the present invention may be seen a roasting process proceeding from the inside through a drum having a heat resistant glass tube and more particularly to relates to a portable coffee roaster, the front cover and the spacing plate is installed apart while flowing through the external air into the interior of the drum will have to discharge the smoke and the champ in the drum to the outside the roasting is done reliably. It installed a plurality of stationary stirring blades fastened axis in the interior of the heat-resistant glass and and fixed only at both sides of a circular panin front cover, one front cover has signed an investment outlet of the fallopian tube shape, and the other the front cover, air inlet between forming the ball and the drum formed plate is spaced at the front, fastened to the other side of the front cover of the drum is rotated by a driving motor inside it is formed a rotation axis of the bearing fastening and projected to the outside on the outer surface of the rotary shaft engaging shoulder a main body consisting of a handle coupling groove is formed The fastening drum of the main unit is to be rotated, and an upwardly protruded on the upper surface projections and the one supporting plate that is formed by the central pin fixed to the front of the coupling grooves and projections, the one supporting plate and symmetrical, yet the engagement groove center in the fixing groove is formed in the lower side of the and the pedestal and the other support plate is formed integrally with, and sealing the front and back of the support plate and the protective plate consisting of a support bar bolted to the upper holder Fastened to the support plate of the cradle, and will have an air inlet filter is mounted inside the lower side is formed geolreummang is formed inside the upper side, the forming a fixed pin protrudes outside the outer peripheral surface, and projected to the outside on the upper side of the push pin 2 entered into between the jaw c
