Hot air tea fixation machine

Abstract

The invention discloses a hot air tea fixation machine. A roller comprises a front roller body and a rear roller body, the length of the front roller body occupies one fifth of the length of the whole roller, a high-temperature-resisting heat insulation pad adheres to the inner wall of the front roller body, and the rear roller body is connected with a rotating motor. A plurality of guide blades are annularly arranged on the inner wall of the rear roller body, a blocking sheet is arranged on the guide blades, and due to the fact that the high-temperature-resisting heat insulation pad adheres to the inner wall of the front roller body, the edges of tea leaves are prevented from being burnt. Due to the fact that no guide blade is arranged in the front roller body, it can be avoided that due to the fact that the tea leaves and the guide blades are in contact, the edges of the tea leaves are burnt. The length of the front roller body occupies one fifth of the length of the roller, part of water in the tea leaves is evaporated through heat transfer of high-temperature gas in the front roller body, when the high-temperature gas reaches the rear roller body, the temperature of the gas starts to be reduced, the guide blades push the tea leaves to move towards an outlet, and it is avoided that due to the fact that the temperature of the tea leaves is reduced fast, the taste of the tea leaves is influenced.

Description

technical field [0001] The invention relates to a tea green fixing machine, in particular to a hot air tea green fixing machine. Background technique [0002] The processing of tea leaves includes processes such as drying, greening, rolling, and drying. During processing, the freshly picked tea leaves are first aired for 2-3 hours, and then put into a tea greening machine for greening. Greening is done by destroying and passivating the green leaves in fresh tea leaves at high temperature. Oxidase activity, inhibits the enzymatic oxidation of tea polyphenols in fresh leaves, evaporates part of the water in fresh leaves, softens the tea leaves, and facilitates subsequent rolling and shaping. . [0003] The tea greening machine that appears in the prior art includes a bracket, a drum, a guide vane, an air pipe, a thermometer and a hot blast stove. The drum is fixedly connected to the bracket, and the guide vane is arranged on the inner wall of the drum. There is a tea outlet,...
