How About Feed Made by a floating fish feed pellet extruder machine?

Extrusion technology enhances nutrient conversion and improves digestibility and absorption. During operation, the small floating fish feed pellet extruder operates at a high temperature of 120-160℃ and a high pressure of 3-6MPa, rapidly gelatinizing the starch in the raw materials (gelatinization degree exceeding 80%). The restructured starch molecules are more easily broken down and absorbed by the intestines of farmed animals. Simultaneously, it promotes protein denaturation, breaking down anti-nutritional factors such as trypsin inhibitors, increasing the crude protein digestibility and absorption rate by 20%-30%. For example, after processing aquatic feed, the absorption efficiency of nutrients by fish increases from about 65% with traditional feed to over 85%, and in livestock and poultry feed, the feed conversion ratio can be reduced by 0.2-0.3, significantly reducing nutrient waste.

Techniques for balancing the retention of heat-sensitive nutrients. While high-temperature conditions optimize nutrient conversion, they can easily lead to the loss of heat-sensitive components such as vitamins and probiotics. To address this, a wet extruder can be used to control the temperature at 80-100℃, or a "post-addition" process can be employed, adding heat-sensitive ingredients after extrusion and cooling to increase nutrient retention to over 85%. If uneven feed nutrition or slow animal growth occurs, the extruder parameters need to be checked: excessively high temperatures can lead to nutrient loss, while excessively low temperatures result in insufficient starch gelatinization. The temperature needs to be adjusted to the appropriate range, and the uniformity of raw material mixing should be checked to avoid localized nutrient excess or deficiency.

The sterilization and disinfection advantages ensure feed safety. The high-temperature, high-pressure operation of the floating fish feed pellet making machine can simultaneously achieve sterilization, achieving a kill rate of over 90% against harmful microorganisms such as E. coli and Aspergillus flavus. This eliminates the need for large amounts of preservatives, reducing the incidence of disease in farmed animals. If feed becomes moldy or farmed animals experience frequent diarrhea, the temperature and pressure parameters of the extruder need to be checked to ensure they are within acceptable limits, or if there is residual charred material contaminating the feed in the die. Regularly cleaning the internal components of the equipment is necessary to ensure both sterilization effectiveness and feed safety.
