The process flow of small-scale fish feed production line

With the development of aquaculture, the demand for fish feed is increasing day by day. In order to meet this market demand, small fish feed production lines have attracted widespread attention due to their advantages such as small footprint, low investment cost, and easy operation. This article will provide a detailed introduction to the process flow of a small-scale fish feed production line to help readers better understand this process.
1、 Raw material preparation
The first step in a small-scale fish feed production line is the preparation of raw materials. According to the nutritional requirements of fish and the formula of feed, select appropriate raw materials, such as soybean meal, fish meal, corn meal, wheat bran, bone meal, vitamins and minerals. These raw materials need to be crushed, screened, and processed to ensure uniform particle size for subsequent mixing and molding.
2、 Mixing and granulation
After raw material preparation, various raw materials are mixed thoroughly in a certain proportion into the mixer. During the mixing process, it is necessary to ensure the uniform distribution of various raw materials to ensure the balance of feed nutrients. After mixing, the raw materials enter the granulator for granulation. During the granulation process, feed particles of different sizes and shapes can be obtained by adjusting the pressure and speed of the granulator.
3、 Drying and cooling
The feed pellets after granulation contain high moisture and require drying treatment. Small fish feed production lines usually use hot air drying to control the drying time and temperature to ensure that the moisture content of feed particles meets the standard requirements. The temperature of the dried feed pellets is relatively high and requires cooling treatment to avoid spoilage during storage and transportation.
4、 Screening and packaging
The cooled feed particles enter the screening machine for screening to remove particles and impurities that do not meet the requirements. The screened feed particles are packaged in packaging machines, usually using well sealed packaging bags to prevent moisture and contamination of the feed. After packaging, the feed can enter the market for use by breeding households.
5、 Quality testing and recording
Quality inspection is an indispensable part of the entire production process. Small fish feed production lines should be equipped with corresponding testing equipment and instruments to conduct regular testing of raw materials, semi-finished products, and finished products to ensure that the quality of feed meets standard requirements. At the same time, production records should also be kept, including information on the source of raw materials, production date, production batch, etc., for traceability and management.
In summary, the process flow of a small-scale fish feed production line includes raw material preparation, mixing and granulation, drying and cooling, screening and packaging, as well as quality testing and recording. These links are interconnected and together constitute the complete fish feed production process. By optimizing the process flow and improving equipment performance, the production efficiency and quality of fish feed can be further improved, providing strong support for the development of aquaculture industry.
