What is the specific process of fermenting manure organic fertilizer by organic fertilizer processing equipment

To make organic fertilizer from pig manure, chicken manure, cow manure, and sheep manure, the important link is fermentation. So what is the specific process of fermenting manure and organic fertilizer by organic fertilizer processing equipment? Let’s take a look.

1.The original high-temperature fermentation equipment is used for pre-aerobic fermentation. The temperature during the pre-fermentation is between 20°C and 70°C. Fermentation is carried out through organic fertilizer equipment. When the ratio of material nitrogen to carbon, moisture, and conditions are suitable, microorganisms begin to treat organic fertilizer. The raw materials are decomposed.

The continuous heat generated in the decomposition process increases the temperature of the organic fertilizer fermentation raw material pile to about 70°C. At this time, the microbial flora multiplies, and the decomposition and fermentation speed of the organic fertilizer raw materials is greatly accelerated. In this stage, the eggs and germs in the raw materials are gradually killed. As the heat accumulates, when the temperature exceeds 70°C, the low-temperature microorganisms will die, the activity of the high-temperature bacteria will also decrease, and the fermentation speed will slow down.

2.Turn over the volatilized water, and turn over the organic fertilizer fermentation raw materials to prevent the fermentation speed from slowing down due to excessive temperature.

3.The original aeration tank is used for the cooling period (heat preservation stage). With the end of the fermentation process, the temperature of the fermentation reactor is gradually reduced until it is slightly higher than the room temperature, and then sealed and stored.
