Shaping, enzyme deactivating and drying treatment process of selenium-enriched green tea

Abstract

The invention discloses a shaping, enzyme deactivating and drying treatment process of selenium-enriched green tea. The process comprises the following steps: a quantitative conveying mechanism and afeeding mechanism pull tea leaves to fall into an extrusion shaping mechanism in a state that the leaf root ends face downwards and the leaf tip ends face upwards; an extrusion driving component drives an extrusion shaping mechanism to be in an extrusion state, an extrusion convex plate extrudes and shapes the tea leaves, and meanwhile a heating element heats the tea leaves for fixation; after shaping and fixation of tea leaves, the extrusion driving component drives the extrusion shaping mechanism to be in a revoked state; in this process, firstly, a drag hook arranged on a pull plate drags atrigger closed switch to be in a cancelling state, shaped tea leaves fall downwards, then a cancelling bulge arranged at the top of a cancelling plate enables the drag hook to cancel the traction onthe trigger closed switch, the trigger closed switch is switched back to the closed state, and meanwhile, the next batch of tea leaves fall into an extrusion shaping mechanism; and the shaped tea leaves fall into the heating and drying device downwards for heating and drying treatment.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to the field of shaping and drying of tea. Background technique [0002] Tea processing is the manufacture of tea. The traditional Chinese tea making method is divided into two processes: primary processing and refining. The primary processing of tea is the process of making dry tea from fresh tea leaves through a series of manufacturing processes. The manufacturing processes are different. The tea leaves are different, which is the key to the formation of different teas. That is to say, different teas are formed from the same fresh leaf raw materials using different tea-making processes. In the process of tea processing, it is generally necessary to Tea is flattened. For example, the production of Taiping Houkui is very particular about flattening. Although the existing tea flattening devices are widely used, the overall flattening effect is not very good, and the pressure during flat...

[0002] Tea processing is the manufacture of tea. The traditional Chinese tea making method is divided into two processes: primary processing and refining. The primary processing of tea is the process of making dry tea from fresh tea leaves through a series of manufacturing processes. The manufacturing processes are different. The tea leaves are different, which is the key to the formation of different teas. That is to say, different teas are formed from the same fresh leaf raw materials using different tea-making processes. In the process of tea processing, it is generally necessary to Tea is flattened. For example, the production of Taiping Houkui is very particular about flattening. Although the existing tea flattening devices are widely used, the overall flattening effect is not very good, and the pressure during flattening cannot be controlled. , it may cause the tea leaves to be crushed during the flattening and shaping process, which seriously affects the subsequent tea processing procedures and the quality of the processed tea leaves. Therefore, it is necessary for the present invention to propose a tea shaping equipment that can squeeze the tea leaves The entire tea processing process is fully automated by pressing and shaping, heating and finishing, and drying. The staff only need to pour the tea into the conveying shell and receive the processed tea at the bottom of the discharge cylinder, which greatly reduces the labor of the staff. strength and increased work efficiency
