Fermentation aging process of small scale chicken manure organic fertilizer production line
Chicken manure is one of the ways to treat chicken manure in chicken breeding. Chicken manure will be sold to organic fertilizer plant, which will be processed into organic fertilizer for the second time, and then sold to farmers to grow crops. The main components and price of organic fertilizer plant were discussed in the front. Today, we will introduce the main process of small chicken manure organic fertilizer production line
(1) Raw material pretreatment of chicken manure organic fertilizer production machine
Objective: the purpose of raw material pretreatment is to adjust the ratio of water and carbon to nitrogen, and to add bacteria to promote the rapid fermentation process
Process: the main organic solid waste materials and auxiliary materials are mixed according to the proportion of ingredients, and microbial strains are added to promote the rapid fermentation process. The mixed materials are transported to the fermentation tank by forklift
(2) Primary fermentation
Objective: the purpose of aerobic composting of chicken manure organic fertilizer production line is to reduce the volatile matter and odor in the waste, kill parasite eggs and pathogenic microorganisms, and achieve the goal of harmless. In addition, through composting fermentation treatment, the moisture content of organic materials is reduced, the organic materials are decomposed and mineralized, and the nutrients such as N, P, K are released. At the same time, the properties of organic materials become loose and dispersed
Process: on the one hand, oxygen is supplied through aerobic fermentation to avoid the formation of anaerobic environment and volatilization of water during composting; The composting cycle is 15 days, and the composting temperature can rise to 60-70 ℃, After fermentation, the moisture content is greatly reduced (generally to about 40%) and transported to the Aging Workshop by forklift
(3) Aging
Objective: the organic solid waste of chicken manure organic fertilizer production line after one-time composting fermentation has not yet reached complete maturity, so the second fermentation needs to be continued. The purpose of aging is to further decompose, stabilize and dry the remaining macromolecular organic matter in the organic matter, so as to meet the requirements of subsequent composting process
Process: the production line of chicken manure organic fertilizer adopts trough process for aging and fermentation. During the aging process, the temperature of the compost will gradually drop. When it is stable below 40 ℃, the compost will be decomposed to form humus. The aging cycle is about 10-20 days, which can be adjusted according to the characteristics of fertilizer processing materials
