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.
