Problems solved by technology

[0006] The present invention aims at the harsh treatment conditions and high labor intensity of the existing animal crustacean treatment technology, which consumes a large amount of strong acid, strong alkali and fresh water resources, and cannot maximize the utilization of resources, instead producing a large amount of pollutants and causing serious secondary pollution. and other shortcomings, a new treatment method for animal crustaceans is provided, which can not only recover and comprehensively utilize biologically active substances such as protein, fat, pigment, and chitin in animal crustaceans during the treatment process, but also has no Pollution generation, simple operation and convenient management
[0007] The present invention also aims at the disadvantage that the prior art cannot use the animal crustaceans formed by catering industries such as hotels and guesthouses to consume the crustaceans (due to the small quantity and lack of economy of utilization), and can only be treated as garbage for landfilling, and provides A device integrating animal crustacean collection and treatment methods, which is easy to recycle animal crustaceans

Embodiment 1

[0037] Embodiment 1: the preparation of main product chitin

[0038] In the device, add 500 kg of shrimp shells, heat and cook at 100°C, and then cool to 25°C; add 1000g of neutral protease, appropriate amount of lactic acid bacteria culture solution and glucose and mix in 1.5 tons of clear water in a certain proportion, Wherein lactic acid bacteria powder: glucose: animal crustacean: clear water=10 2 Live bacteria: 100kg: 1000kg: 3000kg, after stirring for 5 minutes, seal, ferment at 20°C, stir from time to time, and separate the solid and liquid after 10 days. The fermentation liquid contains protein, polypeptide, amino acid and calcium lactate. After drying, high calcium, Feed additive of high quality protein. The solid chitin is washed with water and dried to obtain chitin. The washing liquid is used for the next fermentation water. There is no waste liquid and waste water discharge in the whole production process.

Embodiment 2

[0039] Embodiment 2: the preparation of main product chitosan

[0040] In the device, add 500 kg of shrimp shells, heat and cook at a temperature of 104°C, then cool to 25°C; mix 500g of neutral protease, 500g of chitin deacetylase, and an appropriate amount of lactic acid bacteria culture solution in a certain proportion In 1 ton of clear water, wherein lactic acid bacteria culture solution: glucose: animal crustacean: clear water = 10 6 Live bacteria: 300Kg: 1000kg: 2000kg, sealed after stirring for 10 minutes, fermented at 25°C, stirred from time to time, and separated from solid and liquid after 7 days. The fermented liquid contains protein, polypeptide, amino acid, and calcium lactate. The fermented liquid is mixed with bean cake, cottonseed cake, etc., dried, crushed, mixed and granulated to obtain high-calcium, high-nitrogen feed. The solid chitin is washed with water and dried to obtain chitosan. The washing liquid is used for the next fermentation water. There is n...

Embodiment 3

[0041] Embodiment 3: the preparation of feed type product

[0042] In the device, add 500 kg of shrimp shells, heat and cook at 105°C, then cool to 45°C, mix 1500g of acid protease, 1000g of cellulase, appropriate lactic acid bacteria culture solution and glucose in a certain proportion. 2 tons of clear water, add 500 kg of shrimp shells, wherein lactic acid bacteria culture solution: glucose: animal crustacean: clear water = 10 9 Live bacteria: 300Kg: 1000Kg: 4000Kg Stir for 3 minutes, seal, ferment at 45°C, stir from time to time, separate after 5 days. The fermented liquid contains protein, polypeptide, amino acid, pigment, fatty acid, glycerin, polysaccharide, monosaccharide and calcium lactate, and the fermented liquid is filled into a container as a liquid feed additive. There is no waste liquid and waste water discharge in the whole production process.

Abstract

This invention provides a method and a device for processing animal testa substances including the following steps: 1, putting animal testa substances in a fermentation device, 2, putting 0.1-0.4% enzyme preparation with the function of degration albumen, a microbe preparation with the fermentation function and microbe fermentation base materials in the device to be mixed and fermented in seal, 3, filtering said fermentation liquid and separating solid and solution to be dried to get the product. A device is disclosed including a shell, a cover on the top of the shell, a mixing rod with mixing blades is set in the shell and one end of the rod extends outside of the rod through the cover, an outlet is set at the bottom and a valve is set at the outlet.

Description

technical field [0001] The invention belongs to the field of resources and environment, and in particular relates to a method and device for treating animal crustaceans. Background technique [0002] Crustaceans represented by shrimps, crabs and insects not only have many kinds, but also have large biomass and abundant resources. They are one of the main sources of animal protein for human beings to survive. In the process of exploiting and utilizing crustacean protein, a large amount of animal crustaceans will be produced. At present, animal crustaceans are mainly treated as landfill, dried as feed, and prepared by chemical treatment to prepare chitin. [0003] Fresh animal crustaceans are rich in protein, fat, pigment, chitin and other biologically active substances, and they are treated as garbage for landfill, which not only wastes precious resources, but also produces a large amount of corruption and harmful substances in the process of collection, transportation and la...
