The pig manure, chicken manure, cattle manure and sheep manure from the farm are used as organic fertilizer. The important link is fermentation treatment. What is the specific process for the organic fertilizer processing equipment to ferment manure and organic fertilizer? Let's have a look.
1、 The original high-temperature fermentation equipment is used for aerobic fermentation in the early stage. The temperature of the early stage fermentation is between 20 ℃ and 70 ℃. The fermentation is carried out through the organic fertilizer equipment. When the nitrogen carbon ratio, water content and conditions of the material are appropriate, microorganisms begin to decompose the organic fertilizer raw materials.
The constant heat generated in the decomposition process makes the temperature of the fermentation raw material pile of organic fertilizer rise to about 70 ℃. At this time, the microbial flora multiplies in large numbers, greatly accelerating the decomposition and fermentation of organic fertilizer raw materials. In this stage, the eggs and bacteria in the raw materials are gradually killed. With the accumulation of heat, when the temperature exceeds 70 ℃, the low-temperature microorganisms will die, the activity of high-temperature bacteria will also decrease, and the fermentation speed will slow down.
2、 Dump the volatile water, and turn over the fermentation raw materials of organic fertilizer to prevent the fermentation speed from slowing down due to high temperature.
3、 The original aeration tank is used in the cooling period (heat preservation stage). With the end of the fermentation process, the temperature of the fermentation pile gradually decreases until it is slightly higher than the room temperature, and then it is sealed for storage.
