FPCG-30旋流式流化床包衣機

旋流式流化床包衣機，其包括依次連接相通的具有空氣進口的初效過濾器及中效過濾器、除濕器、冷熱風門、加熱器、高效過濾器、氣體螺旋導流筒、包衣容器、過濾室、引風系統、輸液及霧化系統和控制系統，在氣體螺旋導流筒的內壁上設有上升螺旋形的氣體螺旋導流板，所述包衣容器的外殼為球形的容器體，在包衣容器中設有氣流螺旋導流盤和旋轉霧化器，所述氣流螺旋導流盤經疊加呈圓錐形排列，旋轉霧化器伸出圓錐形的頂部。該發明能夠實現液化床內的氣流呈螺旋運動狀態，達到快速包衣且能干燥的功能，具有較高的包衣質量，所得表面包衣物均勻、光潔，能夠制備緩控釋制劑及掩味、著色。

摘要（英）：The invention discloses a spiral-flow type fluidized bed coater, which comprises an initial efficiency filter and a medium efficiency filter with air inlets, a dehumidifier, cold and hot air doors, a heater, a high efficiency filter, a gas spiral guide cylinder, a coating container, a filtering chamber, an induced draft system, an infusion and atomization system and a control system which are connected and communicated in turn. An ascending spiral gas spiral guide plate is arranged on an inner wall of the gas spiral guide cylinder; a shell of the coating container is a spherical container; airflow spiral guide discs and a rotary atomizer are arranged inside the coating container; and the airflow spiral guide discs are in conical arrangement through superposition, and the rotary atomizer extends out of the conical top. The spiral-flow type fluidized bed coater can realize the spiral motion state of the airflow in a fluidized bed, realizes the functions of rapidly coating and drying, and has high coating quality. The obtained surface coating is uniform and smooth; and the spiral-flow type fluidized bed coater can prepare slow-release preparations, and mask odor and color the preparations.
