Pig farm manure fermentation technology

The biggest headache of pig farms is the problem of fecal treatment, because composting not only occupies space, but also easy to produce peculiar smell. Under the pressure of environmental protection, pig manure treatment is a big problem. As long as the feces are handled properly, it can not only solve the environmental problems of pig farms, but also bring additional income. Now the market price of organic fertilizer is very high. 

Raw materials are livestock excreta, straw and other crop wastes. Organic fertilizer fermentation equipment manufacturers share pig manure fermentation technology and carry out biological fertilizer projects.

Technology of pig manure fermentation organic fertilizer

1. Add fermentation bacteria: livestock manure 60%, food bacterial residue 20%, straw and other materials with low water content (reduce the water content to 50%, which is the appropriate water content for fermentation), and 1% bacterial starter. The purpose of adding bactericide is to increase the heating rate, control the fermentation temperature at 65 ℃ ~ 70 ℃, eliminate peculiar smell and sterilization in the fermentation process, speed up the fermentation speed and shorten the fermentation time to about 15 ~ 20 days

Precautions for fermentation process: stir with compost dumper every 2 days. In order to increase the oxygen content, the compost needs to be turned constantly; At the same time, the fermentation strains need to contact the materials more evenly to improve the maturity and speed up the fermentation maturation process.

2. Crushing after fermentation and ripening: because some decomposition products are too large for fertilization, they need to be crushed with a semi wet material crusher to prepare for the next organic fertilizer granulation (the smaller the crushed particles are, the easier it is to granulation). The crushed and stirred materials are powdery, which is not conducive to mechanical fertilization.

At present, many organic fertilizers on the market are fermented with animal manure, crop straw, pressed cake or beer residue and monosodium glutamate residue. In the fermentation of organic fertilizer, the nutrient content of chicken manure is the highest, followed by pig manure. 

Now it is fed with concentrate, so the nutrient content and organic matter content of pig manure are relatively high (the nutrient content of pig manure raised by farmers is relatively low), which is suitable for organic fertilizer fermentation. According to many experimental results, the effect of pig manure organic fertilizer is similar to that of chicken manure fermentation

Therefore, the market prospect of pig manure fermentation as organic fertilizer is very good. SX fertilizer equipment manufacturer provides customers with organic fertilizer equipment and NPK fertilizer production line to help complete fertilizer manufacturing and processing.
