To be controlled. Reference numeral 14 denotes a low-temperature storage, which stores the seeds dried after disinfection at a low temperature.

  Next, the processing flow of the soy sauce disinfection system will be described with reference to FIG. 2. When the soy sauce is brought into the facility, it is first put into the carry-in hopper 15. The seed hopper 15 is placed in the seed hopper tank 17 by the upper conveying device 16 from the carry-in hopper 15, and the worker puts the seed potato in the seed hopper tank 17 into the small net bag A made of synthetic fiber (nylon) by the weighing device 18 in 5kg. Close the mouth of the small net bag A on the table 18 with a sewing machine or tied with a string. Then, 8 small net bags A each containing 5 kg of seed pods are put into a large synthetic fiber (nylon) large net bag B, and the mouth of the large net bag B is closed with 40 kg of seed varieties in the state. A plurality of bags B are placed in the immersion basket 20 of the hot water disinfection device 19.

  The immersion basket 20 containing a plurality of large net bags B containing 40 kg of seed potatoes is automatically lifted by the crane 21 and sequentially immersed in the hot water sterilization tank 22 and the cold water tank 23, and then in the basket storage area 24. The movement is controlled so as to be placed. In addition, the seed cake is subjected to specific gravity selection with a salt water having a specific gravity of 1.13 or more to remove the seed cake having a low specific gravity, and then washed with water to remove the salt. Then, drain the water and dry the seed pods to a moisture content of 15%. On the other hand, the hot water sterilization tank 22 contains hot water maintained at 60 degrees Celsius by the control device, and the immersion basket 20 containing a plurality of large net bags B containing seed potatoes is placed in the hot water sterilization tank 22. It is soaked for 10 minutes, and immediately after that, it is soaked in a cold water tank 23 containing tap water (cold water) to cool the seeds.

  The operator removes the large net bag B from the immersed basket 20 placed in the car storage area 24 after the hot water disinfection, dehydrates it with the centrifugal dehydrator 25, and attaches the large net bag B to the hook of the drying carriage 26. Suspend sequentially.

  Then, a drying carriage 26 in which a plurality of large net bags B are suspended is placed in a drying chamber (budding chamber) 10, and the seed cake is dried with a heater 11 until the water content becomes 15%, and then dried and cooled with cold air. . Thereafter, the drying cart 26 is taken out from the drying chamber (budding chamber) 10 and the sterilization bag B containing the seed sterilized and dried is moved to the seed container 27 and stored in the low temperature storage 14 at a low temperature. Is done. In addition, when it is decided to ship the seed vat, the small net bag A is taken out from the large net bag B and transferred to a paper bag and sealed, or transferred to a mesh container and shipped. When the small net bag A is transferred into a paper bag and sealed, the worker will not touch the seed vat afterwards, so that the disinfected state is maintained properly (the germs attached to the operator's hand etc. High quality seeds can be shipped and used.

And when picking up from a facility, a paper bag or a mesh container is taken out from the low temperature storage 14 and shipped.
Also, when seeding and raising seedlings using seed pods at the same facility, take out a paper bag or mesh container from the low temperature storage 14, sow the seed pods, germinate, dehydrate them, send them to the seeding machine 3, and The seedlings are sown and the seedlings are shipped. When seeding and raising seedling work is performed immediately after disinfection and drying, the seed pods taken out from the drying room (emergence room) 10 are sent to the seeder 3 side as they are.

  In the above embodiment, an example is shown in which all three drying chambers (budding chambers) 10 are used as chambers for drying and cooling the seed pods. For example, the lowermost drying chamber (budding chamber) 10 in FIG. Is used as a chamber dedicated to drying seed pods, and when drying is completed, it is transported from the lowermost drying chamber (budding chamber) 10 and transferred to the middle drying chamber (budding chamber) 10. If the dedicated room for cooling the seed pod is used, the lowermost drying room (budding room) 10 can continue to dry with the heating drying, and the middle drying room (budding room) 10 cools the seed pod with cold air. Can be continuously performed, the thermal efficiency is improved, the drying operation can be performed at a low cost, and the working efficiency is greatly improved.

  FIG. 3 shows another example of the drying carriage 26, which also serves as the carriage section 28 of the budding carriage P, removes the upper frame that supports the seedling box stacking body in which seedling boxes are stacked, and instead uses a net bag. An upper drying frame 30 having a large number of hooks 29 for hanging B is mounted. Thus, by using the carriage part 28 of the budding carriage P also as the drying carriage 26, the material can be effectively used, and the equipment cost of the seedling facility is reduced.
