Definitions

  • This invention relates to icemaking apparatus and more particularly to an improved icemaking unit which is suitable for use in an ice dispensing unit where ice delivery is required at a location remote from the icemaking unit or in a soft drink vending machine of the type which charges a controlled amount of flaked or chipped ice directly into the drinking cup.
  • the conventional prior art arrangement has a number of disadvantages.
  • the evaporator-freezing unit is large and relatively heavy so it requires a spaceconsuming supporting structure to hold the freezing unit in the upper portion of the enclosure or housing. Maintenance is made more diflicult with the compressor and condenser in one section and the evaporator in another, often hidden behind a maze of other components.
  • the improved icemaking apparatus described herein comprises an arrangement whereby the ice is formed in a first zone and transferred through a conduit to an ice delivery means adapted to discharge ice into a receiver in a second zone located either above said first zone or in a position where the ice will not readily flow to the second zone by gravity alone.
  • the conduit connecting the ice forming means to the receiving zone is sized in relation to the dimensions of the ice so that the ice is advanced through the conduit solely by the force of additional ice being delivered from said ice forming means.
  • Another aspect of the invention relates to providing a relatively simple, low-cost freezing and extruding unit which is capable of producing a commercially acceptable grade of ice by shearing off a uniform section of the ice formed in the freezer and advancing it through a restriction, whereby the compressive force exerted thereon removes excess water and compacts the ice.
  • Another object of the invention is to provide an improved ice freezing and extruding unit of the internal 3,371,505 Patented Mar. 5, 1968 auger type having a simple, low-cost form of construction.
  • FIGURE 1 is a schematic diagram of an icemaking apparatus embodying the principles of the present invention
  • FIGURE 2 is a cross-sectional view of the ice freezing and extruding unit
  • FIGURE 3 is a cross-sectional view taken along the plane line 33 of FIGURE 2;
  • FIGURE 4 is a cross-sectional view taken along the plane of line 4-4 of FIGURE 2;
  • FIGURE 5 is a cross-sectional View taken along the plane of line 55 of FIGURE 3.
  • FIGURE 1 is a schematic or diagrammatic illustration of a preferred embodiment of the invention
  • the system comprises an ice freezing and extruding unit 10 and conduit means 14 arranged to conduct ice formed in said freezing and extruding unit to an ice delivery means, which in the example is formed by the distal end of the conduit, discharging said ice into a storage bin or receptacle 12.
  • Refrigeration means are provided for cooling the freezing and extruding unit, said refrigeration means including a compressor 16, a hot gas line 17, a condenser 18, a capillary (or expansion valve) 20, an evaporator 22 surrounding the freezing and extruding unit 10, and a suction line 23 interconnecting the evaporator with the suction side of the compressor.
  • Freezing and extruding unit 10 comprises a casing 24 provided with a freezing chamber 26 having a cylindrical side wall 27 and a vertically extending auger 28 journalled within said freezing chamber and driven by a combination motor and speed reduction unit 30.
  • Water is continuously supplied to the freezing chamber 26 from a reservoir 32 through a conduit 33.
  • a constant level is maintained in the reservoir 32 (and in the freezing chamber) by means of a float valve arrangement 34 controlling the supply of water to the reservoir through inlet 36.
  • any conventional refrigerant such as, for example, refrigerant 12 is discharged under pressure from the compressor 16, through the hot gas line 17 to the condenser 18 where it liquifies. From there it flows through a restriction, such as capillary element 20 or an expansion valve, to the evaporator, which in the present apparatus is formed by the jacket 22 around the freezing chamber 26.
  • the liquid refrigerant under low pressure in the evaporator, boils and extracts heat through the heat conductive walls of the casing 24 to cause a portion of the Water in the freezing chamber 26 to freeze on the cylindrical side walls 27.
  • the auger blades scrape the ice formed on the walls of the freezing chamber and convey it upwardly toward the upper end of the freezing chamber.
  • the ice at this stage is quite watery or slushy owing to the fact that it is in contact with liquid water in the freezing chamber. Consequently, means are provided for extruding the ice through a restriction to compress the excess water out of the ice thereby producing a clearer and more coherent form thereof. This latter arrangement will be more fully described in connection with the construction of the freezing and extruding unit.
  • FIGURE 2 shows the construction and arrangement of the freezing and extruding unit 10 in greater detaiL-It
  • the casing 24 includes a jacket 22 which completely encircles the median portion of said casing to provide an annular space 25 between the jacket and the casing, said space being maintained at suction pressure and constituting the evaporator of the refrigerant circuit.
  • Liquid refrigerant is admitted to the evaporator through inlet port 40 and the refrigerant vapor is exhausted through port 41 to the suction side of the compressor.
  • a vent opening 31 is provided in the upper portion of the casing 24 to facilitate the flow of water into the freezing chamber.
  • the auger 28 is vertically arranged within the casing and journalled in upper and lower anti-friction bearing assemblies 42 and 43 respectively.
  • the upper bearing 42 is retained in position between an upper bearing housing 44 and a cover cap or plate 45 closing the upper end of the casing.
  • the lower bearing 43 is supported within a lower bearing housing 46 which is held in place by a retaining ring 48. Water is prevented from leaking out of the bottom of the freezing chamber by means of an O-ring seal 49 between the bearing housing 46 and the casing wall and a packing member 50 between the auger shaft and the bearing housing.
  • an important aspect of the present invention is the provision of means for shearing off a uniform ribbon of ice and compressing it to remove excess water therefrom.
  • the soft, slushy ice scraped from the inside wall of the freezing chamber is advanced along a restricted path to effect a transformation of the ice into a more compacted and clearer condition. While means for extruding formed ice through a restricted opening are known per se, it is believed that the present design offers significant advantages from the standpoint of fabrication costs, operating efficiency, and uniformity of product.
  • the upper bearing housing 44 includes a downwardly depending sleeve portion 53 and a fiat annular surface 54 extending in plane generally normal to the axis of the auger shaft.
  • a rectangular aperture 56 is provided in the wall of casing 24, said aperture constituting a passage through which ice is extruded into the conduit 14.
  • a preferred embodiment of this element includes a loop portion 61 encircling the upper bearing housing sleeve 53 and an elongated shear blade portion 62 which extends tangentially toward the aperture 56 and is engageable with one edge of said aperture.
  • the shear element need not be in this particular form; for example, this element could be made integral with the bearing housing or may comprise a part of the casing 24.
  • Element 60 is retained in its operative position between annular surface 54 on the bearing housing and an annular surface near the upper end of the auger shaft. While the loop portion is loosely arranged around the sleeve portion 53 of the bearing housing, it is prevented from revolving because the tangentially extending portion 62 projects at least partially through the aperture and engages the peripheral edge thereof.
  • a fitting or connector element 64 having one end shaped in the form of a rectangle, is welded or otherwise secured to the outside of casing 24 over the aperture 56. The other end of the fitting has a generally circular cross-section to permit connection to the tubular conduit 14 leading to the ice receiving and storage bin. This arrangement ensures that the ice, which is extruded through the aperture and has a generally rectangular cross-section, is passed into the conduit 14 with out jamming and clogging the passage. It should be understood that the shape of the discharge aperture is not critical.
  • the auger 28 is provided with at least one complete flight of helical blades 29 which terminate, at their upper ends, adjacent to the shear and guide elment 60.
  • the peripheral or radially outer edges of the auger blades are arranged with a slight clearance (about 0.005 to .010 inch) away from the cylindrical side walls of the casing.
  • the slushy ice is compacted against this surface in the annular space defined between the radially outer surface of element 60 and the side wall of the easing 27 to form an annular-shaped body of ice.
  • this body of ice is caused to move in a circular path through this annular space.
  • the blade portion 62 of element 60 shears off a ribbon of ice from the upper end of the rotating body and guides it tangentially out through the discharge aperture 56.
  • the distance a between the elon gated blade portion of element 60 is narrower than the distance b just ahead of it to provide a restricted passage.
  • the excess water is squeezed out of the rather wet, slushy ice to thereby effect a compaction and clarification of the same.
  • the excess water fiows down into the freezing chamber so that there is no build-up of slush in the discharge throat.
  • the ice is sheared off in substantially uniform pieces with respect to the cross-sectional area thereof.
  • the ice which passes beyond the restriction is in the form of a series of discrete particles having substantially uniform, transverse cross-sectional dimensions.
  • the uniform, predetermined cross-section of this ice makes it possible to pipe the ice through the tubular conduit without jamming.
  • the ice as will be remembered from the previous description, has a rectangular configuration due to the shape of the passage through which it is extruded.
  • the shape and cross-sectional area of the conduit must be selected so that the ice does not jam or wedge in the passage and block further advancement thereof. Accordingly, as best illustrated in FIGURE 5, the diameter of the conduit 14 is only slightly larger than the diagonal distance across the rectangular cross-sectional area of the ice which is designated by the reference character I. In this way, the tendency of a portion of ice to pile up and wedge against ice immediately ahead of it is avoided.
  • the conduit 14 may be made of flexible tubing such as rubber of plastic, and it should be understood that the crosssectional configuration of the conduit is not critical as long as its dimensions conform closely to those of the ice being transported therethrough.
  • the distal end of conduit 14 provides an ice delivery means which obviously may take several forms, i.e. a nozzle, chute, or some other mechanism for guiding the ice into the storage receptacle.
  • an important advantage of this principle is that the ice is in the same form at both the entrance end and the exit end of the transfer or conveying conduit.
  • the ice since the ice is compacted and preshaped into discrete particles having uniform, transverse cross-sectional dimensions before it is introduced into the conduit, it will not disintegrate from the compressive force applied during its passage from the icemaking unit to the storage receptacle. This is particularly important where the amount of external force to move the ice is appreciable.
  • the special characteristics of the ice freezing and extruding unit have special utility in a system where gravity alone is insufiicient to overcome the friction impeding the. movement of ice through the tube, i.e., where some external force on the ice is required to facilitate movement. This condition may occur even when the receiving zone is situated below the level of the icemaking zone, for example, where the storage receptacle is at a considerable distance from the icemaking unit or where the transfer or conveying tube has a number of bends or convolutions.
