Description
Technical field
Invention relates to small lobsters waste material complete processing, and particularly a kind of leftovers of crawfish is recycled technology.
Technical background
The present most enterprises of the tankage of China processing of aquatic products small lobsters do not carry out intensive processing, its tankage sell raising aquatic animals or are sold to workshop-based employing acid-base method and extract second-rate products such as shrimp shell element, and its production technique can produce serious pollution of area source to ecotope.
Summary of the invention
There is above-mentioned technical problem in the present invention in order to solve existing medicine, a kind of utilization ratio height is provided, has no side effect, the production technique discharge water recycles technology to a kind of leftovers of crawfish that ecotope does not produce pollution.
Technical solution of the present invention is: a kind of leftovers of crawfish is recycled technology, and its difference is: its steps in sequence is:
Step 1), the tankage of small lobsters are rubbed with machinery;
Step 2), the leftovers of crawfish after the rubbing that obtains in the step 1) is adjusted pH value to 7.0, ratio in tankage raw material substrate weight 0.3 ‰-2 ‰ adds papoid and stirring again, keep 50 ℃-60 ℃ of temperature then, thereby insulation obtained the mixed solution of shrimp shell, protein, fatty shrimp flavine in 2-4 hour;
Step 3), to step 2) mixed solution that obtains carries out filtering separation, isolate the mixing liquid and the shrimp shell of protein, fatty shrimp flavine, from protein, fatty shrimp flavine mixing liquid, extract proteins concentrate, fatty shrimp flavine respectively then, and discharge inorganic salts precipitation waste water.
By above scheme, described step 2) the maintenance temperature in is 52 ℃～58 ℃.
By above scheme, described step 2) the maintenance temperature in is 54 ℃～56 ℃.
By above scheme, the shrimp shell that obtains in the described step 3) is after overheated air seasoning is handled, again through forming powdery shrimp husk as raw material finished product after the mechanical disintegration.
By above scheme, the mixing liquid that obtains protein, fatty shrimp flavine in described step 3) constant temperature deactivation 30-40 minute under 85 ℃ of-90 ℃ of temperature condition, entering centrifugal device after the cooling carries out centrifugation with 800-1000 rev/min centrifugal rotational speed and handled 30-40 minute, thereby protein liquid is separated with fatty shrimp flavine, extract proteins concentrate finished product, fatty shrimp flavine finished product then.
By above scheme, in the described step 3), isolated protein liquid obtains the proteins concentrate finished product through extracting after pasteurization, the spraying drying successively.
By above scheme, described step 2) papoid that adds in is the papoid of 1,000,000 units/gram-2,000,000 units/gram.
The contrast prior art, the beneficial effect of technical solution of the present invention is:
This patent selects to be fit to the enzymic hydrolysis technology of leftovers of crawfish separation and Extraction, and leftovers of crawfish is converted to the protein of higher-value, fatty shrimp flavine, shrimp shell meal product.Three kinds of products produce different purposes separately, and wherein, the shrimp shell that the present invention recycles the technology generation also can be used as the raw material that extracts astaxanthin.Fat shrimp flavine also can obtain lipid acid, shrimp flavine through high temperature evaporation moisture content and separating treatment.
The discharge water environmentally safe that technology of the present invention produces, product are through the food inspection drug residue free, and product heavy metal content mensuration also meets state food hygienic safety standard.
1, the leftovers of crawfish raw material is fully utilized, and has improved the secondary value added of leftovers of crawfish;
2, the product after enzymic hydrolysis is handled has no side effect, and can not influence food safety, does not produce heavy metal, drug residue;
3, the inorganic salts precipitation waste water of leftovers of crawfish extraction process discharge of the present invention does not produce pollution of area source to ecotope;
4, to reclaim the end-use scope such as protein concentrate, shrimp shell, fatty shrimp flavine of generation wide in the present invention.
This patent has solved the difficult problem of aquatic products small lobsters processing industry tankage intensive processing, and production cost is low, increases the secondary value added of aquatic products processing industry byproduct, greatly reduces the pollution of area source problem of leftovers of crawfish to ecotope.
