Laser Cleaning Baking Surfaces Without Damage

The patent replaces the mechanical brushing system with a laser-based cleaning system. The laser beam (optical/energy field) is directed at the baking surfaces to remove deposits without mechanical contact, thereby eliminating surface damage while maintaining cleaning effectiveness. This is achieved through the laser arrangement with movable laser head that can precisely target and clean deposits on the baking plates.

The patent employs parameter changes in the laser radiation (power, pulse duration, wavelength) to achieve effective removal of stubborn deposits while maintaining surface integrity. By adjusting laser parameters such as power density and exposure time, the system can selectively remove incrustations without damaging the underlying baking surface, overcoming the limitation of gentle mechanical methods.

The patent enables continuous cleaning action by integrating the laser cleaning system into the existing production workflow. The laser arrangement can clean baking surfaces during or between production cycles without requiring complete shutdown, allowing for continuous or near-continuous operation. The quick response time of laser cleaning minimizes production interruptions compared to conventional mechanical cleaning methods.

The patent designs the laser cleaning system with universal applicability to handle various types of deposits (oils, fats, starchy deposits, sugar deposits) on different baking surfaces using a single integrated system. The laser arrangement with adjustable parameters can adapt to different cleaning requirements without requiring multiple specialized devices, thereby reducing overall system complexity while maintaining high cleaning performance.
