Equipment-related faults and troubleshooting: 1. Floating fish feed pellet making machine die blockage, manifested as a sudden pressure increase and interrupted discharge, often caused by uneven raw material particle size, excessive moisture, or residual charred material in the die. Solution: Immediately stop the machine, turn off the power and steam, disassemble the die, clean the residual raw material with a special tool, and check if the raw material grinding and moisture content meet standards. Adjust and restart production. 2. Screw jamming, often caused by impurities in the raw material or excessively fast feeding leading to overload of the small floating fish feed pellet extruder machine. Solution: Stop feeding, disconnect the power, disassemble the barrel to clean residual material and impurities from the screw, check if the lubrication system is normal, and subsequently strengthen raw material screening and feeding speed control. 3. Equipment vibration and abnormal noise, possibly due to excessive screw clearance, loose anchor bolts, or damaged bearings. Stop the machine, check and tighten bolts, replace worn parts, and ensure stable equipment operation.

Pellet quality-related faults and troubleshooting: 1. Poor pellet buoyancy and rapid sinking, often due to insufficient temperature, low pressure, or excessively low starch content. Solutions: 1. Increase puffing temperature by 5-10℃, adjust screw speed to increase pressure, and optimize raw material formula to increase starch content to over 35%. 2. Scorched pellets with poor palatability are often due to excessively high temperature or excessively long raw material residence time. Solutions: Lower temperature, increase screw speed of the small fish food pellet making machine, shorten the residence time of raw material in the extrusion chamber, and clean residual scorched material from the barrel and die. 3. Pellets easily break apart and have poor water resistance, often due to over-puffing, excessive moisture, or insufficient binder. Solutions: Lower temperature and pressure, adjust drying parameters to control the finished product moisture content at 12%-14%, and add 1%-2% food-grade binder to stabilize the pellet structure.

Preventative Maintenance Points Regularly check the wear of the core components (screw, barrel, and die head) of the floating fish feed pellet extruder machine. Replace them promptly if the wear is severe to avoid affecting the extrusion effect. Regularly clean the residual raw materials inside the equipment to prevent mold from contaminating subsequent feed. The lubrication system needs to be regularly lubricated with special lubricating oil to ensure smooth operation of the components, reduce the failure rate, and extend the service life of the equipment.
