Organic fertilizer fermentation tank, also known as intelligent high-temperature aerobic fermentation tank, is the main component of reactor type composting fermentation system. According to the different reflection containers, they can be divided into silo type, tower type, drum type, mixing box type, and circular mixing bed. There are six types of tunnel type and tunnel kiln type. Its working principle is to mix livestock manure, kitchen waste, domestic sludge and other wastes in a certain proportion and send them to the Organic fertilizer fermentation tank after the water content meets the design requirements. During this period, intelligent high-temperature aerobic treatment equipment is controlled through ventilation, oxygenation, and stirring to reach the temperature of the fermentation process.
Fermentation steps of Manure fermentation tank
Take the fermentation of chicken manure as an example. The chicken manure is decomposed to produce biological Manure. The steps are as follows: put an appropriate amount of rice bran, straw powder, mixed microbial agent composed of bacteria, subtilis spores, thermophilic heterotrophic Ammoxidation and thermophilic spores, and chicken manure in the fermentation tank of Manure, mix evenly and adjust its water content to about 45%; Then heat the material and let it ripen at 50-55 ℃ for 20-25 hours. The second step is to mix an appropriate amount of microbial inoculants and rice bran evenly, add them to the material after fermentation, stir evenly, and ripen at 37~40 ℃ for 25~30 hours to complete the ripening.
