1. A drying method comprising the following steps:
- supplying a blow of hot air into first drying machine to dry finally an article to be dried and introducing a blow of hot air exhausted from said first drying machine into said second drying machine to preliminarily dry an article to be dried before final drying;
stopping to supply said blow of hot air into said first drying machine;
supplying a blow of hot air into said second drying machine to dry finally said preliminarily dried article to be dried and introducing a blow of hot air exhausted from said second drying machine into the first drying machine to preliminarily dry a new article to be dried before final drying.

Abstract
A drying method, a drying device, and a drying machine, capable of remarkably reducing a drying time by assigning the standby time for an article to be dried to a preliminary drying time in drying, wherein hot air is supplied to the drying machine so as to dry the article to be dried and, at the same time, hot air exhausted from the drying machine is led into a preliminary drying machine so as to preliminarily dry the article to be dried before drying, and then the article to be dried contained in the preliminary drying machine is fed to the drying machine for drying.

2. A drying device comprising:
-
a pair of drying machines, each of them having a rotary drum free to rotate in a chamber, hot air supply means for supplying a blow of hit air into said chamber, and exhaust means for exhausting the interior of said chamber;
exhaust-introducing members, each of them supplying a blow of hot air emitted by said exhaust means from one drying machine to the other drying machine, and from the other drying machine to the one drying machine, respectively;
exhaust switching means being able to select either of a mode to release hot air out into the atmosphere and a mode to supply the hot air to said drying machine, as for the hot air emitted by said exhaust means of either of said drying machines.

3. A drying device comprising:
-
a first drying machine and a second drying machine supplying a blow of hot air to dry an article to be dried;
first exhaust means and second exhaust means included in each of said first drying machine and said second drying machine respectively for exhausting the interior of each drying machine; and
a first exhaust-introducing member for supplying a blow of hot air emitted by said first exhaust means to the second drying machine, and a second exhaust-introducing member for supplying a blow of hot air emitted by said second exhaust means to the first drying machine, wherein;
in case of supplying the blow of hot air emitted by said first exhaust means to said second drying machine, the blow of hot air emitted by said second exhaust means is released out into the atmosphere; and
in case of supplying the blow of hot air emitted by said second exhaust means to said first drying machine, the blow of hot air emitted by said first exhaust means is released out into the atmosphere.

4. A drying device comprising:
-
a drying machine to dry finally an article to be dried;
a preliminary drying machine to dry preliminarily an article to be dried before final drying, the preliminary drying machine being placed in such configuration that a feeding inlet of said drying machine and a discharging outlet of said preliminary drying machine are adjacently located to communicate with each other;
a shutter being provided, free to open or close, between the feeding inlet of said drying machine and the discharging outlet of said preliminary drying machine;
a exhaust-introducing member for introducing a blow of hot air exhausted from said drying machine to said preliminary drying machine; and
a branch pipe for introducing the blow of hot air to said preliminary drying machine, the branch pipe being selectively branched from said exhaust-introducing member, and the branch pipe being introduced into said preliminary drying machine at a position farther distance apart than an introduced position of said exhaust-introducing member from said drying machine, wherein a preliminarily dried article to be dried is transferred to said drying machine through introducing the blow of hot air via said branch pipe by opening said shutter.
