There are many kinds of organic fertilizer products, among which bio organic fertilizer is a relatively high-grade fertilizer. The production process of bio organic fertilizer with livestock manure is slightly different from that of other fertilizers. The purpose of this process is to protect the microbial bacteria in the process of fertilizer production. The following is a brief description of the production process of this fertilizer with various raw materials.
Production technology of chicken manure organic fertilizer
The moisture content of chicken manure is high, and the processing flow of chicken manure fertilizer production line is applicable to other animal manure treatment. In the first stage of fermentation, excessive moisture content of the material used for fermentation is not feasible, which requires dehydration treatment. Chicken manure dehydrator can be used to dry and wet separation of solid feces, and then fermented and decomposed.
Production process of biogas residue organic fertilizer
Biogas residue is the residue remaining after the production of biogas from livestock and poultry manure, and is a good raw material for the production of microbial organic fertilizer. Although anaerobic fermentation has been carried out, in order to achieve complete harmlessness, it is best to continue to enter the tank for aerobic fermentation. The biogas residue extracted from the biogas digester has a high moisture content, which is the same as chicken manure. It needs to be dehydrated and then fermented.
The main link of organic fertilizer production line is the fermentation of organic fertilizer raw materials, and the subsequent processes are deep processing and commercialization. For example, the fermented materials can be made into powder organic fertilizer products, or can be processed into granular fertilizer products by rotary drum granulator. Different fertilizer products have different properties and use different fertilizer pelleting equipment. Fertilizer granulator machine price is low, and the effect of organic matter granulation is good. It is widely used in organic fertilizer granulation technology.
Microbial organic fertilizer products are added with microbial bacteria on the basis of ordinary organic fertilizers. Because these bacteria have a limit on the survival temperature, when producing granular biological fertilizers, in order to prevent them from being killed by high temperature in the dryer, Will use low temperature drying mode. Or adding bacteria in the coating machine stage, these are better solutions.
