    Abstract: The apparatus for making cooled concrete of this invention produces cooled fresh concrete by cooling the aggregate (or gravel). The aggregate is cooled by immersion in a cooling water bath accommodated in a cooling water tank. The cooling water in the tank is cooled by a heat exchanger, which in turn is cooled by a forced cooling device. The aggregate is immersed into the cooling water bath by a supply and ejection apparatus, which also removes the cooled aggregate from the cooling water bath. The cooled aggregate is supplied to a cement mixer where it is mixed to become cooled fresh concrete.

    Abstract: The method for cooling a liquid (2) in which a coolant comprising a refrigeration-liquefied gas is introduced into the liquid (2) and the corresponding device (1) make possible, in an advantageously simple manner, the production of cooled liquids (2), which, for example, can be used as process water in the production of freshly mixed concrete. In this case the enthalpy content of the coolant, preferably of liquid nitrogen, is utilized in a good manner, by firstly using the vaporization enthalpy, and secondly the heating of the nitrogen after vaporization up to ice temperature, for cooling the liquid.
