Title:
DRYING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2005/098328
Kind Code:
A1
Abstract:
It has been difficult to operate drying equipment under stable and highly efficient conditions as superheat changes in a drying process. Drying equipment is provided with a first temperature sensor for detecting a temperature of a cooling medium between an outlet port of an evaporator and an inlet port of a compressor, and a control means for controlling a superheat value by changing a flow path resistance value of an expansion valve based on a detection value of the first temperature sensor. Thus, the superheat is controlled at a target value in the drying process.
