PROBLEM TO BE SOLVED: To provide a tool which can be acquired at an ordinary household and can be easily operated, because when extracting coffee in a state in which chaff is adhered to roasted coffee beans, off-flavor occurs and flavor may be deteriorated, and therefore it is necessary to remove the chaff from beans.SOLUTION: Coffee beans which have been roasted are put into a net 3 in a container 1, then the coffee beans are stirred by a wooden spatula or the like, and then only chaff can be sucked out from a pipe 2 connected to an activated cleaner. Since sucking of the chaff and stirring of the coffee beans are performed simultaneously, all beans can be cooled in a uniform state. When a lid 4 having small holes is attached, an air volume entering from holes of the lid is smaller than an air volume sucked by the cleaner, so that inside of the container becomes a negative pressure state, and the lid and container come into close contact with each other. In the state, when the container is lifted up by both hands and shaken vertically, the beans temporarily exists in the air, and adhesion degree between beans is reduced, so that suction of the chaff and cooling can be performed simultaneously.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】焙煎した珈琲豆にこのチャフが付着したまま珈琲を抽出すると、雑味として現れ味が損なわれるため豆からチャフを取り除く必要がある。そのため、一般家庭でも容易に入手でき、なおかつ簡単に操作できる道具を提供する。【解決手段】容器1内の網3に焙煎の終わった珈琲豆を入れて、木ベラなどで珈琲豆を攪拌して、起動させた掃除機につないだパイプ2からチャフだけを吸い出すことが出来る。同時に攪拌することにより全ての豆をムラなく冷却することが出来る。小さい穴があいたフタ4をすると掃除機が吸い込む空気量よりフタの穴から入る空気流入量が少ないので容器内が負圧になりフタと容器が密着する。この状態で容器を両手で持ち上げ上下に振ると、豆が一時的に空中にある状態になり、豆同士の密着度が減るのでチャフの吸引と冷却が同時に行うことが出来る。【選択図】図1
