Reference numeral 8 denotes a frame that supports the drying unit 1, and 9 is a discharge chute 10 that drops and feeds the seeds dried by the drying unit 1 to the second storage tank 7.

  In the drying unit 1, a drying chamber 15 through which drying air passes, a soy seed storage unit 16 that is formed in a hopper shape that temporarily stores seed soy supplied from the first storage tank 7, and soot in the seed soy storage unit 16 is used as the drying chamber 15. There are provided a rotary valve 17 for supplying a constant amount of soot and a discharge control valve 18 for supplying a predetermined amount of seed soup in the drying chamber 15 to the discharge chute 10. The discharge control valve 18 is configured to rotate about a horizontal axis, and is configured to freely rotate.

  An operation panel 25 is a blower switch 26 for driving / stopping the blower 3, a rotary valve switch 27 for driving / stopping the rotary valve 17, a switching valve switch 28 for switching a switching valve 21 described later, and a discharge control valve. An angle adjustment dial 29 for adjusting 18 rotation angles is provided.

Next, the drying action of the seed meal will be described.
The first storage tank 6 for storing the seed soaked in water is placed on the top of the drying section. Then, when the opening / closing shutter 11 is opened, the seeds in the first storage tank 6 are supplied into the seeds storage unit 16. When the rotary valve 17 starts driving, the seeds are sequentially supplied into the drying chamber 15 by a predetermined amount. Then, while receiving the action of the drying air passing through the ventilation hole 2 formed from the starting end of the flow in the drying chamber 15 to the terminal end of the flow, the drying chamber 15 flows down, and a discharge control valve 18 provided at the terminal end of the flow is provided. The discharge chute 10 is discharged while the discharge amount is adjusted by setting the opening angle. Then, the soot discharged to the discharge chute 10 falls and is supplied to the second storage tank 7. The seeds overflowing above the discharge control valve 18 fall into the discharge chute 10 as it is. That is, the drying wind is made to act while the seed potatoes flow down in the drying chamber 15 sequentially and are discharged to the discharge chute 10.

  When the operator visually recognizes that seeds have disappeared from the seed storage downstream passage 6a of the first storage tank 6 and determines that all seeds have been stored in the second storage tank 7, the opening / closing shutter 11 of the first storage tank 6 is closed, Each part of the apparatus is stopped by various switches of the operation panel 25, and the first storage tank 6 and the second storage tank 7 are removed from the mounting position.

Then, when the set time elapses, the discharge control valve 18 is adjusted to open, and the soot in the drying chamber 15 is discharged to the discharge chute 10 by the air blowing action. Then, when the set time elapses, the discharge control valve 18 is closed again and the rotary valve 17 is driven until the soot seed detection sensor 19 detects the soot presence.

  With this configuration, the seed meal in the drying chamber 15 can be reliably dried. The attachment position of the seed soot presence detection sensor 19 can be set to an appropriate seed soot amount in the drying chamber 15 by setting the position so as to be substantially the same height as the rotational axis position of the discharge control valve 18.

Next, the removal operation of residual seed soot will be described.
A switching valve 21 for switching between opening and closing in the exhaust tube 5 is provided in the exhaust tube 5. That is, after all the seeds in the first storage tank 6 are dried in the drying unit 1 and stored in the second storage tank 7, the switching valve 21 is switched to the side that closes the exhaust pipe 5, and the discharge control valve 18 is set. The fan 3 is driven by adjusting to the open side. Then, the residual grains in the drying chamber 15 are discharged to the discharge chute 10 by the blowing action of the blower 3. At this time, since the switching valve 21 is closed, it is possible to prevent the residual seed soot from being scattered from the exhaust pipe 5 to the outside of the machine and to reliably discharge the residual seed soot in the drying chamber 15 to the discharge chute 10. be able to. Therefore, it is possible to prevent the following types, such as varieties and producers, from being mixed with different seed varieties. In addition, it is good also as a structure which provides the switch (not shown) for exclusive use at the time of the removal operation | work of residual seed soot in the operation panel 25, and when the said switch is operated, the wind force of the air blower 3 will be enlarged. Further, when a dedicated switch (not shown) for removing residual seed soot is operated, the switching valve 21 is switched to the side for closing the inside of the exhaust tube 5 and the discharge regulating valve is automatically fully opened. good.

  2 is different from FIG. 1 in that a large number of ventilation holes 20 are formed in the seed soot reservoir 16, and at the time of removing residual seed soot, a switching valve 21 is provided on the side that closes the inside of the exhaust pipe 5 as described above. Switching, adjusting the discharge control valve 18 to the open side, and driving the rotary valve and the blower 3. Then, the drying air passes through the ventilation hole 20, the residual seed soot in the seed soot storage unit 16 is fed to the drying chamber 17 by the rotary valve 17, and the residual seed soot in the drying chamber 17 is discharged to the discharge chute 10.

  Therefore, all the remaining seed pods in the seed potato storage unit 16 and the drying chamber 17 can be discharged to the second storage tank 7 and the next varieties and producers can be prevented from being mixed with different seed potatoes.

  It should be noted that this residual seed soup removal operation is performed when the above-mentioned operator visually recognizes that seed soot has disappeared in the seed soot flow down passage 6a of the first storage tank 6 and determines that all seed soot has been stored in the second storage tank 7. good.

  Next, based on FIG. 3, the process of shipping the rice cake that has been carefully selected in the previous process to the seed rice is described. 30 is a dredging flow rate adjustment tank that temporarily stores after a pre-selection process, and 31 is a sales meter that measures the amount to be seeded in advance. Reference numeral 32 denotes a seed potato flow rate adjusting tank for temporarily storing seed potato to be seed potato, 33 a seed potato disinfection device, and 34 a seed potato drying device for drying the sterilized seed potato. Reference numeral 36 denotes a soot shipping tank that stores seed soy dried by the soot drying apparatus, and 37 is a soot shipping tank that stores normal edible soy sauce. 38 is a shipping meter for weighing, and 39 is a seed selection selector valve for selecting and switching the soot weighed by the sales meter 31 to either the seed disinfecting device 33 or the shipping tank 37. This is a drying selection switching valve for switching whether the seed cake dried by the drying device 34 is dried again by the seed cake drying device 34 or conveyed to the seed cake shipping tank 36. In addition, the arrow shown in FIG. 3 has shown the conveyance process of the soot.

The process of shipping the set amount of seeds will be described below.
When the soot that has been carefully selected and temporarily stored in the soot flow adjustment tank 30 is shipped as seed soup, it is supplied to the sales meter 31, and the soot for a predetermined shipment amount is measured and supplied to the soot seed flow adjustment tank 32. The And it disinfects with warm water etc. with the seed soy disinfection apparatus 33, and is dried with the seed soot drying apparatus 34, and removes the water | moisture content on the surface of a seed soot. Then, it is stored in the seed vat shipping tank 36. Then, it is weighed again by the shipping scale 38 and shipped.

  The soot other than the amount of the soy sauce shipped is not supplied to the soy disinfection device 33 and the soy seed drying device 34 as normal edible soy, but is supplied to the soy shipping tank 37 by switching the soy seed selection switching valve 39. Then, it is weighed by the shipping weighing instrument 38 and shipped.

  Since the seed sterilized with the seed sterilizer 33 cannot be sold except for the seed potato, the seed sterilized exceeding the necessary shipment amount must be discarded. According to the present embodiment, it is possible to reduce waste seeds by previously measuring seed seeds to be disinfected by the seed seed disinfection device 33. Further, since the weighing is again performed by the shipping weighing instrument 38, an accurate shipping seed amount can be measured.

  Further, the soot in the soot flow rate adjusting tank 30 which does not need to be used as seed can be supplied to the soot shipping tank 37 by the seed soot selection switching valve 39 and can be shipped for food.

  The seed pod drying apparatus according to the present invention temporarily applies dry air to the cocoon in order to prevent the high-moisture freshly collected cocoon stored in the storage tank from decaying when receiving the cargo and in the order of receiving the cargo. It can be used in a cargo receiving and drying apparatus for exposure.
