How To Use The Feed Pellet Machine Correctly

How to use the feed pellet machine correctly?

1. The produced particles bent and cracked?

Reason: This situation is often caused by the particles leaving the machine. When the position of the cutter is adjusted farther from the surface and the knife edge is dull, the particles are broken or torn by the cutter instead of being extruded from the die hole. Cut off, at this time some pellets are bent to one side and many cracks appear on the other side. During the process of entering the cooler for cooling or transportation, the pellets tend to break from these cracks, resulting in too much pellet powder produced.

Improvement methods: 1. Increase the compression ratio of the mold, thereby increasing the density and hardness of the pellets.

 2. Pulverize the raw materials more finely, increase the density of pellets, and prevent the feed from being soft.

 3. Adjust the distance between the cutter and the surface of the mold or replace the cutter with a sharper one.

2. Is the surface of the pellets uneven?

This situation is that the powder used for granulation contains raw materials with large particles that have not been crushed or semi-crushed. Due to insufficient softening during the conditioning process, the particles are relatively hard and relatively large. After passing through the mold of the granulator When the pores are not well combined with other raw materials, the particles appear uneven.

Improvement method: properly control the thickness of powdered feed, so that all raw materials can be fully softened during conditioning; for raw materials with more fiber, because steam bubbles are easily mixed, do not add too much to this formula of steam.

3. The color of individual particles or particles is inconsistent?

This situation is common in the production of aquafeed, mainly manifested in that the color of individual pellets extruded from the machine is darker or lighter than that of other normal pellets, or the surface color of a single pellet is inconsistent, thus affecting the appearance quality of the whole batch of feed.

Improvement method: mainly to control the mixing uniformity of each component in the formula and the mixing uniformity of the added water; improve the tempering performance, control the tempering temperature if necessary, and use a lower tempering temperature to reduce the color change; Control the return material. For the formula that is easy to produce "flower material", try not to directly granulate the return material. The returned material should be mixed with the raw material and then smashed again. The mold with guaranteed quality is used to control the smoothness of the die hole. , and the die hole before use if necessary.
