Bio-organic fertilizer with chitin and preparation method of bio-organic fertilizer

Abstract

The invention relates to the field of organic fertilizers, and in particular, relates to a bio-organic fertilizer with chitin and a preparation method of the bio-organic fertilizer. A shell processor is used in the preparation method and comprises a machine shell, a motor and a stirring column; the motor is fixedly connected to the outer portion of the machine shell; a first rotating disc is fixed on an output shaft of the motor; a second rotating disc is rotationally connected to the position, close to the bottom of the machine shell, in the machine shell; a transmission belt is connected between the first rotating disc and the second rotating disc; the top of the second rotating disc is fixedly connected with the stirring column; cutters are uniformly arranged on the surface of the stirring column; and a spray head is fixedly connected to the interior of the machine shell. Mechanical rapid processing of shrimp shells is effectively achieved, edible oil and seasonings on the surfaces of the processed shrimp shells can be filtered out, after the shrimp shells are smashed, the occupied space is greatly reduced, the preservation time of the shrimp shells is prolonged, and the single-time transportation amount of the shrimp shells is greatly increased.

Description

Technical field [0001] The present invention relates to the field of organic fertilizer, in particular a bio-organic fertilizer having chitin and its preparation method. Background technique [0002] Crayfish shrimp shell is the main component of chitin, is a natural biological macromolecular compound to extract chitin from shrimp shells, in the last century there have been corresponding processing enterprises. [0003] A plant according CN107129353A organic fertilizer produced by use of straw, the straw plant utilizing the invention is the production of organic fertilizer, effectively reducing the production cost of raw materials, the cost can be reduced by 50% -60%, the present invention is from canola straw wheat straw extract and straw into organic fertilizer, the fertilizer can effectively reduce environmental pollution. [0004] However, the prior art, from small lobster shrimp shell extract chitin, you need to first clean shrimp, in order to reduce the cost of shrimp, lobs...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, to extract chitin from the shrimp shells of crayfish, the shrimp shells need to be cleaned first. In order to reduce the cost of shrimp shells, in lobster restaurants and food stalls, the leftover shrimp shells eaten by diners can be used as raw materials, but Because these shrimp shells have been cooked, they contain a lot of seasoning and oil. If they are not processed and transported directly, the summer weather is hot, and the shrimp shells will stink in a short time, which will affect the transportation, and the manufacturers need to recycle the shrimp shells every day, and the recovery cost higher question
