A transporting ring, a horizontally moving transporting ring attached with a push plate, a transporting means of the dried substance placing means including a driving means of the transporting ring, and a control means; and moving the dried substance placing means. The dried product is air-dried while circulating.
Above, there is provided means for detecting the movement of the dry matter placing means.
In the above or in the above, a means for detecting the movement of the transport ring is provided. In the above or the above, a hot air circulation means is provided.
The above-mentioned or the hot-air supply means comprises a steam heat exchanger and a blower. the above,,,
Alternatively, a means for sterilizing the dried product is provided. The above sterilizing means is an ultraviolet irradiation device.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS When the drying apparatus constructed as described above is started, the dried product placing means is vertically moved while being held by the push plate, horizontally moved by being pushed by a push plate, and air-dried while being circulated. . When the drying device configured as described above is started, the presence / absence of the dried material placing means is detected. When the drying device configured as described above is started, it is detected that the transport ring has moved a predetermined distance. When the drying device configured as described above is started, the hot air that has passed through is blown again. When the drying device configured as described above is started, heat is conducted to the air from the pipe through which the steam flows, and the hot air is blown by the blower. When the drying device configured as described above is started, the dried product is sterilized. When the drying device configured as above is started,
Ultraviolet rays are applied to the dried product and sterilized.

[0006]

Embodiments will be described with reference to the drawings.
Reference numeral 1 denotes a dried product placing means, which is a plastic mesh container in the present embodiment, but may be any other container or plate-shaped material as long as it has air permeability and heat resistance. . Reference numerals 2 and 3 denote transport rings for vertical movement, which are formed by chains in this embodiment. In the present embodiment, the transport rings 2 and 3 form a set of four, and the two rotating rings 3
0 and 31 are connected. One of the rotating shafts 30 and 31 is driven by motors 34 and 35 to rotate the transport rings 2 and 3. The transport rings 2 and 3 are provided with a plurality of holders 4 and 5 for holding the container 1. The container 1 is supported on the left and right by holders 4 and 5. Reference numerals 6 and 7 denote horizontally moving transport rings, which are constituted by chains in the present embodiment, are formed as a set of two, are connected by rotating shafts 32 and 33, and are driven by motors 36 and 37. doing. The transport rings 6 and 7 are provided with push plates 8 and 9, and the push plates 8 and 9 push and move the container 1 by rotating the transport rings 6 and 7.

[0007] These movements are detected by detecting means,
Controlling. In the present embodiment, in order to confirm the presence of the container 1, a total of four transport rings 2, 3 are provided, one each for the top and bottom containers of the vertically moving transport rings 2, 3, respectively.
2 each for confirming that the plate has moved a certain distance, and 2 each for confirming the movement of the push plates 8 and 4
, Total 10 contact limit switches 10-19
Is provided. The detection means may be another sensor (such as a non-contact type), and the number of sensors is not limited to this.

Reference numeral 21 denotes an outside air inlet. The introduced air is heated by the steam heat exchanger 20, and is blown by the blower 22 from the hot air supply port 23 to the drying chamber 24. The method of generating hot air may be another heat exchanger or a hot air generator. Reference numeral 25 denotes an air circulation path, and the dried air flows to the heat exchanger 20 again. Reference numeral 26 denotes a hot air exhaust port, and by providing a door 27, the amount of exhaust (the amount of circulating air) can be adjusted. Reference numeral 28 denotes an ultraviolet irradiation device, which irradiates the dried material to sterilize the dried material. The means for sterilization may be other than ultraviolet irradiation,
A means for providing a nozzle and spraying a sterilizing solution may be used.

The above-described device is driven. Dried product 29
Is placed in the container 1 and the container 1 is set in the drying chamber 24. At this time, the container 1 is not placed on the lower holder 4 of the transport ring 2 and the upper holder 5 of the transport ring. The steam type heat exchanger 20 and the blower 22 are started to start supplying hot air. By operating the control panel 39, the temperature of the hot air,
Set. The transport ring 3 rotates so that the container 1 moves upward, and the transport ring 2 rotates so that the container 1 moves downward, and starts moving the container 1.

After detecting the limit switches 18 and 19, the transport rings 2 and 3 stop after moving a certain distance. The limit switches 10 and 12 confirm the existence of the container at the bottom of the transportation ring 2 and the transportation pipe 3 at the top, and if the container 1 exists, the transportation rings 6 and 7 for horizontal movement are operated. A push plate 8 provided on the transport ring 6 pushes the container 1 at the top of the transport ring 3 to move it to the top of the transport ring 2. Further, the push plate 9 provided on the transport ring 7 pushes the lowermost container 1 of the transport ring 2 to move it to the bottom of the transport ring 3. The limit switches 11 and 13 detect that the container 1 has been moved to the home position (the limit switches 15 and 17 detect that the push plate has moved a preset distance), and the push plates 8 and 9 are returned to their original positions. Then, the limit switches 14 and 16 confirm that the push plates 8 and 9 have returned. Transport ring 3 is container 1 again
Rotate so as to move upward, and the transport ring 4 rotates so that the container 1 moves downward. If there is no container at the bottom of the transport ring 2 and at the top of the transport ring 3 after the vertical movement, the push plates 8 and 9 do not need to move.

When the container 1 is placed on the uppermost holder 4 (or 5), the dried material 29 is irradiated with ultraviolet rays by an ultraviolet irradiation device 28 to sterilize it. If the moving speed, the drying time and the like are set on the control panel 39 so that the container 1 makes at least one rotation in the drying chamber 24, all the dried products 29
UV rays are always irradiated and sterilized.

[0012]

Since the present invention is configured as described above, it has the following effects.

Accordingly, the operation of moving the dried material during the drying is eliminated, and the labor is reduced. Also,
It is safe because there is no need to reach into the hot drying room. Furthermore, it can be dried without unevenness. , The movement is performed reliably and safely. As a result, hot air is reused, leading to energy saving. Thus, clean air is safely blown and clean drying is performed. , Sterilization is performed simultaneously during drying, and the efficiency is high.
