Process 1: Withering
Withering is the first process in orthodox tea manufacture. Freshly plucked tender green tea leaves are spread on the huge trough tables with large mesh bottoms. Below the mesh was a fan system, which blew hot and cold air alternatively into these leaves causing to lose 50% of their moisture. Once the leaves turned brown, an innovative duct system helped the workers to directly transfer the leaves to the rolling machine on the ground floor for the next Process.
