Abstract: A regenerating-type compressed air drier for regenerating compressed air by an electrical heating mechanism and a dehumidifying-and-regenerating unit are provided. The drier includes a dehumidifying-and-regenerating unit and an air distribution unit. Compressed high-humidity air and regenerating air are guided to the air distribution unit by a compressed high-humidity air piping and a regenerating air piping. The compressed high-humidity air and the regenerating air are guided to dehumidifying-and-regenerating components of the dehumidifying-and-regenerating unit by a shunt rotor of the air distribution unit to complete the dehumidification of the compressed air and the regeneration of the dehumidifying-and-regenerating components. The drier has a simple structure, and can reduce an undue loss of heat energy by an electrical heating mechanism to the regeneration of the dehumidifying-and-regenerating components.

Abstract: 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.

Abstract: 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.
