Definitions

  • the object of the present specification is a vertical evaporation device, the main distinguishing feature of which lies in the creation of ice starting from a vertical panel with a grid of dividers and flanges folded on the four sides thereof joined to a tube coil, by means of a system with freezing and detachment cycles.
  • Spanish patent ES 0 035 798 which describes a simplified evaporator made up of an evaporating element as such and of an exchanger element for changing the temperature of gases.
  • the evaporator element consists of two U-shaped tubes joined to each other; the respective loops and welds being in contact with each other, and the ends of two adjacent branches connecting to form a single conduit.
  • One end of the exchanger element is in front of the other two free branches of the U-shaped portions, the external one being joined to the central tube of the exchanger and the other branch to the external wide tube of the exchanger.
  • the other end of the exchanger which should be a little lower, has one outlet for the central tube and another for the external tube.
  • One or more branches of the U-shaped portions can be provided with flaps.
  • a thin tube reaches and rests on the far end of the external tube of the exchanger and continues along it, welded on the surface if appropriate, and when it reaches the other end of the exchanger it is then grafted into the starting portion of the branch of the U-shaped portion joined to the central tube of the exchanger.
  • a device in that place must let the gas coming from the central tube of the exchanger pass and prevent the liquid coming from the thin tube from falling therein.
  • the vertical evaporation device object of the present specification comprises an evaporator made of a vertical panel with a grid of dividers and folded flanges on the four sides thereof, attached to a refrigerating tube coil by the rear portion thereof and both being embedded in a framework as a support, which, in turn, houses a water distributor with three input channels joined to the upper side of the device by means of clipping.
  • the recommended set will enjoy a series of advantages such as a robust and hygienic assembly, since all the tubes, bolts, nuts and anchors of the system are hidden; in addition to easy installation and disassembly without tools thanks to the snap-fit system used, which in turn facilitates cleaning and maintenance tasks.
  • inlet channels to the distributor will enable a continuous and uniform sheet to be obtained on the evaporator with the minimum amount of water possible, which will prevent empty or incomplete cubes from being obtained throughout the process, in addition to water losses and/or splashing.
  • the fact that there is a difference in refrigeration performance between the inlet and outlet of the coil implies that the shape thereof, whether the shape is the one compensating it, thus obtains an ice slab with uniform thickness throughout the surface of the evaporator, which will cause the detachment of the ice to be simultaneous in all the area thereof and the slab will be demoulded parallel to the evaporator.
  • the vertical evaporation device is characterised in that it comprises an evaporator (1) made by means of a vertical panel with a grid of dividers (1a) and flanges folded on the four sides (1b) thereof joined to a refrigeration tube coil (2) on the rear portion thereof and both being embedded in a support framework (3), which in turn incorporates a water distributor (4) with three inlet channels (4a) which is joined by means of clipping to the upper side (1b) of the device.
  • the evaporator (1) recommended herein will be made of copper coated with chemical nickel.
  • the grid of dividers (1a) will determine the size of the ice cubes.
  • the support framework (3) will be made of a series of plastic ends which are screwed to the evaporator (1) by means of bolts, and the function of which will be to fasten the evaporator (1) to the frame of the machine in a robust manner and in position; acting as a thermal barrier in the edge of the evaporator (1), anchoring the water distributor (4), and finally, ensuring a uniform flow of water in the inlet of the evaporator (1), in the outlet to the tank and in the rear portion towards the coil (2).
  • the water distributor (4) has a channel intended for the inlet of the water into the device (4b), lower flaps intended to slow down the water speed, a second channel intended to distribute the water in the grid of dividers (1a), and a third channel intended for the inlet of new water for the next cycle.
  • the refrigeration tube coil (2) will be pressed beforehand, flattening the exposed face thereof, in order to favour thermal transmission.
  • the grid of dividers (1a) is tilted in order to favour the sliding of the plate when performing the demoulding.
