Before we dive into the machines used in tea production, it’s essential to understand the process itself. Tea production involves several stages, including:
Plucking
Tea leaves are plucked from the tea plants, usually by hand or using mechanical pluckers. The quality of the tea leaves is crucial, and plucking is done at the right time to ensure the best flavor and aroma.
Withering
The plucked tea leaves are spread out in a controlled environment to allow excess moisture to evaporate. This process, called withering, helps to soften the leaves and prepare them for the next stage.
Rolling
The withered tea leaves are then rolled to release the enzymes that cause oxidation. The rolling process can be done by hand or using machines, depending on the type of tea being produced.
Oxidation
The rolled tea leaves are left to oxidize for a period of time, which can range from a few hours to several days. The level of oxidation depends on the type of tea being produced, with black tea being fully oxidized and green tea being minimally oxidized.
Firing
The oxidized tea leaves are then heated to stop the oxidation process and dry out the leaves. This stage is crucial in determining the final flavor and aroma of the tea.
