In our daily lives, we often encounter or consume expanded food products such as potato chips, popcorn, rice candy, corn sticks, compressed biscuits, and pet food, among others. These products are expanded using a food expander, which increases the volume of the material and alters its internal structure. After expansion, they are processed and shaped. So, how should a food expander be cleaned after shutdown?
1. If a food puffing machine stops due to blockage or jamming, remove the machine head nut while the machine is still warm, then take out the screw and sleeve inside (wear thick gloves if the machine is too hot to prevent burns). Next, burn the material inside with a flame or over a gas stove, then clean it thoroughly. If the machine is stuck due to blockage and cannot be removed, disassemble the front cylinder, place it on the fire, but never use a hammer to敲击 it.
2. If a food puffing machine shuts down normally, it's easy to clean. Just use a wire brush to scrub it clean, and the mold core can be cleaned with a small electric drill. If the shutdown is due to blockage or jamming, remove the machine head nut while it's still hot, and take out the inside screw and sleeve (wear thick gloves if the machine is too hot to prevent burns). Then burn off the material inside with fire or over a gas stove, and clean it thoroughly.
Actually, during the process of making膨化products, food extruders play a crucial role. Therefore, special attention must be given to the cleaning of the food extruder after shutdown.
