Fruit is obvious, and microbe inoculation amount is on the low side.And because the particle diameter of decomposed material is smaller, the hole between fresh material is plugged, is made
Into sluggish in air circulation, anoxic even anaerobic environment is formed, is unfavorable for aerobic fermentation.
Experiment 1 and experiment 5 difference be：The fresh material of experiment 5 does not identify by front end classification garbage can, is mixed into
Many non-rubbishes from cooking, material heating rate are decreased obviously, and the content of organic matter is low, and its degradation rate is relatively low, final material fermentation
Not exclusively, decomposed degree is low.
Experiment 1 and experiment 6 difference be：Experiment 6 employs the circular fermentation cylinder in embodiment 3, and originally material heating is just
Often, when a large amount of microbial degradation organic matters, substantial amounts of heat is generated.It is changed into after moisture absorption among material heat
Vapor evaporation rises, and is partly pulled out fermentation cylinder, and the steam for having little time to take away up runs into that to be condensed into liquid behind cylinder top attached
At top, surface of material is fallen to again after pooling drop afterwards.The specific heat capacity of water is very big, and a large amount of condensed waters absorb heat
Amount, reduces the temperature of material in itself, has slowed down the process of whole fermentation, finally have impact on rotten degree and water after material fermentation
Divide and remove.
