Case Study: Automatic Installation for Multi-deck ovens

Automatic Vacuum Cleaning System for Multi-deck Ovens: our Case Study

Industrial bakeries face strict quality standards to ensure their products meet excellence. Maintaining cleanliness is mandatory in food processing. Employing an industrial vacuum cleaner for ovens enables the simple removal of crumbs, baking residues, and burnt flour, safeguarding against contamination and preserving product quality.

Multi-deck ovens are a staple in industrial bakeries, prized for their versatility in simultaneous production. However, their extensive size poses challenges during cleaning, particularly between batches, making it a time-consuming and intricate task.
