Compare Tunnel Oven Zone Configurations

Give bidders a product and process brief

List the products, dough or batter condition, piece size, target finish, band or tray format and planned line speed. Include the changeovers that matter commercially. A cookie and a bread snack may need different heat and moisture handling even when their planned output is similar.

Tell bidders which products are proven and which are still under development. For each, request the proposed bake-time range and the assumptions about loading, infeed and cooling. These inputs make an oven comparison more useful than a single advertised capacity.

Ask what each zone is meant to do

Reading Bakery Systems describes direct gas-fired, convection and recirculation zones with different ways to apply heat and manage airflow. A zone name is not a universal performance guarantee. Ask the supplier to show where surface colour, moisture removal and final bake are expected along your product path.

Request a layout with zone lengths, exhaust points, utility connections, access doors and the controls available to operators. Check whether the proposed combination fits the building and local gas or electrical services. Keep a separate record of installation responsibilities.

Compare evidence and the limits of the offer

Ask how representative products will be tested and what the supplier will record: settings, belt speed, product position and finished quality. Define the acceptance stage and who supplies ingredients and operators. A test on a different recipe can guide design but cannot prove your product result.

Compare bids against the same scope, including exhaust, band, cleaning access, spare parts and commissioning. Record any proposed future product that has not been trialled. The Reading Bakery Systems source linked below illustrates distinct heat-transfer options.
