Dynamic fermentation mode of organic fertilizer production line
Dynamic fermentation mode of organic fertilizer production line
1. Technological process of dynamic fermentation mode
Feces, bacteria, a small amount of straw (or not) - fermentation tank - automatic mixer walking on the fermentation tank mixing - granulator - screening machine - transparent greenhouse short-time drying - packaging machine - storage
Feces, bacteria, a small amount of straw (or not) - fermentation tank - automatic mixer walking on the fermentation tank - organic-inorganic mixer - granulator - screening machine - transparent greenhouse (short time drying) - packaging machine (weighing and bagging)
Note: the trough type automatic mixer organic fertilizer production machine can automatically walk along the fermentation tank, ventilate and send oxygen to the fermentation materials in the tank, and adjust the water content. This process does not need to add a large amount of straw (only a small amount of straw is added when the seasonal feces are thin). After one year of use, the amount of bacteria can be reduced, and the organic fertilizer produced is harmless with low cost. According to the fecal treatment capacity and production needs, the span of automatic mixer can be 2-3.5 meters, the length of fermentation tank can be extended by 20-30 meters, or 3-5 fermentation tanks can be built at the same time (only one tank changing car needs to be added).
The special granulator for organic fertilizer can granulate the fermented material with 40% moisture in spherical form. The finished product rate of the granules is more than 70% and the hardness is moderate. Small scale production can be carried out by drying and bagging.
