The raw materials of animal manure organic fertilizer and bio-organic fertilizer can be selected from various animal manure and organic waste. The basic formula of production varies with different types and raw materials.
The basic raw materials are: chicken manure, duck manure, goose manure, pig manure, cattle and sheep manure, crop straw, sugar industry filter mud, bagasse, sugar beet residue, vinasse, medicine residue, furfural residue, fungus residue, soybean cake, cotton kernel Cake, rapeseed cake, grass charcoal, etc.
Organic fertilizer production equipment generally includes: fermentation equipment, mixing equipment, crushing equipment, granulation equipment, drying equipment, cooling equipment, fertilizer screening equipment, packaging equipment, etc.
The production process of organic fertilizer is mainly composed of: fermentation process-crushing process-mixing process-granulation process-drying process-screening process-packaging process and so on.
The fermentation of organic raw materials from livestock and poultry manure 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, relatively thorough matrix decomposition, short composting cycle, low odor, and large-scale use of mechanical treatment.
Generally, the temperature of aerobic composting is high, generally 55-60℃, and the limit can reach 80-90℃. Therefore, aerobic composting is also called high-temperature composting. Aerobic composting uses the action of aerobic microorganisms under aerobic conditions. ongoing. During the composting process, the soluble substances in livestock manure are directly absorbed by the microorganisms through the cell membranes of the microorganisms; the insoluble colloidal organic substances are first adsorbed outside the microorganisms and decomposed into soluble substances by the extracellular enzymes secreted by the microorganisms, and then penetrate into the cells. .
1. First of all, the raw materials such as poultry manure must be fermented to maturity. The harmful bacteria in the fermentation process can be killed, which is the most important thing in the entire organic fertilizer manufacturing process. The composting machine realizes the complete fermentation and composting of the fertilizer, and can realize the high-stacking and fermentation, which improves the speed of aerobic fermentation.
2. Secondly, use the crushing equipment to enter the fermented raw materials into the crusher to crush the large pieces of materials into small pieces that can meet the requirements of granulation.
3. Ingredients are a key step in fertilizer production. Its main function is to add appropriate ingredients in proportion to make the organic fertilizer rich in organic matter and improve the quality.
4. After the materials are uniformly mixed, they must be granulated. The crushed materials are sent to the mixer equipment by a belt conveyor, mixed with other auxiliary materials, and then enters the granulation process.
5. The granulation process is the core part of the organic fertilizer production line. The granulator is used to produce dust-free particles with controllable size and shape. The granulator achieves high-quality uniform granulation through continuous mixing, collision, inlay, spheroidization, granulation, and compaction processes.
6. The water content of the granules after granulation by the granulator is high, and it needs to be dried to reach the standard of water content. The material gets high temperature through the drying process, and then it needs to be cooled down, because water can not be used for cooling, so cooling equipment is needed here.
7. The screening machine needs to screen out the unqualified granular fertilizer, and the unqualified materials will also return to the production line for qualified treatment and reprocessing.
8. Fertilizer conveyor plays an indispensable role in the fertilizer production process. It connects different parts of the entire production line.
9. Packaging is the last link in the fertilizer equipment. After the fertilizer particles are coated, they are packaged by the packaging machine. The packaging machine has a high degree of automation, integrating weighing, stitching, packaging, and conveying to achieve rapid quantitative packaging, making the packaging process faster and more accurate.
