AI Technical Summary
Existing methods for cleaning freeze-drying trays have drawbacks such as uncontrollability, difficulty in ensuring cleaning quality, high labor intensity, low cleaning efficiency, and high labor costs. Furthermore, the cleaning, sterilization, and drying processes for stainless steel freeze-drying trays are complex and have a high possibility of cross-contamination.
A cleaning, sterilization, and drying system with a mobile spray device was designed. It adopts a pipeline system of clean steam, industrial steam, and cold pure water, combined with jacketed auxiliary heating, to realize cleaning, sterilization, and drying in the same sterilization cabinet. The system uses rotating cleaning balls and multi-angle spray rinsing to improve cleaning and sterilization efficiency.
It enables efficient cleaning, sterilization, and drying of large batches of freeze-drying trays, avoiding the risk of contamination from transfer, ensuring cleaning and sterilization effects, improving cleanliness, and making it suitable for the recycling of freeze-drying trays.
