Abstract: A device and method for drying a fluorescent material are provided. The device includes a container having a predetermined space for containing a fluorescent material, a first driver for rotating the container, a heater for heating the container, a vacuum unit for creating a partial vacuum in the container to discharge moist air from the container, a supplier for supplying dry air to the container, an exhausting unit for exhausting the fluorescent material dried in the container, and a controller for controlling the respective device and the first dryer. The drying method includes the steps of placing a cleaned fluorescent material into a dryer, heating the dryer while rotating the dryer, injecting dry air into the dryer and exhausting moist air from the dryer, and vacuum-transferring the fluorescent material from the dryer to a predetermined storage tank. With the device and method, drying a wet fluorescent material without hardening it obviates the need for a grinding process and reduces a drying time and manual processes. Thus, a fluorescent material drying process can be performed by few personnel in a clean working place.

Abstract translation: 提供了用于干燥荧光材料的装置和方法。 该装置包括具有用于容纳荧光材料的预定空间的容器，用于旋转容器的第一驱动器，用于加热容器的加热器，用于在容器中产生部分真空以从容器排出湿空气的真空单元， 用于向容器供应干燥空气的供应器，用于排出在容器中干燥的荧光材料的排气单元，以及用于控制各个装置和第一干燥器的控制器。 干燥方法包括以下步骤：将清洁的荧光材料放入干燥器中，在干燥器旋转的同时加热干燥器，将干燥空气注入干燥器中并从干燥器排出湿空气，并将荧光材料从干燥器真空转移至 预定储罐。 使用该装置和方法，在不进行硬化的情况下干燥湿荧光材料，从而避免了研磨过程的需要并减少干燥时间和手工操作。 因此，荧光材料干燥过程可以由干净的工作场所的人员进行。
