Organic fertilizer production line helps solve the problem of waste
Organic fertilizer production line is the equipment for batch production of organic fertilizer, covering all the equipment from the collection of organic fertilizer raw materials to the packaging and sales of organic fertilizer. The organic fertilizer production line can effectively solve the environmental pollution caused by organic wastes from livestock and poultry industry, improve the safety and quality of agricultural products, and lay a good foundation for human beings to eat green food and organic food. The ecological environmental benefits are extremely significant.
The process of making organic fertilizer
1. Preparation of raw materials and accessories
Choose a flat ground without ponding to stack livestock manure and auxiliary materials separately. Generally, granular or powdery wheat bran and peanut shell powder are used as the main auxiliary materials. If corn straw and cotton orange stalk are used as auxiliary materials, they should be cut into 5-10 cm length first. Too long will make it inconvenient to stir. The purpose of adding excipients is to adjust the water content and C / N ratio of chicken manure, and increase the air permeability of fermentation products.
2. Operation steps
Spread the bacteria evenly on the prepared chicken manure and stir evenly. During the organic fertilizer production process, the moisture content of livestock manure should be adjusted to about 60%. If the water content is too high, it is necessary to sprinkle wheat bran, corn straw and other auxiliary materials on livestock manure to reduce the water content of raw materials; if the water content is too low, it is necessary to add fresh raw materials or sprinkle some water. The stirred materials are stacked on the fermentation platform, and the height is about 1-1.2m.
3. Management of fermentation process
In the fermentation process, it is very important to control the temperature. If the temperature is too low, it can not reach the maturity standard; if the temperature is too high, the nutrients of compost are easy to lose. When the temperature reaches about 60 ℃, it is necessary to turn the stack properly. The organic fertilizer production plant cost is hundreds of thousands to millions.
Requirements of fermentation temperature and time:
After composting, the raw materials enter the first fermentation stage. It will automatically heat up to 55 ℃ for 5 to 7 days, then it can kill most of the parasite eggs and harmful bacteria, reaching the harmless treatment standard. After 2 to 3 days or so, turn the pile once, which is conducive to ventilation, heat dissipation and even decay. After 7-10 days of fermentation, the temperature in the compost will drop to below 40 ℃. At this time, the color of bio organic fertilizer will turn to dark brown or yellowish brown. There are a lot of white hyphae on the surface of the organic fertilizer inside the compost, which has no odor and slight ammonia odor. This meets the maturity standard and can be directly used as base fertilizer or topdressing in the field.
