Referring to fig. 1-3, a dryer for enzymatic or fermentation materials is shown, which comprises a cylindrical drying cylinder 1, wherein the lower part of the drying cylinder 1 is a conical part 11, and the conical part 11 is provided with a discharge hole 13; a feeding port 2 is formed in the upper part of the drying cylinder 1, and the feeding port 2 is tangent to the inner wall of the drying cylinder 1; a rotating shaft 4 with a hollow channel 42 is arranged at the axis position in the drying cylinder 1, the lower end of the rotating shaft 4 is arranged above the discharge hole 13, and the upper end of the rotating shaft penetrates through the top of the drying cylinder 1 and is connected with an exhaust pipe 8; a driving motor 32 is arranged outside the drying cylinder 1, and the driving motor 32 is in driving connection with the rotating shaft 4; a plurality of fins 5 are arranged on the outer edge of the rotating shaft 4 along the circumferential direction, and a plurality of through holes 51 are formed in the fins 5; the inner wall of the drying cylinder 1 is provided with a spiral flow passage 12.

Specifically, taking a fermented material as an example, the fermented material is mixed with air flow and cut into the drying cylinder 1 from the feeding port 2, and the fermented material performs centrifugal motion in the drying cylinder 1; meanwhile, the rotating shaft 4 rotates, the fins 5 on the rotating shaft 4 continuously flap the fermentation materials, so that the fermentation materials condensed into blocks are broken away, and the through holes 51 on the fins 5 can reduce the air resistance on the fins 5 and facilitate breaking away the fermentation materials condensed into blocks; during the centrifugal movement of the fermentation material, part of the moisture in the fermentation material becomes water-vapor separation, and when the fermentation material rotates and moves downwards to the conical part 11 of the drying cylinder 1, the rotating and descending airflow continuously flows into the central part of the drying cylinder 1 during the descending process to form centripetal radial airflow, and the airflow forms an internal rotational flow which rotates upwards, and the internal rotational flow is mixed with the water vapor and flows out through the hollow channel 42 of the rotating shaft 4 and is finally discharged from the exhaust pipe 8. While the fermented material is discharged from said outlet 13.

Therefore, on the basis of the principle of the cyclone separator, the spiral flow channel 12 is arranged on the inner wall of the drying cylinder 1 and adds the rotating force and the rotating speed of the airflow to ensure that the stress of the feed is stronger; in addition, the fin 5 is added in the drying cylinder 1 for stirring, which is beneficial to scattering the condensed feed, so that the drying effect of the enzymolysis or fermentation material is better.
