Composting process of livestock and poultry manure
The composting process of livestock manure organic fertilizer production line includes static composting, strip stack composting, trough composting and reactor composting.

1. Static stacking

Generally refers to natural fermentation in traditional agricultural production. An aeration system can be arranged at the bottom of the reactor, which has the characteristics of low operating cost, long fermentation cycle, large area, unstable product quality, etc. It is used in the treatment of dispersed organic waste in rural areas More.

2. Strip stack compost

Organic fertilizer production stacks organic waste materials into a stack, and uses a self-propelled stacker to toss the stack during the fermentation process, which promotes the rapid fermentation of organic waste. A simple composting technology with investment Low cost, large area, poor operating environment, uncontrollable odor, fermentation is easily affected by environmental temperature, etc. It is mainly suitable for waste treatment in small and medium-sized farms.

3. Trough compost

Generally, it is carried out in a closed fermentation plant, and it can also be carried out in an old abandoned house. By stacking organic waste raw materials at the front of the fermentation tank, using a tank-type turning machine to move the material, and arranging an aeration system at the bottom of the fermentation tank, the material To achieve rapid rot. Trough compost has the characteristics of large processing capacity, short fermentation cycle, high degree of automation, odor can be collected and processed, and high cost of civil engineering investment. It is suitable for centralized treatment of waste on large-scale farms.

4. Reactor compost

It refers to placing organic waste in an integrated composting reactor to achieve rapid fermentation and decay of waste through aeration, stirring and other functions. It has the characteristics of small processing capacity, short fermentation cycle, good processing effect, high one-time investment cost, etc., mainly Suitable for waste disposal in small farms.

Generally, compost products can be used as the basic raw materials of organic fertilizer products. If compost products are mainly used on the farm itself, they can be used after they meet the requirements of harmlessness and complete decay; if compost products are used to process commercial organic fertilizer products, they should be Organic fertilizer product standards require further processing and production.
