  • Patent number: 5423288
    Abstract: An apparatus for producing seed crystals in melts has a vertically oriented, closed vessel having a vessel base and having at least one inlet for the melt and having at least one outlet opening for the inoculated melt provided with seed crystals. A preferably annular region of the vessel wall is constructed as a cooling surface. In the interior of the vessel there is arranged a scraping unit which comprises a motor-driven rotating shaft which extends axially through the vessel as far as a point just short of the vessel base. At its end towards the vessel base, the shaft is provided with at least one scraping arm which, starting from the lower end of the shaft close to the vessel base, extends first in the direction towards the vessel wall and thence substantially parallel to the annular cooling surface and axially parallel to the drive shaft.
