Feeding → Pre-conditioning → Extruding → Core Filling → Forming → Drying → Coating → Cooling → Finished Nuggets
Raw materials including flour, meat powder, and fat are fed into the screw feeder. The pre-conditioner prepares ingredients with steam and water for optimal extrusion and texture.
The extruder shapes the base material while the core filler injects meat gravy or filling into the center. This creates the unique filled nugget structure with a flavorful core.
The nuggets former cuts filled material into uniform nuggets. The dryer removes moisture for proper texture and shelf life. The coating drum applies fats, flavors, and nutrients. Finally, the cooling conveyor ensures proper temperature before packaging.
