Organic fertilizer raw material proteolysis post-treatment method

Abstract

The invention relates to the field of organic fertilizer production and particularly relates to an organic fertilizer raw material proteolysis post-treatment method. The method comprises the followingsteps: (1) mixing minced leftovers with water, adding strains for enzymolysis for a period of time, and then preparing a filtering device which comprises an inner barrel, a blockage clearing block slidably arranged in the inner barrel, and a material containing block rotatingly arranged in the inner barrel, wherein filtering holes are formed in a side wall of the inner barrel; (2) putting the leftovers into the material containing block, allowing the blockage clearing block to push the material containing block to move while the material containing block rotates in the inner barrel to filterthe leftovers, and allowing the leftovers in the material containing block to make contact with different positions of the side wall of the inner barrel; (3) filtering residues adhering to the side wall of the inner barrel when the blockage clearing block pushes the material containing block to move, and (4) sucking out the residues adhering to the interiors of the filtering holes through a negative pressure difference formed between an upper space and a lower space of the blockage clearing block in step (3). When the technical scheme is adopted, the leftovers can be filtered in batches.

Description

technical field [0001] The invention relates to the field of organic fertilizer production, in particular to a post-treatment method for organic fertilizer raw material proteolysis. Background technique [0002] The nutrients of liquid organic fertilizers come from animals, plants or minerals. The raw materials for the production of organic fertilizers include animal leftovers. By hydrolyzing the protein in the leftovers, proteinaceous organic nitrogen is converted into water-soluble organic nitrogen and available nitrogen. [0003] Before hydrolyzing the protein in the leftovers, it is necessary to enzymatically hydrolyze the leftovers to obtain an enzymatic solution, and then filter the enzymatic solution to obtain a filtrate containing protein; The enzymolysis solution contains incompletely decomposed scraps. Due to the small pore size of the microporous membrane, the filtration speed is slow, and the membrane is easily blocked. It needs to be cleaned repeatedly during th...

[0003] Before hydrolyzing the protein in the leftovers, it is necessary to enzymatically hydrolyze the leftovers to obtain an enzymatic solution, and then filter the enzymatic solution to obtain a filtrate containing protein; The enzymolysis solution contains incompletely decomposed scraps. Due to the small pore size of the microporous membrane, the filtration speed is slow, and the membrane is easily blocked. It needs to be cleaned repeatedly during the filtration process, which is inconvenient to operate and is not conducive to large quantities of scraps. material filtration
