About the Working Principle of the Smokeless Grill

The core working principle of the Smokeless Grill lies in "smoke isolation technology" and "smoke and oil recovery technology." Through a special structural design and power system, it changes the traditional method of direct charcoal grilling, effectively eliminating the generation of harmful smoke.

1. Smoke Isolation Technology:

High-temperature radiant heat cooking: The product uses a built-in invisible charcoal tray design, where the charcoal is located in a hidden compartment below the grilling chamber, separating it from the food. Cooking is achieved using the high-temperature radiant heat from the charcoal.
Complete fuel combustion: Through the designed air intake and combustion-aiding devices, the charcoal burns completely at high temperatures (usually above 750℃), avoiding the emission of smoke and harmful gases caused by incomplete combustion.

2. Smoke and Oil Recovery Technology:

Dual-chamber structure design: The product uses a dual-chamber furnace design with a drip tray (or oil pan). When grease or seasonings from the food drip into the drip tray, the absorption effect of water or oil separates the grease from the charcoal, preventing the grease from dripping into the charcoal and producing smoke.
Water-filled drip tray: Some models have a water-filling device built into the drip tray. When the grease comes into contact with the water, it is diluted or decomposed, further reducing smoke generation.

3. Auxiliary Power System:

Blower device: A dedicated blower device (dual-engine power fan) provides powerful airflow to ensure complete combustion of the charcoal, and simultaneously uses jet air curtain technology to blow the smoke away from the food surface.
Automatic flipping function: Some high-end models (such as smokeless barbecue machines) are equipped with a low-voltage motor drive to automatically flip the meat, preventing grease from dripping into the fire and thus achieving smokeless grilling.
