Abstract
A high speed negative pressure air stream from a sucking-out nozzle or a combination of a high speed negative pressure air stream from the sucking-out nozzle and a high speed air jet stream from a blowing nozzle are used for drying an article. Flanges can be installed at a tip end of the sucking-out nozzle and the blowing nozzle. The air jet stream can be injected obliquely to the surface of the article to be dried. Water adhered to an article to be dried, for example, a wet mat, is rapidly divided into minute water drops which are extracted. Vermin, lice and other contaminants are also removed. The article to be dried is rapidly dehydrated and dried in a low temperature. The sucking-out nozzle provided with a flange in a sucking-out pipe is placed so that it can slide on the surface of the article to be dried. A water drop separating vessel is installed between the sucking-out pipe and the inlet of a blower. A dehumidifier is installed between the outlet of the blower and the blowing pipe. Thus, air is circulated and continuous drying is performed efficiently, without vaporization heat, within a short amount of time and requiring little energy consumption.
