How to Choose the Right Oven for Bread Production Lines

        In the baking production line, the oven determines yield, energy consumption, and product consistency. In the face of a market with multiple specifications and flavors, companies need to adopt selection methods centered on capacity matching, energy efficiency optimization, and scalability. This article combines the mainstream equipment spectrum and application scenarios of the industry to provide an oven configuration approach suitable for bread factories and central kitchens.

        Ⅰ. First, identify 'which type of oven is suitable for which task.'

        The common types of industrial ovens in the industry fall into four categories:

        1) Rotary Ovens: Frame-based batch production; energy options include electricity, gas, and fuel.

        2) Tunnel Ovens: Sustained high-capacity production, customizable according to process requirements.

        3) Hot Air Convection Ovens: Flexible and quick to update, suitable for multiple SKU, small batches, and store/prototype scenarios.

        4) Layered Ovens: Multi-layer independent temperature control, suitable for products like European bread and pizza.

        Key Considerations: Use rotary ovens for medium batch stability, tunnel ovens for large-scale throughput, layered ovens to enhance the upper limit of specialty bread, and convection ovens to support prototyping and rapid iteration.

        Ⅱ.Transform selection into quantifiable 'equations'

        1) Production capacity matching: Calculate based on 'target hourly output → quantity per tray → number of trays/cars or bandwidth → cycle time'.

        2) Energy efficiency and uniformity: Focus on unit energy consumption per finished product and temperature/difference, prioritizing solutions with heat recovery, variable frequency fans, and zonal temperature control.

        3) Humidity and hardness curves: Steam volume, moisture removal, and airflow switching determine the surface and interior; prioritize programmable process curve control.

        4) Cleaning and maintenance: The durability of quick-release ducts, door seals, and observation windows directly affects downtime; standardization of parts facilitates spare parts and maintenance.

        5) Process compatibility: Match cycle times with proofing, cooling, slicing/packaging processes to avoid 'fast at the front, slow at the back' reliance on manual adjustments.

        Ⅲ. Application scenario examples

        Central factory expansion: Mainline uses tunnel furnaces for large-scale chassis production,while rotary furnaces handle off-peak and custom orders at different times.

        Multi-SKU brands: A combination of stratified and convection furnaces quickly validates new products, which are then integrated into the mainline equipment using standard curves.

        Retail stores/small factories: Prioritize convection or small rotary furnaces to enhance space efficiency and quick switching.

        AOCNO recommends following a path of type selection→parameter quantification→system validation for investment decisions, ensuring consistency while incorporating energy consumption and maintenance costs into lifecycle considerations. A one-to-one configuration plan and energy consumption calculation need to be provided based on existing facilities, SKUs, and growth curves.
