[0004] The above-mentioned patent dries the atomized liquid medicine in the box by an electric heating fan. Since the water mist mixed with the liquid medicine adheres to the inner wall of the box, crystalline medicine particles are slowly formed during the gradual drying process. These particles are sticky to the inner wall of the box. Only when the crystalline particles become larger and larger, and their own weight is greater than the friction force attached to the surface of the box, they will be separated from the inner wall of the box under the action of gravity and fall off. Since the volume of these crystalline particles gradually increases during the drying and forming process, it does not meet the requirements of the subsequent powder for tablets and powder for capsules. Therefore, the crystalline medicine particles need to be ground again to make them into smaller medicine powder. Therefore, the present application provides a chemical pharmacy spray drying device.
