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.

Introduction to the main equipment of fish feed manufacturing plant
Floating fish feed extruder machine is one of the core equipment of the fish feed manufacturing unit. It can produce high-quality feed pellets for a variety of types of aquatic animals, such as fish feed pellets, catfish feed pellets, crab feed pellets, shrimp feed pellets, etc., and also includes various floating, sinking and slow-sinking aquatic feeds to meet the feeding needs of different fish.
There are many types of fish feed pellet making machines. At present, twin-screw fish feed extruder machine is the most widely used, most convenient to use, and has self-cleaning function, suitable for extrusion processing of various materials. Therefore, the most common floating fish feed extruder machines can be divided into single-screw floating fish feed extruder machines and twin-screw floating fish feed extruder machines according to the number of screws. The following is its detailed introduction:
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 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 following are the specific parameters of the two processes:
| Parameters | Dry extruder machines (DGP Series) | Wet extruder machines (DSP Series) |
| Model | DGP-90B / DGP-120B / DGP-160B | DSP-90B / DSP-135B |
| Main Motor Power (kW) | 37 / 55 / 90 | 37 / 75 |
| Feeding Motor Power (kW) | 0.75 / 2.2 / 3 | 7.5 / 7.5 |
| Cutting Motor Power (kW) | 0.55 / 1.1 / 1.5 | 1.1 / 1.5 |
| Conditioning Motor Power (kW) | – (No Pre-Conditioning Needed) | 1.1 / 2.2 |
| Screw Diameter (mm) | 90 / 120 / 160 | 90 / 135 |
| Overall Dimensions (mm) | 2100×1450×1350 / 2400×1950×1600 / 3100×2650×1800 | 2600×1600×1900 / 3750×1980×1950 |
| Output (Ton/Hour) | 0.2–0.4 / 0.5–0.6 / 0.8–1.0 | 0.5–0.6 / 0.8–1.0 |
Twin screw floating fish feed extruder machine
Fish feed twin screw extruder machine is a highly efficient granulation equipment commonly used for processing fish feed. Its working principle is to extrude the material from the feed port to the discharge port through two rotating screws, and at the same time heat and pressurize the material to turn it into fluid. This equipment is widely used in aquaculture and other industries because of its high efficiency, flexibility and high-quality production characteristics, and is widely concerned and loved by various industries.
Floating fish feed extruder has high capacity and low energy consumption. Fully kneaded screw technology is used to ensure uniform feed pellets and improve the granular curing effect with an efficient tempering device. The equipment operates stably and safely, has a low failure rate, and can also produce a variety of aquatic feed.
The following are its detailed technical parameters:
| Model | Production Capacity (tons/hour) | Main Motor Power (KW) | Screw Diameter (mm) | Matching Differential Speed Regulator Model Power |
| RCPH120*2 | 1 – 2 | 75 | 120 | DDC40×30 – 244 11 kW |
| RCPH120*2 | 3 – 4 | 90 | 120 | DDC40×30 – 244 11 kW |
| RCPH150*2 | 4 – 5 | 160 | 150 | DDC50×30 – 244 11 kW |
| RCPH150*2 | 6 – 7 | 200 | 150 | DDC50×30 – 244 11 kW |
| RCPH185*2 | 8 – 10 | 315 | 185 | DDC50×30 – 300 15 kW |
| RCPH185*2 | 10 – 12 | 355 | 185 | DDC50×30 – 300 15 kW |
Other auxiliary equipment of fish feed manufacturing plant
In addition to the main production machines, a complete fish feed manufacturing plant also relies on a variety of auxiliary equipment to ensure smooth, efficient, and high-quality production. These supporting machines play vital roles in material preparation, processing, cooling, and final packaging. Below, we briefly introduce several commonly used auxiliary devices.
Feed crusher
Feed crusher is suitable for crushing various feed raw materials, such as corn, wheat, beans, crushed cakes, etc. Widely applicable to large and medium-sized livestock and poultry and aquatic feed enterprises. In addition, the RICHI SFSP series water drop hammer crusher adopts an advanced water drop crushing chamber design, a reasonable secondary crushing structure, and can efficiently crush aquatic feed raw materials.
Feed mixer
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
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
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 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
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.
Fish feed manufacturing plant process flow: receiving part → crushing part → ingredients and mixing part → micro-pulverizing part → mixing part → extruder and drying part → packaging part
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
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.
