The development of green agriculture must first solve the problem of soil pollution. Common problems in soil include: soil compaction, imbalance of mineral nutrient ratio, low organic matter content, shallow farming layer, soil acidification, soil salinization, soil pollution and so on. To make the soil suitable for the growth of crop roots, it is necessary to improve the physical properties of the soil. Increase the organic matter content of the soil, make the soil aggregate structure more, and less harmful elements in the soil.
Organic fertilizer is made of animal and plant residues, after being fermented in a high-temperature process to harmlessly eliminate toxic and harmful substances, it is rich in a large amount of organic substances, including: a variety of organic acids, peptides, and nitrogen, phosphorus, and potassium The rich nutrients. It is a green fertilizer that is beneficial to crops and soil.
The organic fertilizer production process is mainly composed of: fermentation process-crushing process-mixing process-granulation process-drying process-screening process-packaging process and so on.
1. The first is the fermentation of organic raw materials from livestock and poultry manure:
It plays a very important role in the entire organic fertilizer production process. Sufficient fermentation is the basis for the production of high-quality organic fertilizer. The modern composting process is basically aerobic composting. This is because aerobic composting has the advantages of high temperature, thorough matrix decomposition, short composting cycle, low odor, and large-scale use of mechanical treatment.
2. Raw material ingredients:
According to market demand and the results of soil testing in various places, the livestock and poultry manure, crop straw, sugar industry filter mud, bagasse, sugar beet residue, distiller’s grains, medicine residue, furfural residue, fungus residue, soybean cake, cotton cake, rapeseed cake, Raw materials such as grass carbon, urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate, potassium chloride, etc. are prepared in a certain proportion.
3. Mixing of raw materials for fertilizer equipment:
Stir the prepared raw materials evenly to increase the uniform fertilizer efficiency content of the entire fertilizer particles.
4. Raw material granulation for organic fertilizer equipment:
The uniformly stirred raw materials are sent to the granulator of the organic fertilizer equipment for granulation.
5. Then the pellet drying:
The granules made by the granulator are sent to the dryer of the organic fertilizer equipment, and the moisture contained in the granules is dried to increase the strength of the granules and facilitate storage.
6. Cooling of dried particles:
The temperature of the dried fertilizer particles is too high and easy to agglomerate. After being cooled, it is convenient for bagging storage and transportation.
7. The particles are classified by the organic fertilizer sieving machine:
The cooled fertilizer particles are screened and classified, the unqualified particles are crushed and re-granulated, and the qualified products are screened out.
8. Finally, pass the organic fertilizer equipment automatic packaging machine:
Put the coated fertilizer particles, which is the finished product, into bags and store them in a ventilated place.
