The dry matter is maintained in chromaticity by the far-infrared projection heat (c) while the dry matter supplied through the screw drying furnace 9 is transferred along the feed screw 7 at the same time as the drive rotation of the screw drying furnace 9, and the water content decreases from the inside to the outside of the dry matter. It is dried as much as possible, and driven by the shape of the device to the structure of the device which is continuously dried and discharged by the rotation rate of the motor 26 and the water content of the dry matter.

At this time, the inlet heating cylinder (1) is equipped with the right side shaft shaft bearing holder fixed valve and the exhaust fan (17) of the exhaust cylinder (15) and the building discharge semi-cylinder (21) are assembled on the right end and the screw drying furnace (9) Drying Furnace Drive shaft shaft 10 is connected to the left and right bearing holders 28 by shaft bearings 14 and 14 ', so that the rotational drive of the screw drying furnace 9 is adjusted according to the type of building. (9) The invention relates to an effective drying apparatus which maintains chromaticity so that moisture is separated from the inside to the outside by the far infrared ray projected heat (c), and the moisture content is uniformly reduced. The energy source of the device is a clean energy saving type that can directly control fossil fuel and electric coil's direct heat to the drying furnace to maintain the temperature control and improve the defect that the drying is not uniformly dried and roasted. . The invention relates to a far infrared ray drying apparatus "with the high frequency induction heating.

The present invention is a heat-resistant material in the induction heating body (1) in which the induction coil (3) is wound so as to heat the induction heat at an appropriate temperature for the heat source of induction heating by the low and high frequency induction coil (3) as shown in FIG. (4) induction heating heat-resistant material (2) enclosed by the outer cylinder (1) to form an induction heating cylinder (1) and induction heating cylinder (1) the inner diameter 1/3 of the pre-molded macsumstone block (5) attached and induction heating The left end of the cylinder (1) is a drying supply cylinder (19) is installed, the left shaft shaft bearing holder fixed shaft and supply cylinder (10 ') with the shaft shaft (10) shaft bearing (14') of the drying furnace of the screw dryer (9) 18) and the right end is the right end shaft shaft bearing holder fixed shaft and the exhaust cylinder (15), and the air blower (17) and the building discharge semi-cylinder (21) are installed. 10) The shaft bearing (14) is provided so that the screw drying furnace (9) is installed at the center of the inner diameter of the induction heating cylinder (1). By the rotation of the driving roller 27 by the surface motor 26, the screw dryer 9 is rotated, and the left outer cylinder of the screw dryer 9 is aligned with the screw dryer so that the left drilling tool 8 is provided. The screw drying furnace side outer cylinder (6) is made of a flat plate, and the drying product supplied from the supply cylinder (19) to the inlet (11) by the screw drying furnace (9) has an inner diameter of the spiral feed screw (7). With the rotation of 9) is transferred toward the building outlet 12, the induction heats the induction heating cylinder (1) at 400 ° C or more from the heating cylinder (1) and then conducts heat to the pulsar stone (5) to heat the far infrared projection (c) is divergently projected to allow drying from the inside of the building

Since the left end shaft shaft bearing holder fixed shaft and supply cylinder 18 with the left supply cylinder 19 are perforated to supply external air (a), the heating gas of the induction heating cylinder 1 becomes a source of heat source, The heating gas (b) heats the screw drying furnace (9) with conductive heat and the latent heat (d) through the inner diameter of the screw drying furnace (9) through the left drilling tool (8) through the screw drying.
