Problems solved by technology

However, the drum steamer also has disadvantages. First, the machine barrel is long and occupies a wide space; second, the tea raw materials cannot be stirred during the steaming process, and the tea leaves that are not fully mixed during the stacking process cannot be further stirred here. Uniformity, the product is prone to differences in taste; third, it is difficult for the tea to contact steam uniformly, resulting in uneven humidity and affecting the quality of fermentation

Abstract

The present invention discloses a dark green tea steaming system and relates to a dark green tea steaming device. The dark green tea steaming device includes a raw material conveyor and a disk type steaming machine hanging arranged at the discharge end of the raw material conveyor. A division plate is used to divide the middle part of an inner cavity of a disk type steaming machine barrel into a steaming bin and a stirring bin. A cylindrical cover seat is arranged in the middle part of the stirring bin and is combined with the machine barrel in a surrounding manner into a stirring groove. Steam distribution holes are evenly distributed on the division plate in the stirring groove. A feed outlet is arranged at the right side of the stirring groove. A steam conveyor pipe and a condensate pipe are arranged at a machine base. An M-shaped stirring rod is arranged on the cylindrical cover seat and two working stirring shovels are arranged at both ends of the M-shaped stirring rod in the stirring groove. The dark green tea steaming device is compact in structure, has a less floor space, and can fully and evenly stir the tea leaf raw materials, and thus the tea leaves are even and uniform in tea leaf contacting steam and the tea leaves have uniform moisture. The dark green tea steaming device can significantly improve the fermentation quality, and the product has no significant difference in taste and is high in production efficiency.

Description

technical field [0001] The invention relates to a dark tea steaming device. Background technique [0002] In the production process of dark tea products, the dark tea raw materials need to be re-fermented. First, the tea raw materials must be steamed to soften, and then fermented. The original method is steaming with a steamer. Now there is a barrel-type fermentation machine, that is, a barrel-type steamer. The tea raw materials enter from one end of the barrel-type steamer, and after steaming soft, they are extruded from the other end, which can significantly save labor and improve production. efficiency. However, the barrel steamer also has disadvantages. First, the machine barrel is long and occupies a wide space; second, the tea raw materials cannot be stirred during the steaming process, and the tea leaves that are not fully mixed during the stacking process cannot be further stirred here. If it is uniform, the product is prone to differences in taste; third, it is di...
