Title:
PARTICULATE MATTER DRYING METHOD, AND METHOD FOR MANUFACTURING DRYING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/203974
Kind Code:
A1
Abstract:
In order to provide a drying method for achieving an ideal fluidized state of processed material and for performing continuous processing under reduced pressure, with which a high drying efficiency can be achieved, in this particulate matter drying method a median diameter (D50) of particulate matter raw material being processed lies in a range of 1 μm to 1000 μm, and under a reduced pressure of absolute pressure 4 to 30 kPa the particulate matter raw material is fluidized and dried by being heated using a heat medium at a temperature 15 to 120°C higher than the boiling point of a solvent in the particulate matter raw material under said reduced pressure.
