What are the characteristics of feed produced by fish food production machines?

Flexible adjustment of physical properties adapts to all aquaculture scenarios. The floating fish feed pellet making machine can precisely control feed pellet characteristics by adjusting temperature, pressure, screw speed, and die parameters: when producing floating aquatic feed, increasing temperature and pressure creates a uniform porous structure inside the pellets, achieving a buoyancy rate of over 95% and water resistance of 8-12 hours, suitable for mid-to-upper-level fish; when producing sinking feed, reducing the degree of expansion controls the pellet density at 1.1-1.3 g/cm³, suitable for bottom-dwelling fish; for livestock and poultry feed, the hardness can be adjusted to 2-5 kg, balancing chewability and digestibility. If the pellets have poor buoyancy and sink quickly, it is usually due to insufficient temperature or low pressure in the small fish food pellet making machine. This requires increasing the temperature by 5-10℃, adjusting the screw speed to increase pressure, and optimizing the starch content of the raw materials to over 35%.

High quality stability makes storage and transportation more convenient. After high-temperature extrusion and drying/cooling, the feed produced by the floating fish feed pellet extruder machine has a moisture content controlled at 12%-14%. This results in a compact pellet structure that is less prone to moisture absorption and mold growth, extending the shelf life by 1-2 months compared to traditional feeds. Furthermore, the pellets exhibit high uniformity, with a breakage rate of ≤3%, reducing the likelihood of fragmentation during transportation and decreasing feed waste by over 50%. If the pellets are prone to fragmentation or have poor water resistance, the extruder parameters need to be checked: over-extrusion leads to loose pellets, while insufficient pressure results in insufficient compactness. In such cases, the temperature and pressure need to be reduced, and drying parameters adjusted to achieve the required moisture content. If necessary, 1%-2% binder can be added to stabilize the structure.

Key points for ensuring pellet consistency: The small floating fish feed pellet extruder machine's forced feeding and precision cutting device control the pellet diameter and length error within ±0.2mm, avoiding the uneven pelleting problems of traditional pelleted feeds. If there are inconsistent particle sizes or many deformed particles, it is necessary to check whether the extruder die head is worn and whether the cutter speed is appropriate. Replace the worn die head in time, calibrate the cutter parameters, and at the same time ensure that the raw material particle size is uniform (80-100 mesh) to avoid uneven extrusion molding caused by particle size differences.
