Roasting & Grill Marking

Bigtem Flame Roasting & Grill Marking Lines

Bigtem Flame Roasting & Grill Marking Lines are continuous, industrial roasting systems engineered to deliver consistent fire-roasted flavor, controlled surface blistering, and repeatable grill marks for value-added vegetable and prepared-food products. Product is conveyed through an insulated roasting tunnel on a high-temperature stainless steel rod conveyor designed for extreme thermal exposure (up to 700°C at the product zone), while Bigtem’s precision gas/air mixing burners maintain a stable blue flame for uniform heat distribution across the belt width. Integrated combustion air blowers, automatic ignition, and flame-safety interlocks (“no flame–no gas”) support reliable operation and industrial safety requirements. The entire system is built for hygienic food processing with stainless steel construction and washdown-friendly design, making it ideal for processors producing roasted peppers, eggplant (aubergine), onions for flame peeling, and other roasted vegetable applications at industrial throughput.

For industrial grill marking, Bigtem systems control surface contact time, burner zoning, and conveyor speed to create consistent, high-contrast grill marks without overcooking the product core—critical for retail and foodservice specifications. The grill marking and roasting line can be configured as a standalone roaster or integrated into a turnkey processing line with upstream washing/sorting and downstream cooling, peeling/cleaning, IQF freezing, or packaging. This modular architecture enables processors to scale capacity, improve yield (less over-roast and trim loss), and standardize product appearance and sensory quality across shifts. If you’re evaluating an industrial vegetable roaster, flame peeling roaster, or grill marking machine, Bigtem’s tunnel roasting platform offers a cost-effective path to consistent roasting performance with controllable energy use and repeatable results for premium “fire-roasted” SKUs.
