Organic fertilizer and bio-fertilizer
Bio-organic fertilizer refers to a type of microbial fertilizer and organic fertilizer that is composed of specific functional microorganisms and organic materials that are mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. Effective fertilizer. If the process is changed, the product can be upgraded to produce a series of products such as organic-inorganic compound fertilizer, bio-organic fertilizer and compound microbial fertilizer.
Organic fertilizer production process
Including crushing, batching, mixing, granulating, drying, cooling, screening and packaging. Key elements of fertilizer production: formulation, granulation, and drying.
2. Process flow (see Figure 1)
Factory construction model and planning
1. The integrated model is suitable for fertilizer companies that rely on outsourcing of raw materials.
2. The decentralized on-site fermentation and centralized processing model is applicable to large-scale breeding enterprises and their affiliated enterprises.Determine how much space is needed based on the scale of breeding and the amount of manure processed
Process design and equipment selection principles
The principles of process design are: practical principle; aesthetic principle; conservation principle; and environmental protection principle.
Principles for equipment selection are: The equipment layout is smooth and the structure is compact, so as to save space as much as possible and reduce the main investment in the building; the equipment is strong and durable, with low maintenance rate, low system energy consumption and low operating costs; the equipment is easy to operate, minimizing manual operations and reducing labor strength.
site selection
The organic fertilizer processing plant should maintain a sanitary protection distance of more than 500m from the farm production area, residential area and other buildings, and be located in the production area of the livestock and poultry farm, with the living area in the downwind or crosswind direction.
The location of the site should be conducive to emissions, resource utilization and transportation, and should leave room for expansion to facilitate construction, operation and maintenance.
The main raw materials are concentrated, large in quantity, and easy to pick up and transport; transportation and communication are convenient; water, electricity and other energy sources are guaranteed; it is as far away from residential areas as possible; large-scale characteristic agricultural planting areas.
Compost plant layout
1. Layout principles
including the principles of order and efficiency
2. Regional principles
Functional division of production area, office area and living area. Office and living areas should be arranged in the year-round upwind direction of the entire project.
3. System layout
Impact of system characteristics on the production environment.
4.Planning of Compost Plant
Following the principles of environmental optimization, conducive to production, land saving, easy management, convenient life and moderate beautification, the fermentation site can be set up independently near the raw material area, or the fermentation site, deep processing workshop and office area can be planned together at the target site.
Basic conditions for project investment
1.Raw materials
There should be sufficient livestock and poultry manure in the surrounding area, and livestock and poultry manure accounts for about 50%-80% of the formula.
2. Factory buildings and warehouses
According to the investment scope, for example, for a factory with an annual output of 10,000 tons, the factory warehouse should be 400-600 square meters, and the site should be 300 square meters (fermentation site 2,000 square meters, processing and storage site 1,000 square meters)
3. Excipients
Rice husk and other crop straws
4. Activity funds
Working capital depends on the supply of raw materials.
Determination of the scale of organic fertilizer plant for construction of dry manure technology farms
1.Principles
The scale of organic fertilizer construction is determined based on the amount of livestock and poultry manure. The scale is generally calculated based on the production of 1kg of finished product for every 2.5kg of fresh manure.
2. Calculation method
The annual output of organic fertilizer multiplied by 2.5 multiplied by 1000 and then divided by the daily manure production of livestock and poultry multiplied by 360 equals the number of breeding animals.
Complete set of equipment for organic fertilizer production line
The organic fertilizer production process is closely related to the equipment configuration of the organic fertilizer production line. Generally, the complete set of equipment of the organic fertilizer production line mainly consists of a fermentation system, a drying system, a deodorization and dust removal system, a crushing system, a batching system, a mixing system, a granulation system, a screening system and finished products. Packaging system composition.
Development prospects of organic fertilizer production from livestock and poultry manure
With the vigorous promotion of organic fertilizer in ecological agriculture, farmers have a certain understanding and recognition of it, and the demand for organic fertilizer in the international agricultural market will continue to increase.
1. Organic fertilizer made from livestock manure, straw and other fermented and processed by beneficial microorganisms has the advantages of low investment, easy availability of raw materials, and low cost. Its ecological benefits cannot be ignored.
2. The rapid development of organic agriculture and the continuous rise in chemical fertilizer prices have favorably stimulated the activity and growth of the international organic fertilizer market, attracting farms and fertilizer manufacturers to carry out organic fertilizer processing, and the abundant poultry and livestock manure has become the source of organic fertilizers. The fertilizer industry provides a huge and stable raw material space.
3. The nutritional value and economic value of agricultural products produced using organic fertilizers are very high.
4. Bio-organic fertilizer processing technology and technical equipment are increasingly perfected, and agricultural standards such as bio-organic fertilizer have been formulated and implemented one after another, providing strong technical support for organic fertilizer factories.
Therefore, with the development of the livestock and poultry industry and people’s demand for pollution-free green food, the demand for organic fertilizers made from livestock and poultry manure will be increasing, and it will have broader development prospects!
