< Topic >Culture earth such as the sawdust which is incorporated to the stem root section of the mushroom where hanabiratake and the like is cultivated artificially is removed, the removal device and its manner of the culture earth which comes in contact with the stem root section of the effective use possibility, for food mushroom the stem root section as raw materials and the like of the health food are offered. SolutionsBeing the conveying path of the tip/chip of the stem root section which is conveyed by the laser light irradiation device 13 which irradiates the laser light in order to incinerate only the culture earth which was laid out in the upper part of the conveying path of the tip/chip of the stem root section which is conveyed by the conveyer 12 which conveys tip/chip 20of a the stem root section which is sliced by the slice device 11 which slices the stem root section 20 of for food mushroom and the slice device to specified direction and the conveyer comes in contact with the tip/chip and the conveyer the laser light irradiation device compared to it was laid out in the upper part of the conveying path of downstream side, in laser optical lighting meansFrom washing away the burned ash of the culture earth which is incinerated, shower device 14 of the high water pressure in order to remove and, it possesses. < Choice figure >Drawing 1【課題】ハナビラタケ等の人工栽培されたキノコの茎根部に取り込まれているおがくず等の培養土を除去し、茎根部を健康食品の原料等として有効活用可能な、食用キノコの茎根部に付着した培養土の除去装置及びその方法を提供する。【解決手段】食用キノコの茎根部20をスライスするスライス装置11と、スライス装置によりスライスされた茎根部のチップ20aを所定方向に搬送する搬送装置12と、搬送装置により搬送される茎根部のチップの搬送路の上方に配置された、チップに付着する培養土のみを焼却するためのレーザ光を照射するレーザ光照射装置13と、搬送装置により搬送される茎根部のチップの搬送路であってレーザ光照射装置よりも下流側の搬送路の上方に配置された、レーザ光照射手段により焼却された培養土の焼却灰を洗い流して除去するための高水圧のシャワー装置14と、を有する。【選択図】図1
