Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tea production, in particular to a drum type tea dryer. BACKGROUND

[0002] Tea processing needs multiple processes, and drying is the last process in the primary processing of green tea, black tea, oolong tea and white tea. The purpose is to dehydrate the tea in a certain way, so as to achieve a certain moisture content for storage. During the drying process, complex thermal chemical reactions occur to ensure that the color, aroma and taste of tea are more perfect. Therefore, drying is one of the key processes for improving the quality of various teas. The traditional tea drying method is time-consuming and laborious, and the modern tea drying process uses a drum type tea dryer.

[0003] For example, the patent document with publication number CN220187291U discloses a drum type tea dryer, which includes a drying work bucket, a recovery mechanism and a heat circulation device. The recovery mechanism is installed with a servo motor, one side of the servo motor is movably sleeved with a transmission gear, the bottom of the transmission gear is transmissionally connected with a first gear, one side of the first gear is fixedly connected with a trapezoidal screw rod, both sides of the trapezoidal screw rod are fixedly connected with two bearings, and the middle of the trapezoidal screw rod is movably connected with a brush. The filter screen on the surface of the tea filter bucket is used to screen tea, and tea fragments or powder will fall into the bottom of the inner wall of the drying bucket through the holes of the filter screen. The cleaned tea fragments or powder will enter the collection box through the grooves opened in the drying bucket, and the collection box collects tea fragments or powder. These tea fragments or powder also have utilization value, solving the problem that fragments and powder will affect the next processing, and improving the quality of the dried tea. In the above device, tea dregs and finished tea are separated by the drum screen, but the separation efficiency of tea dregs is low due to the small weight of tea dregs relying on the self-weight of tea dregs to separate from the drum screen. Therefore, a drum type tea dryer capable of improving the separation efficiency of tea dregs is proposed. UTILITY MODEL CONTENT
