Abstract (en)
[origin: WO2011104453A1] The invention relates to a method implementing liquid CO2 as a cryogenic fluid for transferring negative calories to products, said method being of the so-called indirect injection type wherein the liquid CO2 is sent into a heat exchanger system where same evaporates, the method being characterized in that, prior to reaching the exchanger system, the liquid CO2 undergoes an expansion operation, at a pressure selected to obtain a gas/solid mixture at the output of the expansion operation.
