Zusammenfassung:To provide a beverage extraction device capable of providing beverages appropriately.SOLUTION: A beverage extraction device for extracting a beverage in an extraction chamber includes: a tubular cylinder; a filter feeding part for feeding a belt-like filter so that an unused region of the belt-like filter for filtrating the beverage is positioned below the cylinder; a filter block configured to be moved relatively with respect to the cylinder, which forms the extraction chamber by closing an opening at a lower end of the cylinder with the belt-like filter between the filter block and the lower end; a discharge part provided in the filter block for discharging the beverage extracted in the extraction chamber; and an abnormality detection part for detecting whether or not a residue of a raw material used for extracting the beverage is transported accompanying a feeding operation of the belt-like filter by the filter feeding part.SELECTED DRAWING: Figure 13 【課題】飲料を適切に提供することができる飲料抽出装置を提供すること。【解決手段】飲料抽出装置は、抽出室で飲料を抽出する飲料抽出装置であって、筒状のシリンダと、前記飲料を濾過する帯状フィルタの未使用領域が前記シリンダの下方に位置するように、前記帯状フィルタを送るフィルタ送り部と、前記シリンダに対して相対移動可能に構成され、前記帯状フィルタを間に挟んで前記シリンダの下端の開口を塞ぐことにより前記抽出室を形成するフィルタブロックと、前記フィルタブロックに設けられ、前記抽出室で抽出された飲料を吐出する吐出部と、前記フィルタ送り部による前記帯状フィルタの送り動作に伴い、前記飲料の抽出に用いられた原料の残渣が搬送されなかったか否かを検出する異常検出部と、を備える。【選択図】図13
