Working Principle of the Combined Contact Cooker
During industrial twin grill operation, food is fed by the infeed conveyor system between the upper and lower heated conveyor belts. The heating plates transfer heat to the conveyor belts, which is then conducted by direct contact to the upper and lower surfaces of the food, enabling the product to undergo heating, cooking, and surface browning simultaneously.
The PLC control system coordinates the heating temperature and conveyor speed to regulate the food's dwell time within the equipment; by adjusting the distance between the upper and lower conveyor belts, the system can also accommodate products of varying thicknesses.
After processing is complete, the food is continuously discharged from the outlet and proceeds to subsequent cooling, quick-freezing, or packaging processes.
Common Cooking Challenges in Food Processing
In continuous food processing, traditional heating methods are easily affected by factors such as product thickness, surface moisture, heating time, and equipment design, leading to inconsistent processing quality and production efficiency.
- Uneven Heating of Products:Single-sided heating or hot-air heating can cause temperature differences between the top and bottom surfaces of the product, affecting the degree of cooking and the final texture. This issue is even more pronounced for foods with inconsistent thickness.
- Moisture Loss During Cooking:Prolonged heating can easily cause moisture loss from the interior of the food, resulting in tough, dry meat and a reduction in product weight, which affects yield and economic efficiency.
- Inconsistent Surface Browning:Improper control of heating temperature, contact pressure, and dwell time can easily result in issues such as localized over-browning or insufficient surface browning, which affect product appearance.
- Adhesion of Marinated and Sticky Products:Foods that have been marinated, coated with sauce, or surface-coated are prone to sticking to the conveyor belt during heating, causing product damage, residue buildup, and increased cleaning burdens.
- Insufficient Continuous Production Efficiency:Traditional batch-style cooking requires frequent loading, flipping, and transfer, increasing manual labor and complicating production line integration.
Combined contact cookers help address these issues through direct heat transfer on both sides, continuous conveying, and adjustable process parameters, thereby improving the stability and controllability of the food processing operation.
