Drier null for photosensitive planographic printing edition

摘要

PURPOSE:To obtain a printing plate use drying device being advantageous heat-economically, by providing a circulating wind use air suction port on a side plate of a drying box, drying uniformly both the surface and the rear side of a printing plate, minimizing an outflow of a hot air to the outside of the drying box, and also, raising the drying efficiency without deteriorating the environment of an automatic developing machine chamber. CONSTITUTION:Air which is fed out of blower 7 is controlled as to its temperature by a heater 8, becomes a hot air of 60-80 deg.C, and led to upper and lower slit blow-off ports 9a, 9b. As for a method for suspending a duct 9 to a drying box, it is executed by coupling an end part 9c and 9d of the duct 9 into a hole which has been provided on side plates 3a, 3b. On the side plate 3b (the side plate of an outlet side of a drying air), many suction ports 13 are provided, and a suction of a drying circulating air is executed. The duct consist of a cylindrical shape of about a pentagon, one line thereof is opened and forms the slit blow-off ports 9a, 9b, and a drying air which has been led in from the end 9c of the duct 9 is blown out to the PS plate surface from the slit blow-off ports 9a, 9b, and dries a gum liquid.
