<P>PROBLEM TO BE SOLVED: To provide a method for rapidly producing dried tea leaves by which raw tea leaves are rapidly heated and dried to provide the dried tea leaves without passing a step for heating and drying the raw tea leaves and arranging the shapes like the conventional production of Sencha (a kind of green tea), and by which the dried tea leaves having excellent chromaticity and flavor are produced without causing the reduction of the chromaticity and the flavor even by the rapid drying, and to provide an apparatus therefor. <P>SOLUTION: The method for rapidly drying and heating the raw tea leaves includes forming at least one of a belt and a heating drum provided in the apparatus into an air-permeable state, and heating the raw tea leaves inserted between the belt and the drum by a heating means, or inserting the raw tea leaves onto an air-permeable net conveyor adjacent to a metal plate heated by a heating means installed in the drying chamber and heating the raw tea leaves, to carry out the parching treatment and/or the heating and drying treatment. A step for carrying out a cutting treatment of the tea leaves after the parching treatment of the raw tea leaves is set so as to follow the parching treatment step of the raw tea leaves in the method for heating and drying the raw tea leaves. As a result, the reduction of the chromaticity and the flavor such as the insufficiency of drying, the reduction of the chromaticity, and the insufficiency of the flavor of the tea leaves, caused by the rapid drying is improved, and the dried tea leaves having the excellent chromaticity and flavor like the Sencha are produced. <P>COPYRIGHT: (C)2013,JPO&INPIT |
