Process flow of small-scale fish feed production line
1、 Introduction
With the rapid development of aquaculture, the demand for fish feed is also increasing day by day. In order to meet this demand, small-scale fish feed production lines have emerged. This article will provide a detailed introduction to the process flow of a small-scale fish feed production line, including raw material processing, ingredients, mixing, pressing, drying, cooling, and packaging.
2、 Process flow of small-scale fish feed production line
1. Raw material processing
Raw material processing is the first step in small-scale fish feed production lines. At this stage, it is necessary to clean, dry, crush, and mix the raw materials. Cleaning is to remove impurities and harmful substances from raw materials; Drying is to reduce the moisture content of raw materials for subsequent processing; Crushing is the process of breaking raw materials into particles suitable for processing; Mixing refers to mixing different types of raw materials in a certain proportion to meet the nutritional needs of fish.
2. Ingredients
Ingredients are a key link in the production line of small fish feed. At this stage, it is necessary to weigh and mix various raw materials in a certain proportion according to the formula requirements. The formulation of the formula needs to fully consider factors such as the type, growth stage, and nutritional requirements of fish to ensure that the produced fish feed can meet the growth needs of fish.
3. Mixing
Mixing is the process of thoroughly mixing pre mixed ingredients into a mixer. The purpose of mixing is to thoroughly mix various raw materials and improve the uniformity and stability of the feed. Factors such as mixing time, mixing speed, and mixing method can all affect the mixing effect, so adjustments need to be made according to the actual situation.
4. Suppression
Pressing is the process of putting mixed raw materials into a press for pressing. The press compresses raw materials into granular feed of a certain shape and size through squeezing and cutting actions. During the pressing process, it is necessary to control parameters such as temperature, pressure, and speed of the press to ensure that the quality and shape of the feed particles meet the requirements.
5. Drying
Drying is the process of placing compressed pellet feed into a dryer for drying treatment. The dryer reduces the moisture content in feed pellets to a certain extent through hot air circulation and temperature control, making it easier to store and transport. Drying time and temperature parameters need to be adjusted according to the type and moisture content of the feed.
6. Cooling
Cooling is the process of cooling the dried pellet feed. Cooling can lower the temperature of feed pellets, avoiding damage and spoilage caused by high temperatures. Meanwhile, cooling can also make the feed particles more compact, increasing the density and shelf life of the feed.
7. Packaging
Packaging is the final step in the production line of small fish feed. At this stage, it is necessary to package the cooled pellet feed for sale and storage. Packaging materials need to meet hygiene standards and be able to resist moisture, insects, and mold. At the same time, the packaging needs to indicate product name, specifications, production date, shelf life, and other information for consumers to understand and use.
3、 Conclusion
The process flow of a small-scale fish feed production line includes raw material processing, batching, mixing, pressing, drying, cooling, and packaging. Each stage requires strict control of operating parameters and quality standards to ensure that the produced fish feed meets the growth needs of fish. With the continuous advancement of technology and changes in market demand, small-scale fish feed production lines will also be continuously optimized and improved to meet market demand and improve production efficiency.
