Precision-Engineered Sinking Fish Feed Machine
Sinking Fish Feed Machine Overview
A sinking fish feed machine is a complete set of specialized equipment designed for the production of sinking or slow-sinking fish feed. It encompasses the entire production workflow, from raw material crushing to the packaging of the finished product.
Not only that, but our sinking fish feed making machine also possesses powerful versatility. In addition to producing fish feed grains, it can also produce shrimp and crab feed. Our equipment can precisely adjust processing parameters to suit the specific needs of different aquaculture species, producing the most suitable feed pellets.

Core sinking fish feed Machine
RICHI sinking fish feed machine primarily comprises a crusher, mixer, pelletizer, dryer, cooler, screener, packaging machine, and other auxiliary equipment. Among these components, the fish feed pelletizer serves as the core pelletizing unit.
Fish Feed Pellet Making Machine
RICHI sinking fish feed machine mainly include two types: fish feed pellet mills and fish feed extruders. These two machines use different feed processing technologies. The fish feed pellet making machine compresses raw materials into dense pellets through strong pressure between the ring die and rollers. In contrast, the fish feed extruder processes materials under high temperature and pressure. It cooks and modifies the material inside the extrusion chamber. When the material is pushed out from the die holes, it expands and puffs up rapidly. As a result, it forms porous and loose feed pellets.

Fish Feed Pellet Making Machine
RICHI fish feed pellet making machine includes the ring die pellet mill and the flat die pellet mill. We recommend that customers purchase ring die feed pellet mills because they have higher capacity, more uniform pellets, and longer die life, resulting in long-term overall benefits that far exceed those of flat die pellet mills.

Frequently Asked Questions
Below are some questions you may have. If you have any inquiries, please feel free to contact us.
–
How well do your sinking fish feed making machine handle high-oil formulations?
Our sinking fish feed machine utilizes a high-compression-ratio ring die and a forced feeding system to ensure that high-oil materials are still tightly formed, resulting in smooth, non-loose pellets. The pressure rollers and ring die are specially coated to reduce material slippage or die blockage caused by oil. However, if your formulation contains more than 10% oil, we recommend using an oil spraying machine to apply the coating after the pellets have cooled.
–
How long is the service life of wear parts (screw, barrel, die)?
With proper maintenance, our wear-resistant alloy steel components typically last 1000+ hours, depending on the abrasiveness of the raw materials.
–
How much does a set of sinking fish feed making machine cost?
The price depends on capacity, configuration, and automation level. Please contact us with your requirements (capacity, target species, pellet type) for a customized quotation.
–
Can the pellet size be adjusted according to different fish growth stages?
Yes. By changing the ring mold of the sinking fish feed making machine and adjusting the cutting device, the size and length of the pellets can be precisely controlled to meet the feeding needs of fish of different sizes (from fry to adults).
–
What kind of after-sales service do you offer?
RICHI Machinery provides a 12-month warranty on its sinking fish feed machines. In addition, we offer a long-term supply of original spare parts at competitive prices. Furthermore, RICHI provides on-site installation and operation training services for all customers. (view our YouTube)
