JPS643488A - Shelf type drier - Google Patents

Abstract

PURPOSE: To enhance a drying efficiency by longitudinally rotatably forming a shelf of a drying chamber, and inclining it at a suitable angle, thereby bringing a hot air into contact with a material to be dried. CONSTITUTION: A shelf 3 of the dryer is supported at centers of both sides by pins 7, and inclined to right or left at the pins 7 as centers. Further, the shelf 3 is coupled, in place, by a rod 8, and the rod 8 is vertically moved to be simultaneously altered at its inclining angles. Drying of a material to be dried is first executed by charging a predetermined amount of the material 12 to be dried in a tray 11 of a drying chamber 1A, setting it to the shelf 3, and coupling the chamber 1A to a hot air supplying unit 2. Then, the unit 2 is started, and drying air of suitable temperature is blown into the chamber 1A. At this time, the shelf 3 of the chamber 1A is, for example, inclined at the right side upward, and the drying air blown from the unit 2 into the chamber 1A is brought into direct contact with the material 12 and dried.
