DRYING CHAMBER WITH TEMPERATURE CONTROLLED FAR INFRARED RADIATION HEATER AND SEPARATE AIR SUPPLY AND EXHAUST FANS WITH CHAMBER AT REDUCED PRESSURE

摘要

A far infrared radiation heater (33) is disposed on the back of a ceiling (11a) of a drying chamber (11). The inside of the drying chamber is evenly heated by the heat emitted from the far infrared radiation heater. The drying chamber is provided with air charge means (16) and air exhaust means (17) each communicating with the inside thereof. Outside air is introduced into the drying chamber by means of the air charge means. The air exhaust means continuously maintains the inside of the drying chamber in a state of reduced pressure. Objects to be dried which are placed in the drying chamber are dried by heating under reduced pressure while continuously introducing fresh air. IMAGE
