Definitions

  • This invention relates to an apparatus for the production of ice and similar products.
  • the devices for the production of fine or crushed artificial ice, granulated ice, ice flakes, ice snow and the like are used in all kinds of food and non-food sectors, and shall be able to produce ice either using fresh drinking water or other food liquids or sea water.
  • such devices for the production of artificial ice are used on boats or fishing vessels where ice is highly requested, therefore they must be extremely reliable and have a compact, not very bulky structure.
  • German patent No. 870 551 and the German patent No. 951 517 disclose a procedure and a device for the production of ice having a pivoting cylinder drawing in a tank containing the liquid to be frozen.
  • the cylinder is cooled internally by means of a refrigerant and on its cylindrical surface it is provided with a scraping device to remove the ice layer forming on the surface of the cylinder itself.
  • the surface of the cylinder has a number of channels or tubular guides to channel the refrigerant, which are helicoidally positioned on the surface of the cylinder.
  • the device for the production of ice includes also the cylinder supporting shafts which are co-axial and associated respectively to the opposed plane faces of the same.
  • Such shafts are axially perforated and associated, respectively, one to the supply duct of the refrigerant and the other to an outlet duct of the refrigerant, after the latter has flowed through the cylinder and has cooled it. From what has been said, you can easily understand that it is rather expensive and complex to make, for instance, the seals between the rotating parts and the fixed parts of the device described above, therefore, as a result of the high number of seals used, in the long run leaks occur between rotating and fixed parts of the device, which affect the performance of the device for the production of ice.
  • the fact that the refrigerant inlet and outlet are located on the two opposed plane faces of the cylinder involves that the driving members of the same shall be housed in areas far from the cylinder and, sometimes, even outside the framework bearing the same so that the dimensions of the device for the production of ice increase considerably with problems of coupling, for example, between the speed reducer, the cylinder driving motor and the cylinder itself.
  • the object of the present invention is to overcome all the above-mentioned drawbacks by making an apparatus for the production of ice and similar products having very little dimensions and at low costs thanks to the considerably reduced wear of all its mechanical parts.
  • a relevant object of this invention is to make an apparatus for the production of ice and similar products where the occurrence of any leak of refrigerant does not affect the performance of the machine.
  • Another important object of the present invention is to make an apparatus for the production of ice and similar products where the speed reducer and the cylinder driving motor can be directly mounted on the supporting frame of the same.
  • an apparatus for the production of ice and similar products including a tank containing a liquid to be frozen internally defined to a bearing framework of a cylinder pivoting around its own axis and drawing with one of its portions in said tank, said cylinder being cooled by a refrigerant through a supply duct and a return duct associated to the same, there being provided also a device scraping the ice layer formed on the sleeve of said cylinder, driving means of said cylinder, and a circuit cooling said fluid, characterized in that said inlet and outlet ducts of said refrigerant are both connected on one face of said cylinder.
  • the apparatus for the production of ice and similar products in accordance with this invention is shown globally with the reference number 1 and includes: a tank, generally shown as 2, containing a liquid to be frozen such as, for example, water, salt water or any food liquid to be frozen.
  • the tank 2 is defined by a bearing framework 3 appropriate for supporting pivotably around its axis a cylinder 4 drawing with one of its lower portions inside the liquid to be frozen.
  • the cooling of the cylinder takes place in a well-known way and, namely, by means of an inlet duct 5 and an outlet duct 6 which are advantageously associated both on one face 7 of the cylinder 4.
  • the cylinder 4 suitably made of an aluminium alloy, includes a sleeve 8 of stainless steel to strongly resist to corrosion and, therefore, to allow the apparatus to work also with salt water such as sea water.
  • the sleeve 8 is also laterally welded to the faces 7 and 9 of the cylinder 4 so that the latter turns out to be suitably made of only one piece.
  • the cylinder 4 includes internally a channel, globally shown as 10, the inlet 11 of which and its outlet 12 are associated to the supply and return ducts 5 and 6 respectively.
  • the channel 10 extends with its part 13 inside the cylinder and with its part 14, having a helicoidal development, on the peripheral surface of the same.
  • the driving means include a speed reducer of a well-known type associated, as already mentioned, to the cylinder 4 on the other side of the supply and return ducts.
  • two speed reducers are shown as 17 and 18, which are applied to the cylinder 4 and have various dimensions according to the type of ice that you want to obtain.
  • the driving means include also a motor assembly 19 associated to said speed reducer, which can be advantageously connected as well by means of an adjusting bracket 20, to the bearing framework 3 to make an extremely compact, functional and simple structure.
  • a chamber is located inside the tank 2 communicating with the latter, internally provided with a floating device, not shown in the Figure and of a well-known type, which keeps the level of the liquid to be frozen constant inside the tank.
  • the framework 3 includes also a wall 21 which is made in a manner suitable to define the scraping device 22 developing inside the tank 2 over the cylinder 4.
  • the wall 21, and thus the scraping device 22 is adjustable when approaching and/or moving away from the sleeve of the cylinder 4 so to adjust its upper end 23 having a tapered configuration in order to better exercise its function of ice-scraper.
  • the refrigerant circulating inside the cylinder 4, reduces its temperature so that the thin layer of water or of any other fluid which deposits on the sleeve of the same freezes by draft and as a result of the rotation of the cylinder 4 it arrives in front of the scraping device 22 which detaches it as flakes and channels it for processing.
  • the apparatus proves to be extremely functional, simple and compact and, therefore, suitable for being used also in extremely small spaces such as boats and the like.
  • any material can be used and any dimensions can be selected according to the needs and to the state of the technique.
