Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a configuration of a drying system according to the present invention, FIG.
FIG. 3 is a cross-sectional view of the main dryer.

The main dryer 1 is an ordinary circulation type dryer,
A separate box-shaped drying section 2 is formed, and the main dryer 1
The exhaust port 5 and the box-shaped drying section 2 are connected by an exhaust path 3,
The exhaust wind heat discharged from the main dryer 1 is caused to flow into the box-shaped drying unit 2. That is, the hot air generated by the combustion of the burner 10, which is the drying heat source of the main dryer 1, and the air sucked from the exhaust path and the like are pressure-fed by the fan 4 attached to the exhaust port 5 and sent to the box-shaped drying unit 2. The arrows in FIG. 2 and FIG. 3 schematically show the flow of the air and the like.

The exhaust air that has flowed into the box-shaped drying unit 2 is sent upward through the mesh 8. At this time, black soybeans 9 with branches and leaves housed on the opening net 8
Is dried by the exhaust heat.

Further, the temperature of the exhaust air heat is measured by an exhaust air temperature sensor 7 installed near the inside of the exhaust port 5, and the temperature of the exhaust air temperature sensor 7 is set so that the temperature of the exhaust air heat becomes a preset temperature. The combustion amount of the burner 10 is controlled based on the detected value, and hot air temperature control for drying black soybeans is performed. In the same manner as the conventional method of controlling the combustion amount of the burner 10 so that the detection value of the hot air temperature sensor 6 installed in the hot air chamber for controlling the hot air temperature becomes the set temperature, the conventional method for calculating the grain temperature is used. By controlling the hot air temperature for black soybeans using the detection value of the exhaust air temperature sensor provided as
All operations can be performed by the operation panel, and the drying unit 2 does not need a control unit.

As described above, the drying system of the present invention takes in exhaust air from a conventional circulating rice and wheat dryer into a separately provided drying section, and uses the exhaust air as a heat source to dry black soybeans and the like. In addition, since the operation section and the control section are performed on the main dryer side, it is possible to provide an inexpensive drying system for drying crops such as black soybean which cannot be dried while being circulated.

The exhaust passage 3 can be provided with an air flow regulating valve for adjusting the amount of exhaust air and a vent hole for exhausting the exhaust air out of the exhaust passage 3. FIG. 4 is a longitudinal sectional view (a) and a side sectional view (b) showing the structure of such an air flow control valve 11 and the air vent hole 12. By providing such an air volume control valve 11 and the air vent hole 12 at a connection portion between the entrance of the drying unit 2 and the exhaust passage 3, the air volume to the drying unit 2 can be adjusted. In other words, by changing the rotation direction of the air volume control valve 11, the air volume passing therethrough is adjusted, and by adjusting the opening and closing of the air vent hole 12, the air volume to be discharged is adjusted.

Since the main dryer 1 is usually adjusted to the amount of air and the amount of heat in accordance with the processing capacity of rice and wheat, if the exhaust air is used as it is, it may not be suitable for drying black soybeans and the like. Therefore, in order to dry black soybeans and the like, it is necessary to adjust the capacity of the main dryer 1. However, if the discharge air volume of the main dryer 1 is reduced, overheating of the burner, troubles in the combustion state, and the like occur, and therefore the present invention. Then, the air volume control valve 1
By providing the air vent 1 and the air vent hole 12, the air volume is adjusted to be suitable for drying black soybeans and the like.

The box-shaped drying unit 2 which is a flat type drying machine is generally open at the top, but in the present invention, as shown in FIG. It can be constituted by the member 13. Black soybeans, etc. are put into the drying section 2 with branches and dried by applying hot air. Therefore, if the upper part of the drying section 2 is open, it is ventilated only in places where there is no ventilation resistance, and the hot air circulates evenly throughout. The trouble that only a part is dried easily occurs without performing. Therefore, in the present invention, as described above, the upper opening of the drying unit 2 is made of, for example, a breathable cloth (light shielding net, linen cloth, towel cloth).
By covering and fixing with, etc., the internal pressure in the drying section 2 is increased, and ventilation resistance is provided, so that hot air can be circulated evenly throughout the entirety, so that hot air can reach every corner of the black soybean branch. be able to.

Next, in connection with the present invention, a panel type assembly,
The configuration of the box-shaped drying unit that can be disassembled will be described. FIG.
FIG. 4 is a perspective view showing the configuration of such a box-shaped drying unit which can be assembled and disassembled in a panel. As shown in the figure, the box-shaped drying unit has four panels 14 to 17 (front and rear, left and right) which are the lowermost base part (panel 17 is not shown),
Opening nets (bottom nets) 18 and 19 installed in the base portion constituted by the four panels, an additional frame installed on the base portion and constituted by four panels 20 to 23,
It is composed of pressure adjusting plates 24 and 25 made of a permeable member installed so as to cover the upper opening end of the additional frame.
Joining of the panels is performed by a fixture (not shown). As described above, by assembling and disassembling the box-shaped drying section by using the panel assembling method, it is easy to assemble and disassemble, and it can be disassembled and stored except during the season, and the storage space after disassembly can be saved.

Next, in connection with the present invention, a description will be given of the configuration of the box-shaped drying unit which can freely set the opening direction for taking in and out of the crop. FIG. 7 is a perspective view showing the configuration of such a box-shaped drying unit. As shown in the figure, the box-shaped drying section includes a lowermost base section 26, meshing nets (bottom nets) 27 and 28 installed in the base section 26, and an installation section on the base section 26. Storage sections 29A and 29B. The base 26 and the storages 29A, 29B are both square frames. And storage unit 2
Both 9A and 29B allow the front plate 29a to be removed. In the assembled state, the front plate 29a is fixed by the lever 30 attached to the side plate 29b.

The taking in and out of the crop from the drying section is performed in the storage section 2.
9A and 29B (in this example, the front plate 29a) are removed, and the base unit 26 and the storage unit 29 are used as described above.
Since both A and 29B are square frames, the open surface can be freely formed by assembling the storage portions 29A and 29B on the base portion 26 by changing the position where the front plate 29a comes (change by 90 degrees). it can. Therefore, it is possible to bring an open surface on either side due to the layout of the workplace.
