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.
