ABSTRACT:
A far infrared radiation heater 33 is disposed on the back of a ceiling of a drying chamber 11. The inside of the drying chamber 11 is evenly heated by the heat emitted from the far infrared radiation heater 33. The drying chamber 11 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 11 by means of the air charge means 16. On the other hand, the air exhaust means 17 continuously maintains the inside of the drying chamber 11 in a state of reduced pressure. Thus, objects to be dried which are placed in the drying chamber are dried by heating under reduced pressure while continuously introducing fresh air. Therefore, the present invention provides a system for drying objects to be dried whereby not only can dried products be produced within a short period of time but also the flavor is satisfactorily retained in the dried products.
