The fermentation method of the production line of 50,000 tons of straw manure and organic fertilizer is as follows:  
1. The auxiliary materials such as cow dung, straw and straw, and fermentation agents are stacked in the fermentation site in a certain proportion.  
2. When the fermentation temperature of compost rises, it can be turned over. When the fermentation temperature is about to reach 70 degrees, it is necessary to use the turning machine to turn over the pile, and turn over the pile every once in a while.  
3. When the temperature of compost is reduced, the material is loose, the odor is slightly ammonia, and the white mycelium is produced in the pile, it indicates that the organic fertilizer has been fermented and mature, and the next process can be carried out.  
4. Use forklift truck to transport organic fertilizer to the production workshop, through a series of production processes, produce granular organic fertilizer, and packaging into bags.  
 
Annual output of 50,000 tons of straw livestock manure organic fertilizer production line investment?  
1. Powdery annual output of 50,000 tons of straw manure organic fertilizer production line equipped with equipment:  
Forklift feeder + compost turner machine + belt conveyor + new vertical grinder + rotary screening machine + powdery packaging machine, complete set of equipment needs to invest about 130-200,000 yuan.  
2. Annual output of 50,000 tons of straw manure organic fertilizer production line:  
Compost turner machine + crushing machine + mixing maching + batching machine + granulation machine + drying machine+ cooling machine + screening machine + coating machine + packaging machine, investment of about 220-350,000 yuan (the price is mainly different from the granulation process, organic fertilizer granulator, dryer, cooling machine and coating machine, can be purchased according to their own needs).  
 
In Tongda Heavy Industry, we will design a reasonable annual output of 50,000 tons of straw livestock and poultry manure organic fertilizer production line plan for users, to ensure a lower price investment, faster cost recovery later, higher economic value.
