The intelligent high-temperature aerobic fermentation treatment process is to mix organic waste and biomass (pulverized sawdust, rice husks, corn stalks, corn cob, peanut shells, etc.) and backmix materials in a certain proportion, and enter the treatment system with fermentation conditions. Oxygen is continuously supplied to the material through the high-pressure air supply system. Under the action of aerobic fermentation bacteria, the organic matter is continuously decomposed, resulting in a large amount of high temperature, which promotes the evaporation of water in the material, and at the same time kills pathogens, parasites, and impurities under high temperature conditions. Grass seeds can achieve the purpose of harmlessness, reduction and stabilization; the fermented materials can be used as organic fertilizer raw materials and landscaping to realize resource utilization.

 

Chicken manure aerobic fermentation system is an integrated complete set of equipment for processing livestock and poultry manure, domestic sludge, kitchen waste and other organic wastes. It mainly uses the activity of microorganisms to biodecompose and decompose the organic matter in the waste, realize the reduction, harmlessness and stabilization, and processing chicken manure into fertilizers, so as to realize the utilization of resources.

 

Aerobic fermentation tank equipment is mainly composed of fermentation chamber, feeding and lifting system, high-pressure air supply system, spindle drive system, hydraulic power system, automatic discharge system, deodorization system and automatic control system.

 

Aerobic fermentation equipment process flow

 

The intelligent high-temperature aerobic fermentation treatment process includes four processes: mixing and tempering, feeding, aerobic fermentation, and automatic discharging

 

(1) Mixing part

 

The mixing part is to mix excrement or organic waste with a high moisture content of about 75% with biomass and fermentation bacteria according to a certain proportion, and adjust the moisture content, C:N, air permeability, etc. to achieve fermentation conditions. If the moisture content of the raw material is 55-65%, it can be directly put into the tank for fermentation. You can ues a compost dryer to dry your manure.

 

(2) Aerobic fermenter part

 

The process can be divided into a rapid heating stage, a high temperature stage, and a cooling stage.

 

The material enters the fermenter and is rapidly decomposed within 24-48 hours under the action of aerobic bacteria, and the heat released makes the temperature of the material rise rapidly. Through the air supply and aeration system, oxygen is evenly supplied to the fermentation tank to meet the oxygen demand in the fermentation process, so that the material is fully fermented and decomposed, and the high temperature stage is maintained for 5-7 days. When the decomposition rate slowly decreased, the temperature gradually decreased to below 50 degrees. The entire fermentation process lasts 7-15 days. The temperature rise and ventilation and oxygenation speed up the evaporation of the moisture of the material, and the exhaust gas and water vapor are discharged through the deodorizer through the deodorization system, thereby reducing the volume of the material and achieving the management of compost manure.

 

3) Automatic feeding part

 

The materials in the fermentation chamber are stirred by the main shaft and fall layer by layer under the action of gravity. After fermentation, they are discharged as organic fertilizer raw materials, with a moisture content of less than 40%, to realize the resource utilization of organic waste. After the organic fertilizer raw materials are released and stored in the organic fertilizer warehouse for 20-30 days, the temperature will decrease more steadily, and you can use animal waste as fertilizer.

Advantages of chicken manure high temperature aerobic fermentation tank equipment

 

1. Using the composting techniques for poultry waste of biological bacteria, the operating cost is low;

 

2. Main body thermal insulation design, auxiliary heating to ensure normal operation of equipment in low temperature environment;

 

3. The exhaust gas is collected and deodorized in a centralized manner to achieve gas emission standards without secondary pollution;

 

4. The inner layer of the equipment is made of 304 stainless steel, which reduces corrosion and has a long service life;

 

5. Small footprint and high degree of automation, one person can control the entire fermentation process;

 

6. Factory operation, the number of equipment can be determined according to the processing capacity.

 

7. The treated materials are used as organic fertilizer raw materials to realize the resource utilization of organic wastes.
