Fermentation is an important part of organic fertilizer production, and the fermentation cycle includes primary fermentation and secondary fermentation. Generally speaking, livestock manure, which decomposes easily, decomposes faster under proper composting conditions and more slowly under poorer conditions. In actual production, the fermentation cycle of compost is about 1-2 months. If the composting conditions are good, and measures are taken to promote the fermentation of the compost during the composting process, the time required for composting can be appropriately shortened.
During the different fermentation stages, the decomposition of microorganisms is very active in a fermentation. Since the heat from fermentation raises the temperature rapidly and requires a lot of oxygen, the required turnover frequency is also relatively high. In the secondary fermentation, the decomposition reaction is slowed down and less heat is generated, so the frequency of turnover can also be reduced.
How to improve the efficiency of organic fertilizer fermentation? The organic fertilizer production equipment compost turning machine can help the manure to be turned over during the fermentation process for aerobic fermentation. Listed below are several common fermentation tumblers.
1. Crawler-type compost turning machine, strip-type turner has the advantages of low fuel consumption, flexible action, strong turning force, and convenient driving, but it has disadvantages such as low composting depth, large floor space, and poor plant environment.
2. The trough type turning machine, also known as the rail type turning machine, is to lay a track on the wall of the long fermentation tank. The flipper can move back and forth on the track on the fermenter, while the rotary motion of the throwing knife can flip the material, break it and throw it backwards.
3. The transmission mode of the chain turning and throwing machine is chain transmission, so the resistance of turning and throwing is small, saving electricity and energy. The material grabbed during flipping and throwing is slowly lowered after moving on the pallet. The high gap where the material is scattered makes the water fully volatilize, fully contact with the air, and realize the full turnover and throwing of the material in the fermenter through the horizontal and vertical composite motion.
