Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, and specifically to a tea drum de-enzyming machine with a preheating device. Background Art

[0002] During the production of tea, a drum de-enzyming machine is used to de-enzyming fresh tea leaves, destroy the activity of enzymes in the fresh leaves, dissipate moisture, make the tea leaves wilt, and achieve the purpose of tea de-enzyming; the existing drum de-enzyming machine consists of a shell and a drum; the drum is horizontally arranged, with the two ends being the input end and the output end respectively, and runs through both sides of the shell, and is rotationally connected to the shell; a cavity is arranged inside the shell, and a heating structure and a driving structure are arranged in the cavity to drive the drum to rotate and heat; a spiral guide vane is arranged inside the drum, and after the tea leaves are put into the input end of the drum, they will move axially along the guide of the guide vane to the output end, and the tea leaves will be de-enzymed by high temperature during this moving process.

[0003] When the existing drum de-enzyming machine is de-enzyming, the temperature of the inner wall of the drum can be as high as more than 200 degrees Celsius; although there are differences in the local temperatures of the drum, the drum will still have relatively high temperatures everywhere due to heat conduction; when the fresh tea leaves at room temperature of about 20 degrees Celsius suddenly come into contact with the high temperature at the input end of the drum, due to the too large temperature difference, it is extremely easy to cause the surface of the fresh tea leaves to be coked, that is, carbonized. The coked surface of the fresh tea leaves hinders the removal of moisture inside the fresh tea leaves and the transfer of heat to the inside of the fresh tea leaves, resulting in poor de-enzyming effect.

[0040] When the tea leaf drum fixation machine with a preheating device in this embodiment is specifically used, first, the temperature of the heating furnace 431 is freely adjusted so that the preheating drum 3220 can freely adjust to a low temperature. The fresh tea leaves are poured into one end of the preheating drum 3220 far away from the fixation drum 111. When the fixation drum 111 rotates, it will drive the preheating drum 3220 to rotate. The rotation of the preheating drum 3220 will make the tea leaves move axially into the fixation drum 111 through the spiral guide plate 3221. During the movement, the tea leaves are preheated at a relatively low temperature so that they have a relatively close temperature when entering the fixation drum 111, and there is a gradual temperature increase process to avoid coking on the surface of the fresh tea leaves. After the tea leaves are preheated, they enter the fixation drum 111 of the fixation machine main body 110 for fixation.
