A bottle washer is a device used to clean both the interior and exterior of bottles, ensuring they meet hygiene standards before filling. The design principle is based on high-pressure water flow and brushing technology, using nozzles and rotating brushes for thorough cleaning. During operation, the bottle washer places bottles on a specialized tray, removing dirt and residues from both inside and outside the bottles with high-pressure water jets and rotating brushes. The equipment may also include a drying system to ensure the bottles dry quickly after cleaning. Bottle washers are widely used in the food, beverage, pharmaceutical, and cosmetic industries, especially on production lines handling large quantities of bottles, providing an efficient and reliable cleaning solution.
