Definitions

  • the present invention relates to ice making apparatus.
  • the invention is directed to a machine for making flake ice.
  • Flake ice is made in this sheets approximately 1.5-6.0 mm thick.
  • the sheets may be curved or flat and the thin ice is generally broken into random-sized flakes when harvested.
  • Flake ice is particularly suitable for packing products such as fish or frozen foods as the ice flakes can be packed close to the products.
  • flake ice is ideal because the flakes present the maximum amount of cooling surface for a given amount of ice.
  • Flake ice is commonly produced by the application of water to the inside or outside of a refrigerated cylindrical drum.
  • the water is applied at a first angular location on the drum and adheres thereto in a thin layer by surface tension.
  • the water freezes into a thin layer of ice, which is fractured by an ice removal device at a second angular location downstream from the first angular location in the direction of rotation.
  • the thickness of the flake ice can be varied by adjusting the speed of the rotating drum, varying the evaporator temperature, and regulating the water flow on to the freezing surface. Since flake ice can be made in a continuous operation without being interrupted for a harvest cycle, less refrigeration tonnage is required to produce a tonne of ice than any other type of manufactured ice when similar make up water and evaporating temperatures are compared.
  • the ice removal device is located only on the side of the drum on which ice is formed, the continual unbalanced force applied to that side of the drum to fracture the ice from the freezing surface accelerates the wear on the drum bearings.
  • a further disadvantage of known ice making machines of the drum type is that their capacity cannot be readily increased. If increased capacity is desired, it is usually necessary to install a whole new machine. That is, in addition to installing an extra refrigerated drum, it is also necessary to install another refrigeration unit including motor, compressor and condensor, and a new drive unit. Any upgrading in capacity will therefore involve considerable expense.
  • GBA-1460095 (and equivalent US-A-3863462) describes a large scale flake ice producing machine which comprises one or more upright refrigerated discs rotatable on a horizontal shaft. Water or other congealable liquid is applied to both surfaces of the disc and frozen into sheets of ice as the disc rotates. Thereafter, the sheets are removed from the disc in ice flakes.
  • Each disc is approximately 1.8m in diameter and comprises a pair of large round aluminium plates spaced apart about 20mm and sealed at their periphery to form an enclosed space. Baffles are placed within the interior of the space to form rudimentary passages through which a coolant is pumped in order to refrigerate the disc surfaces.
  • the liquid applied to the disc member is water which is frozen to form ice.
  • the ice is removed in the form of flake ice as hereinbefore described.
  • the water may be applied to the surface of the disc by rotating the disc through a water trough or the like. Alternatively, the water may be sprayed onto the disc.
  • the ice removal means comprises a pair of harvesting blades juxtaposed with, and extending radially along respective opposite sides of the disc.
  • Each harvesting blade does not contact the disc but is spaced therefrom by a small clearance, typically 0.05 - 1.0mm. The ice is removed without introduced heat.
  • each point on the operative surfaces of the disc wil undergo the following steps in sequence: (1) water will be applied to the disc surface, (2) the water will freeze into ice as the disc rotates with time, (3) the ice will be removed by the ice removal means, and the above sequence is repeated with each revolution of the disc in a continuous process.
  • the ice making apparatus is able to utilize direct expansion refrigeration with a "boiling" or evaporative refrigerant thereby enabling higher efficiency and freezing capacity to be achieved. Only one refrigeration system is required, the disc(s) constituting the evaporator of the refrigeration system.
  • the disc is of sandwich or laminate construction comprising two halves in which open channels have been etched or machined in patterns which are mirror images of each other.
  • opposed open channels form closed internal channels.
  • the pattern of the channels is such that they extend over substantially all of the plane of the disc and are substantially of equal length so that the disc is cooled evenly.
  • the refrigerated disc has a central aperture having a collar fitted therein. On one side, the collar receives a hollow shaft delivering the compressed refrigerant.
  • the collar has a series of radial bores, communicating at their inner ends with the hollow shaft. At their outer ends, the radial bores communicate with respective inlets to the channels extending through the disc, the channel inlets being located on the cylindrical surface of the disc aperture.
  • the liquid refrigerant passes through the hollow shaft and into the internal channels of the disc whereat it evaporates to thereby cool the disc.
  • the channel outlets communicate with another hollow shaft on the opposite side of the collar via a second set of radial bores in the collar.
  • the evaporated refrigerant is extracted through this hollow shaft to the compressor.
  • the disc, collar and shifts form a single assembly which is rotated by a motor using a belt or chain drive to a pulley or sprocket on one of the shafts.
  • the disc can be rotated in any other suitable manner.
  • the disc can be provided with a toothed perimeter so that the disc can be driven by a cog-wheel gear, either directly or chain-driven.
  • a number of discs are mounted on a common shaft and refrigerant is fed to the channels in each disc via a distributer and pipe lead system.
  • the discs are fed in parallel, and the lengths of the pipe leads are made substantially equal to ensure equal pressure drop in the refrigerant feed to the discs.
  • the evaporated refrigerant can be extracted via the common hollow shaft.
  • the ice making machine 10 of a first embodiment of the invention comprises a frame 12 on which are mounted a water reservoir 11 and a pump 13. Water from the reservoir 11 is pumped by pump 13 through upwardly extending pipe 14 to a pair of water sprays 15 located above and on respective sides of a rotating refrigerated disc 20. The water sprays are oriented to direct water onto both surfaces of the disc to thereby leave a film of water adhering to both disc surfaces.
  • the disc 20 rotates in the direction indicated by the arrow in Fig. 1 and is driven by motor 16 via a belt or chain 17 and pulley 8. However, the disc 20 may be rotated by any other suitable means.
  • the disc 20 may be provided with a toothed perimeter and driven by a cog-wheel gear either directly or by chain.
  • the refrigerated disc 20 has a plurality of channels therein and constitutes the evaporator in a refrigeration circuit.
  • the mounting of the refrigerated disc 20 is shown in more detail in Fig. 3.
  • the disc 20 has a central circular aperture having a circular collar 22 inserted therein.
  • the collar 22 receives a hollow shaft 18 delivering refrigerant while on its other side, the collar 22 receives another hollow shaft 21 for removing the evaporated refrigerant.
  • the shafts 18, 21, collar 22 and disc 20 are fixed relative to each other and rotate as a single assembly. To enable rotation, shaft 18 is mounted in bearing 25 while shaft 21 is mounted in bearing 23.
  • the bearings 23, 25 are located in respective bearing blocks which preferably are adjustably and removably mounted within the frame 12 of the ice making machine.
  • Hollow shafts 18 and 21 communicate respectively with the condensor and compressor (not shown) of a refrigeration circuit.
  • O-rings 26, 24 are provided to seal the connections to the shafts 18, 21 respectively.
  • Shaft 21 has attached thereto a pulley, sprocket or cog which is rotated by motor 16 via belt or chain 17. Rotation of the pulley 8 in turn rotates the disc/collar/pipe assembly.
  • the refrigerated disc 20 is shown in more detail in Figs. 4-6.
  • the disc 20 is of laminated construction and comprises two discs 20A and 20B sandwiched together.
  • Each disc 20A, 20B has a pattern of open channels 30A formed in a surface thereof, for example by etching or machining.
  • the channel patterns are mirror images of each other so that when the discs 20A and 20B are bonded together, closed channels 30 are formed.
  • the disc is typically 4-10 mm thick, and the channels are typically 3.5 mm wide x 2.5 mm high.
  • the channel pattern for a quadrant of the disc 20 is shown in Fig. 4.
  • the pattern for the bottom right quadrant is the inverse to the illustrated pattern for the top right quadrant, and the patterns for the top and bottom left quadrants are mirror images of the patterns for the top and bottom right quadrants, respectively.
  • the channel pattern is so designed that
  • the illustrated disc is composed of two layers, more than two layers can be used to form the laminated disc if desired.
  • Each channel 30 has an inlet 31 communicating with the central aperture in the disc.
  • the outlets of the channels 30 are also located on the inner cylindrical surface of the disc, on the opposite side to the inlets.
  • the collar 22 has a plurality of radial bores 27 on one half which communicate at their inner ends 32 with the hollow shaft 18 and at their outer ends with the inlets 31 of the channels 30 in the disc 20.
  • the collar 22 is provided with a plurality of radial bores 29 having outer ends communicating with the outlets 33 of channels 30 and inner ends communicating with axial bores 28 which, in turn, communicate with the hollow shaft 21.
  • Condensed liquid refrigerant is fed via shaft 18 through radial bores 27 in the collar 22 and into the channels 30 in the disc 20 where it evaporates to cool the disc.
  • the evaporated refrigerant is drawn from the channel outlets 33 through bores 20 and 28 and out through the hollow shaft 21 to the compressor (not shown) in the refrigeration circuit. In this manner, the disc acts as the evaporator in the refrigeration circuit.
  • ice removal means 40 are mounted on frame 12 for fracturing the ice formed on the disc from the refrigerated surfaces. After being broken off the disc, the ice falls down chute 50 to be collected in ice bin 51.
  • harvesting blades 52 are fixed to the bottom edge of a respective one of a pair of radial arm members 53 which in turn are fixed to support plate 51 which is fastened by bolt 59 to cross beam 56 in the frame 12 of the ice making machine.
  • the inner ends of arms 53 are supported by pendant arm 54 which is pivotally attached to bracket 55 on the machine frame.
  • the harvesting blade assembly shown in Figs. 9 - 11 also comprises a bearing block 58 held between a pair of brackets 57 to maintain correct relative alignment between the disc 20 and the working edges of the harvesting blades 52.
  • the harvesting blade assembly is of simple economic construction yet is easy to adjust and to maintain. Moreover, the harvesting blade assembly harvests the ice on both sides of the disc 20 at the same angular location so that the forces on the disc are balanced.
  • the ice making machine of the present invention can be made more compact than known drum machines in which ice is formed on only one side of the drum. Moreover, as the freezing surfaces of the disc are in close proximity to the refrigerant, greater efficiency is achieved. The ice making machine has few moving parts, thereby requiring less maintenance than existing machines. In the event that maintenance is required, the disc/shaft/bearing assembly shown in Fig. 3 can easily be removed from the bearing mounts in the machine.
  • the machine can be started and stopped intermittently and the speed of the disc can be varied to produce products of different clarity and consistency.
  • a single 500 mm diameter disc can produce over half a tonne of ice in a twenty-four hour period.
  • the multi-disc ice making machine of the invention comprises a number of refrigerated discs 70 mounted on a common hollow shaft 71.
  • the shaft 71 is mounted at its ends on combined bearing and seal assemblies 65.
  • An inlet port 68 is provided at one end of the hollow shaft 71 for connection to a source of condensed liquid refrigerant, while the opposite end of the shaft 71 has an outlet port 67 for a suction connection for the evaporated refrigerant.
  • the discs 70 constitute the evaporator of a refrigeration circuit in a similar manner to the embodiment of Figs. 1 to 11.
  • the discs 70 are mounted in a water tank 69, which typically is made of stainless steel or glass reinforced plastic.
  • the tank 69 is mounted on a base 61, which is suitably made of cast aluminium alloy.
  • Spaced pairs of flanges 72 are formed on the tank 69, each disc 70 passing between a respective pair of flanges 72.
  • Scraper blades 75 are provided at the top of respective flanges 72 for fracturing the ice sheet formed on the discs 70 as the discs rotate past the blades.
  • the discs 70 and shaft 71 are rotated by a pulley or sprocket 64 coaxially mounted on the shaft 71 and driven, by chain or belt, by a drive motor 63 via a reduction gear box 62.
  • a pulley or sprocket 64 coaxially mounted on the shaft 71 and driven, by chain or belt, by a drive motor 63 via a reduction gear box 62.
  • the pulley or sprocket 64, or one or more of the discs 70 may be provided with a toothed circumference and driven directly by a cog-wheel gear.
  • the tank 69 is filled with water to the level 80 as indicated in Fig. 13. As the disc 70 moves through the water in tank 69, a film of water will adhere to both surfaces of the disc due to surface tension. As the refrigerated disc 70 rotates in the clockwise direction as shown, the water adhering to the refrigerated surfaces of the disc will freeze to form a thin sheet of ice which is subsequently fractured from the disc surface by scraper blades 75 positioned as shown. Any water not adhering to the surface of the disc 70 or not being frozen will simply trickle back into the tank 69. Accordingly, there is little wastage of the liquid to be frozen.
  • Ice production can be increased by reducing the temperature of water in tank 69 to close to freezing point, increasing the speed of rotation of disc 70 and increasing the flow of refrigerant through the disc 70.
  • each refrigerated disc is substantially as hereinbefore described with reference to Figs. 4-6.
  • Each scraper blade 75 is removably mounted on top of its respective flange 72 by suitable fasteners through holes 77.
  • Each scraper blade 75 comprises a series of teeth 76 for fracturing the sheet ice from the refrigerated surfaces of the discs 70.
  • the scraper blades are hardened and tempered to resist wear. The only substantial wear in the machine is the abrasion of the ice against the scraper blades, and the scraper blades 75 can easily be removed for replacement and/or resharpening.
  • a four-way liquid refrigerant distributor is provided at the inlet port 68 of the hollow shaft 71.
  • the four-way distributor comprises four copper distributor tubes 81-84 which communicate with the channels in respective discs 70.
  • the lengths of the distributor tubes 81-84 from the inlet port 68 to their respective discs ?0 are made equal in order to obtain equal pressure drop in the refrigerant feed to each disc.
  • each distributor tube 81-84 is received in a radial bore in a respective collared portion of the hollow shaft 71 on which an associated disc 70 is mounted.
  • Each disc 70 is mounted to a collared portion by means of a clamping ring-nut 78.
  • An internal elliptical bore is formed in the centre of each clamping ring-nut 78 to provide an inlet chamber 73 between the delivery end of the respective delivery tube 81-84 and the channels in the associated disk.
  • Refrigerant delivered through tubes 81-84 fills the receptive chambers 73 which communicate with the channel openings 31 of each respective disc 70. Refrigerant flows through the channels 30 of each respective disc whereat it is evaporated to cool the discs.
  • the evaporated refrigerant is extracted via the channel outlets which communicate with a suction chamber 74 formed between the shafts 71 and the disc 70 by the elliptical aperture in the clamping ring-nut 78.
  • the suction chamber 74 communicates with the interior of the hollow shaft 71 via slots 79 cut into the shaft 71.
  • the refrigerant is extracted from the interior 80 of the hollow shaft 71 via the outlet port 67 for delivery to the compressor of the refrigeration circuit.
  • the ice making machine may use a disc of other shape such as hexagonal or octagonal.
  • the construction of the disc can be varied to include more than two layers bonded or brazed together.
