Embodiment 1

[0030] With corn, wheat, rape, flax, beans and other crop straws and porous mineral soil as the main adsorption and flocculation materials, the non-rotten corn, wheat, rape, flax, beans and other straws are mechanically crushed into 10 meshes, according to The ratio of 1% by weight is added to the potato dregs produced in the processing of potato starch such as potatoes, stirred and placed at room temperature for 1 hour, and then put into a screw press to be squeezed and separated. The solid slag with a water content of about 70% is separated as a mixed solid slag; the liquid separated by pressing is added into 0.1% by weight mineral soil containing porosity and can be used as a feed additive and stirred for 5 minutes. After standing at room temperature for 0.5h, enter the horizontal screw centrifuge for separation, collect solid materials as coagulated solid materials, and mix them with mixed solid slag as protein feed raw materials. They can be directly used as protein feed a...

[0032] With corn, wheat, rape, flax, beans and other crop straws and porous mineral soil as the main adsorption and flocculation materials, the non-rotten corn, wheat, rape, flax, beans and other straws are mechanically crushed into 60 meshes, according to The ratio of 6% by weight is added to the potato dregs produced in the processing of potato starch such as potatoes, stirred and placed at room temperature for 12 hours, and then put into a screw press to be squeezed and separated. Separate the solid slag with a water content of about 70% as a mixed solid slag; add the liquid separated by pressing to 0.6% by weight of mineral soil containing porosity that can be used as a feed additive and stir for 20 minutes. After standing at room temperature for 2 hours, enter the horizontal screw centrifuge for separation, collect solid materials as coagulated solid materials, and mix them with mixed solid slag as protein feed raw materials. They can be directly used as protein feed after...

Embodiment 3

[0034] Using broad bean straw and porous mineral soil as the main adsorption and flocculation materials, the non-rotten broad bean straw is mechanically crushed into 20 meshes, and added to the potato dregs produced in the processing of potato starch such as potatoes in a proportion of 3.75% by weight, and stirred After standing at room temperature for 6 hours, enter the screw press to press and separate. The solid slag with a water content of about 70% is separated as a mixed solid slag; the liquid separated by pressing is added into 0.2% by weight mineral soil containing porosity and can be used as a feed additive and stirred for 15 minutes. After standing at room temperature for 1 hour, enter the horizontal screw centrifuge for separation, collect solid materials as coagulated solid materials, and mix them with mixed solid slag as protein feed raw materials. They can be directly used as protein feed after being compacted and sealed for storage, or through aerobic fermentatio...

Abstract

The invention discloses a protein feed raw material, which is prepared by mixing mixed solid residues with a coagulated solid material. The invention has the beneficial effects that: the protein feed raw material and the preparation method and application thereof, provided by the invention, have the advantages that: (1) the treatment process flow, equipment investment and energy consumption are reduced, and the treatment efficiency is increased; (2) an additive used has good flocculation, adsorption and retention effects, and is cheap and safe; (3) the problems of difficulty in piling and storing wet potato residues and overlarge occupied field are solved; (4) a collected solid material is used for producing a feed, and treated water can be used for washing potatoes, so that the water consumption of starch processing is reduced; (5) the recovery rate of the crude proteins is up to 50-75 percent, the COD (Chemical Oxygen Demand) is lowered by over 50 percent, the recovered solid material can be taken as the protein feed raw material, and the rough protein can be up to 10.0-14.5 percent (dry base); and (6) the treatment process does not have any special requirement on the environmental temperature, a good effect is achieved at the temperature of 5-10 DEG C, and the treatment energy consumption is lowered.

Description

technical field [0001] The invention relates to a protein feed raw material and its preparation method and application. Background technique [0002] A large amount of wet potato residue and waste water are produced in the processing of potato starch, and these by-products contain a large amount of organic matter such as protein and polysaccharide. Potato residues contain organic matter such as pectin, protein, starch, etc., have high viscosity, strong water holding capacity, and are difficult to squeeze, dry and dehydrate. At present, the main treatment method for wet potato residues is direct intermittent pressing and dehydration followed by drying, but the dehydration efficiency is low, the drying speed is slow, and the energy consumption is high. The content of organic nutrients and COD value (chemical oxygen demand) in protein water are too high, and the direct discharge pollutes the environment. Although the existing biochemical treatment methods can achieve dischar...
