Title: Method for drying wet gel
Inventor: HASHIDA TAKU
IPC: F26B7/00
Filed: 2000-07-14
Abstract: PROBLEM TO BE SOLVED: To solve the problem that time necessary to dry wet gel is long and hydrophobicity is lowered when the wet gel is treated at a high temperature in order to be dried in a short time. SOLUTION: Drying is executed by introducing pressurized gas into a drying chamber from an entrance of the drying chamber and making the gas flow to an exit of the drying chamber to form a pressurized atmosphere. Since temperature and vapor pressure of a liquid held by the wet gel are raised and liquid vapor is efficiently removed by flow of the pressurized gas, drying time is greatly reduced. Even when dried at high temperature, the wet gel can be dried in a short time without losing hydrophobicity by blending the pressurized gas with a hydrophobe.
