The harvested fresh leaves will have a water loss rate of 30%, and the greening machine will start to preheat. The seals will be inspected at various parts. The fresh leaves will be spread at the feeding port and sent out through the conveyor belt for two minutes to reach the level of killing.

Production Green Tea => Japan . Nowadays, the process of green tea distribution in Japan is almost entirely automated. The process is somewhat more complicated than that of the Chinese. It comprises the following steps: 1) Withering . The withering reduces approximately 30% of the humidity content of the leaf within a time of 4-12 hours. 2 ...

Black Tea Manufacture. Black tea, which is the most commonly consumed tea in the world is the one processed in the largest amount among all types of tea.
