The food puffing machine is composed of many components, and sometimes, improper operation of the machine may lead to some malfunctions. In such cases, the correct operation steps for the food puffing machine become particularly important. Next, let's take a specific look at the correct operation steps for the food puffing machine:
One potential cause for the inability to produce shaped products during the initial operation of a food puffing machine is an excessively high nozzle temperature. This can be due to overly dry raw materials, foreign objects in the spiral groove, or a break in the feeding process. The cause should be identified based on the specific situation.
Troubleshooting: After stopping the feeding, allow the machine to run empty for one minute to exhaust the material inside. Then, shut down the machine. While still warm, remove the nozzle and spiral sleeve, flush out the spiral shaft, clear any remaining residue from the extruder, and clear the nozzle holes for future use.
Prior to operation, the food puffing machine requires the removal of components such as the head, core, and screw rod. Thoroughly clean the core and screw rod of rice residue and oil stains, then dry and reassemble. Start and run for 1 to 2 minutes.
Gradually add the raw materials to the feed port, stopping when approximately a handful fills the annular groove at the spiral shaft head. Perform friction preheating. Resume feeding once the head temperature rises, the chamber pressure increases, and the nozzle starts to extrude. Since the chamber has not reached normal temperature and pressure at this point, gradually increase the feeding rate slowly.
Three, during the operation of the food puffing machine, to avoid blockage of the spiral groove, the feeding should be continuous and even, and the material should be dry. When the blockage of the spiral groove in the puffing machine is found, do not stop immediately. Instead, run it for a while after stopping the feeding until a burnt smell is detected, then stop the machine.
This prevents the nozzle and spiral shaft sleeve from seizing. In case the nozzle and spiral shaft sleeve seize and cannot be removed, do not forcefully hammer or smash. Instead, remove them from the body, heat them in a fire for a while, and they should come off easily.
