What precautions should be taken when using an animal feed extruder machine to process high-calcium raw materials?

1. Before starting the machine: First, check the mold of the small electric fish feed extruder machine for cracks. Shrimp feed is extruded at high pressure, and a cracked mold is prone to breaking during operation, causing raw material to splash and injure people. Replace the mold immediately if cracks are found. Next, check the screw for wear. High-calcium raw materials will accelerate screw wear, and a severely worn screw can easily jam, affecting the machine's safe operation. Wear protective equipment before operation, including a safety helmet, heat-resistant gloves, and non-slip shoes. Since there are many raw materials piled up in the shrimp feed workshop, comprehensive protection is essential.

2. During operation: Do not open the pressure valve or safety shield while the pet food extruder is running. Under high pressure, raw materials may spray out from gaps, causing personal injury. When feeding, ensure that the raw materials do not contain hard particles (such as uncrushed shells or pebbles). Hard particles can cause jamming and even damage the screw and mold. Always sieve the raw materials before feeding. If parameters need to be adjusted, adjust them slowly while the machine is running smoothly. Avoid sudden and drastic changes in temperature or pressure to prevent machine overload.

3. After shutdown: Safe cleaning without hidden dangers: After shutting down, the power must be disconnected first. Wait for the pressure to fully release and the machine to stop completely before cleaning. Wear thick gloves when cleaning the molds. High-calcium material residue is hard; do not use excessive force during cleaning to avoid the molds slipping and injuring your feet or hands. The machine's pressure pipes should be inspected regularly for aging or leaks. Repair or replace any faulty parts promptly to prevent high-pressure leaks during future use.
