Beschreibung
Zusammenfassung:	The invention relates to the technical field of food processing, in particular to a processing method for improving the hot air drying quality of jujube slices, and aims to overcome the defects of low efficiency, poor texture quality, poor color and the like due to the fact that drying is carried out through natural airing or single hot air in the prior art. Comprising the following steps: (1) selecting fresh jujubes, cleaning, denucleating and slicing, (2) drying by adopting high-temperature and high-speed hot air at the early stage of drying, (3) reducing the temperature and the air speed of the hot air at the middle stage of drying and simultaneously applying continuous radio frequency heat treatment to assist hot air drying, and (4) carrying out intermittent radio frequency treatment at the later stage of drying to further reduce the temperature and the air speed of the hot air until the drying is finished. And (5) cooling and packaging the jujube slices. Compared with the prior art, the processing device
