In vessel composter is a kind of totally-closed, vertical type compost fermentation equipment, being an air-clean anaerobic fermentation system. It is widely used for processing organic wastes into organic fertilizer, suitable for various organic waste, such as: animal manure (pig manure, chicken manure, cow dung), agricultural waste, livestock waste, kitchen waste, municipal sludge, industrial waste, mushroom residue, crop straw etc.
Compared to windrow composting method, if there is few available land for composting project, In vessel composter is a better choice to realize the utilization of waste resources for the livestock breeding.medium and large farms, circular agriculture, ecological agriculture etc.
In Vessel Composting Process
In vessel composter adopts the microbial aerobic fermentation that microorganisms can make full use of organic matter and residual protein in animal manure, and reproduce rapidly under certain conditions of temperature, humidity and sufficient oxygen. During the reproductive processes, microorganisms consume the organic matter, protein and oxygen of the manure, thus metabolize into ammonia, C02 and water vapor Meanwhile, large amount of heat is released that can raise the temperature of tank. It is mainly composed of the fermentation chamber, hoisting system, high-pressure air supply system, drive system, hydraulic power system, deodorization system, discharging system and automatic control system. Adopt PLC programmed control, the process of feeding, fermentation, temperature control and discharging is automatically completed.
The process flow mainly includes the following steps : Mixing-Conditioning-Feeding-Fermentation-Discharging
