Effects of the present invention configured as described above are as follows.

First, in order to operate the present invention dryer, a drying plate 22 containing dry matters such as herbs or agricultural products is loaded on each rotary frame, and then a heat source, that is, a petroleum burner 6, in the heat generating furnace 7 is ignited and driven. The motor 13 is driven to interlock the rotary shaft 10 and each of the rotary frames 16a, 16b, 16c, ... 16e, and at the same time blows the heat in the array chamber 8 heated by the heat generating furnace 7. The fan 33 is blown to the upper drying chamber 5 so as to heat and dry the dry matter contained in the drying chamber 5. Thus, part of the hot air rising from the array chamber 8, that is, the array chamber 8. The hot air rising from the upper periphery of the () is hit by the bottom of the lowest rotary frame 16a, dispersed in the outward direction along the bottom of the rotary frame 16a, and then raised along the inner circumferential wall of the drying chamber 5, and also arranged. Hot air rising from the center of the seal 8 causes the central hot air bubble 23 of the lowermost rotating frame 16a to break. As it rises through it, part of it again disperses outward.

In addition, the hot air which has risen and reached the bottom of the rotating frame 16c in the middle portion through the hot air passage 23 of the upper rotating frame 16b is moved toward the outside by the diaphragm 24 blocking the central hot passage. The hot air flows to the inner circumferential wall of the drying chamber 5 and flows to the outer periphery of the intermediate layer rotating frame 16c after the upper and lower parts of each of the rotating frames 16a, 16b and 16c are rotated inward and outward. The path is converted into the inner side by the guide plate 26 of the drying chamber 5 to be concentrated in the center of the rotating frame 16d, and then passes through the heat passage 23 of the rotating frame 16d. The upper wall of the drying chamber 5 along the upper inner circumferential wall of the drying chamber 5 is reached at the same time as reaching the rotating frame 16e of the uppermost part sealed by the fixing diaphragm 24 '. 3), the hot air blown from the lower arrangement chamber 8 as described above is several rotary frames 16a, 1 6b, 16c,... 16e) hot stove, that is, between each layer. By sequentially recirculating to the outside, the dry matters of the drying plate 22 loaded on each of the rotary frames 16a, 16b, 16c, ... 16e can be heated and dried evenly, and the image of the drying chamber 5. It is possible to perform a uniform heating and drying action over the entire interior of the drying chamber 5 without a temperature difference in the lower part, and in addition to the rotating frame 16a in which the drying plate 22 is placed in parallel with the circulation action of the hot air. 16b, 16c,... 16e) rotate, thereby rapidly releasing water vapor evaporated upon drying of the product to promote its drying, and at the same time, turning the heat inside the rising drying chamber 5 laterally. By having it will be able to further improve the drying efficiency.

It is possible to accelerate the steaming of the dry matter and to shorten the drying time and to preserve the original ingredients of the dry matter as much as possible.

On the other hand, if the dry object to be dried is of the type that requires only dry heat, the operation section 31 is adjusted in the reverse direction to close the recovery pipe 28 and open the exhaust pipe 27 to open the drying chamber 5. The internal humid air is discharged into the atmosphere, and only the drying heat heated in the heat storage chamber 4 is circulated and supplied to the lower arrangement chamber 8, so that the drying efficiency of the dry object requiring only drying can be greatly improved. Will be.

In addition, the phase of the drying chamber (5) during the drying operation as described above. On top of drying chamber 5 as thermometers 36 and 36 'attached underneath. Check the temperature of the lower part from time to time in the drying chamber (5). When the temperature difference between the lower part occurs or the temperature inside thereof rises above the proper temperature, most of the lower part is opened by opening the diaphragm 24 which seals off the heat passage 23 of the intermediate layer rotary frame 16c. The temperature of the interior of the drying chamber 5 can be adjusted appropriately by allowing the hot air of the gas to rise immediately, and the drying chamber is controlled in parallel with the opening / closing control of the air inlets 34 and 34 'installed in the heat transmitting pipes 32 and 32'.
