PROBLEM TO BE SOLVED: To narrow the mounting area of a seed disinfector for heating seeds with hot water to disinfect the seeds.SOLUTION: In a state that a raw material M is received in a conveying basket 68, in a hot water disinfector 10, the conveying basket 68 is conveyed in a hot water tank 18 to disinfect the raw material M with hold water 20, and then is conveyed in a cold water tank 28 to cool the raw material M with cold water 30. Herein, the hot water tank 18 is a vertical type tank, and the vertical direction maximum dimensions of the inner and outer portions of the hot water tank 18 are larger than the horizontal direction maximum dimensions, respectively. In addition, the cold water tank 28 is a vertical type and the vertical direction maximum dimensions of the inner and outer portions of the cold water tank 28 are also larger than the horizontal direction maximum dimensions, respectively. Therefore, the mounting area can be narrowed.COPYRIGHT: (C)2012,JPO&INPIT【課題】据付面積を狭くする。【解決手段】温湯消毒装置10では、搬送篭68内に原料Mが収容された状態で、搬送篭68が温湯槽18内に搬送されて原料Mが温湯20によって消毒されると共に、搬送篭68が冷水槽28内に搬送されて原料Mが冷水30によって冷却される。ここで、温湯槽18が縦型のものにされて、温湯槽18の内部及び外部がそれぞれ上下方向最大寸法を水平方向最大寸法に比し大きくされている。しかも、冷水槽28が縦型のものにされて、冷水槽28の内部及び外部がそれぞれ上下方向最大寸法を水平方向最大寸法に比し大きくされている。このため、据付面積を狭くできる。【選択図】図1
