The internal volume of the liquid separator is made large enough to accommodate the amount of liquid nitrogen necessary to cool one batch of concrete mixed in the device, and the entire dead weight of this gas-liquid separator can be measured on a load cell. A liquid nitrogen supply device for producing cooled concrete, in which the weight of liquid nitrogen supplied to the device is detected by a load cell.
