The leather product 700 being transferred to the interior drying chamber 110 is dried while the coating surface of the leather product 700 is evaporated by the heat generated from the far-infrared heat source 300.

When the painted surface of the leather product 700 is dried by the heat of the far-infrared heat source 300, moisture is generated in the drying chamber 110 by evaporation heat so that the heat does not fall into the leather product 700. Is discharged to the discharge duct (410).

In addition, the heat discharged through the discharge duct 410 is introduced into the circulation duct 420 according to the operation of the blower fan 430, and the heat introduced into the circulation duct 420 is transferred to the drying chamber 110. It is supplied to the heat source supply chamber 120 is separated by the heat transfer unit (500).

As such, the heat circulated and supplied to the heat source supply chamber 120 is transferred to the heat transfer part 500, and the heat transferred to the heat transfer part 500 is again transferred into the drying chamber 110.

In this case, since the heat transfer part 500 is formed of a metal material having high heat transfer efficiency such as an iron plate or an aluminum plate, heat transferred to the heat transfer part 500 is easily transferred to the drying chamber 110.

Accordingly, as the heat circulated and supplied to the heat source supply chamber 120 is transferred to the drying chamber 110 through the heat transfer part 500, the upper and lower parts of the drying chamber 110 may maintain a uniform temperature as a whole.

Thus, the leather product transported along the transfer part 200 in the drying chamber 110 by heat generated in the far-infrared heat source unit 300 and heat circulated to the heat source supply chamber 120 and transferred back to the drying chamber 110 ( The upper and lower surfaces of 700) are evenly dried throughout.

The reason why the temperature difference between the surface of the transfer part and the leather surface occurs is due to the moisture of the coating film on the leather surface and the thickness of the leather itself. Particularly, the large temperature difference in the leather dryer 10 according to the present invention means that the temperature of the leather surface is large. To prove high. Therefore, it can be seen that the leather dryer 10 according to the present invention has excellent drying speed and drying efficiency as shown in FIG. 6E since the temperature inside the body 100 and the temperature of the leather surface are higher than those of the conventional dryer. In particular, when the reference temperature of the existing dryer and the leather dryer 10 according to the present invention is set to the same, for example, when the reference temperature is set to 140 ℃, the surface temperature of the leather of the existing dryer is 85 ℃, in the present invention The leather surface temperature of the leather dryer 10 according to the present invention is 115 ° C, and the reference temperature of the leather dryer according to the present invention may be 100 ° C in order to equalize the temperature of the leather surface to 85 ° C.
