Precise temperature control is crucial for small fish food pellet making machines. Temperature is the core factor ensuring starch gelatinization and extrusion molding, and it needs to be adjusted according to the feed type: When producing floating aquatic feed, the temperature should be controlled at 130-160℃ to ensure full starch gelatinization, forming a stable porous structure with a buoyancy rate of over 95%; when producing hard pellet feed for livestock and poultry, the temperature can be lowered to 120-140℃ to avoid over-expansion leading to insufficient pellet hardness; when producing heat-sensitive feed (containing probiotics and vitamins), a wet extruder should be used, with the temperature controlled at 80-100℃ to maximize nutrient retention. Excessive temperature can easily lead to pellet scorching and nutrient loss, while insufficient temperature results in incomplete extrusion, causing pellets to sink and have poor digestibility.

The coordinated matching of pressure and speed is also essential. Pressure needs to be adjusted in conjunction with temperature and speed, typically maintained at 3-6 MPa. Insufficient pressure leads to insufficient water vapor expansion and excessively high pellet density; excessive pressure can easily cause die blockage and equipment overload. The screw speed of a floating fish feed pellet extruder machine directly affects the residence time of the raw material in the extrusion chamber. A faster speed results in a shorter residence time, lower expansion, and higher pellet hardness; conversely, a slower speed leads to a longer residence time, higher expansion, and looser pellets. When producing feed for young animals such as fish fry and piglets, reducing the speed and increasing the temperature makes the pellets looser; when producing adult feed, increasing the speed and fine-tuning the pressure enhances pellet hardness and water resistance.

Adapting and adjusting the die parameters of the fish food production machine is also crucial. The die orifice diameter determines the pellet size and must be selected according to the size of the farmed animals (1-2mm for fish fry, 3-5mm for adult fish, and 2-8mm for livestock and poultry). Simultaneously, adjusting the die thickness and cutter speed controls the pellet length (usually 1.5-2 times the pellet diameter). An excessively large die orifice diameter can lead to uneven porosity, affecting buoyancy and stability; an excessively small diameter results in excessive pressure, increased energy consumption, and increased clogging. Furthermore, regularly cleaning residual raw material from the die is essential to prevent charred substances from affecting the quality of subsequent pellets.
