Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a method of soaking seed pods in hot water and adhering to the surface of the seed pods or lurking between the rice husks and the pericarp (rice blast disease, stupid seedling disease, seedling blight disease, sesame leaf blight disease, brown stripe disease, fir tree) The present invention relates to a hot water disinfection apparatus for seed potato that sterilizes, sterilizes, or disinfects (hereinafter referred to as “disinfection”).
[0002]
[Prior art]
Japanese Patent Application Laid-Open No. 2000-316321 or Japanese Patent Application Laid-Open No. 2000-342018 is known as an apparatus for disinfecting pathogens adhering to the surface of seed husks or hiding between rice husks and pericarp by immersing the seed husks in hot water at a predetermined temperature for a predetermined time. What is described in is known. Japanese Patent Application Laid-Open No. 11-318118 discloses a hot water disinfection device for a soot seed that hangs a soot container containing the soot seed with a self-propelled crane and puts it in and out of a hot water tank.
[0003]
[Problems to be solved by the invention]
In the seed sterilizer described in JP 2000-316321 A or JP 2000-342018 A mentioned above, not only simply immersing the seed pod in the hot water stretched on the hot water tank, By soaking, the hot water disinfection of the seed potato is ensured and the effect is improved. That is, in the hot water disinfection device for seed potatoes, a hot water spout unit is provided in the hot water tank, and when disinfecting the hot water of the seed pods, the seed jar containing the seed pods must be lowered onto the hot water squirting portion and placed on a fixed position. However, since the hot water tank is filled with hot water, the soot container is placed at a fixed position on the hot water squirting section from the top of the hot water tank in order to cause complicated photorefractive action and steam to rise due to the shaking. It is the actual situation that it is difficult to drop down. In particular, as shown in Japanese Patent Application Laid-Open No. 11-318118, in the case where a traveling crane is used for raising and lowering the soot container, it is more difficult to align the soot container with the hot water spraying part.
[0004]
Therefore, the present invention provides a guide unit that guides the soot container that is lowered from above to a fixed position on the hot water spraying part around the hot water spraying part, so that the seeding container is placed on the hot water spraying part in the hot water tank. Can be placed at a fixed position on the hot water spraying part simply by roughly aligning the seeding water container with the hot water spraying part, especially when a traveling crane is used to raise and lower the seeding water container. It is an object of the present invention to provide a hot water disinfection device for seed potatoes that can easily and accurately place the seed jar container on the spout unit.
[0005]
