The granulation process of a complete set of earthworm manure organic fertilizer processing equipment

The humic acid in earthworm manure is different from that in general organic fertilizers because earthworms regularly digest and mix many organic nutrients to transform them into water-soluble substances, which are easily absorbed by plants. Planting crops with earthworm manure not only has the effects of drought resistance and fertilizer retention, promoting roots and seedlings, and not reducing production, but also significantly improves the quality of crops and restores their natural flavor. It can also be used as an additive for poultry and livestock feed, making it convenient, clean, and safe to use.

The complete set of earthworm manure organic fertilizer processing equipment pre-treatment: After the compost raw materials are transported to the yard, weighed by a scale, sent to a mixing and stirring device, mixed with organic wastewater from production and domestic use in the factory, added with composite bacteria, and roughly adjusted the moisture and carbon nitrogen ratio of the compost according to the raw material composition. After mixing, they enter the next process.

The complete set of earthworm manure organic fertilizer processing equipment undergoes one-time fermentation: the mixed raw materials are fed into a fermentation tank using a loader and stacked into a fermentation pile. A fan is used to forcibly ventilate from the bottom of the fermentation tank upwards for oxygen supply. At the same time, the pile is turned over for about 2 days and supplemented with water (mainly organic wastewater from production and domestic use) and nutrients. The fermentation temperature is controlled between 500C and 650C for aerobic fermentation. The one-time fermentation cycle of this project is 8 days, Every day, one pool of raw materials is fed out and one pool of semi-finished products is produced. After the fermented semi-finished products are discharged, they are ready to enter the next process.

Complete set of earthworm manure organic fertilizer processing equipment for post-processing: Further screening of the compost product, and treatment of the screened material according to the moisture content. After sieving and granulating, the material is sent to a dryer heated by biogas in the biogas digester for drying. After adding medium and trace elements in proportion, it is stirred and mixed to make a finished product, which is then packaged and stored for sale. The screened material is returned to the crushing process for reuse.
