This is a 6t/h fish feed mill in Brazil project. The client was originally a livestock and poultry feed processing plant.
Brazil is one of the fastest growing countries in aquaculture in the world, with an annual growth rate of about 5-8%. The main aquaculture species (tilapia, catfish, shrimp) rely on artificial feed. Brazil plans to double its aquatic production by 2030 (currently about 800,000 tons/year), and the demand for feed will surge simultaneously. For investors, Brazil is one of the most promising markets in the field of fish feed in South America.
Based on this background and the company’s development needs, the client decided to expand the aquatic feed production line in the vacant land in the northeast corner of the project.
After the completion of the fish feed mill plant project, the annual production scale of 50,000 tons of aquatic feed can be achieved. At the same time, during this expansion process, a 6-ton natural gas boiler (equipped with a low-nitrogen burner) will be added according to environmental protection requirements. The original 4-ton natural gas boiler will be equipped with a low-nitrogen burner and used as a standby boiler. The factory currently has a labor quota of 40 people, including 15 management personnel and 25 production personnel. This renovation and expansion project will add 15 new labor quotas. The working hours are 330 days, with three shifts and 8 hours per shift.

Process design of fish feed mill in Brazil
The production process of this fish feed mill in Brazil project is mainly divided into ten sections. The detailed process flow is as follows:
- Raw material reception: Raw materials that need to be coarsely crushed (such as fish meal, cake meal and other large-particle raw materials) are put into the feeding hopper and then transported to the crushing bin through the elevator. Raw materials that do not need to be coarsely crushed are directly transported to the corresponding batching bin. A pulse dust collector is set separately at the feeding port to reduce dust.
- Raw material coarse crushing: Raw materials that need to be coarsely crushed need to be crushed by a crusher before entering the batching bin, and the particles pass through a 2.00mm sieve.
- First mixing: The ingredients are automatically batched through the central control system according to the formula table. The static accuracy of the batching scale is 1‰ and the dynamic accuracy is 5‰. Various solid additives are put into the small material feeding port. After the ingredients are batched, they are stirred and mixed in a double-shaft paddle-type high-efficiency mixer. The stirring time is generally about 5 minutes, and the coefficient of variation of the mixing uniformity is ≤7%.
- Ultrafine grinding: After the first mixing, the material is sent to the ultrafine grinder for ultrafine grinding. After ultrafine grinding, the material is screened and magnetically separated before entering the second mixer.
- Second mixing: While the material enters the secondary mixer, liquid additives, internal oils, etc. are added according to the required amount, and the second stirring and mixing begins. The stirring time is generally about 5 minutes, and the coefficient of variation of the mixing uniformity must be ≤7%.
- Tempering, puffing, and granulation: The evenly mixed material enters the conditioner and is tempered by controlling the amount of water and steam added. The tempering temperature is above 90 degrees, and the moisture content after conditioning is about 26%. Then it is sent to the floating fish feed extruder machine to start extrusion.
- Drying: The newly made feed pellets are sent to the dryer for drying. The temperature control is determined according to different feed varieties and particle sizes. The moisture content of the product meets the standard requirements of the customer company.
- External spraying of grease: After the feed is dried, it enters the differential weight liquid sprayer for external oil spraying, and the spraying is required to be uniform.
- Cooling and screening: After the oil spraying is completed, it enters the cooler. This fish feed mill in Brazil adopts a countercurrent cooler. Then, the corresponding screen is selected according to the product category for screening and enters the finished product warehouse.
- Packaging: The finished product packaging system includes an electronic packaging scale and a belt conveyor sewing machine, which can accurately and quickly complete the finished product packaging.
General layout
The plant area of this fish feed mill in Brazil project has a total of 1 raw material workshop and 1 finished product workshop. The main feed production workshop and 2 raw material silos are built between the two workshops. The living area is arranged in the southeast corner of the plant area, and the boiler room and other auxiliary rooms are arranged on the east side of the plant area. The aquatic feed workshop to be renovated and expanded is arranged in the northeast corner of the plant area, relying on the existing raw material silos for raw material pretreatment. The interior of the aquatic feed workshop is arranged horizontally and vertically in strict accordance with the requirements of the process, and each dust-generating point is equipped with a dust collector.
Since the process flow of this project is highly correlated and the semi-finished products also have a strong internal designated flow direction, the relevant production workshops and auxiliary workshops are mostly arranged nearby, which is conducive to the transportation of materials and shortens the transportation route.
In summary, the general layout plan has the characteristics of smooth process flow, convenient transportation within the field, and power and auxiliary production facilities as close to the load center as possible. In addition, the main power equipment is arranged in the center of the plant area, which can effectively reduce the impact of power noise on the acoustic environment of the plant boundary. Therefore, the general layout of this project is reasonable.
Why is it suitable to build a fish feed mill in Brazil?
There are many advantages and potentials in building a fish feed mill in Brazil, mainly based on the following key factors:
1. Rich aquatic resources and mature aquaculture
The world’s leading aquaculture country: Brazil is the largest fish producer in Latin America, and the scale of freshwater aquaculture (such as tilapia, catfish, shrimp) and marine aquaculture continues to expand, and there is a strong demand for fish feed.
Superior natural conditions: The Amazon Basin and numerous freshwater lakes provide an ideal environment for aquaculture, and feed supply is the core link of the industrial chain.
2. Adequate raw material supply
Advantages of a large agricultural country: Brazil is one of the world’s largest producers of soybeans and corn (soybean meal and corn are the main sources of protein and energy for fish feed), which can reduce the cost of raw material procurement and transportation.
Abundant animal by-products: By-products (blood meal, bone meal) of the meat processing industry (such as poultry and beef) can be used as feed additives to improve resource utilization.
3. Market demand growth
Domestic consumption upgrade: With population growth and increased awareness of healthy eating, Brazil’s per capita consumption of aquatic products has increased year by year, driving the expansion of the aquaculture industry.
Export potential: The demand for Brazilian farmed fish in South America and the global aquatic market (such as the United States and Europe) has increased, indirectly stimulating the demand for feed.
4. Policy and infrastructure support
Government incentives: Brazil encourages investment in agriculture and aquaculture through tax incentives, subsidies and other policies, such as the “More Fisheries and Aquaculture” program.
Convenient logistics: The main aquaculture areas are close to ports (such as the north and northeast), which is convenient for the import of raw materials and the export of finished products; the inland transportation network (roads, rivers) is gradually improving.
5. Technology and cost advantages
Localized production reduces costs: reduces dependence on imported feed (currently some high-end feed still needs to be imported), and has stronger price competitiveness.
Technical adaptability: Special formulas can be developed for local fish species (such as tilapia) to improve breeding efficiency.
6. Sustainable development potential
Green energy: Brazil’s electricity is mainly hydropower, and the production cost is low-carbon and environmentally friendly.
Circular economy: The use of agricultural waste (such as bagasse) to develop biofeed is in line with the global sustainable trend.
Brazil’s agricultural resources, aquaculture scale, market demand and policy support make it a strategic choice for building fish feed production lines. Investors can focus on major aquaculture areas (such as Paraná, São Paulo or Amazonas), taking into account local supply and export markets, while using sustainable raw materials to improve competitiveness.
