the dye cycle itself began accordingly the level of bath liquid in the tub might be higher than what might be required and to this end the excess liquid over a minimum bath volume is drained from the tub by opening the valve 64 however the bath liquid remaining is constantly being circulated throughout the tub by the pump 44 and the tub is continually being rotated by motor 17 in order to keep the bath uniform throughout the tub during the initial stages of cool down the temperature of the bath is near or at the boil so that a significant amount of vapor release occurs from the agitated bath surface from the small bath droplets being splashed about inside the tub and even from the wetted goods and tub structure upon opening the dampers 68 and 82 and upon operating the blower 76 cooler air probably at a temperature between 70 u00b0 and 120 u00b0 f is drawn through the inlet tube 66 and tub enclosure and over the agitated bath for passage through the blower 76 and discharge from line 77 preferably to the outside atmosphere via line 79 this draws the bath vapors away from the tub enclosure and discharges them likewise outside of the tub enclosure the bath itself is moved axially.
