What is Sinking Fish Feed Pellet Mill?
This sinking fish feed machine has a higher production capacity than flat die pellet machines. It is more often used for commercial fish feed pellet production for big capacity plants like sinking fish feed, shrimp feed, and other aquatic feed. The finished feed pellets have a smooth surface and are easy to digest for animals.
This sinking fish feed pellet mill adopts mature technology to make high-quality pellets with large-scale production. This is based on the outstanding features of its high throughput and low consumption. It offers a large capacity of 0.5-10t/h, and can make pellet sizes from 1.5mm to 5mm for different fishes. Larger capacity pellet plants are realized by connecting several pellet mills in parallel to reach a capacity up to 15-20 ton/hour.

Core Advantages for Sinking Aquatic Feed
The pressure of the sinking fish feed pellet mill is much higher so that the pellet it makes has a higher density and smoother surface. It can ensure excellent water stability for sinking fish feed. While a single conditioner is sufficient for poultry feed, our multi-layer conditioner design makes vastly superior pellets for rigorous aquatic environments.
Our precise gear design minimizes slip, saving energy and ensuring the perfect temperature for high-quality feed pellets. This design generates less wear and tear since both the inner and outer edges of the roller traverse the same distance.


Sinking Fish Feed Machine Features
- Advanced Conditioning System: The sinking fish feed machine adopts a three-layer jacket conditioner. Inside the conditioner, Food Grade 304 Stainless Steel paddles maintain an optimal temperature of 85°C to 95°C and a moisture content of 15% – 18%. The material can be fully cooked to ensure the quality of final aquatic feed.
- Smart Feeding Mechanism: When putting the powder raw materials inside the sinking fish feed pellet mill door, you can feed them with a surge bin through a variable speed conditioner. A screw auger is significant for the last step to sending materials into the sinking fish feed making machine chamber.
- High-Precision Drive: Main driving adopts high precision gear transmission, and the capacity can be improved about 20% compared to the belt transmission, with low energy consumption.
- Premium Components: Our sinking fish feed pellet mill uses German bearings and oil seals, and is equipped with a Denmark original imported Danfoss inverter and PLC control system, making it convenient to operate while saving labor costs.
- 24/7 Continuous Operation: The sinking fish feed machine features an automatic grease-adding system. The one-piece main shaft allows for adding oil without stopping the machine, which greatly improves production efficiency for 24/7 operations.


How to Choose the Right Machine for Sinking Fish Feed?
- 0.5 – 1.0 t/h (Farm Startup): The HMK-250 is the smallest model with compact structure. It is the only one industrial-grade sinking fish feed pellet making machine which is suitable for small fish farms and feed factories, and those who want to produce industrial-grade fish feed.
- 2.0 – 5.0 t/h (Commercial Scale): This type is the one with optimized compression ratio which is specially good for producing 2.0mm sinking fish feed. You can get highest dense fish feed pellets and higher water stability.
- 8.0 – 10.0 t/h (Industrial Grade): The model of HMK-420 is best for those who want to produce commercial sinking fish feed and large production capacity. It has reinforced gearbox which can handle heavy duty and continuous production.
