Definitions

  • the invention relates to an apparatus and a method for freezing a food with a liquid consistency according to the preambles of claims 1 and 2.
  • liquid foods such as sauces, juices or milk events, in particular milk, yogurt, buttermich, kefir or curd, are used for the preparation of dishes or drinks. They can be frozen to make them more durable.
  • the freezing or freezing of foods of liquid consistency has the disadvantage that after freezing, the respective portion is present in a correspondingly large piece, which is predetermined by the size of the container holding the food. If only a small amount of the food is required, either the piece must be cut up in the frozen state or the entire piece must be thawed. The excess amount of thawed food can often no longer be used and must therefore be disposed of.
  • the method according to the invention with the characterizing features of claim 1 and the device according to the invention with the characterizing features of claim 2 have the advantage that the food of liquid consistency is frozen and that individual pieces of the food are produced in frozen form. These pieces can be easily portioned and packaged. They can be added in the desired amount to the dish, pastry or drink to be produced. Since the food is not in one large but in many small pieces, it can be thawed quickly without the need for heat. It is also suitable for long-term storage. Spices or other ingredients can be added to the food before freezing.
  • liquid foods that are suitable for this include, for example, mixtures of egg white and egg yolk, milk products, sauces or juices. These are freshly prepared or prepared and then frozen. In this state, they can be kept for a long period of time and are always freshly available in the required amount if required.
  • the device according to the invention for freezing the food of liquid consistency consists of a cooled, rotating roller which has a temperature on its surface which is sufficient for freezing the food.
  • This roller is rotatably mounted in a tub in which the liquid food can be filled.
  • the surface of the roller dips into the liquid food in the lower area. Due to the low temperature of the roller, the food freezes on the surface.
  • the frozen part of the food is carried along when the roller rotates and separated from the roller by a scraper, which is preferably arranged on the upward-facing side of the device. This scraper exerts a force on the surface of the roller and thus on the frozen layer. This is directed tangentially to the surface of the jacket and ensures that the frozen layer is lifted off. There is no deformation of the evaporator jacket.
  • the frozen layer of the egg mixture When detached from the surface of the roller, the frozen layer of the egg mixture bursts into larger or smaller pieces. This piece consists of parts of the layer. Its thickness is determined by the thickness of the frozen layer. This is repeated among others
  • Rotation speed of the roller determined.
  • the pieces are transported away and either collected in a container or fed to further processing or packaging via a conveyor. If the pieces are too large for the intended application or packaging, they can be further shredded.
  • the roller consists of a solid evaporator body, which is made of plastic, for example, and a rigid evaporator jacket surrounding the evaporator body and made of a material with high thermal conductivity. This includes, for example, metal.
  • At least one channel for conducting the refrigerant runs helically in the evaporator body. This is covered by the evaporator jacket. It therefore runs close to the surface of the roller.
  • the refrigerant channel extends from one end region of the roller to the other, so that the roller is cooled over the entire outer surface.
  • the refrigerant is passed through the channel or channels via a refrigeration machine.
  • devices for cleaning or disinfecting all parts coming into contact with the food can be provided.
  • nozzles for spraying with hot steam and cleaning agents or UV lamps can be provided.
  • a control device for controlling and monitoring the drive of the roller and / or the device for cooling can be provided.
  • e.g. B. freezing of the roller or damage to the refrigerator can be prevented.
  • Figure 1 An inventive device for freezing a food with a liquid consistency.
  • a roller 1 is rotatably supported in a trough 2 and is driven in rotation by an electric motor or a gear motor, not shown.
  • the roller 1 consists of an evaporator body 7 and an evaporator jacket 4.
  • the refrigerant channels running on the surface of the evaporator body 7 cannot be seen in the drawing.
  • the lower part of the roller 1 is immersed in a liquid food 3, so that the evaporator jacket 4 of the roller 1 is wetted with the liquid food as it rotates.
  • the liquid food freezes on the cooling surface 4 of the roller 1 cooled by the refrigerator. This forms a thin frozen layer of the food, which is separated from the outer surface with the aid of a fixed scraper 5 and fed to a collecting container (not shown).
  • a float switch 6 is arranged on the side of the tub 2 and is immersed in the liquid food 3.
  • the float switch registers the temporal change in the fill level in the tub 2. If the fill level does not change within a time interval or if it changes more than a predetermined limit value, the control device (not shown) which interacts with the float switch 6 switches the drive for the roller and the refrigerator from.

Abstract

L'invention concerne un procédé et un dispositif pour congeler une denrée alimentaire à consistance liquide, cette dernière étant congelée sur la surface d'un cylindre réfrigéré (1). La couche congelée de la denrée alimentaire est raclée pour être éliminée de la surface du cylindre par une unité de séparation (5). Les morceaux retirés par raclage sont acheminés, dans un contenant ou par l'intermédiaire d'un dispositif de transport, à une station de traitement ultérieur ou d'emballage.
