Organic fertilizer is a fertilizer commonly used in agriculture, and the efficiency is very high. It is made from fermentation of livestock and poultry manure and granulation of drums. 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 material, the general principles for choosing organic fertilizer raw materials are as follows.
(a) The source of raw materials is extensive and the supply is stable;
(b) Low water content of raw materials;
(c) Appropriate nitrogen, phosphorus, potassium and organic nutrients;
(d) Perishable;
(e) Low or low price.
Fertilizer production line processing details
1. The early stage of the organic fertilizer production line is mainly compost fermentation. In addition to the main raw material animal manure, organic materials such as straw powder, shiitake mushroom residue, peanut shell powder, rice husk, sawdust and other organic materials should be added to adjust the aeration. If rice husks and sawdust are added, the fermentation time should be prolonged due to its high cellulose lignosin.
2. The PH value will also affect the efficiency of organic fertilizer fermentation. The pH of organic fertilizer fermentation is neutral or weakly alkaline. We can use quicklime to regulate the pH of the fermentation product to control the fermentation of compost.
3. After 72 hours of general composting, the temperature will rise to 50-60 °C, and the fourth day can reach more than 65 °C. At this high temperature, it is recommended to start loose processing, using a compost dumper to process the material. Generally, in the fermentation process, there will be a high temperature of 2-3 times above 65 ° C, and the fermentation can be completed after 2-3 times of overturning, so that the material is completely deodorized, fermented and decomposed, sterilized and disinfected. Kill insects.
As a fertilizer application machinery manufacturer with many years of experience, we provide advanced nitrogen, phosphorus and potassium fertilizer manufacturing processes and organic fertilizer production lines for customers in need around the world, as well as high-quality technical services.
Generally speaking, the organic fertilizer production process includes:
Organic materials crushing (chain crusher)→composting (compost turner)→mixing compost with other ingredients (horizontal blender)→granulation(organic fertilizer granulator)→drying (rotary dryer)→ cooling (rotary cooler) →sieving (rotary screen)→packaging (automatic fertilizer packager)
Organic fertilizer production raw materials selection, the machine is also very key, we welcome you to consult at any time.
