The present invention relates to a cylindrical ribbon mixing dryer, in particular to form a drive motor and inlet in the upper portion and the outlet in the lower portion to minimize the gap between the inner surface of the housing and the rotary blade to increase the mixing efficiency of the mixing as possible The outer circumferential surface is provided with a housing in which a heating jacket is installed, and in the center of the housing a spiral shaft rotating blade which is supported by a plurality of supports to be interlocked with the driving motor, wherein the fruit flow path is formed on the rotating shaft and the rotary blade. In the ribbon mixing dryer is configured to form the housing having a cylindrical shape having the same diameter from the top to the bottom and the outlet is formed in the center of the bottom surface of the housing so as to be in the same line with the rotary shaft and the outlet to the bottom of the rotary shaft The auxiliary blade corresponding to the spiral rotation But formed in a cylindrical shape so as to correspond with the wings around the inner peripheral surface of the cylindrical housing, is a cylindrical skirt of the ribbon type mixing dryer being configured so as to be in contact with the bottom surface of the housing.
