The invention belongs to the field of tea processing, and in particular discloses a process for processing and producing tea. The process comprises three steps of feeding, performing air intake and drying and needs a tea drying device. The tea drying device comprises a storage bin, a settling mechanism and a tea drying mechanism; a conveying belt is arranged below the storage bin; the settling mechanism comprises a Y-shaped pipe and a powder collecting tank; the tea drying mechanism comprises a spiral drying channel and a drying fan; the upper end of the spiral drying channel is connected with the storage bin and the lower end of the spiral drying channel is connected with the drying fan; the spiral drying channel comprises an inner drying channel and an outer drying channel; a plurality of sieve holes are formed in the side wall of the inner drying channel uniformly; the inner drying channel is connected with the storage bin; the upper end of the outer drying channel communicates with one branch pipe of a Y-shaped pipe; the lower end of the outer drying channel communicates with the drying fan; and the confluence section of the Y-shaped pipe is positioned above the powder collecting tank. According to the scheme, the drying efficiency of the tea can be greatly improved while the tea quality is guaranteed.
