Description

  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 device for seed potatoes that kills or inactivates bacterial blight diseases.

  Japanese Patent Application Laid-Open No. 2000-316321 discloses an apparatus for killing or inactivating (hereinafter referred to as “disinfection”) pathogenic bacteria attached to the surface of seed pods or hidden between rice husks and pericarp by immersing the seed pods in hot water at a predetermined temperature for a predetermined time. Or what is described in Unexamined-Japanese-Patent No. 2000-342018 is known.

  Also, a hot water disinfection device for seed potatoes that suspends a seed potato container containing seed potatoes with a self-propelled crane and puts it in and out of a hot water tank is described in Japanese Patent Application Laid-Open No. 11-318118 or Japanese Patent Application No. 2003-235308.

  Furthermore, a high temperature water tank for sterilization, a low temperature water tank for cooling, a treated seed supply part, and a treated seed take-out part are arranged on the circumference around the pillar, and five are supported radially by the pillar. Japanese Patent Application Laid-Open No. 8-9714 discloses a device for sterilizing vegetable seeds in which a bucket of seeds to be treated is suspended on each of the arms.

A hoist type overhead crane is disclosed in Japanese Patent Application Laid-Open No. 2000-109284 or Japanese Utility Model Laid-Open No. 6-53578.
