Abstract
PURPOSE: To obtain green tea of middle grade having increased aroma, by subjecting green tea leaves in the production of raw green tea from a roughly rubbing stage prior to an intermediate rubbing stage to high-temperature treatment.
CONSTITUTION: Green tea leaves, sent from a roughly rubbing or twirling stage, having a reduced water content about 50wt% and remaining 70W80wt% of aromatic essential oil, are divided into small portions, fed through a feed chute 2 to a rotary cylinder 1 heated at high temperature by a burner 4 and subjected to high- temperature treatment. The water content of resinous liquid containing the essential oil coming up to near the surface of green tea leaves is evaporated instantly and the resinous liquid containing the essential oil is allowed to permeate into the inner part of the mesophyll of the tea leaves.
