Bio-organic fertilizer production process
2019-11-13
Biofertilizer project is made of organic waste such as crop straw (such as straw, wheat straw, etc.), edible mushroom nutrient residue, inorganic minerals (salt such as salt mine and phosphate rock), animal manure (chicken manure, cow dung), etc. A certain proportion of the ratio, and then mixed with a certain amount of microbial flora, accumulation, high temperature fermentation, decomposition, sterilization, amino acid, nitrogen, phosphorus, potassium and other crops need nutrients for nutrients for crops to absorb.
In simple terms, it is divided into the following steps:
Pre-treatment: After the compost material is transported to the yard, it is weighed by the scale, sent to the mixing and agitating device, mixed with the production and living organic wastewater in the plant, and the compound bacteria are added, and the fertilizer moisture and carbon-nitrogen ratio are coarsely adjusted according to the raw material composition. After mixing, proceed to the next step.
One-time fermentation: the mixed raw materials are sent to a fermentation tank by a loader, piled up into a fermenting pile, and a fan is used to forcibly ventilate from the bottom of the fermentation tank to supply oxygen, and at the same time, the compost turner machine is used for turning over 2 days. And add water (mainly in the factory production, living organic wastewater mainly) and nutrients, control the fermentation temperature in 50 C ~ 65C, aerobic fermentation, the first fermentation cycle of this project is 8 days, a pool of raw materials a pool every day After the semi-finished product, the fermented semi-finished product is discharged, ready to enter the next process.
Post-treatment: The finished compost product is further sieved, and the sieved materials are separately treated according to the high and low moisture content. After the granules are granulated, they are sent to a dryer heated by biogas in the biogas digester, dried, and the medium and trace elements are added in proportion, and then mixed and mixed to form a finished product, which is packaged and stored in the bio-organic fertilizer production. The process is sold. The sieve material is returned to the pulverization process for reuse.
