 The fermentation process of organic compost

1.    Medium temperature stage.

 In the initial stage of compost production, microorganisms in compost are mainly of medium temperature and aerobic type, They start composting fermentation process, can decompose organic matter (such as a simple sugar, starch, protein, etc.) under aerobic conditions, and produce a significant amount of heat, constantly improve the composting temperature, has risen from about 20 to 40 . The double-screws turning machine is suitable for aerobic fermentation

2.    High temperature stage
  With the increase of temperature, thermophilic microbial gradually replace the medium temperature microbial and play a leading role, generally within a few days, the temperature is more than 50 , and entered the stage of high temperature. At high temperatures, thermophilic actinomyce and fungi become the main species. They decompose complex organic substances (such as cellulose, hemicellulose, pectin substances) in the compost, accumulate the heat ,the compost temperature rise to 60-70 , and even can be as high as 80 . And most of the thermophilic microorganisms will be dead or to enter a dormant state, it has very important effect to accelerate the composting process.

3.   Cooling stage

  When the high-temperature stage lasts for a certain period of time, most of the cellulose, hemicellulose and pectin substances have been decomposed. Microbial activity becomes weakened and the temperature begins to drop. When the temperature drops to below 40 , medium temperature microorganisms are the dominant species. At this time, you can turn over the compost heap, mix the stacking materials evenly, so that it will produce a second heat to promote the compost decomposing.

 

4.   Maturation and preserving fertilizer 

  When the compost was decomposed thoroughly, its volume begins to decrease, and the heap temperature drops to a little higher than the air temperature. At this time, compost should be pressed tightly, resulting in an anaerobic state, which will weaken the mineralization of organic matters, so as to facilitate the maintenance of fertilizer.

In short, the fermentation process of organic compost is actually the process of metabolism and reproduction of various microorganisms. Which is the decomposed process of organic matter.

Notice:

    In the process of composting, turn over the heap is necessary. Hydraylic type groove turning machine is the better choice, The fermenting and dumping of organic wastes, such as livestock manure, sludge garbage, they are widely used in the fermentation and removal of water in organic fertilizer plant, compound fertilizer plant, sludge waste plant, gardening farm and BIS mushroom plant. Generally, when the heap temperature crosses the peak and begins to cool down, turning over the heap can make the inner and outer layer decompose at different temperatures and remix evenly. If the humidity is insufficient, some water can be added to promote even compost maturation.
