Tea powder is a product manufactured from drying tea solution which was received after fermentation on Fermenter. In this research, we used spray drying method on spray dryer ZLPG-5/1.1 in order to produce of tea powder product from tea bran. The main aim is to obtain the best product recovery yield, the good moisture of the product and the product has high biological activities, we carried out the experiments to find the optimal conditions for the production of tea powder such as the effect of the ratio of maltodextrin/fermentation tea solution and the effect of drying air temperature. The result as follows the ratio of maltodextrin/fermentation tea solution was 15%, the drying air
temperature was 100oC. In these conditions, moisture of the product was 4,61%, the product recovery yield was 80– 82%. Besides, the acid glucuronic content of the product was 2,51mg/g, the product didn’t contain pathogenic microorganism and safe for consumers.
