A method for pasteurising and restoring the refrigerant cycle in a freezing machine for making crushed-ice drinks and the like and a machine for implementing the method
A method for pasteurising and restoring the refrigerant cycle in a freezing machine (1) for making crushed-ice drinks and the like comprises a pasteurising step during which a predetermined maximum temperature (T1) is reached and a step of restoring the refrigerant cycle, during which a predetermined freezing temperature (T3) is reached the step of restoring the refrigerant cycle comprises a sub-step of rapid cooling of the pasteurising temperature with a first thermal excursion (ΔT) with passage from the temperature (T1) to a temperature (T2) and a sub-step of slow cooling from the temperature (T2) to the freezing temperature (T3) with a second thermal excursion (ΔT"), in which the first thermal excursion (ΔT) is greater than the second thermal excursion (ΔT").
