Moisture is an important indicator in the production of organic fertilizer. Therefore, pig manure is more suitable for producing organic fertilizer by dry manure cleaning. The first step of composting fermentation is to adjust the moisture. The most suitable moisture is 50%-60%. Too dry or too wet will affect the aerobic fermentation process. In this process, a pig manure dehydrator is needed to treat the moisture. In addition to the dehydrator, other
pig manure fertilizer machines are required to process pig manure into organic fertilizer.
After the feces are collected, composting fermentation will be carried out. If a
pig manure fertilizer machine is used in this link, the production capacity will be greatly improved. First, by adding high-carbon and low-water auxiliary materials, the moisture and C/N ratio should be adjusted to the appropriate ratio. Then, the fermentation method is selected according to the scale and site of the pig farm. The complete composting fermentation includes three stages: heating period, high temperature period, and cooling and maturation period. In general, in simple pig farms, the high temperature period is mainly carried out, and insect eggs are killed by aerobic fermentation to achieve the purpose of harmlessness. Aerobic fermentation requires continuous turning of the compost. Pig farms with conditions can use compost turning machines and ventilation equipment. This process usually takes 20 days.
If commercial organic fertilizer is produced, nutrients and moisture need to be adjusted to meet industry standards. If it is difficult to meet the standards using only pig manure as raw material, some additional raw materials such as charcoal ash are generally required. Or add different proportions of nitrogen, phosphorus and potassium after fermentation. It is understood that functional bacteria can also be added to continue fermentation to make various functional organic fertilizers. The continuous process requires different types of
pig manure fertilizer machines. If you are interested in this, please contact Huaqiang Heavy Industry.
