- the method has the advantage of producing fine particles of very small size, preferably with a narrow size distribution.
- the device has the advantage that a solidifying liquid can be supplied at a temperature above its solidification temperature without cooling gas, which is used in the generation of the particles, leading to solidification of the liquid in the supply line.
- the liquid is allowed to solidify by means of a cooling gas, which is introduced into a nozzle as a propellant gas and preferably by subsequently introducing the mixture of the liquid and propellant gas, or of fat and propellant gas, which emerges from a nozzle, into a space with cooled gas, whereby fine particles are formed.
- the propellant gas has a temperature below the solidification temperature of the liquid or fat.
- No. 4,952,224 A describes, for the production of fat particles, the spraying of hot liquid fat through a heated Venturi nozzle and the subsequent flow of nitrogen or carbon dioxide as cooling gas onto the spray jet in its direction of movement.
- the object of the invention is to provide an alternative device and an alternative method for producing fine particles from a liquid which solidifies when cooled.
- the device and the method should be particularly suitable for the production of fine particles with a narrow size distribution and without larger droplets.
- the invention solves the problem with the features of the claims and in particular by means of a method and a device which has a nozzle, to whose inlet opening, which is arranged at the first end, a propellant gas supply line is connected and to whose inlet opening a supply line for the liquid which in particular is liquid fat, opens.

- the convex surface preferably extends rotationally symmetrically around the longitudinal axis of the central channel and particularly preferably has a convex surface which extends radially around the longitudinal axis of the central channel, wherein the surface can be parabolic, for example, the slope of which increases in the direction of the longitudinal axis of the central channel, that is, the slope of which increases with a decreasing radius, in order to form a curvature increasing towards the longitudinal axis.
- the nozzle can only extend over a first section between the inlet opening and its smallest radius, so that it is in its smallest radius ends, or that the central channel ends in its smallest radius, and spans the outlet opening. In this embodiment the nozzle is an unexpanded nozzle.

- the propellant gas feed line preferably forms an annular feed line with an annular opening at the inlet opening of the central channel.
- the ring-shaped opening of the supply line is limited by the surface of the central channel that spans its inlet opening.

- Inlet opening can be sucked.
- the nozzle can have an air inlet opening open to the environment between the feed line for the liquid and the central channel.
- gas e.g. propellant gas returned after flowing out of the outlet opening can be fed to the air inlet opening.

- gas that is fed to the air inlet opening can be raised to a temperature between room temperature and the temperature that the liquid has in its inlet line or above it
- the device generally comprises a cooling device which cools the gas supplied to the air inlet opening, e.g. to the temperature of the propellant gas supplied to the nozzle, e.g. -90 to -60 ° C.

- the nozzle and / or the feed line can e.g. to 150 to 250 ° C, e.g. 180 to 220 ° C, e.g. 200 ° C heated.
- a heatable nozzle has the advantage of liquefying or vaporizing fat deposited on the central channel during the process, so that it is then cooled to particles by the propellant gas.
- the nozzle and / or the feed line for the liquid can be heatable in that it contains electrical heating elements or channels for a heat transfer medium to pass through on or in its wall.

- the countercurrent unit generates a countercurrent of cooled gas from a
- Countercurrent or at least two partial countercurrents e.g. is directed at an angle of 90 ° to 180 ° against the gas flow emerging from the nozzle.

- particles, in particular from fat are preferably produced by cooling from a liquid, in particular from liquid fat, which has a temperature above its solidification temperature, the liquid being generated by a feed line up to the region of the nozzle in the negative pressure , while propellant gas is passed through the
