Aquatic Feed Pellet Plant Production Process
This production line solution features a scientifically designed process flow, encompassing the basic stages of raw material crushing, mixing, pelletizing, drying, oil spraying, cooling, screening, and packaging. Each stage is equipped with robust main machinery and auxiliary systems, ensuring the production system operates with high efficiency and energy savings. We will tailor the configuration of each stage to meet your specific production requirements.
01. material crushing
Some raw materials cannot be processed directly, such as grains like corn, wheat, and sorghum. If your raw material is already in powder form, this stage is not required. The main equipment in this stage is a precision hammer mill, which produces particles ranging from 3 to 5 mm in size.
02. material mixing
The crushed material can be fed into the mixer along with other powdered raw materials. The batching process is controlled by an automated system and performs precise batching according to two predetermined ratios. The liquid addition system adds oils to the mixer, ensuring rapid and uniform mixing.
03. Feed forming
This section is equipped with a pelletizer or an extruder. After entering them, the material is heated to 85°C using high-temperature steam to ensure thorough gelatinization, and then undergoes a shaping process to produce pellet feed. Different pellet sizes can be achieved by replacing the ring die or the die head.
04. Feed Drying
We have designed a mesh belt recirculating dryer specifically for gentle drying of feed pellets or fragile food products. It dries freshly produced, moist feed to a moisture content of 2–10%. This facilitates greater oil absorption during the coating process and extends the feed’s shelf life.
05. Cooling and Screening
Pellets after oil spraying still retains a relatively high temperature following drying. We have designed a counter-flow cooler specifically for these pellets. Featuring an octagonal structure, a slide-gate discharge system, it can minimize pellet loss. When paired with a vibrating screen, it enhances efficiency.
06. Feed Packaging
The packaging section is equipped with a fully automatic granule packaging scale that supports gravity, belt, or auger feeding. The high level of automation in this section further enhances production efficiency and ensures consistent packaging specifications. At the same time, it significantly reduces labor costs.
Key Equipment for Aquatic Feed Pellet plant
The following is the primary equipment configuration for this aquatic feed pellet plant. These components play a vital role in their respective production stages. In addition to these, we also offer other types of equipment for the same stages. They offer the advantages of high efficiency, energy savings, and ease of operation, providing numerous benefits for your aquatic feed production.
Raw Material Crusher
The hammer mill can crush small-sized grains, such as corn, wheat, oilseed meal, and legumes used in fish feed. The crushed material is reduced to a size of 3–5 mm, making it easier to pelletize.
Feed Mixer
It can blend various feed production materials. The mixed ingredients can be extruded into feed pellets with a more uniform texture, thereby ensuring consistent nutritional content in every pellet.
Aquaculture Feed Pellet Mill
This pellet mill is designed for sinking fish and shrimp feed, enabling precise control over pellet density and water resistance. It is typically equipped with two to three conditioning units.
Floating Fish Feed Pellet Machine
This extruder offers both single-screw and twin-screw and can produce floating, sinking, and non-sinking feeds. The feeds balance palatability and water resistance, meeting high-quality standards.
Mesh Belt Dryer
Freshly extruded fish feed pellets can have a moisture content of over 22%. This gentle mesh belt dryer can reduce the moisture content of feed pellets by more than 10%, extending the feed’s shelf life.
Spraying Machine
It sprays edible oil or attractants onto feed pellets to enhance the palatability. Feed pellets treated with oil spraying have a smoother and more even surface, thereby meeting the high-quality feed needs.
cooling machine
This unit cools and sets the dried feed, lowering its temperature from 80°C to just above room temperatures by 3–5°C.This helps solidify the fats in the feed, facilitating packaging and transportation.
Vibrating Screen
This is a vibrating screen that separates particles into two size grades while removing dust from their surfaces, thereby ensuring consistent particle quality. It is typically assembled with a cooler.
Packaging System
It enables automatic weighing and packaging, facilitating product sales. The packaging size is typically 10 to 50 kg per bag. You can use heat sealing, string sealing, or a combination of both.

What is the difference between pelleted and extruded feed?
When making granular aquatic feed (sinking feed pellets), firstly, crush different raw materials with a crusher, and then mix them with a feed mixer machine. The mixed raw materials are semi-finished products of fish or shrimp formula feed. Next is the process of making pellets. The premixed formula feed enters the fish feed pellet making machine, and then the pressing roller and the ring die press out the granules (granules). The diameter dimension of the ring die is the diameter of the feed pellets. The ring dies with different diameters are used when making different sizes of pellet feeds.
When making extruded pellet feed (floating feed pellets), firstly, raw materials are crushed. If the raw material for floating fish feed is powder, it does not need to be crushed. Then mix the powder evenly. After that, the aquatic feed raw materials are uniformly fed into the floating fish feed extrude machine. Under great extrusion pressure and high temperature, the extruded feed pellets will expand when coming out of the floating fish feed extruder machine and become pellets, which can float on the water’s surface.

What are the advantages of pellet feed?
As far as production is concerned, pellet feed has a series of advantages, such as low investment cost, high output, low unit production cost, fast return on capital, etc. In addition, compared with the natural food and unprocessed grain feed, pelletized feed is easier to store, package and transport. For fish farmers, the price of pellet feed is low but the feed coefficient is high, which not only makes the main cultured fish (such as grass carp, crucian carp, and carp) grow well but also makes the mixed cultured fish (such as silver carp and perch) grow well.
When making extruded pellet feed (floating feed pellets), firstly, raw materials are crushed. If the raw material for floating fish feed is powder, it does not need to be crushed. Then mix the powder evenly. After that, the aquatic feed raw materials are uniformly fed into the floating fish feed extruding machine. Under great extrusion pressure and high temperature, the extruded feed pellets will expand when coming out of the floating fish feed extruder machine and become pellets, which can float on the water’s surface.

How to select the right pelletizing equipment?
A fish feed making machine is a feed processing machine that takes corn, soybean meal, straw, grass, and rice husk as raw materials and directly presses them into pellets after crushing raw materials. It is better suited for the production of conventional sinking aquafeeds.
The twin screw floating fish feed extruder machine has the advantages of strong adaptability, sliding transportation, and self-cleaning. Therefore, a twin-screw floating fish feed extruder machine is generally used in aquatic feed pellet plant or pet feed production, such as eel, sea fish, juvenile fish feed, and other high-added value aquatic products and pet feed pellets.

How to produce clean aquaculture feed pellets?
We can incorporate a raw material screening step before the crushing section. Raw materials that do not need to be crushed are input from the auxiliary feeding port, and sundries and bulk materials are removed through the fence and then transported to the main cleaning screen through the conveyor and elevator to remove ropes and large debris. The raw materials enter the magnetic separator to remove the metal debris and then enter the batching warehouse to wait for batching.
The dust generated by the feeding enters the bag-type dust removal system for negative-pressure dust removal. The raw materials to be crushed pass through the fence to remove impurities. The hoist is sent to the main cleaning screen to remove impurities such as ropes and labels. Then the iron impurities are removed by the permanent magnet cylinder and then enter the warehouse for crushing.
