Drying air A with temperature t A (℃), absolute humidity x A (Kg/Kg'), and enthalpy i A (Kcal/Kg')
(A in Fig. 2) is heated with a heater 1 to form hot air B (B in Fig. 2) at a temperature t B and an enthalpy i B , and is blown into the drying material storage 2 by a fan 3. Dry the material to be dried. At this time, since there is no exchange of heat with the outside, the drying air undergoes an isenthalpic change, and as the temperature drops to t C , the absolute humidity rises to x C and becomes warm air C (C in Figure 2). , condenser 4
In other words, it is sent to a heat exchanger. The drying air inside the heat exchanger 4 is supplied by the cooling air D at room temperature outside the machine.
It is cooled to t A and dehumidified to an absolute humidity of x A. Thereafter, it is heated again by the heater 1 and used again to dry the material to be dried. On the other hand, the temperature of the cooling air D is t E
It is heated to a maximum temperature and then ejected from the machine.

大させる方法があるが実用的でなかつた。 In such a conventional dryer, in order to increase the drying speed, it is necessary to lower the absolute humidity of the drying air entering the drying object storage 2 or to increase the temperature. Possible ways to lower absolute humidity include cooling and dehumidifying with a refrigerator, etc., or dehumidifying with a moisture absorbent, but both require extra electricity to operate the refrigerator or regenerate the moisture absorbent, and are extremely expensive. It becomes inefficient. In addition, there is a method of increasing the input to the heater in order to raise the temperature of the drying air, but this is not practical.

The drying air G is reduced to Kg/Kg'' (Fig. 4 F→G). This high-temperature, low-humidity drying air G efficiently dries the items to be dried, such as clothes,
1.4 kg/h of water is evaporated and the isenthalpic change is performed again, returning to point F, and the drying air is circulated (Fig. 4 F→G→F). Since the moisture absorber 6 rotates from 5 to 10 times per hour, the moisture absorbent that has absorbed moisture in the moisture absorption zone 11 is transferred to the regeneration zones 12 and 1 of the moisture absorber 6.

water is drained outside the machine and dehumidified regeneration air J
The air is again blown to the regeneration heater 8 and circulated within the circulation path. On the other hand, air K taken in from outside the machine is sent to the condenser 9.
The air L is heated to 60°C and enters the second regeneration zone 13 at a rate of 35 kg'/h, where it evaporates and regenerates the moisture in the moisture absorbent at a rate of 0.3 kg/h.

For an input of 1032Kcal/h, a moisture evaporation rate of 1.4Kg/h, or drying rate, is obtained, and the latent heat of vaporization is
The drying efficiency is 821 Kcal/h, and the ratio of latent heat of vaporization to input, or drying efficiency, is 821/1032 x 100 = 80%, which is significantly lower than the drying efficiency of conventional hot air drying drum clothes dryers, which is about 65%. Efficiency is high and drying speed can be increased without increasing heater input, or heater input can be reduced for the same drying speed.
