Bigtem Flame Roasting & Grill Marking Lines

Industrial flame roasting is a proven thermal processing method used to produce authentic fire-roasted vegetables with consistent blistering, caramelization, and peel performance. Bigtem Flame Roasting & Grill Marking Lines are engineered for continuous, high-temperature vegetable processing, delivering uniform roasting results while maintaining industrial hygiene and operational efficiency.

These systems are designed for processors producing roasted peppers, eggplant (aubergine), onions, zucchini, and other value-added vegetable products for retail, foodservice, IQF, and ready-meal applications.

An industrial flame roaster is a continuous tunnel system that exposes vegetables to controlled direct flame at high temperatures. The process achieves:

• Surface blistering for flame peeling
• Controlled charring and caramelization
• Signature fire-roasted flavor development
• Premium grill marking for value-added products

Unlike batch roasting methods, tunnel flame roasters provide repeatable thermal exposure, consistent residence time, and scalable throughput for industrial production environments.

Bigtem Flame Roasting & Grill Marking Lines use precision gas-air mixed burners to maintain stable blue flame and uniform heat distribution across the conveyor width. Products are transported through the insulated roasting tunnel on a high-temperature stainless steel rod conveyor capable of withstanding extreme thermal conditions.

Core system features include:

• High-temperature stainless steel rod conveyor
• Optimized gas/air mixing burners for uniform flame stability
• Automatic ignition system with flame safety interlock (no flame – no gas)
• High-capacity combustion air blower
• Insulated roasting tunnel for thermal efficiency
• Hygienic AISI 304 stainless steel construction

This configuration ensures even roasting, efficient blistering, and consistent surface treatment across all product types.

Balanced burner positioning and controlled airflow minimize hot and cold spots, ensuring consistent product appearance and roast level.

For applications such as peppers and onions, proper blister formation enhances downstream peeling performance and reduces yield loss.

Tunnel configuration allows steady production flow, higher throughput, and better integration with automated upstream and downstream equipment.

Full stainless steel design supports washdown procedures and modern food safety requirements.

Bigtem roasters integrate with:

• Vegetable washing systems
• Cooling and peeling equipment
• IQF freezing tunnels
• Sorting and inspection systems
• Packaging lines

Bigtem Flame Roasting & Grill Marking Lines are widely used for:

• Roasted red peppers (whole or sliced)
• Flame-peeled tomatoes and onions
• Roasted eggplant for dips and spreads
• Char-grilled zucchini and mixed vegetables
• Fire-roasted components for frozen meals

These systems are ideal for processors supplying private label retail brands, foodservice distributors, and prepared food manufacturers.

When evaluating a vegetable roasting line, processors should consider:

• Target throughput (kg/hr or lb/hr)
• Product type and size distribution
• Desired roast level (light blister vs. heavy char)
• Utility availability (natural gas, air supply, exhaust capacity)
• Integration requirements with peeling or freezing lines
• Available floor space and plant layout

Proper system sizing ensures optimal energy efficiency, product consistency, and return on investment.

Demand for fire-roasted vegetables continues to expand across retail, foodservice, and frozen food sectors. Consumers increasingly prefer authentic roasted flavor profiles, while processors seek automation to reduce labor and improve yield.

Industrial flame roasting equipment enables:

• Labor reduction
• Higher product consistency
• Improved peeling yield
• Premium product positioning
• Scalable production capacity

For processors upgrading existing roasting systems or building new vegetable processing facilities, flame roasting technology is a strategic investment in both product quality and operational efficiency.

Bigtem Flame Roasting & Grill Marking Lines deliver high-temperature precision, hygienic industrial design, and scalable automation for modern vegetable processors. By combining controlled flame exposure with continuous tunnel operation, these systems provide consistent roasting performance, improved downstream efficiency, and strong commercial value.

If you are planning to expand roasted vegetable production or modernize your processing line, selecting the right industrial flame roasting system is a critical step toward long-term profitability and product differentiation.
