Selection of organic raw materials and processing details of fertilizer production line


Organic fertilizer is a kind of fertilizer commonly used in agriculture, which has a very high efficiency. It is made of livestock manure fermentation and drum granulation. So how to choose the raw materials of organic fertilizer? What details should be paid attention to in the processing of organic fertilizer?

No matter what the raw materials are, the general principles for selecting organic fertilizer raw materials are as follows.
(a) Wide sources of raw materials and stable supply;
(b) The raw material has low water content;
(c) Suitable nitrogen, phosphorus, potassium and organic nutrients;
(d) Perishable;
(e) Low cost or low price.

Processing details of fertilizer production line

1. In the early stage of organic fertilizer production line, compost fermentation is the main process. In addition to the main raw material animal manure, organic materials such as straw powder, mushroom residue, peanut shell powder, rice husk, sawdust and other organic materials should be added to the materials to adjust the aeration. If rice husk and sawdust are added, the fermentation time should be prolonged because of its high cellulose lignin.

2. PH can also affect the efficiency of organic fertilizer fermentation. The pH of organic fertilizer fermentation is neutral or weak alkaline. We can use quicklime to adjust the pH of fermentation products to control the fermentation of compost.

3. Generally, after 72 hours of composting, the temperature will rise to 50-60 ℃, and the fourth day can reach above 65 ℃. Under this high temperature, it is suggested to start loosening treatment and use compost tipper to treat materials. In general, there will be 2-3 times of high temperature above 65 ℃ in the fermentation process, and the fermentation can be completed after 2-3 times of overturning, so that the materials can be completely deodorized, fermented and decomposed, sterilized and killed insects.
