Precise temperature and pressure control ensures efficient retention of nutrients. The Twin Screw Fish Feed Pellet Extruder employs segmented temperature control technology. The barrel is divided into feeding, compression, plasticizing, and forming sections, each with independently adjustable temperatures. For example, the feeding section is controlled at 60-70℃ to prevent premature gelatinization of the raw materials; the plasticizing section is controlled at 110-120℃ to ensure full starch gelatinization; and the forming section is lowered to 90-100℃ to minimize the loss of heat-sensitive nutrients. Comparative tests show that feed produced by the twin-screw extruder retains 85% of vitamin E, compared to only 60% with a single-screw extruder; lysine retention reaches 90%, 18 percentage points higher than single-screw extruders. This effective retention of nutrients directly enhances the nutritional value of the feed.

Good palatability and digestibility are crucial for promoting fish growth. The high-intensity shearing action of the Twin Screw Fish Pellet Making Machine refines the raw material particles to over 100 mesh, increasing the feed's specific surface area, making it easier for fish digestive enzymes to act, and improving digestibility by 20%-30%. Simultaneously, the Maillard reaction generated during extrusion produces flavor compounds that fish find appealing, improving feed palatability and increasing fish feed intake by approximately 15%. A tilapia farming trial showed that feeding tilapia with feed produced by a twin-screw extruder increased daily weight gain from 3g to 4.2g and reduced the feed conversion ratio from 1.8 to 1.3, significantly lowering farming costs.

The physical stability of the feed is also greatly improved. Fish feed produced by a twin-screw extruder has high pellet density and water resistance for over 30 minutes, preventing it from easily disintegrating after soaking in water, reducing feed waste and water pollution. Feed produced by single-screw extruders typically only has water resistance of 10-15 minutes, with some feed dissolving in water before being consumed by fish, resulting in raw material waste and potentially leading to eutrophication and increased fish disease risk. Using a twin-screw extruder reduces feed waste from 10% to below 3%, further lowering raw material costs for fish farmers.

In addition, the high-temperature sterilization function of the twin screw fish feed machine can effectively kill harmful microorganisms such as E. coli and Salmonella in the raw materials, with a sterilization rate of 99%, reducing the probability of intestinal diseases in fish and ensuring the healthy growth of fish.
