Vacuum cooling device

This invention provides a vacuum cooling device capable of cooling a foodstuff to a target temperature. The vacuum cooling device 1 contains: a first cooling control unit 501 which reduces the internal pressure of a cooling tank 2 to a first target pressure value by pressure reducing means 3 and maintains the internal pressure of the cooling tank 2 at the fist target pressure value for a first time period after the internal pressure has reached the first target pressure value; a foodstuff temperature judging unit 502 which determines, after the cooling by the first cooling control unit 501, whether the detection temperature of a foodstuff temperature sensor 21 has reached the target temperature; and a second cooling control unit 503 which contains a second cooling hold control unit 5033 which newly sets the temperature when the temperature determined by the foodstuff temperature judgement unit 502 has not reached the target temperature, by reducing the first temperature from the set temperature, reducing the
