Main technical and economic indicators

Raw materials and energy consumption

The main raw materials and energy consumption of this organic fertilizer manufacturing plant in Mexico project are shown in the following table:

The plant ash of this organic fertilizer manufacturing plant in Mexico project comes from the waste of biomass power plants. Since ammonia water is sprayed during the denitrification process of the power plant, the raw material plant ash of this project will produce volatile ammonia during the production process. Since plant ash is the ashes after the burning of plants, almost all the mineral elements contained in plants are contained in plant ash.

The most abundant element is potassium, which generally contains 6~12% potassium, of which more than 90% is water-soluble and exists in the form of carbonate; followed by phosphorus, which generally contains 1.5~3%; it also contains trace nutrients such as calcium, magnesium, silicon, sulfur, iron, manganese, copper, zinc, boron, and molybdenum. The composition analysis of the plant ash of this project is shown in the attachment.

Fermented okara: okara refers to the by-product of the production process of soy products such as tofu and soy milk. Under normal circumstances, every 10 kilograms of soybeans can produce about 7 kilograms of dry okara, which generally contains about 8% fiber, about 28% protein, and about 12.40% fat. The fermented okara is easier to preserve and has richer nutrients. The crude protein content is generally around 28%, the crude fiber content is around 6%, and the dry okara contains about 27.7% crude protein.

Project General Plan Layout

Based on the requirements of convenient management, land conservation and smooth production process, the organic fertilizer manufacturing plant in Mexico project divides the plant area into raw material storage area, raw material mixing area, production and processing area, finished product storage area and office and living area according to functional areas.

The production and processing area is located in the middle of the plant area, mainly for crushing, screening and mixing processes; the raw material storage shed is located on the north and south sides of the production plant processing area; the finished product area is located on the west side of the production and processing area; the office and living area is located on the southwest side of the plant area.

In general, the project plant area combines road construction to meet the process flow of production and processing, as well as the requirements of raw materials, finished product entry and exit, water, electricity, roads, etc. The functional areas are clearly divided, the layout is reasonable, and the process flow layout is smooth and feasible. Therefore, the general plan layout of this project is reasonable and feasible.

Process flow design

The production process of the organic fertilizer manufacturing plant in Mexico project is to use livestock and poultry manure, fermented bean dregs, plant ash, biological bacteria, etc. in a certain proportion, add agricultural microbial verification agents, adopt aerobic fermentation technology, through cultivation, fermentation, turning, crushing, etc., and finally add a small amount of trace elements.

After product quality testing, a powdered finished product is obtained. The product content is N+P2O+K2O greater than or equal to 4%, and the organic matter content is ≥30%. It takes 10 days for each batch of raw materials from the access to the bacterial agent to the final product.

The organic fertilizer pellet plant has a total of 4 fermentation tanks, which ferment at the same time. The output of each batch of products is about 700-800 tons, and 20,000 tons of organic fertilizer are produced annually.

1. Incoming materials: The raw materials of the project are mainly fermented bean dregs, plant ash, and biological bacteria. They are pulled into the factory area by trucks and placed in the raw material storage warehouse of the production workshop for storage and waiting. The raw materials are stored in the workshop and generally do not generate dust, but only a small amount of unloading dust.
2. Mixing: The purchased raw materials are shoveled into the hopper in proportion (fermented bean dregs and plant ash in a ratio of 2:1) using a bulldozer bucket. The mixed raw materials are simply mechanically mixed in the hopper, and the mixed materials are then loaded by a bulldozer and then conveyed to the crusher via a belt.
3. Crushing: The mixed materials are transported from the mixing workshop to the production workshop via a belt conveyor, and then conveyed to the vertical crusher via a belt conveyor for crushing. The crusher is only equipped with a feed port and a discharge port. After feeding, the feed port is closed and crushing is carried out to crush the materials to less than 8 mm.
4. Screening: The crushed materials are conveyed to the pellet machine, and then to the cooler machine, and finally to the drum screening machine by a belt conveyor. The materials are screened with a drum screen, and the large pieces of materials screened out are returned to the crushing process through a belt conveyor for crushing. The screened materials are transported to the packaging machine through a belt conveyor and directly packaged to obtain powder products. According to the construction unit, the distance between the belt conveyor and the feeding port of the packaging machine is relatively close (<20cm).
5. Packaging: The qualified materials are transported to the automatic packaging machine through a belt conveyor for packaging.

The current status of the organic fertilizer manufacturing plant in Mexico project does not adopt a fully enclosed factory building, and there are no collection and treatment measures for waste gas. This environmental impact assessment recommends the use of a closed steel structure factory building with multiple gas collection ports on the top of the factory building and a micro-negative pressure design.

The ammonia, hydrogen sulfide and dust generated in the production process are led to the waste gas treatment facilities (bag dust collector + activated carbon adsorption) through a negative pressure collection pipeline, and then discharged into the air through a 15m exhaust pipe after treatment.

Prevention and control measures to be taken by the construction project

What are the procedures for building a small organic fertilizer manufacturing plant in Mexico?

Now that environmental protection is getting worse and worse, many breeding farms are facing the problem of environmental demolition and reconstruction. How to solve this problem?

Just buy the small organic fertilizer pellet line produced by RICHI MACHINERY to solve this problem. Is it profitable to build a small organic fertilizer production line? What are the process flows of building an organic fertilizer production plant?

• Choose the area of your own site.
  Generally, customers should see if they are suitable for building their own production line. If they are large breeders, it is more appropriate to choose an organic fertilizer production line with an annual output of 10,000 tons. If it is a customer who invests in building a small organic fertilizer production factory, it should be close to the raw materials. According to the actual situation, choose an organic fertilizer plant that suits you.
• Understand the organic fertilizer granulation process and choose the organic fertilizer production equipment that suits you.
  Organic fertilizer is the process of fermenting, turning and crushing livestock and poultry manure into organic fertilizer. The compost turning machine should be determined according to the area of your own site. The mobile compost turning machine has a relatively large area. Because according to the actual situation to choose their own production line equipment.
• Understand the market situation of organic fertilizer.
  With the implementation of the national coal to gas policy, the price of chemical fertilizer has soared, and the source of organic fertilizer is simple. If organic fertilizer is applied in the greenhouse, it can not only increase the indoor humidity and maintain the quality of crops, but also kill harmful bacteria in crops. The utilization rate of organic fertilizer reaches 90%, while the utilization rate of chemical fertilizer can reach 90%. The market prospect of organic fertilizer is very promising.

The procedures required for building an organic fertilizer manufacturing plant in Mexico include environmental pollution assessment, industrial and commercial business license, factory planning and construction, trademark application, normal operation of the enterprise and national registration procedures.
