Frequently Asked Questions (FAQ)
The machine is versatile and can form a wide range of donut styles including classic ring donuts, filled donut shells, elongated Long Johns, and bite-sized donut balls simply by adjusting or swapping forming nozzles and parameters.
The machine utilizes precision-controlled pneumatic pressure combined with adjustable extrusion timers and synchronized cutting blades, ensuring each dough piece has an identical weight, volume, and shape.
The Donut Former/ 6 features 6 units per row with a capacity of 1,200 to 4,800 pcs/h and a 53L hopper, ideal for medium-scale lines. The Donut Former/ 12 doubles the output to 4,800–9,600 pcs/h with a 135L hopper for large-scale industrial output.
Yes. While the standard configuration operates on 3Ph 380V 50Hz, voltage and frequency specifications can be customized (e.g., 220V, 415V, 480V, 60Hz) to match your factory's local power requirements.
The extruder is engineered with standard synchronization interfaces, allowing it to seamlessly align and communicate with automatic proofer conveyors, continuous fryers, glazers, cooling spirals, and packaging systems.
The hopper and extrusion nozzles are constructed from food-grade stainless steel with quick-release fasteners, allowing easy disassembly for thorough sanitation, daily washdowns, and rapid changeovers.
