Applicable conditions for fermentation in the third fermentor
Use sawdust, sawdust and other moisture to adjust materials, and the moisture content is generally controlled at 50-75%. Air: the upper part, lower part and mixing blade of fermentation tank shall be evenly ventilated. Temperature: 50-70 ° C is the ideal temperature for aerobic microorganism propagation, and the operating temperature is usually controlled at 60 . C or so, the temperature of the material is reduced to below 50 ° C after it is decomposed. PH value, C, N ratio: PH value 6-8.5 (PH value, C, N ratio of ordinary organic wastes are suitable for fermentation tank The raw materials treated with lime and sulfuric acid are not suitable for fermentation). High temperature fermentation strain: it can survive and reproduce at - 25 ° C - 80 ° C, and the beneficial bacteria formed can kill Harmful bacteria. PLC automatic control, operating power is about 21Kw/h, about 500Kw/d.
