Features of Fish Feed Extruder

fish feed pellet machine
The extension mechanism is divided into 3 segments according to its function and location:

Feeding section: This section has a large screw pitch, mainly for conveying and compressing materials, so that the spiral groove is filled with feed.
Compression section: The screw groove becomes shallower along the feeding direction to compress the material.
Extrusion section: The screw groove is shallow and the pitch gradually decreases.
The outlet of the extrusion section is a pattern, and the shape of the pattern can be designed into holes of various shapes according to the needs of different power sources. As the raw materials is squeezed out of the holes of the die and into the atmosphere, its temperature and pressure drop, causing a rapid increase in volume and rapid evaporation of dehydrated water, turning the materials into puffed extruded pellets for fish or pets.

How Fish Feed Extruder Works

The raw material is evenly fed into the screw extrusion chamber of the fish food extruder by the feeder, and the volume of the extrusion chamber is gradually reduced in the direction of material flow, and the expansion pressure of the material is gradually increased. In this case, the movement of the material in the extrusion chamber is accompanied by strong shear and friction.

Sometimes, depending on the need, an electric heating sheet can be added on the outside of the expansion chamber to facilitate heating. This combined action will cause the temperature of the material to rise sharply and the starch in the material to gelatinize.

By the time the material came out of the mold hole, the pressure suddenly dropped to 0.1 MPa, the water quickly turned into steam and its volume increased, so the volume of the material also increased. The steam is further released and reduces the moisture content of the material, and the temperature drops rapidly. The material then solidifies immediately and forms many micropores in the condensed colloidal material.

Continuously extruded columnar or flaky air products are cut with a rotary cutter and cooled, sometimes post-drying and spraying procedures of additives (such as fat, vitamins, etc.) are also necessary.

Advantages of Fish Feed Making Machine for Producing Extruded or Pelleted Feed

Compared with ordinary feed pellets, the feed pellets produced by RICHI fish feed pellet making machine have the following advantages:

The palatability of the feed improves.
By extruding feed raw materials, the flavor of the feed is enhanced and the palatability is improved, which can stimulate the fish's appetite.
Increases the digestibility of food.
After the feed is extruded and expanded, the long chain structure of protein, fat and other organic compounds becomes short chain, so it becomes more digestible.
High in protein and low in carbohydrates.
The protein content in livestock feed is often less than 20% and in aquafeed is always 30-40%.

Improves the hygienic quality of feed.
Extrusion also reduces bacteria, mold and fungi in the feed raw materials, improves the hygienic quality of the feed, provides sterilized and cured feed for the animal body, thereby reducing the risk of animal disease.
