Specification 1: High-protein functional feed, suitable for carnivorous/fast-growing fish
The core specifications of this high-protein fish feed are: protein content ≥38%. It can be combined with high-quality protein ingredients such as fishmeal and soybean meal, and is suitable for carnivorous fish such as bass, snakehead, and salmon, or juvenile and medium-sized fish requiring rapid growth. When producing this feed using a twin-screw fish feed extruder, the following parameters need to be optimized: temperature 140-150℃, pressure 5-6MPa, employing high-temperature short-time curing technology to avoid excessive protein denaturation and retain nutritional activity; particle size should be selected from 2mm to 8mm according to the fish's body size, and buoyancy can be flexibly selected as floating (bass) or sinking (snakehead). Actual testing shows that the high-protein feed produced by the twin-screw extruder has a protein digestibility and absorption rate ≥85%, far exceeding that of ordinary pelleting equipment, and can significantly improve the growth rate of fish.
Specification 2: Hypoallergenic Functional Feed, Suitable for Allergic Fish/Fry
The core specifications of this hypoallergenic fish feed are: grain-free and soybean meal-free (allergens only), using pea flour and sweet potato flour instead of grains, and fishmeal and silkworm pupa flour as protein sources. It is suitable for allergic fish or fry (such as carp fry and grass carp fry), reducing issues like skin itching and intestinal discomfort. During the production of the Twin-Screw Sinking Fish Feed Extruder, parameters need to be adjusted: lower the temperature to 120-130℃, the pressure to 4-5MPa, and slow the screw speed to ensure the grain-free feed is fully cooked and forms a stable shape; the particle size should be controlled between 0.8mm and 3mm, with buoyancy primarily floating or semi-sinking, facilitating feeding for fry while avoiding the risk of allergies due to feed residue, complying with the "Safety Limits for Aquatic Feed" standards.
Specification 3: Liver-Protecting/Gallbladder-Promoting Functional Feed, Suitable for Large-Scale Aquaculture
The core specifications of liver-protecting fish feed are: the addition of 0.3%-0.5% bile acids, vitamin C, and other ingredients, suitable for fish raised in long-term, high-density environments (such as tilapia and grass carp), which can protect the liver and gallbladder function of fish and reduce stress response; the growth-promoting feed adds probiotics, enzyme preparations, and other ingredients, which can improve digestibility and absorption rate and accelerate growth. When producing this type of feed using the Twin Screw Dog Food Extruder machine, a "low-temperature extrusion + post-addition" process is required. Heat-sensitive functional ingredients (probiotics, enzyme preparations) are mixed in after extrusion to avoid high temperature destroying their activity; the extruder parameters are controlled at a temperature of 130-140℃, a pressure of 4.5-5.5MPa, a particle size of 2mm-7mm, and buoyancy can be flexibly adjusted according to the aquaculture scenario.
