There are many kinds of organic fertilizer products, among which microbial organic fertilizer is a relatively high-grade fertilizer. The microbial organic fertilizer production process using livestock manure is also slightly different from that of other fertilizers. The purpose is to protect the microbial bacteria in the fertilizer production process. Here, the paper briefly describes the production process of various fertilizers for the production of such fertilizers.

Chicken manure organic fertilizer production process
Chicken manure has high moisture content, and its production process is applicable to other poultry manure treatments. In the first stage of fermentation, it is not feasible to use too much moisture content to ferment, which requires dehydration. The solid manure can be separated by dry and wet separation using a chicken manure dehydrator, and then fermented and decomposed.

Cow manure organic fertilizer production process
Cow dung is relatively suitable for moisture content. Of course, if some cow dung is mixed with urine, it needs to be dehydrated first. Due to the different foods to be fed, the digestibility is also different. The cow dung contains more fiber components, so that the fermentation cycle can be slightly longer during fermentation, making it completely decomposed.

Biogas residue organic fertilizer production process
Biogas residue is the residue remaining after the production of biogas from livestock manure, and is a good raw material for the production of microbial organic fertilizer. Although anaerobic fermentation has been carried out, in order to completely achieve harmlessness, it is preferable to continue the tank to carry out aerobic fermentation. The moisture content of the biogas residue extracted from the biogas tank is high, which is the same as the chicken manure, and needs to be dehydrated and then fermented.

The main link in the organic fertilizer production process is the fermentation of organic fertilizer raw materials. The subsequent processes are all deep-processing and commercialized. For example, the fermented materials can be made into powder organic fertilizer products, or can be processed into fertilizer pellets using organic fertilizer granulator machine.

Microbial organic fertilizer products add microbial bacteria on the basis of common organic fertilizers. Because these strains have a limit on the temperature of survival, when producing granular bio-fertilizers, in order to avoid being killed by high temperature in the dryer, A low temperature drying mode will be used. Or adding bacteria at the stage of the coater is a better solution.
