How much investment is needed to build a small organic fertilizer processing plant?
The main raw materials of organic fertilizer production process are animal manure (pig manure, chicken manure, cow manure, sheep manure, etc.), domestic waste, straw, mushroom residue, etc. The cost is 0 yuan.
The organic fertilizer production process uses microbial fermentation agent as the fermentation agent, which is mixed and stacked for a certain period of time to produce bio organic fertilizer (green micro organic fertilizer fermentation bacteria, 1 kg can ferment 2-3 tons of organic fertilizer, with less addition, high cost performance, easy to use, good effect, recommended choice). The cost is about 10 yuan / ton.
There are two steps to process commercial organic fertilizer in the organic fertilizer production line: early fermentation and treatment part and deep processing granulation part. Organic fertilizer equipment needs fermentation compost windrow turner, crusher, mixer, organic fertilizer granulator, dryer, cooler, screening machine, coating machine, packaging machine, conveyor and other equipment.Organic fertilizer production plant cost about 250000 yuan.
The process flow of organic fertilizer machine production line can be divided into raw material pretreatment, aerobic fermentation and fertilizer granulation. The pretreatment of raw materials includes solid-liquid separation, excipient crushing and adjustment of water content, carbon nitrogen ratio and pH value of raw materials. The process of aerobic fermentation includes throwing and ventilation, which can supplement oxygen, control temperature, emit water and recover porosity. Fertilizer granulation processing is a systematic project. Around the core of granulation (organic fertilizer granulator), there are crushing, batching, mixing and other processes before, and drying, screening, cooling and other processes.
