Avoiding the segregation of feed ingredients during process of mixing, people use pelleting process to increase gelatinization and digestibility of feed so that fish is more apt to receive a totally mixed nutrition. Just as its name implies, fish feed pelleting refers to the process of compressing, pelleting and molding feed ingredients into the shape of pellets under the action of the heat, moisture and pressure. Pelleted and extruded feed produced by fish feed pellet mill and extruder have become the mainstream feed for most fish because of its high digestibility, abundant nutrition and floating properties.

Pelleting is to process the mixture of feed ingredients under high temperature, moisture and high pressure within fish feed pellet mill - raw materials are pressed through die mold. According to lots of experience, too little or too much steam and heat added to the ingredients would produce pellet with poor quality while insufficient temperature and uneven mixing could not kill the dangerous pathogenic micro-organisms existing in feed pellets. The path to the perfect fish feed pellet requires top processing technology and advanced pellet mill and fish feed extruder. In partnership with the feed industry FANWAY continually strives for pelleting process technology and machine so as to improve the feed conversion rates and nutrition of fish feed. Now let’s discuss the detailed processing of making fish feed pellets.

In general, there are lots of raw materials for making fish feed pellets - from grains to wood and straw, such as corn, bean pulp, straw meal, soybean, peanut cake, rice bran, wheat bran and so forth. Except for producing fish feed, pelleting process also can be applied to produce animal feed(such as livestock and poultry feed), organic fertilizer pellets (with flat die pellet mill) and biomass industries.
