Ferment Organic Mixture in the Tank within 55-65% moisture
Before fermentation, you need to match the fertilizer to a certain proportion, so that the fermented fertilizer can have better fertilizer efficiency.Therefore, there must be a mixing link in the early stage.You need to add the following things:
75% moisture content of feces or organic waste
40% moisture content of the reflux material
10% moisture content of the conditioning base
You can adjust moisture content, C: N, air permeability to achieve fermentation conditions. If the moisture content of the raw material is 55-65%, you can directly put into the tank for fermentation.
3 stages of fermentation in an organic fertilizer fermentation tank
During fermentation process your material goes through three stages:a rapid heating stage, a high temperature stage, and a cooling stage.
Your material enters the fermentation tank and decomposes rapidly within 24-48 hours under the action of aerobic bacteria. The released heat makes the temperature of the material rise rapidly, the temperature is generally 50~65°C, and the highest can reach 70°C.
Through the air supply and aeration system, oxygen is evenly sent to the fermentation tank to meet the oxygen demand of the fermentation process. Your material is fully fermented and decomposed, and the high temperature stage maintain for 5-7 days.
When the decomposition rate drops slowly, the temperature gradually drops below 50 degrees. The whole fermentation process lasts 7-15 days.
Elevation of temperature and oxygenation by ventilating accelerate the evaporation of moisture in the material. Through the deodorization system, the waste gas and water vapor discharge through the deodorizer after treatment, so as to reduce the volume of the material and achieve the purpose of reducing, stabilizing and harmless the material.
