What are the fermentation methods of organic fertilizer?
Date:2019/10/16
There are three ways to ferment organic fertilizer. One is fermentation in fermentation tank, the other is compost fermentation, and the third is tower fermentation.
1. Fermentation in fermentation tank.
The main technological process is to mix chicken manure, peat and sawdust into the cement tank, use the composting equipment to aerate and ferment, smash them after fermentation, and then screen and pack them into products.
The advantages of this mode are: simple and convenient production process, less investment and low production cost.
The main disadvantages are low nutrient content and high water content, which can not meet the requirements of commercialization. Low level of continuous factory production and long production cycle. Chinese style
2. Direct composting.
The main fertilizer production process is to mix chicken manure and straw or peat, pile up about 1 meter high, use high-temperature compost, regularly flip aeration fermentation, after fermentation as a product.
The advantages of this mode are: simple production process, less investment and low cost.
The main problem is that the product stacking time is too long, affected by various external conditions, and the product quality is difficult to guarantee. The degree of continuous production is not high and the production cycle is long. Chinese style
The main technological process is to mix chicken manure with sawdust and other auxiliary materials, and then connect with biological bacteria agent. At the same time, the tower body automatically flips and ventilates, and uses biological growth to accelerate chicken manure fermentation and deodorization. After a fermentation cycle, the product is basically coming out of the tower body.
This mode has the advantages of small floor area, low energy consumption, small pollution and high degree of industrialization, but its existing problems are:
The moisture content of the product can not meet the requirement of commercialization.
At present, the operation of the process flow is not smooth, resulting in a large increase in labor costs, and the output can not meet the design requirements.
The corrosion of equipment is serious, which restricts its further development.
