process in order to keep the crab activity, be provided with the soaking and washing pond, purifying fresh water circulates in service sink, live crab owing to grow at seawater, thereby fresh water incompatibility amount of exercise in fresh-water pool is improved rapidly, sucking a large amount of fresh water constantly spues from inside to outside, impurity of keeping in the crab body etc. is told naturally, reach and not only keep the activity of crab but also parasitic bacteria and the impurity discharge that keeps in the crab body can be of value to the health of human body;

B, the crab frozen water of living soak: behind the ripe crab alive of tradition system, the crab pin often comes off influences its outward appearance, in order to allow crab prevent that the crab pin from coming off after system is ripe, keeps original face shaping, soaks with the frozen water of temperature at 10 ℃, and purpose is to allow crab alive be in sleep state.In this process,, be provided with the frozen water fermentation vat in order to reach batch process.The Manufacturing Worker soaks pool side at frozen water and screens, and the crab alives that screens is put into conveyer belt, and to enter temperature be that 130 ℃ micro-wave oven system is ripe, is in dormant crab alive and is in static state in the ripe process of high temperature system, make ripe crab pin afterwards and do not take off, maintenance outward appearance original state;

C, ripe crab ice block cooling: will make ripe crab with ice cube and be cooled to-5 ℃;

Embodiment 2
