Definitions

  • the invention relates to a device for producing ice crystals in one aqueous solution.
  • DE 101 13 395 C1 is a scratch together with a scratch-guiding rotor (hereinafter described as "rotor") which can follow the contour by the scratch elastic and the changing geometry in radial and axial Geometry adapts.
  • rotor scratch-guiding rotor
  • the rotor shown in DE 101 13 395 C1 has at the upper and lower end depending a shaft which guides the rotor largely concentrically in the inner tube. At one The end is a bearing, at the other end the shaft with a seal to the outside guided and stored there again. Both bearings are usually as ball bearings (Roller or needle roller bearings are also conceivable) executed.
  • the wave is from a Motor driven, this engine also has bearings. To registration error as well as the "wobble" movement of the wave, caused by the not perfect Geometry of the inner tube to compensate, usually becomes a curved tooth coupling used.
  • the outside of the outer tube is also affected by evaporating refrigerant cooled, a use for fluid cooling and / or ice production, however, so far not done, since a scratch design for this at least difficult, if not is impossible. Expensive surface remains so unused and becomes small - around losses hold - thermally insulated. So far, in tubular ice makers no cold technical use of the outside takes place.
  • the invention is therefore based on the object, a device of the aforementioned To create a type whose cooling capacity is improved.
  • FIG. 1 a vertical ice maker is shown.
  • ice makers may also be inclined or horizontally arranged. From the non-vertical arrangement resulting adjustments of the pipe connections not further described below, as they obey the laws of physics and thus are known to a person skilled in the art.
  • the inner tube 1 and the outer tube 2 (hereinafter referred to as "double tube") form an annular gap 3, which is closed on both sides and in which a refrigerant can evaporate.
  • This refrigerant is in the annular gap 3 through a pipe socket 4 fed and leaves the annular gap 3 through a pipe socket. 5
  • both ends of the double tube lids are attached and a "lower" Cover 6 and an “upper” cover 7.
  • Both covers 6 and 7 are with the double tube tightly connected, e.g. by a flange connection (not shown in FIGS. 1 and 2).
  • a pipe section 8 through the lower cover 6 the fluid in the interior 9 introduced the double tube and passes through another pipe section 10th cooled and possibly enriched with ice crystals.
  • the evaporating refrigerant in the annular gap 3 of the double tube cools the inside of the inner tube 1. This can be with sufficient cooling of the fluid in the Interior 9 of the ice maker on the surface of the inside of the inner tube. 1 Ice crystals form.
  • the scratches 11 cover this area.
  • the scratches 11 are connected to a rotor 12 in a manner that they are elastic the non-circular and / or not straight Kontor of the inner tube can react.
  • the elastic connection is denoted by 13 and shown only schematically (it can e.g. to a resilient non-positive connection or a resilient form-fitting Compound - as indicated in DE 101 13 395 C1 - act).
  • the scratches 11 are exemplary in vertical 5 planes with two over the radius distributed scratches 11, with adjacent planes e.g. at each 90 ° offset. However, it can also have a different number of levels as well other arrangement and number of scratches 11 may be provided.
  • the rotor 12 has at the lower end no guided wave, i. there is no storage and no wave.
  • a stub shaft 14 is attached, which is connected to a gear tooth coupling 15.
  • This curved tooth coupling is connected to a shaft 16, which in turn in bearings 17 of an electric motor 18 is clamped.
  • the electric motor 18 is connected via a flange 19 with the upper lid 7 rigidly connected (It can also be a different number of bearings 17 and connections other than a flange 19 between the Electric motor 18 and the upper lid 7 are selected).
  • One (usually as Seal seal running) seal 20 seals the shaft 16 to the upper lid 7 off.
  • the scratches 11 in their arrangement in the above-described levels and a expedient division can lack of restraint by a bearing of the rotor 12 follow the contour of the inner tube 1 very well and paint the surface thus better. This is the icing of the inside of the refrigerant-cooled inner tube 1 significantly reduced. It can - without risk of ice formation on the inside of the inner tube 1 - a higher cooling capacity are driven than in constructions of ice makers, in which the rotor 12 clamped on both sides by bearings is. The attempt was less wear of the scratches 11 and the mechanical seal 20 as well as additional services up to 40% related to ice cream production determined.
