Characteristics of pellets made by Small floating fish feed machine
The fish feed pellets made by floating fish feed extruder machine are not only uniform in appearance and moderate in density, but also more suitable for various aquatic animals to eat, effectively improving feed utilization and reducing breeding costs. The following are several core characteristics of fish pellets.
The pellets have good buoyancy. This equipment uses a high-temperature and high-pressure puffing process to form a porous structure inside the pellets, which can float stably in the water for 6 to 12 hours, reducing feed sinking waste and facilitating observation of fish feeding conditions, thereby accurately feeding, improving feed utilization efficiency, and reducing water pollution.
The pellets are regular in shape and adjustable in size. By changing the mold aperture, Small electric fish feed extruder machine can produce fish feed pellets with diameters ranging from 1mm to 10mm, which can meet the nutritional needs of various growth stages from fry to adult fish. The pellet length can be adjusted by a cutter, which is suitable for the feeding habits of fish of different sizes.
The pellets are nutritionally balanced and have a high digestibility. Since the raw materials have been fully crushed and evenly mixed before pelleting, and heated and matured by the conditioner during the extrusion process, the obtained pellets have less nutritional loss, moderate protein denaturation, and are conducive to digestion and absorption. At the same time, the puffing process can inactivate anti-nutritional factors and harmful bacteria in the raw materials to ensure the health of fish.
The pellets have moderate hardness and are not easy to break. The density of the pellets can be controlled by adjusting the puffing process parameters to adapt to the feeding methods of different fish. The pellets are not easy to break, there is less loss during transportation, and the finished product has a neat appearance, which improves market competitiveness.

Introduction to the main equipment of Small floating fish feed machine
Small floating fish feed machine is one of the core equipment in fish feed manufacturing plant. It can produce high-quality feed pellets for various types of aquatic animals, such as fish feed pellets, catfish feed pellets, crab feed pellets, shrimp feed pellets, etc., and also includes various floating, sinking and slow-sinking aquatic feeds to meet the feeding needs of different fish.
There are many types of Small fish feed pellet machines. At present, the twin-screw fish feed puffing machine is the most widely used, most convenient to use, and has a self-cleaning function, which is suitable for the extrusion processing of various materials. Therefore, the most common floating fish feed puffing machines can be divided into single-screw floating fish feed puffing machines and twin-screw floating fish feed puffing machines according to the number of screws. The following is a detailed introduction:
Single screw floating fish feed extruder machine
The single screw extruder is a device specially used for the production of floating fish feed pellets. It extrudes and puffs the raw materials under high temperature and high pressure through a rotating screw, so that the feed pellets can float on the water surface and facilitate fish feeding. Its structure is relatively simple, easy to maintain, relatively low cost, and can be widely used in small and medium-sized aquaculture farms and fish feed farms, suitable for the production of common floating fish feed. It is divided into two processes: dry method and wet method:
Dry method: The raw materials need to be added with water, but no conditioning is required before entering the extruder bin. The extruder heat is completely generated by mechanical extrusion, and no steam system is required. The equipment is relatively simple, the operation and maintenance are relatively convenient, the cost is low, but the output is relatively limited, which is suitable for small and medium-sized users.
Wet method: The raw materials need to be pre-conditioned before entering the extruder bin. With the help of steam or water to increase the temperature, the starch is pre-gelatinized, the protein is denatured, and the raw materials are softened, which improves the extruder quality. The produced feed particles are smoother and of better quality. It is suitable for large-scale production of medium and large feed processing plants and aquaculture farms.
The following are the specific parameters of the two processes:
| Parameters | Dry extruder machines (DGP Series) | Wet extruder machines (DSP Series) |
