Earthworm is a kind of Invertebrate which can be used as high protein feed additive. In the process of breeding earthworms, earthworms can digest garbage, straw and other organic substances, and excrete Vermicompost mixed with soil. Vermicompost is a good decomposed Organic fertilizer, as well as a soil with granular structure, which can promote the growth and development of crops. Cultivating a certain number of earthworms in farmland can have a better effect on soil improvement and fertilization..jpg)
Early fermentation part of Vermicompost Organic fertilizer production line: 3m wide × A 50 meter fermentation tank can also have multiple tanks in one machine, and then the raw materials are stacked in the tank. 1 kilogram of composting agent is mixed with 20 kilograms of water, and mixed in the raw material pile. 1 kilogram of composting agent can ferment 1 ton of raw materials. According to the comparison of raw materials, the fermentation cycle is 7-10 days at a temperature of around 0C ° C. Once every 2 days, it can be completely decomposed. The raw materials of Organic fertilizer are fermented and decomposed, crushed by a semi wet material grinder, screened by a roller screen, screened out the coarse materials, and then fermented. The fine materials can be granulated, with a more beautiful appearance and a higher rate of granulation. After fermentation, the materials (water content is 35%) are mixed in the mixer, and then dried in the Organic fertilizer granulator, then dried in the Organic fertilizer dryer, cooled in the cooler, screened in the drum screening machine. Unqualified products are returned to the mixer. Qualified products can be coated with calcium, magnesium, sulfur and other trace elements in the coating machine, and can pass through the bin and packaging machine.
Among them, the reasonable matching of raw material fineness is crucial to the process flow of Organic fertilizer production line. The higher the fineness of the raw material, the better the viscosity, and the higher the surface smoothness of the particles after granulation. However, in the production process, the use of ultra high proportion and high fineness materials is prone to problems such as oversized particles and irregular particles due to poor adhesion.
