The invention relates to a bean powder material package, a method and a device for manufacturing soyabean milk. A backwash area is formed on the bottom wall of the bean powder material package. The method for manufacturing the soyabean milk comprises the following steps: (a) pre-dissolving stage: an injection head is provided for injecting liquid to the material package through a membrane, and the liquid penetrates a bean powder layer to the backwash area with a flat surface or a concave surface on the bottom wall of the material package to form a liquid flow channel and (b) dissolving stage: the liquid is continuously injected to the material package by the injection head and is splashed reversedly through the backwash area to dissolve the bean powder upwards from the bottom of the material package layer by layer until the bean powder is completely dissolved, a leading-out hole is provided, and the soyabean milk in the material package is extruded to be discharged through the leading-out hole. With the adoption of the bean powder material package, the method and the device for manufacturing the soyabean milk, the liquid is injected to penetrate the bean powder layer to the backwash area on the bottom wall of the material package to form the liquid flow channel by the injection head, and the liquid is blocked and backwashed through the backwash area to form a fountain effect, so that the liquid is fully diffused to increase the dissolving area, and the agglomeration phenomenon of the bean powder is not easy to occur in a bean powder dissolving process, so that the prepared soyabean milk is uniform in concentration and better in mouth feel.本發明關於一種豆粉料包、豆漿製作方法及製備豆漿的設備。該豆粉料包的底壁形成反濺區,該豆漿製作方法包括:(a)預溶階段:提供注射頭,該注射頭穿過膜片注射液體至料包內,液體穿透豆粉層至料包底壁的平面或凹面反濺區形成液流通道;(b)溶解階段:該注射頭持續向料包內注射液體,液體經反濺區反濺從料包的底部向上逐層溶解豆粉直到完全溶解豆粉,提供引出孔,料包內的豆漿經引出孔擠壓排出;液體經反濺區受阻反濺從而形成噴泉效應,使液體充分擴散增大溶解面積,豆粉在溶解的過程中不易出現團聚現象,如此製備的豆漿濃度均勻口感較好。12‧‧‧料包121‧‧‧膜片122‧‧‧容器1221‧‧‧底壁1222‧‧‧側壁123‧‧‧反濺區
