The fish feed production plant is widely used in aquaculture. The production line can be used in freshwater fish, seawater fish and shrimp breeding fields, as well as the production of floating fish feed, sinking fish feed, and shrimp feed. The following briefly lists the common application areas:

Floating Fish Feed

It is mainly suitable for some fish that move in the middle and upper layers, such as common grass carp and bream. These fish usually feed in the upper and middle layers of the water body, and floating feed can facilitate them to find and ingest food in time. Moreover, farmers can visually see the feeding status of the fish, reasonably adjust the feeding amount, and avoid feed waste.

Sinking Fish Feed

Suitable for fish living at the bottom of the water body, such as carp, black carp, etc. They are used to looking for food at the bottom of the water. Sinking feed can meet their feeding habits, ensure that the feed can reach their activity area, ensure nutrient intake, and also reduce the loss of feed in the upper and middle layers of the water body.

Shrimp Feed

Suitable for a variety of shrimps, such as white shrimp, crayfish, etc. Shrimp feeding methods are different from fish. Shrimp feed will specifically add substances needed for shrimp growth in terms of nutrients, such as astaxanthin, etc., to meet the physiological needs of shrimp, help shrimp grow healthily, shed shells, etc., and improve breeding efficiency.

Fish feed pellets are high in energy and rich in protein, fat, and carbohydrates. This balanced nutrition improves fish meat quality, strengthens immunity, and promotes healthy, efficient growth. The pellets are also fully cooked under high temperature and pressure, making nutrients easier to digest and absorb while reducing feed waste.

Compared to other feed types, pellets have a compact and uniform shape, allowing for efficient storage and transportation. When kept in a cool, dry, and covered space, they can be stored safely for 2 to 3 months, significantly reducing feed spoilage and loss.

The high-temperature, high-pressure manufacturing process helps eliminate harmful bacteria and pathogens present in raw materials, ensuring safer and more hygienic feed for aquatic animals.

Fish feed pellets can be made from a wide variety of raw materials and customized in different sizes and densities to suit various species and growth stages. Their wide application, ease of production, and profitability make them highly attractive in both local and international aquaculture markets.

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 extruder bin. The extruder heat is completely generated by mechanical extrusion, and no steam system is required. The equipment is relatively simple, the operation and maintenance are relatively convenient, the cost is low, but the output is relatively limited, which is suitable for small and medium-sized users.

Wet method: The raw materials need to be pre-conditioned before entering the extruder bin. 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 extruder quality. The produced feed particles are smoother and of better quality. It is suitable for large-scale production of medium and large feed processing plants and aquaculture farms.

The feed mixer is used to evenly mix the crushed raw materials to ensure uniform proportions of each component. Moreover, the RICHI mixer adopts a novel rotor structure, with a mixing uniformity of up to 97.7%, and a short mixing time.

Feed Cooler

Feed Cooler

The feed cooler mainly cools the newly extruded hot pellets to avoid cracking of the pellets due to quenching. In this way, it can effectively protect the structure of feed pellets and improve the quality of feed.

Feed packaging machine

Feed packaging machine

The feed packaging machine automatically completes the packaging of feed pellets, which is highly automated and adapts to the needs of large-scale production, and has attracted the attention and love of many fish feed factories.

Vacuum spraying

Vacuum spraying

Vacuum spraying equipment is mainly used to spray nutrients such as oil, enzyme preparations, etc. on the surface of fish feed particles. The equipment adopts a sealed design and operates under a negative pressure environment, so that the spraying liquid can penetrate into the particles, spray more evenly, and adsorb more firmly. Compared with traditional spraying methods, vacuum spraying can greatly improve the nutrient preservation rate and particle quality, and is an important part of fish feed production.

Feed dryer machine

Feed dryer machine

Fish feed dryer machine is an indispensable and important equipment in the fish feed production line. It is mainly used to quickly and evenly dry the high-temperature and moist feed pellets that have just been extruded. Through drying, the moisture content of the pellets can be effectively reduced, the storage stability and transportation adaptability of the pellets can be improved, and mold and deterioration can be prevented.

Production technology of fish feed manufacturing plant

The main function of the fish feed manufacturing unit equipment is to process various raw materials into feed suitable for fish feed through mixing, crushing, granulation and other processes. Next, I will take the 5T/H floating 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.

Equipment configuration of this feed production line: Feed crusher → bucket elevator → feed mixer → ultra-micro crusher → floating fish feed machine → dryer → sprayer → countercurrent cooler → screening → packaging machine

5T/H floating fish feed production line

The following is the detailed production process:

01 Raw material storage and conveying system

Including raw material silos, conveyor belts, etc., used to store and convey various raw materials.

02 Raw material reception and cleaning

The raw materials mainly include two forms: powder and pellets. The powder can directly enter the dosing silo, and the pellets need to be coarsely crushed. The raw materials need to be removed through cleaning equipment to ensure the quality of the raw materials.

03 First ingredients and mixing

The first ingredients are mainly the preparation of materials with relatively large amounts in the formula, and are completed by electronic ingredients scales. After batching, enter the first mixing, reduce the range of variation in material pellet size and improve the working condition of the crusher.

04 Second crushing

Due to the poor digestibility of aquatic animals, the feed crushing pellet size is required to be very fine. After the second crushing process is completed, enter the rotary grading screen to remove the crude fibers from the feed.

05 Second mixing

After passing through the second batching, each raw material enters the second mixer, and adds trace additives and liquids.

06 Conditioning and extruder

The material is steamed and cooked under high temperature, high humidity and high pressure, and changes in physical and chemical properties occur, forming puffed feed. Puffed feed has the advantages of high gelatinization of starch, easy to digest protein, and good palatability.

07 Cooling, drying and screening system

Used to cool, screen and dry the granulated feed to prevent the feed from deteriorating. The feed is screened to remove unqualified pellets and package them for easy storage and transportation.

08 Product grading and packaging

The cooled material is lifted, broken and then entered into a grading screen for grading. The final product directly enters the finished product warehouse and then weighs and packages.
