Description

A fermentation mixer

Technical Field

The utility model relates to the technical field of fertilizer fermentation, in particular to a fermentation mixer.

Background Art

Microbial fertilizer is commonly known as bacterial fertilizer, or bacterial fertilizer for short. It is a bacterial agent made by separating beneficial microorganisms from the soil and artificially selecting and breeding them. Microbial fertilizer is a kind of auxiliary fertilizer. The fermentation of microbial fertilizer requires a fermentation mixer, which mixes the raw materials of the fertilizer to improve the fermentation efficiency. However, the existing fermentation mixer has the following disadvantages:

Generally, existing fermentation mixers use a single stirring rod to stir and mix fertilizers, which is difficult to fully mix in a short time, resulting in low mixing efficiency. Secondly, in order to accelerate fertilizer fermentation, 30-40° water is generally added to the fertilizer before stirring as the starting temperature of fertilizer fermentation, thereby improving the fermentation efficiency. Heat is generated during the subsequent fertilizer mixing and fermentation process, and the heat cannot be recycled, resulting in waste. Therefore, the utility model proposes a fermentation mixer.
