What is Wet Type Fish Feed Extruder?
Wet type fish feed extruder is the core equipment in the aquafeed industry for the large-scale production of high-quality floating/sinking fish feed.
Unlike dry-type extruders, wet-type fish feed extruders are equipped with a conditioner. Raw materials
enter the conditioner where steam and water are injected, and maturation, gelatinization and sterilization are completed under high temperature and high pressure.
This process gelatinizes starch and denatures protein, improving pellet stability and digestibilit. Meanwhile, it allows precise control of pellet density to produce qualified floating and sinking pellets. The materials are then extruded through the die holes and expanded by instant pressure release to form feed pellets.

How A Wet Type Fish Feed Extruder Works
The wet type fish feed extruder works by steam conditioning, high-pressure extrusion, and instant expansion.
Raw materials are mixed and treated with steam, then compressed and cooked under high temperature and pressure to improve gelatinization and digestibility. After passing through the die, the material expands into pellets, which are cut, dried, and cooled to ensure stable quality and good floating performance.
Versatile Applications for Various Aquatic Species
RICHI wet type fish feed extruder can process a wide variety of raw materials, including corn, soybean meal, fish meal, wheat bran, rapeseed meal, and various local grain by-products. Through steam conditioning and high-temperature extrusion, it produces floating, slow-sinking, or sinking pellets with stable quality. With strong formula adaptability and precise density control, it meets the diverse feed requirements of fish, shrimp, crabs, and even pet food production.
