the cavity opening 115 in order to discharge the expanded gas from the sphere an exhaust channel is arranged at the joint of the upper and the lower cavities 102 107 a protecting net 118 that is fixed on supporting rods 100 is provided inside the spherical cavity to operate this apparatus withdraw the loading cover assembly axially from the barrel cavity 1 as seen in fig1 in doing so the compressed air tube 30 must be lifted slightly upwards arrange the object 16 to be sterilized around the center of the air jet orifice plate 23 then reset the loading cover assembly the pressurized water and compressed air are supplied to the water injecting tubes 15 the compressed air cavity 22 is under the control of the control circuit illustrated in fig3 as a result of the positioning pin 19 having reached its proper position the object to be sterilized is washed by the injection of compressed air and pressurized water next under the control of the control circuit heated compressed air is supplied and the injection of pressurization water is stopped and the object to be sterilized is dried the object to be sterilized is taken from the barrel cavity 1 and is mounted on the movable intermediate joint 111 of the integrated ball for sterilization the object to be sterilized is then put into the spherical cavity of the sphere the pulse xenon lamp flashes a total of 6 times at intervals of one second between each flash at this stage under the action of the control circuit the.
