How to build a simple organic fertilizer production line in a chicken farm

Chicken dung is combined with corncob to produce organic fertilizer. The chicken dung and corncob are fully mixed with a forklift. The corncob absorbs the water in the chicken dung, and the water content of chicken dung is reduced. After the corncob absorbs water, it and chicken dung together produce heat fermentation, and produce organic fertilizer after sterilization and ripening. Due to the addition of corncob, the content of organic matter in organic fertilizer reached the required standard, while the content of heavy metals in chicken manure was also diluted and decreased.
Raw materials (taking the production of 1 ton of organic fertilizer as an example): 1.8 tons of human manure or livestock manure, 0.3 tons of straw powder or leaf powder, 2.5 kg of corn flour, and 1 kg of bacterial rapid fermentation agent. Human excrement, livestock and poultry excrement+leaves or straw powder+corn flour+bacteria species→mixing → composting → drying. First, control the water content of the mixed raw materials to about 40% – 50%, then mix the bacteria with the water surface, spread it on the surface of the mixed fertilizer, and manually and evenly put the raw materials into the mixer for crushing and mixing. The water content of fertilizer should be controlled when it is mixed and crushed. Generally, the water content should not exceed 40-45%. Too much or too little water will affect the fermentation quality, so it is appropriate to squeeze the fertilizer into the dough with your hands, see the water in your hands, but do not drop it, and drop it on the ground. Stir evenly, thoroughly and fluffy without leaving raw blocks. The mixed ingredients are piled into strips with a width of 1.5-2 meters and a height of 0.3-0.4 meters, and covered with straw curtains or sacks for aerobic fermentation. Generally, the temperature of stacking can rise to 50 ° C within 24 hours and 60-70 ° C within 48 hours. During fermentation, such high temperature can kill all pathogenic bacteria, insect eggs, grass seeds, etc. According to the fertilizer making test, it generally takes 6 days to compost in spring, summer and autumn, and 7 days in winter. When the white hypha grows on the top and bottom of the fertilizer, that is, it is all ripe, and it can be dried and screened slightly.

3 Chicken dung contains a large number of harmful microorganisms, which must not be directly applied, and must be subject to deep high-temperature fermentation. There are two main purposes of certain fermentation. One is to kill harmful bacteria, and the other is to organicize the under-digested substances to increase the content of actual organic matter. Fermentation is mainly carried out in the fermentation tank, that is, chicken manure is piled up in the fermentation tank. It is best to add appropriate amount of fermentation bacteria at the same time, and then use agricultural plastic film to cover the fermentation. The fermentation time is usually 10-20 days. 3.2 The chicken dung after deep fermentation shall be dried and crushed. The shredded chicken manure can be directly applied, but it is only called traditional farmyard manure, not commercial organic fertilizer.

There are two types of equipment for chicken manureorganic fertilizer production line: granular production line and powder production line. The prices of these two kinds of equipment are different. The prices of the two organic fertilizers sold on the market are also different. Process flow of commercialorganic fertilizer production line: crushing ->mixing ->granulation ->drying ->cooling ->coating ->screening ->metering sealing ->warehousing of finished products. Finally, our common commercial organic fertilizer will be produced.
