A FIELD CONVENIENT JACKETED LEAF INACTIVATOR FOR GREEN TEA PROCESSING

摘要

A simple, convenient tea leaf roaster for efficiently inactivate the tea shoots to produce good quality green tea with minimum use of energy. The invention comprises of roasting tank (1) provided with a heating jacket (2) and an agitator (9) operated manually or by motor. The jacket containing thermic fluid is heated under controlled conditions to generate steam out of the tea shoots charged into the inactivation tank by taking the advantage of moisture present in the fresh two and a bud leaves. The contents in the treatment tank are gently heated up to help in efficient roasting of the leaf without imparting burnt aroma to the end product. The leaves are completely inactivated without exposing to higher temperature, and due to non-loss of juice from the shoots during the process; the quality of green tea is superior to leaves processed by earlier prior arts.
