Features of Small Scale Fish Feed Plant

Many benefits of fish feed pellets

Many benefits of fish feed pellets

Rich in nutrition and easy to digest and absorb

Fish feed pellets are rich in protein, fat, carbohydrates, and a variety of vitamins and minerals. They can meet the various nutrients required for fish growth and development, provide balanced nutritional support for fish, thereby promoting healthy and high-quality growth of fish, improving the quality of fish meat, enhancing fish immunity, and improving the overall health of fish. In the small scale fish feed plant, the feed raw materials undergo physical and chemical changes under the action of high temperature and high pressure, making the nutrients easier for fish to digest and absorb. This not only improves the utilization rate of feed, reduces the waste of feed in water, but also reduces the risk of water pollution, which is conducive to maintaining a good breeding environment and further ensuring the healthy growth of fish.

Easy to store and transport

Fish feed pellets can be stored for two to three months under appropriate storage conditions, such as covered storage in a cool and dry place. Compared with some bulk or unprocessed feeds, its shelf life is significantly extended, reducing the waste caused by feed deterioration and reducing breeding costs. The granular feed has a regular shape, which is easy to stack and store, and can make full use of limited storage space. At the same time, its packaging is more standardized, easy to handle and manage, further improving the efficiency of storage and transportation, and reducing feed loss during storage and transportation.

Avoid animal picky eating

Because the fish feed pellets are uniform in size and the nutrients are evenly distributed, it can effectively avoid the situation of fish picky eating. This ensures that fish can take in balanced nutrition, promotes the uniform growth of the entire fish population, and improves the overall benefits of breeding. During the high temperature and high pressure processing, not only can the germs and pathogens in the feed raw materials be killed, the risk of disease transmission can be reduced, but also the nutrients in the raw materials can be better preserved. At the same time, this processing technology can also improve the stability and durability of the feed, making it less likely to disperse in the water, further improving the quality and performance of the feed.

Rich raw materials and broad market prospects

Small scale fish feed plant has strong raw material adaptability. It can be flexibly formulated according to a variety of raw materials such as fish meal, soybean meal, corn, rice bran, etc. available locally, which is convenient for production. This makes its production process very flexible. It can flexibly adjust the formula and production process according to the raw material supply and market demand in different regions to reduce production costs. With the continuous development of the aquaculture industry, the demand for high-quality fish feed continues to grow. Fish feed pellets have broad prospects and high profit returns in the market due to their many advantages. In addition, it can also be made into pellet feeds of different specifications and densities according to different growth stages and fish species to meet diverse market needs, further enhancing the market competitiveness and economic benefits of the product.

Single screw floating fish feed extruder machine

Single-screw extrusion extruder machine is a device specially used for the production of floating fish feed pellets. It extrudes and puffs the raw materials under high temperature and high pressure through a rotating screw, so that the feed pellets can float on the water surface and facilitate fish feeding. Its structure is relatively simple, easy to maintain, relatively low cost, and can be widely used in small and medium-sized aquaculture farms and fish feed farms, suitable for the production of common floating fish feed. It is divided into two processes: dry method and wet method:

Dry method

The raw materials need to be added with water, but no conditioning is required before entering the extrusion bin. The extrusion heat is completely generated by mechanical extrusion, and no steam system is required. The equipment is relatively simple, easy to operate and maintain, and low in cost, but the output is relatively limited, which is suitable for small and medium-sized users.

Dry method Single screw floating fish feed extruder machine

Wet method

The raw materials need to be pre-conditioned before entering the extrusion chamber. With the help of steam or water to increase the temperature, the starch is pre-gelatinized, the protein is denatured, and the raw materials are softened, which improves the extrusion quality. The produced feed particles are smoother and of better quality. It is suitable for large-scale production in medium and large feed processing plants and aquaculture farms.

Wet method Single screw floating fish feed extruder machine

The following are the specific parameters of the two processes:

Production process of Small Scale Fish Feed Plant

The main function of small scale fish feed plant equipment is to process various raw materials into feed suitable for fish through mixing, crushing, granulation and other processes. Below I will take 0.5 T/H small fish feed production line as an example to briefly introduce how to use the production process of this production line to make fish feed pellets. The following is a detailed production process flow:

Production process of Small Scale Fish Feed Plant

The following is the detailed production process:

01 Raw material storage and transportation system

Including raw material bin, conveyor belt, etc., used to store and transport various raw materials.

02 Raw material reception and cleaning

Raw materials are mainly in the form of powder and granules. Powder can be directly put into the batching bin, and granules need to be coarsely crushed. The raw materials need to be cleaned to remove impurities to ensure the quality of the raw materials.

03 The first batching and mixing

The first batching is mainly the preparation of the materials with larger proportions in the formula, which is completed by the electronic batching scale. After batching, it enters the first mixing to reduce the variation range of the material particle size and improve the working condition of the grinder.

04 The second crushing

Due to the poor digestion ability of aquatic animals, the feed particle size is required to be very fine. After the second crushing process is completed, it enters the rotary grading screen to remove the crude fiber in the feed.

05 The second mixing

After the second batching, the raw materials enter the second mixer to add trace additives and liquid.

06 Conditioning and puffing

The materials are cooked under high temperature, high humidity and high pressure, and the physical and chemical properties change to form puffed feed. Puffed feed has the advantages of high starch gelatinization, easy protein digestion and good palatability.

07 Cooling, drying and screening system

It is used to cool, screen and dry the pelletized feed to prevent the feed from deteriorating. The purpose of screening the feed is to remove unqualified particles and package them for easy storage and transportation.

08 Product grading and packaging

The cooled materials are lifted, crushed and then enter the grading screen for grading. The final product goes directly into the finished product warehouse and is then weighed and packaged.
