。 Temperature control means that controls the flow rate of a mixed gas of steam and air supplied to the culture tank based on the operation output obtained by controlling and calculating the deviation between the temperature measurement value of the culture tank and the sterilization temperature setting value, and a temperature control means that controls the flow rate of a mixed gas of steam and air supplied to the culture tank, and a fixed amount of steam from the top of the culture tank. a first bleed valve means for periodically supplying steam on and off; a second bleed valve means capable of controlling valve opening for periodically supplying steam supplied from the bottom of the culture tank; function generating means for reducing the opening degree of the second bleed valve as the measured steam temperature increases until the temperature in the culture tank reaches the sterilization temperature; A culture tank sterilization control device comprising: sequence means for reducing the on/off cycles of the first and second bleed valves over time after a lapse of time.
