A kind of preparation method of bio-organic fertilizer with chitin

Abstract

The invention relates to the field of organic fertilizers, in particular to a bio-organic fertilizer with chitin and a preparation method thereof, wherein a shell processing machine is used in the preparation method, including a casing, a motor and an agitating column; the outside of the casing is fixedly connected There is a motor; the output shaft of the motor is inherently a first turntable; the inside of the casing is close to the bottom of the casing and is rotatably connected to a second turntable; a transmission belt is connected between the first turntable and the second turntable; the The top of the second turntable is fixedly connected with a stirring column; the surface of the stirring column is provided with evenly arranged cutters; the inside of the casing is fixedly connected with a nozzle; effectively realizing the mechanized and rapid processing of shrimp shells, the processed shrimp The edible oil and seasoning on the surface of the shell will be filtered out, and after the shrimp shell is crushed, the occupied space is greatly reduced, the storage time of the shrimp shell is improved, and the single transportation volume of the shrimp shell is greatly increased.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a method for preparing bio-organic fertilizers with chitin. Background technique [0002] The main component of crayfish shells is chitin, which is a natural biopolymer compound. Chitin is extracted from shrimp shells, and corresponding processing and production enterprises have emerged in the last century. [0003] According to CN107129353A, a kind of organic fertilizer produced by using plant stalks, the organic fertilizer produced by using plant stalks in this invention effectively reduces the production cost of raw materials, and can reduce the cost by 50%-60%. , Wheat stalks are extracted, and the stalks are converted into organic fertilizers, which can effectively reduce the pollution of fertilizers to the environment. [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 t...

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
