摘要： The present invention relates to a method and a device for completely condensing a process gas (P) by cryocondensation, comprising the following steps: cooling a gaseous cooling medium circulating in a cooling loop (10) by a liquid cooling medium in a main heat exchanger (11), whereby vaporizing the liquid cooling medium, feeding the vaporized cooling medium into the cooling loop (10) upstream of the main heat exchanger (11), cooling heat exchange surfaces (5) in a condenser (3) by the gaseous cooling medium circulating in the cooling loop (10), feeding the process gas (P) to be condensed into the condenser (3) to bring it into contact with the heat exchange surfaces (5) in the condenser (3), collecting the condensed process gas (P) as liquid product (LP) in a product container (8), and extracting gaseous cooling medium by an extractor (16) from the cooling loop (10) and guiding it through a pre-cooler (2) for pre-cooling the process gas (P) before feeding it into the condenser (3). The invention allows to completely condensate a process gas (P) by using the cold of a liquid cooling medium in three steps. In a main heat exchanger (11) the phase transfer from liquid to gas is used. In a second step the still very cold gas is introduced into the cooling loop (10), and in a final step the temperature difference between the cooling loop (10) after the heat exchange surfaces (5) in the condenser (3) compared to the environment (25) is mostly used in a pre-cooler (2). This highly efficient use of the cold allows using the process and the device according to the invention on an industrial scale for completely condensing a process gas (P).

摘要： Nozzle installation (1) for spraying a substance that is supposed to be pulverized, comprising:
- a first inlet (2) for the substance,
- a second inlet (3) for a driving medium,
- an outlet (4), through which the substance can be driven by the driving medium,
- a heating line (5) that is arranged such that the substance can be heated between the first inlet (2) and the outlet (4) by the heating line (5),
- a first temperature sensor (6) arranged at the outlet (4), and
- a control unit (9) configured for controlling the heating power of the heating line (5) based on a first temperature measured by the first temperature sensor (6).
By means of the described methods, the described nozzle installation (1) and the described device (11), pulverization of a substance such as a fat can be performed in a particularly reliable manner. Due to a controlled heating of the substance prior to spraying the substance into a spray tower (12), a particular uniform particle size distribution can be achieved and clogging of a nozzle installation (1) can be prevented.
