Tea-steaming machine suitable for making famous and high-grade tea

Abstract

The invention discloses a tea leaf steaming machine suitable for preparing famous tea, which comprises a frame and a rotating drum. The rotating drum comprises a rotating drum cylinder section and a rotating drum conical section. Interval uniformly distributed annular electrical heating tubes are respectively arranged on the external surface of the cylinder section and conical section. The plane of the center line of each electrical heating tube is perpendicular to the axial line of the rotating drum. Each electrical heating tube is electrically connected to the temperature control unit on the top of the rotating drum. The interval between the electrical heating tubes on the external surface of the cylinder section is smaller than that between the electrical heating tubes on the external surface of the conical section. Compared with present technology, with the configuration, the invention has the advantages of no thermal inertia, uniform and fully steaming, and improved product quality.

Description

technical field [0001] The invention relates to tea machinery, in particular to a tea greening machine suitable for making famous and high-quality tea. Background technique [0002] The tea degreening machine has been widely used in the production of tea leaves. The utility model patent of Chinese Patent No. 200420080585.4 discloses a tea roller degreening machine, which includes a frame and a rotating hollow degreening cylinder placed on the frame. The degreening cylinder is a hollow interlayer structure. , there are heat-conducting oil and electric heaters or externally heated heat-conducting oil circulating through it, and the inner wall of the drum has a spiral guide vane plate. With such a structure, there is thermal inertia in the tea leaves during the greening process, which causes scorched edges, burnt leaves, and red stems to appear in the tea leaves, which affects the quality of greening. Contents of the invention [0003] The technical problem to be solved by t...
