Production system and preparation method of microbial fertilizer

Abstract

The invention discloses a production system of a microbial fertilizer. The production system comprises a material mixing device, a fermentation tank, an aging device, a batching device, an auxiliary material mixing device, a drying device, a crushing and screening device, a finished product packaging device, a liquid fertilizer collecting device and a steam device; the steam device, the fermentation tank and the liquid fertilizer collecting device are sequentially connected to form a liquid fertilizer production line; and the material mixing device, the fermentation tank, the aging device, the crushing and screening device, the batching device, the auxiliary material mixing device, the drying device and the finished product packaging device are sequentially connected to form the solid fertilizer production line. In the invention, the liquid fertilizer and the solid fertilizer are simultaneously produced through the fermentation tank, so that the value of the raw materials is fully exerted, and the waste of the raw materials is not caused. Fermentation is carried out in the fermentation tank, decomposition is uniform and thorough in the fermentation tank, and grass seeds and pathogenic bacteria are thoroughly killed. By adding the microbial functional fungicide and trace elements, the defect of single component of the microbial fertilizer is overcome.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a production system and preparation method of microbial fertilizers. Background technique [0002] Microbial fertilizer refers to a type of compound of specific functional microorganisms and organic materials that are mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. effect fertilizer. At present, the technology of the industry is backward, the process is simple, and the technical indicators such as the effective number of viable bacteria and water content of the microbial fertilizer produced cannot meet the requirements of the industry. At the same time, in the production process of fertilizers, raw materials need to be aged for a period of time. During the aging process, some raw materials are easy to agglomerate, which makes the effect of aging poor after agglom...

Problems solved by technology

At present, the technology of the industry is backward, the process is simple, and the technical indicators such as the effective number of viable bacteria and moisture of the microbial fertilizer produced cannot meet the requirements of the industry

At the same time, in the production process of fertilizers, the raw materials need to be aged for a period of time. During the aging process, some raw materials are easy to agglomerate, which makes the effect of aging poor after agglomeration. In the prior art, all Use a forklift to turn over and throw the materials in the aging process. This way of turning and throwing makes the agglomerated materials still lumpy, and the effect of aging cannot be achieved.
