A process for producing a flavor-rich tea from tea leaves is disclosed. It comprises the steps of: (a) plucking the tea leaves; (b) withering the tea leaves; (c) rolling the tea leaves; and (d) drying the tea leaves in a drying apparatus in a circulating air at a drying temperature in the range of from about 30.degree. C. to less than about 80.degree. C. while maintaining a relative humidity of the circulating air in the range about 1% to 30%, the drying apparatus comprising a dehumidifying device for dehumidifying air, a temperature-moisture controlling device, and a drying room. The tea made from this process is capable of being subsequently stored at room temperature and substantially retains flavor-producing volatile constituents. Optionally, the tea leaves after step (d) can be baked for a short time to produce a roasted flavor.

Process and an apparatus for producing teas

A new kind of teas named 'dry fresh tea' is prepared by drying tea leaves in circulating air at low temperature and low humidity. Quality of teas is improved by preserving volatile flavors.
