Definitions

  • the invention relates to a device for producing flake ice from a liquid, comprising a tank receiving the liquid, a rotatably mounted roller which partially dips into the liquid received in the tub, a cooling device for cooling the surface of the roller and a scraper for removing ice formed on the surface of the roller from the liquid.
  • Flake ice made with devices of this type is used in the food industry to cool fresh produce, e.g. Fresh fish or seafood used in the transport or display of a grocery store, or used as ice cream in the production of batters. Due to the direct contact of the flake ice with the food, strict hygienic regulations must be observed.
  • the roller is a part of the refrigerator. Specifically, this roller is an evaporator roller through which a refrigerant flows, in which liquid refrigerant is vaporized with heat exchange with the fluid to be frozen.
  • the evaporator roller thus forms the evaporator of the refrigeration circuit of the refrigerator.
  • the known device proves to be problematic insofar as it must be avoided in any case that the refrigerant, which is usually food incompatible, comes into contact with the liquid to be frozen. Thus, in particular in the area of the roller and its bearings, high demands are placed on the tightness of the refrigerant circuit.
  • the invention has for its object to provide a device for producing flake ice, which is producible and operable with a lower economic cost and in which in particular the risk of contamination of the flake ice is minimized by refrigerant.
  • the object is achieved by a device having the features of claim 1 and in particular by the fact that the roller is part of a closed coolant circuit, which is in heat exchange relationship with a closed refrigerant circuit of a refrigerator.
  • the invention is based on the general idea that the roller is not part of the refrigerating machine, i. as an evaporator, but to connect the roller indirectly, namely via a separate refrigerant circuit, with the refrigerator, so that the roller does not come into contact with refrigerant. Instead, the roller is only flowed through by a refrigerant, which can not mix with the refrigerant, but only heat exchanges with this.
  • the use of refrigerant can be limited to a central refrigeration cycle of the chiller. This allows a reduction in the refrigerant charge, the realization of higher ice capacity with lower legal requirements for design and operation, the spatial separation between refrigeration, ie chiller, and consumers, ie roller, the possibility of using all existing refrigerant and the possibility of connecting the device to existing refrigeration circuits.
  • the refrigerant of the refrigerant circuit which flows through the roller, and the refrigerant of the refrigerator to different substances.
  • the coolant also takes over a memory function and thus can compensate for load fluctuations.
  • the roller does not need to withstand high internal pressures, which simpler roller designs come into question.
  • the device not only ensures increased food safety, but can also be produced and operated overall with less economic outlay.
  • a particularly simple and cost-effective construction of the roller provides, for example, that the roller comprises a core and a jacket, wherein the jacket surrounds the core and a flow channel for the coolant between jacket and core is formed.
  • the flow channel may have the shape of an annular gap between the shell and the core. The brine flowing through the annular gap is fully in contact with the inside of the shell, whereby the shell is cooled and heat is removed from the liquid to be frozen.
  • a means for increasing the contact surface between the refrigerant and the roller in the flow channel may be provided, e.g. an open-pored metal foam, which is penetrable by the refrigerant.
  • the roller is suspended on two retaining arms.
  • the roller can be rotatably mounted on the holding arms by means of axle stubs formed on the end faces of the roller.
  • the suspension of the roller to the support arms allows an independent of the roller arrangement of the tub, whereby the assembly or disassembly of the tub, for example for cleaning or maintenance purposes, is greatly simplified.
  • the scraper or a liquid inlet for introducing the liquid to be frozen in the The tub is not mounted on the tub or at least releasably connected to the tub to facilitate the installation and removal of the tub.
  • the trough may comprise two side parts and a base part, which connects the two side parts releasably or non-detachably.
  • the base part In the installed state of the tub side panels can lie in two planes perpendicular to the axis of rotation of the roller.
  • the base part preferably extends parallel or at least approximately parallel to the axis of rotation of the roller.
  • the tub can, for example in one piece, be formed from a plastic material.
  • the well may be a metal material, such as e.g. Stainless steel or steel, or have a composite material.
  • the side parts and the base part of the trough are formed as separate components, it is advantageous if the side parts have sealing elements which extend at least along a partial circumference of the side parts and provide a sealing engagement between the base part and the side parts.
  • the side parts may be provided with a groove extending over at least part of the circumference for receiving the sealing elements, the sealing elements preferably assuming a clamping fit in the groove so that they remain in the groove when the base part is removed.
  • the base part rests with its lateral end regions on the end faces of the side parts.
  • the base part can be fixed by means of a clamping device on the side panels.
  • the side parts preferably have a substantially round or oval outer contour, while the base part in the planar projection has a substantially rectangular basic shape.
  • the tub can be fastened with its side parts from the outside to the support arms.
  • the scraper can be independent of the tub, for example, on a crossbar mounted so that it remains when removing the tub on the crossbar and is freely accessible from the outside to be cleaned and / or disinfected or disassembled.
  • an inclined plane is provided, via which the ice removed by the scraper from the roller is discharged.
  • the inclined plane covering fasteners for the scraper, to prevent the fasteners come into contact with the flake ice.
  • At least one liquid inlet may be provided to allow the liquid to be frozen, e.g. from the top, into the tub to initiate.
  • the liquid inlet has at least one outlet opening for the liquid, which is located below the scraper.
  • the liquid inlet may have at least one outlet opening, which is located between one of the two end faces of the roller and a side part of the trough.
  • a liquid application device which directs the liquid directly onto the jacket the roller applies.
  • the liquid application device may be provided as an alternative or in addition to a liquid inlet and be arranged, for example, above the roll axis, so that the liquid is applied from above or obliquely from above onto the roll.
  • the liquid applicator preferably extends over substantially the entire length of the roller.
  • the liquid application device is advantageously mounted independently of the trough.
  • a pump may be provided to draw liquid from the trough and to pump it to the roll via the liquid applicator.
  • the tub may be at least partially coverable with a cover to which the liquid inlet can be detachably or fixedly arranged.
  • a cleaning device for cleaning the trough and the roller, which preferably comprises a plurality of nozzles for spraying the roller and the trough with a cleaning agent, e.g. a cleaning liquid having.
  • a circulation device may be provided to generate a flow in the cleaning liquid in the tub, by which the cleaning result is improved.
  • the circulation means may comprise a circulation pump, e.g. a submersible pump, which sucks the cleaning liquid from the tub and promotes back into the tub.
  • the circulation device may comprise an agitator, which causes a flow of the cleaning liquid in the tub.
  • the agitator may comprise a separately driven shaft with at least one axially or radially conveying stirrer and / or by at least one formed on the roller, in particular on an end face of the roller, formed stirrer.
  • the supply of cleaning liquid in the tub is carried out according to a simple structural design on the inlet, through which the liquid to be frozen is introduced into the tub. Accordingly, the cleaning liquid can be drained after a cleaning process by a drain from the tub, which is also provided for draining the liquid to be frozen.
  • a system control which detects the operating and / or service life of the device, to conclude from this on a hygiene state of the device and to trigger a cleaning process when reaching a critical hygiene state, which either started automatically or manually after appropriate signaling by a user can be triggered.
  • the roller preferably has an inlet channel for the coolant at its one axial end and an outlet channel for the coolant at its other axial end. This allows a flow through the roller through the coolant over substantially the entire extent of the roller seen in the axial direction, which is referred to here as the length of the roller.
  • the inlet and outlet ports each include a blind bore extending axially into one of the axle stubs of the roller.

  • a closable drain 14 is formed, through which the liquid 12 can be drained from the tub 10 for cleaning purposes.
  • a substantially cylindrical roller 16 also referred to as Eistommel, horizontally arranged such that it partially immersed in the liquid 12.
  • the shell 18 of the roll is heated by means of a cooling device 20 (explained in more detail below).
  • Fig. 2 cooled down to the freezing temperature of the liquid 12 or even lower temperature.
  • the low temperature of the jacket 18 causes liquid 12 to freeze on the shell 18 and forms an ice layer 22 thereon.
  • the ice layer 22 is rotated by the roller 16 about its cylinder axis, in Fig. 1 in the direction indicated by the arrow 24 rotation direction, scraped off by a scraper 26 of the roller 16 and fed as Scherbeneis 28 for further use.
  • FIG. 2 shows the provided for cooling the jacket 18 cooling device 20 two separate self-contained refrigerant circuits, namely on the one hand a refrigerant circuit 30 to provide the desired low temperature and on the other a refrigerant circuit 32, through which the cold generated by the refrigerant circuit 30 to the cold cold 16 is transported.
  • the refrigerant circuit 30 comprises a throttle body 34, a heat exchanger 36, e.g. Plate heat exchanger, trained evaporator, a compressor 38 and a condenser 40 and thus forms a known refrigeration machine in which the circulating refrigerant between gaseous and liquid state switches back and forth.
  • the refrigerant circuit 32 is coupled via the heat exchanger 36 to the refrigerant circuit 30, so that a circulating in the refrigerant circuit 32 brine, e.g. a brine, with the refrigerant of the refrigerant circuit 30 exchanges heat and thereby cooled down to the desired temperature.
  • the cooled brine is pumped through the roller 16 by a pump 42 to cool the jacket 18 to the desired low temperature and to freeze the liquid 12 by removing heat from the jacket 18.
