Rapid production process of organic fertilizer

Abstract

The invention discloses a rapid production process of an organic fertilizer, which includes the following steps: (1) pre-fermentation that specifically includes the following working procedures: (1-1) mixing of raw materials and auxiliary materials, (1-2) drying and (1-3) pre-fermentation; (2) fermentation; (3) sampling and testing that are conducted according to NY525-2002 standards, and follow-up operation after testing results are qualified; (4) grinding and screening, namely grinding and screening semi-finished products sampled and tested to be qualified, and putting the semi-finished products into a warehouse for the semi-finished products; (5) post-fermentation: piling up the semi-finished products with moisture content dropping to 25-30% wt, and conducting post-fermentation while preventing the rain; (6) packaging, namely mechanical or manual packaging, sealing and palletizing; and (7) loading and delivery, namely mechanical or manual loading of packaged products, and delivery.The rapid production process of the organic fertilizer can ensure high drying efficiency of the raw materials, the auxiliary materials and the semi-finished products, has the advantages of low energyconsumption, deodorization, and good effect in killing flies and maggots, and saves fermentation time.

Description

technical field [0001] The invention relates to the field of organic fertilizer production, in particular to a rapid production process of organic fertilizer. Background technique [0002] In the existing technology, in the production of organic fertilizers and bio-organic fertilizers in the northern region, raw materials such as chicken manure and cow manure tend to have high water content, and it is difficult to control the supply of auxiliary materials such as sawdust around the production plant, resulting in drying of fermentation products. Low efficiency, poor deodorization and fly maggot killing effects, high energy consumption and long time consumption when producing qualified organic fertilizer products, ammonia gas is easily generated during the production process, the fertilizer efficiency of the finished fertilizer is low, and the organic matter content of the finished fertilizer is easily lower than 30%, etc. question. Contents of the invention [0003] Aiming...
