Title:
VACUUM DRYING DEVICE
Document Type and Number:
Japanese Patent JP2814424
Kind Code:
B2
Abstract:

PURPOSE: To prevent the trouble caused by incomplete drying, damage to work, etc., and realize a highly accurate drying by a method wherein the drying completion point is monitored within an extremely short time within the allowable range of the heating time applicable to the work, regardless of the amount of water contained in the work and the shape and material quality thereof.
CONSTITUTION: In a vacuum tank 2, a work support jig and/or work holding container 8 and a mounting stand 10 for setting the jig and the work holding container in predetermined positions are all covered with the membrane high in infrared absorption power and resistant to heat and water or made of the material high in infrared absorption power and resistant to heat and water. As a means for detecting the drying condition of the work to be dried in the vacuum tank 2 with a far infrared heater 3, is provided a monitor having a detecting part for continuously measuring the variation of the pressure reduction degree in the vacuum tank at an interval of a predetermined time and a signal detecting part for generating the signal at only the pressure reduction degree higher than the value set in the neighborhood of the pressure reduction degree lower than the target pressure reduction degree.
