The organic fertilizer production process is mainly to ferment and decompose the animal dung organic wastes such as cow dung, sheep dung, pig dung, chicken dung, sludge, rice straw, corn stalks, etc. In the granulator, the finished granules are transported by the belt to the finished product silo, and the process of packaging and warehousing after drying at low temperature and large air volume (≤65°C) by the dryer, cooling, screening and coating.
How to deal with materials before organic fertilizer production?
(1) Municipal waste should be selected, and debris such as broken glass, stones, tiles, and plastics should be selected, especially to prevent the entry of heavy metals and toxic organic and inorganic substances.
(2) In principle, various accumulation materials should be crushed, and the contact area is conducive to decomposition, but it will consume more energy and manpower, and it is difficult to promote. It is generally best to cut various bulk materials into 2-5 inches.
(3) For hard and waxy materials, such as corn and sorghum, the water absorption is low, soak the material powder with sewage or 2 lime water, destroy the wax layer on the surface of the straw, and use water absorption to promote corrosion.
(4) Aquatic weeds, due to the high water content, should be refrigerated and dried before accumulation.
