Solution Overview

Problem

Conventional vacuum cleaning devices face challenges in shortening the drying time of workpieces due to inadequate condensation performance in the drying chamber, which hinders productivity improvements.

Innovation Solution

A condenser with a cooling pipe spirally wound to face the steam intake opening, combined with a dual-shell structure and vertically extending fins, enhances coolant circulation and surface area for efficient steam condensation, maintaining the drying chamber temperature lower than the cleaning chamber temperature.
