| titleOfInvention | Device and process for the cryogenic filling of aerosol product batches |
| abstract | In order to avoid evaporation of the propellant gas during the pressure-free filling of an aerosol formulation provided with a readily volatile propellant gas, the product to be filled is cooled prior to being fed into a metering means. In this context, fluoro-chlorinated hydrocarbons such as, for instance, R11 have been used up until now as the coolant, but their use is no longer permitted in Germany and in other nations. n Consequently, it is proposed according to the invention that an evaporator be installation upstream from the heat exchanger employed to cool the aerosol product batch, in which evaporator a liquid coolant is evaporated and then brought to the temperature required to cool the aerosol product batch by a regulating means. n The invention makes it possible to employ environmentally safe coolants such as, for instance, nitrogen, without running the risk that the aerosol formulation will freeze during the cooling procedure. In this context, the invention allows the coolant temperature to be selected at will over a wide range. |
