Fertilizer products can be made into granules or powder, depending on the market demand, in order to balance nutrients, suitable for transportation and storage, it is recommended to process organic and inorganic compound fertilizers into granular products. The equipment used for its production is called the Fertilizer processing machine. The moisture content requirements of the finished granules produced are organic fertilizer ≤ 20%, organic-inorganic compound fertilizer ≤ 10%.
Fertilizer processing machine equipment:
Fertilizer processing machine includes various types of fermentation and throwing equipment, granulation equipment, crushing equipment, particle drying, and cooling equipment, stirring equipment, automatic batching system, dehydration equipment, screening equipment, automatic packaging equipment, etc. Among them, the granulator, as one of the hosts of the Fertilizer processing machine, is divided into a variety of granulators (rotary drum granulator, rotary drum stirring teeth two-in-one granulator, disc granulator, Double roller granulator, New type organic fertilizer granulator, etc.).
Fertilizer processing machine to produce organic fertilizer method:
Fertilizer processing machine production methods of organic fertilizer mainly include 1) raw material preparation; 2) fermentation and decomposing; 3) granulation and molding; 4) quality control. In the preparation of raw materials: chemical analysis and pulverization of the ingredients of the raw materials are required. When mixing the raw materials, it is necessary to adjust the moisture, adjust the carbon-nitrogen ratio and adjust the pH. In the process of fermentation and decomposing: it is necessary to inoculate fermentation bacteria, conduct aeration to ensure that the heap contains suitable oxygen, and turn over to control the temperature of the heap and promote the distribution of water. Fermented and decomposed organic fertilizers can be directly applied to field crops or pelleted. In the granulation and forming process: it needs to go through 7 steps crushing, batching, mixing, granulation, drying, functional bacteria (sometimes can be added), and cooling. The prepared granular organic fertilizer is generally used for flowers, fruits and vegetables, and greenhouse crops. In order to ensure the quality of organic fertilizer, it is necessary to carry out quality control, detect relevant indicators of organic fertilizer, and then judge whether it is qualified according to the standard of organic fertilizer.
The significance of Fertilizer processing machine to produce organic fertilizer:
For crops, organic fertilizers can fertilize the soil and provide comprehensive nutrients, so that crops can grow better. For the breeding link, the production of organic fertilizer can reduce the pollution of the farm to the environment and increase the income other than animal products.
1. Reduce environmental pollution: environmental protection standards
In the resource utilization of livestock and poultry breeding waste, the production of organic fertilizer is the top priority. Only by properly disposing of the solid waste (mainly manure) that accounts for most of the farm, can the pollution of the farm to the environment be truly reduced, and the farm can meet the environmental protection standards. Now, whether the environmental protection of the farm meets the standard is already a question related to the existence of the farm.
2. Income increase: Organic fertilizer is expensive and is one of the ways to increase farm income
The advantages of organic fertilizers over chemical fertilizers are long fertilizer efficiency, not ease to “burn seedlings”, and will not cause soil compaction. In addition, agricultural products grown with organic fertilizers have the characteristics of longer shelf life, richer nutrients, and better taste. Therefore, organic fertilizers are more and more favored by farmers, and organic fertilizers have been widely used as fertilizers for fruits and vegetables.
The price of organic fertilizer made from chicken manure fermentation is about 2,000 yuan per ton (after granulation). The cost of organic fertilizer produced from pig manure ranges from about 300-400 yuan per ton, while the price of pig manure organic fertilizer generally ranges from about 700-800 yuan per ton (after pelleting).
