    Abstract: The invention relates to a method for cooling materials, in particular food, in a cooling apparatus, the cooling being completely or partially carried out by contacting the materials with a cryogenic liquid. Said method is characterized in that the contacting is carried out by means of the injection of two cryogenic liquids, nitrogen and CO2. The liquid nitrogen and the liquid CO2 are injected either separately, into at least two injection points of the apparatus, or by mixing both cryogenic fluids at the injection point. The invention is of use if the apparatus being utilized is a mixing, batch mixing, or grinding chamber, with the injection being carried out into the body of the material in the bottom portion of the chamber.

    Abstract: The subject of the invention is a method for shaping at least one food product by cryoextrusion, the extruder being provided with a double-walled jacket surrounding the extrusion screw and through which jacket a coolant flows, this jacket consisting of a single module or several independent modules, the cryoextrusion being temperature-regulated on the basis of a curve, determined for said product to be cryoextruded, representing, plotted on the X-axis, the difference D between the actual temperature of the product and the desired temperature setting for the product at the exit and, plotted on the Y-axis, the setting to be applied for the gas temperature at the exit of the module or modules, the curve being split into three linear zones: an abrupt (steep-slope) zone, around a difference D close to 0, surrounded by two quasi-plateau zones.
