The invention provides a high-quality grape drying device and method.The high-quality grape drying device comprises a flotation system, an infrared hot air drying system, a steam generator and a control system, and under the control of the control system, through the flotation system, a high-quality grape is obtained; the infrared hot air drying system and the steam generator complete the steps of grape classification, high-temperature blanching enzyme deactivation, infrared hot air drying and infrared sterilization at a time. The method is particularly suitable for seedless bletilla striata and other grape varieties with high sugar content, fresh grapes with different densities are distinguished by adopting salt solutions with different concentrations, rapid lossless classification based on internal quality is realized, and the classification speed is high; the method has the advantages of simplicity in operation and high efficiency; compared with a traditional method of corroding the peels of berry material
