Definitions

  • the invention relates to a method and a device for removing water ice from a cooling system for cooling goods to a temperature below the freezing point of water.
  • freezing is also used in the sense of deep-freezing and means that the refrigerated goods are exposed to direct or indirect contact with a refrigeration medium at a sufficiently low temperature for a sufficiently long period of time that, following the freezing process, they reach a core temperature below the freezing point of water.
  • a core temperature of -18 ° C is usually reached.
  • cryogenic gas liquefied or gaseous
  • cryogenic air is used as the cooling medium.
  • Nitrogen or carbon dioxide are preferably used as the cryogenic gases.
  • the cooling medium absorbs heat from the refrigerated goods and thereby cools them down.
  • the atmosphere in the cooling system usually an air atmosphere, more rarely a protective gas atmosphere, is also cooled.
  • the water content of this atmosphere i.e. the air humidity, as well as moisture that is released from the refrigerated goods (e.g. food or pharmaceuticals)
  • the atmosphere i.e. the air humidity, as well as moisture that is released from the refrigerated goods (e.g. food or pharmaceuticals)
  • the atmosphere i.e. the air humidity
  • moisture that is released from the refrigerated goods e.g. food or pharmaceuticals
  • the object of the invention is therefore to improve the removal of water ice from cooling systems and, in particular, to enable the removal of water ice without interrupting the operation of the cooling system.
  • the object is achieved in that the water ice is sucked out of the interior of the cooling system using a suction fan and at least one suction nozzle. At least three suction nozzles are preferably used.
  • the water ice of one is particularly preferred with the aid of the suction nozzle
  • Extracted conveyor belt on which the refrigerated goods are transported through the cooling system is advantageously ensured by the suction of water ice deposited there. Blocks of movement of the conveyor belt caused by the water ice can thus be avoided.
  • the suction nozzles are moved, in particular pivoted, during the suction.
  • the effect of the suction can be made available with the same quality everywhere, even with a small number of suction nozzles, with particular advantage for the entire conveyor belt and / or for the entire interior of the cooling system.
  • the object is achieved in that at least one suction nozzle for water ice is provided in the interior of the cooling system and is operatively connected to a suction fan. At least three suction nozzles for water ice are preferably provided.
  • the suction nozzles are particularly preferably arranged in the cooling system in such a way that the water ice is sucked off by a conveyor belt on which the refrigerated goods are transported through the cooling system.
  • the suction connections are movable, in particular pivotable, fastened inside the cooling system.
  • the water ice is advantageously removed without interrupting the operation of the cooling system.
  • Another advantage is that, in contrast to the conventional method of blowing off water ice from certain components of the cooling system, no medium is introduced into the cooling system. This reliably avoids the risk that additional contamination or moisture could be introduced into the cooling system when the water ice is removed.
  • the suction is also carried out without contact, which also helps to meet high hygiene requirements with the present invention.
  • a portion of the atmosphere in the cooling system is also extracted with the water ice.
  • the atmosphere serves as a transport medium (carrier) for the water ice to be extracted.
  • the extracted water ice is removed together with the extracted atmosphere, for example via a pipeline or a piping system or via a hose, and is disposed of outside the cooling system.

Abstract

Procédé et dispositif permettant d'éliminer la glace hydrique d'unités frigorifiques destinées à refroidir des denrées à une température inférieure au point de congélation de l'eau. Selon ledit procédé, la glace hydrique est aspirée hors de l'unité frigorifique à l'aide d'un ventilateur aspirant et d'au moins une buse d'aspiration. A cet effet, le dispositif selon la présente invention comporte au moins une buse d'aspiration de glace hydrique située à l'intérieur de l'unité frigorifique, ladite buse se trouvant en liaison fonctionnelle avec un ventilateur aspirant.
