Commercial Roller Hot Dog Grill Machine Product Features 1. Independent Dual Temperature Control System Supports wide temperature adjustment from 20°C to 300°C with grouped heating control. The front and rear heating zones can be regulated separately. Once reaching the preset temperature, the machine automatically pauses heating to maintain the perfect taste of sausages. Multiple heating modes are available to meet different cooking demands. 2. Dual-layer Design with Extra Storage Shelf Equipped with a sturdy upper food rack, forming a double-layer large-capacity structure. Sausages can be cooked on the bottom rolling rollers, while more food can be stored on the upper shelf. The reinforced shelf bears heavy weight and resists bending, greatly expanding food placement space.
