How to solve pellet uneven problem ?
During the pelleting process of the feed pellet machine, the color of individual feed pellets or feed pellets varies among individuals, which is commonly known as "uneven pellet". This kind of situation is more common in the production of aquatic feed. It is mainly manifested in that the color of individual pellets extruded from the ring die is darker or lighter than the color of other normal pellets, or the surface color of individual pellets is inconsistent, which affects the appearance quality of the entire batch of feed.
What should we do if there is problem in the finished feed product?
The main reasons for this phenomenon are as follows:
1. The composition of the feed formula is too complicated, the raw materials are too many varieties, the mixing is not uniform, and the moisture content of the powder is inconsistent before processing the feed pellets.
2.The moisture content of the raw materials used for granulation is inconsistent. In the production process of aquatic feed, in order to make up for the loss of raw material moisture after ultrafine pulverization, we need add a certain water to the mixer, and then enter the conditioner for conditioning after mixing. Some feed manufacturers have simpler processes, and pour water into the mixer directly instead of spraying them evenly with a special nozzle. This makes it difficult to distribute the water evenly after the feed is mixed. When this mixed raw material enters the conditioner for conditioning, it is impossible for the conditioner to further distribute the water evenly in a short time. Under the action of steam, the maturation effect of each part of the feed is inconsistent after conditioning and the pelleting by fish feed extruder machine ,The color changes are also inconsistent afterwards.
3.Recycled materials with re-replicated granules in the granulation bin to be pelleted. The pelleted granules can be cooled and sieved before they become finished materials. The fine powder or small granular materials after sieving will often enter the process flow for re-pelleting, usually into the animal feed mixer or the silo to be granulated. Because this kind of feed is re-conditioned and pelletized, if it is mixed with other raw materials unevenly or mixed with small particles after conditioning, some feed formulas will be uneven.
