What is dry type fish feed extruder?
Dry type fish feed extruder is one type of floating fish feed extruder machine. Based on the production process, floating fish feed extruders are generally divided into two types: dry type fish feed extruder and wet type fish feed extruder. While both are used to produce floating or sinking aquatic feed pellets, the dry type extruder operates without steam and is more suitable for small-scale production.
Dry type fish feed mill is a feed processing equipment designed for aquatic animals such as fish, shrimp, crab, etc. It is also often called dry fish feed pellet machine or low-cost catfish feed machine. It mainly extrude various grain raw materials such as corn, soybean meal, wheat bran, etc. through high temperature and high pressure to make floating or sinking aquatic feed with balanced nutrition, uniform pellets and easy digestion.
Unlike wet extruders, dry fish feed extruders do not require an external steam system, so the structure is simpler and the investment is lower. It is especially suitable for small and medium-sized fish farms, cooperatives and feed processing plants. This equipment can not only significantly reduce feed costs, but also flexibly adjust pellet size and formula according to the feeding needs of different fish species, improve feeding efficiency and survival rate, so it is particularly popular in developing regions. Dry fish feed extruder is an important tool for achieving refinement, cost control and localized processing of aquaculture.
The video shows a test run of RICHI’s floating fish feed production line project in Ukraine. It demonstrates how the dry type fish feed extruder operates in real production, forming floating pellets with stable shape and smooth cutting.

Working principle of dry type fish feed extruder
The core working principle of dry type fish feed extruder is to use the main shaft to drive the screw, so that the raw materials are subjected to high temperature, high pressure and high shear force between the screw and the screw sleeve, and ripen, expand and form. Specifically, after the material enters the spiral cavity through the feed port, it gradually heats up due to mechanical friction and compression, starch gelatinizes, and protein denatures, which improves the palatability and digestibility of the feed.
When the material reaches the front end of the mold, it is extruded under high pressure and immediately cut into pellets. The angle and speed of the cutter can be freely adjusted to control the length of the pellets. No additional steam support is required during the whole process. The heat energy comes from the mechanical energy conversion generated by the equipment itself, which is easy to operate and has low energy consumption.
The extruded pellets are not only controllable in size, but also can be selected in floating or sinking state according to needs to adapt to the feeding habits of different types of aquatic animals. The whole machine has a compact structure, and the components are made of wear-resistant alloy steel. It has a long service life and is easy to maintain. It is an economical and practical solution for aquatic feed processing.

While the dry type fish feed extruder machine is a widely used single-screw feed extruder with the advantage of lower cost and easier maintenance, it’s important to note that it represents only one type of fish feed pellet making machine. Another popular type is the Wet Type Fish Feed Extruder, which uses steam and a conditioner to pre-cook the feed materials before extrusion. This method ensures better gelatinization, higher production capacity, and is more suitable for large-scale feed mills.
In addition, many customers also prefer the twin-screw floating fish feed extruder, which features advanced mixing and self-cleaning capabilities. It provides more flexibility in processing diverse materials and offers superior pellet quality. Depending on your production scale, feed formula, and desired pellet properties, RICHI Machinery can help you choose the most suitable fish feed extrusion solution.

Application of dry type fish feed extruder in fish feed production line
With the rapid development of aquaculture, the demand for high-quality fish feed has also increased significantly. Among many feed processing equipment, dry fish feed extruder stands out for its easy operation, cost-effectiveness and ability to produce floating fish feed pellets. Below is a detailed presentation of a fish feed production line with an output of 0.7–0.8 tons per hour, demonstrating how the system is combined with a dry extruder to produce nutritionally balanced and easily digestible fish feed pellets.
Production process:
Receiving section → Crushing section → Batching and mixing section → Fine grinding section → Second mixing section → Extrusion and drying section → Packaging section
Main equipment configuration:
Feed crusher → Bucket elevator → Feed mixer → Ultra-micro crusher → dry type fish feed extruder machine → Rotary dryer machine → Sprayer → Countercurrent cooler → Screener → Packaging machine
Fish feed production process details:
01 Raw material storage and transportation
Raw materials such as rice bran, soybean meal, and corn are stored in silos and transported to the processing site through a belt conveyor system. Proper storage can prevent contamination and ensure feed quality.
02 Receiving and pre-cleaning
Raw materials are delivered in the form of powder or granules. Powder can be directly delivered to the batching bin, while granules need to be coarsely ground. Pre-cleaning equipment can remove impurities to ensure the safety and quality of the feed.
03 First batching and mixing
The main raw materials are weighed using an electronic batching scale and then sent to the primary mixing. This step helps reduce pellet size differences and prepares the feed for further grinding.
04 Secondary pulverization
Aquatic animals have weak digestive systems, so the feed must be pulverized again. After the second pulverization, the feed passes through a rotary grading screen to remove crude fiber.
05 Secondary mixing
All raw materials are re-dosed and sent to the second-stage mixer, where micronutrients and liquids (such as oil or enzymes) are added to maintain nutritional balance.
06 Conditioning and extrusion
This is the core process. The dry extruder cooks the feed at high temperature and pressure without adding steam. The extruded pellets expand and float on the water surface. This stage is essential for starch gelatinization, improving protein digestibility and improving palatability.
07 Drying, cooling and screening
The hot pellets are sent to the dryer to reduce the moisture content, and then to the cooler to stabilize the shape and prevent mold. After that, the sifter removes pellets that are too large or too small.
08 Product classification and packaging
The cooled pellets are classified using a grading screen and then sent to the packaging machine. The finished product is weighed and packed into bags, ready for shipping or storage.
