To provide a recovering method for sucrose and a sucrose recovering device that recovers sucrose from syrup at low cost while producing a little waste liquid.SOLUTION: A sucrose recovering method includes: a diluting process of diluting an extract from crops containing sucrose with water to produce a sugar diluted solution; a layering process of layering a solvent which is highly hydrophilic and contains a very small or small amount of water on the sugar diluted solution; and an intermediate layer forming process of forming an intermediate layer including sucrose having been transferred and the solvent between a formed layer of the sugar diluted solution and a layer of the solvent, the solvent being removed from the intermediate layer recovered in an intermediate layer recovering process to recover the sucrose. A sucrose recovering device is configured to implement the sucrose recovering method, and comprises an intermediate layer formation tank, an intermediate layer extraction mechanism, a solvent supply mechanism, and a circulation mechanism.SELECTED DRAWING: Figure 1 【課題】廃液が少なく、かつ低コストに、糖蜜から蔗糖を回収する蔗糖回収方法および蔗糖回収装置を提供する。【解決手段】蔗糖回収方法は、蔗糖を含有する作物由来の抽出物を水で希釈して糖希釈液を生成する希釈工程と、親水性が高く、微量または少量の水を含有する溶媒を、前記糖希釈液に積層する積層工程と、積層した前記糖希釈液の層と前記溶媒の層との間に、移行した蔗糖および前記溶媒を含む中間層を生成する中間層生成工程と、を含み、前記中間層回収工程で回収した中間層から前記溶媒を除去して前記蔗糖を回収する。蔗糖回収装置は、上記蔗糖回収方法を実施する装置であって、中間層生成槽、中間層抜き出し機構、溶媒供給機構、および循環機構を備える。【選択図】図１
