Problems solved by technology

The energy used to heat the outer wall of the drum includes firewood, coal, electricity, gas, electromagnetic, etc. Heating the outer wall of the drum to fix the tea leaves is likely to cause burnt edge bursts in tea production or insufficient water stuffiness, which affects the quality of tea, and the thermal efficiency is low and energy consumption is high.

Abstract

The invention discloses an electrical combined heating type tea leaf fixation machine. The electrical combined heating type tea leaf fixation machine comprises a cylinder body, wherein the cylinder body comprises a barrel-type housing, and a barrel-type liner; the barrel-type liner is arranged in the barrel-type housing in a sleeving manner, and the inner wall of the barrel-type housing and the outer wall of the barrel-type liner form an air chamber; a roller is arranged in the barrel-type liner, and the axle centre lines of the barrel-type housing, the barrel-type liner and the roller coincide; a rotating shaft is arranged along the axle centre line of the roller, and two axial ends of the roller are fixed to the rotating shaft; air inlets are formed in the wall of the barrel-type housing, and communicate with the air chamber, an air inlet end of each air inlet is connected with an electric heating air source, and air vents are uniformly distributed in the wall of the barrel-type liner; an air outlet is formed in the wall of the barrel-type liner and penetrates through the barrel-type housing to communicate with the outside; and the roller consists of mesh grids. Tea leaves do not need to be in direct contact with a heating cylinder body, so that the problems that due to too high local contact temperature, edges of tea leaves are coked and blisters occur are solved, and uniform heating in an entire process is realized, so that the sterilizing efficiency is improved.

Description

technical field [0001] The invention relates to tea processing equipment, in particular to an electric combined heating type tea greening machine. Background technique [0002] Tea greening is to destroy and passivate the oxidase activity in fresh tea leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, make tea soft, easy to knead and shape, and emit green odor at the same time Taste, a tea-making step that promotes the formation of a good aroma. The basic structure of the roller tea greening machine is to include a frame, the frame is provided with a casing, the casing is provided with a roller, and a heating mechanism for heating the roller is provided between the casing and the roller. In the drum, the outer wall of the drum is heated by the heating structure during the rolling process of the drum to achieve greening. The energy used to heat the outer wall of the drum includes firew...
