FISH FEED MACHINE
Fish feed machine is a specialized machine designed for producing fish/shrimp feed. It serves as the core equipment in fish/shrimp feed processing.
As a professional fish feed machine manufacturer, RICHI can offer you fish feed pellet machine and fish feed extruders including twin screw extruder, wet type extruder, dry type extruder amd more.
FISH FEED MACHINE TYPES
Many people want to produce fish/shrimp feed pellets, but there is more than one type of fish feed machine. Different farming needs, feed formulas and aquatic animal species determine that we need different types of pelleting equipment to match.
RICHI provides a variety of efficient and durable fish feed making machines, which can meet the different production needs from individual-scale farming to large-scale feed mills.
Fish Feed Pellet Machine
By changing the ring die with different hole sizes and shapes, this machine can produce feed pellets with precise diameters and uniform lengths. It is suitable for processing starches (corn, wheat, potato starch), medium-protein (soybean meal, fish meal, cottonseed meal), low-fat and low-fiber raw materials. Mainly used for sinking fish feed, shrimp feed, and crab feed. Floating fish feed (requiring expansion process) is outside this equipment’s production scope.

Fish Feed Extruder Machine
Fish feed extruder can produce floating, sinking, and slow-sinking feeds. It can also meet diverse needs—from fry to adult fish and conventional to specialty aquaculture species. Simply adjusting screw speed, extrusion temperature, water addition, and die structure, you can control feeds’ maturity, density, and form. Additionally, only parameter adjustments enable switching between aqua animal feed types (e.g., sea bass feed to shrimp feed), making it perfect for mixed-culture farming scenarios.

Floating Fish Feed Machine
This fish feed machine supports customized production of high-density feed–from high floatability to slow-sinking (suspension)–by adjusting ingredients, temperature, and moisture. It meets the feeding needs of bass, catfish, trout, tilapia, and some ornamental fish, while also suiting intensively managed, modern aquaculture operations with high-quality feed demand.

Sinking Fish Feed Machine
Sinking fish feed machine produces feed that quickly sink to the bottom or mid-lower water layers. The sinking pellets are dense and durable, resisting disintegration from water currents. It suits bottom-feeding fish (black carp, catfish, common carp, and crucian carp). Its processing features make it ideal for handling high-starch (soybean meal, wheat bran, fish meal) and low-fat ingredients.

twin screw extruder
RICHI twin screw extruder makes diverse feed types—floating, slow-sinking, sinking feeds for fish/shrimp/crabs, and dog/cat food—by adjusting screw speed, dies, moisture, and temperature. It handles high-fiber, high-fat, and high-moisture ingredients that single-screw extruders struggle to process. Serving large-scale, high-quality feed manufacturers, it targets the mid- to high-end aquaculture and specialty markets (pet food).

Single Screw Extruder
It produces multiple particle sizes of standard hard pellets and basic sinking fish feed. Suitable for processing common cereal grains (corn, wheat, sorghum) and low-fiber, low-fat ingredients (soybean meal, cottonseed meal). Targets small-to-medium-scale, cost-sensitive, routine feed production. Forms a complementary “basic vs. high-end” positioning alongside twin screw extruder.

Dry Type Extruder
Forming pellets via high-pressure screw extrusion, resulting in low-moisture, hard pellet feed. Its steam-free conditioning makes it suitable for processing high-fiber raw materials (bran, alfalfa meal) and low-heat-sensitivity raw materials (like vitamin B1/C, enzymes). Ideal for producing feed for bottom-dwelling fish (e.g., grass carp, black carp, and carp) and pet snacks (e.g., chew sticks, hard pellet dog food).

Wet Type Extruder
Producing high-moisture soft pellets by “steam conditioning + screw extrusion”. Can process high-protein ingredients (fish meal, whey powder, soybean meal), high-fat ingredients, and probiotics. Suitable for making floating feeds (for top-water fish like ornamental fish, sea bass, mandarin fish) or slow-sinking feeds (for mid-water fish like tilapia and yellow catfish), as well as crustaceans (shrimp, crab, and crayfish).

FISH FEED MACHINE APPLICATION
Different fish species live at different water depths and have different feeding habits, so fish feed pellets are designed with various properties. For example, floating feed pellets suits surface-feeding fish; Sinking feed pellets quickly drop to the bottom; And slow-sinking feed pellets target mid-water species.
Producing these diverse feed types relies on advanced fish feed processing equipment. With professional fish feed machines, pellet density and sinking speed can be precisely controlled.
Floating feed for salmon
Floating feed for tilapia
Sinking feed for catfish
Sinking feed for eel
Slow-sinking feed fot trout
Slow-sinking feed for bass
Fish Feed Machine for Multiple Animal Feed production
Fish feed machines can not only produce a variety of fish feeds, but are also suitable for the production of aquatic animal feeds such as shrimp and shellfish. And can even meet the production needs of cat and dog pet food.
By using professional aquatic fish feed machines or multi-functional pellet feed production equipment, users only need to replace different-sized molds and adjust the corresponding processing parameters, and can flexibly produce high-quality pellet feed that meets the nutritional needs of different animal species, growth stages and varieties.

PROCESS IN HIGH-QUALITY FISH FEED PELLET MAKING
The general fish feed production process includes: receiving and cleaning raw materials – crushing and mixing – pelletizing or extruding- drying – spraying – cooling and packaging. This is the most common way fish feed is made. However, different fish feed plants may change the fish feed production process based on their needs. For example, some make feed for specific types of fish, while others focus on higher output. These needs can affect how the fish feed production process is set up.

fish feed production section Description
Receiving and Cleaning Raw Materials
+
Receive and prepare raw materials such as grains, soybean meal, fish meal, and oils. Remove impurities to make sure the materials are clean and of good quality.
Crushing and Mixing
+
Break large pieces into small powder. Then mix all the materials in the right amounts using a mixer. This makes sure the nutrition is evenly spread in every feed pellet.
Pelletizing or Extruding
+
Turn the mixed material into feed pellets. Depending on the product type, use either a feed pellet machine for regular pellets or an extruder for floating or sinking aquafeed.
Drying
+
Newly made pellets often have high moisture. Use a dryer to reduce water content to a safe level. This helps prevent mold and keeps the feed fresh for longer.
Spraying
+
After drying, spray oil, vitamins, amino acids, or other nutrients onto the surface of the pellets. This step is also known as “post-spraying” and helps improve taste and nutrition.
Cooling & Packaging
+
The pellets remain hot after drying and need to be cooled to near room temperature with a cooler. Only then are they screened to remove fines, followed by automatic weighing and packaging as per customer requirements.
