Automated Sand-Roasting Cracker Machine (Oil-Free)
Traditional Oil-Free Cracker Roasting with Automated Rotating Drum
The automated sand-roasting cracker machine mechanizes the production of traditional oil-free sand-roasted crackers (popularly known as kerupuk melarat or kerupuk pasir) without cooking oil. Utilizing a continuous rotating drum heated by high-efficiency gas burners or biomass furnaces, culinary sand is heated to flash-expand raw cracker chips in seconds.
Design Philosophy & Operational Performance
Every machine is designed to resolve common bottlenecks in cracker manufacturing: inconsistent mixing, thickness deviations, irregular steam gelatinization, and high energy costs.
The automated sand-roasting cracker machine mechanizes the production of traditional oil-free sand-roasted crackers (popularly known as kerupuk melarat or kerupuk pasir) without cooking oil. Utilizing a continuous rotating drum heated by high-efficiency gas burners or biomass furnaces, culinary sand is heated to flash-expand raw cracker chips in seconds.
At the discharge chute, an integrated rotary sand separator cleanly sifts heated sand from the expanded crackers, returning the thermal media into the drum while delivering clean, oil-free, crunchy crackers ready for consumption.
