Feeding System: The machine has a hopper where ingredients (like flour, starch, and seasoning) are fed into the extruder.
Extruder Barrel and Screw: Inside the machine, the barrel contains a rotating screw that mixes and kneads the ingredients. The screws rotation applies pressure and heat to the mixture, causing it to cook and expand.
Die Head: The extruded mixture is forced through a die head, which shapes the dough into various forms (e.g., rings, stars, or other shapes).
Cutting System: After exiting the die head, the extrudate is cut into desired lengths by a cutting mechanism.
Cooling System: The fried or baked fryums are cooled to harden and become crisp.
Frying System: Some machines include an integrated frying unit. Alternatively, the fryums can be fried in a separate fryer after extrusion.
