After that, water accounting for 8 to 10 times of the weight of the glede tea powders is added into an extraction tank, heated to 75 to 90 DEG C at the room temperature, added with the tea powders for stirring extraction for 8 to 12 minutes. Then the materials are filtered by a filter screen being 200 to 300 meshes to obtain filter liquid (1). Water accounting for 4 to 6 times of the weight of the filter residue is adopted for extracting for 4 to 6 minutes under the same conditions of the filter residue. The filtering operation is carried out by the filter screen being 200 to 300 meshes to obtain filter liquid (2). The filter liquids (1) and (2) are merged and added into the extraction tank. The filter liquid is heated to 60 to 80 DEG C and the pressure thereof is reduced the to -15kPa to 20kPa for concentration. Condensed liquid, i.e. aromatic water, is collected. The collecting of the condensed liquid is stopped until the weight of the condensed liquid is 1 to 1.5 times of that of the tea powder. Then concentration is continuously carryed out until the weight is 1 / 4 to 1 / 3 of the total filter liquid weight. The spray drying is carryed out to obtain dry powder. The prepared dry powder, the aromatic water, the white granulated sugar and the citric acid are mixed and prepared. The glede tea beverage has the advantages that the tea beverage has the effects of relieving summer heat and quenching the thirst, helping digestion and enhancing the human body immunity, the quality is easy to control, and in addition, the taste is good.
