Definitions

  • This invention relates to an ice making machine and more particularly to a machine for making ice in the form of small pieces or chunks.
  • the present invention relates to an ice machine that is capable of use in producing sheets of ice and for breaking up the sheets into smaller pieces.
  • the invention is addressed towards the provision of apparatus of the type described which is simple in construction, economical in operation, and which utilizes relatively few moving parts.
  • Another object of this invention is to provide an ice making machine in which the sheets of ice are released from the freezing plates of the machine by the use of relatively warm water which is' later used for ice production thereby to make use of the cold which has been invested in the warm Water for ice removal.
  • FIG. 1 is a diagrammatical sectional elevational view of an ice'making machine embodying the features of this invention
  • FIG. 2 is a plan view showing the arrangement of spray openings on one side of the warm water spray pipe.
  • FIG. 3 is a view similar to that of FIG. 2 showing the opposite side of the spray pipe.
  • the apparatus comprises a pair of substantially identical flat freeze plates 14 vertically arranged in laterally spaced apart parallel relation.
  • the outer surfaces 16 of the respective freezing plates '14 are flat and vertical and in thermally conductive contact with pipes or passages 18 through which there is circulated a refrigerant for use in the freezing of water with which the surfaces 16 are wet. It is preferred to construct the freezing plates 14 of a highly conductive metal.
  • deflector plates 20 which extend continuously upwardly and inwardly from the upper edges of the freezing plates.
  • the plates 20 are welded or otherwise secured ontothe upper edges of the plates 14 in a manner whereby water applied onto the deflector 'plates 20 will flow downwardly and across the freeze surfaces 16.
  • Supported immediately above thejdefiector plates 26 is a distributor pan 22 having upstanding sides and a; bottom wall 24.
  • the pain is preferably formed of a shallow construction and is dimensioned to have a length corresponding to the horizontal dimension of the deflector ice plates.
  • a series of drain openings 26 are provided in the bottom Wall 24 of the pan to elfectan even flow of water from the pan onto the surfaces of the deflector plates 20 in a relatively uniform distribution across the plates whereby the water from the pan flows downwardly from the deflector plates 20 onto the freezing surfaces 16.
  • the Water can he applied in uniform distribution onto the plate 2% ⁇ or directly onto the upper end portion of the freezing surfaces 16 by means of spray pipes 2(2 extending crosswise of the plate 29 in spaced parallel relationship therewith and which is formed with a plurality of spray openings.
  • a distributor pipe 28 which extends crosswise in spaced parallel relationship with the plates 14 and is dimensioned to extend through the lengths thereof.
  • the distributor pipe 28 is provided with a series of apertures or nozzles 30 along the lengths thereof, there being two axially aligned series of such apertures or'nozzles 30, one series being directed towards the left hand plate 14 and the other series being directed towards the right hand plate 14, as viewed in FIG. 1.
  • Means are provided for connecting the distributor pipe 28 to a suitable source of water at about ambient temperature, the temperature in a working embodiment of the invention usually being.
  • the opposite end of the distributor pipe 2-8 is closed whereby water introduced into the open end communicating with the supply source of water will flow into the pipe and out of the nozzles onto the deflector plates 20 and downwardly over the back sides 34 of the freezing plates 14 or directly onto the upper portions of the freezing plates 14 for flow over the back sides.
  • the lower end portions of the freezing plates 14 are provided with drain plates 38 which extend inwardly and downwardly from the lower end of the freezing surfaces 16svhereby water flowing over the surfaces 16, and which has not been congealed during such flow, will follow the surfaces of the drain plates 38'and thus be deflected inwardly and downwardly for flow into a trough 40 located immediately below the ends of the drain plates 38.
  • a water collecting assembly which includes a main tank 44 and an auxiliary tank 46. Both of the tanks 44 and 46 have flat bottoms and upstanding sides with the tank 46' being smaller than the tank 44 and supported within the latter in an elevated position by means of suitable frame pieces 48 and an overflow pipe 50.
  • the tank 44 is made relatively deep so that when it is filled with water, any icy slush in the water will float.
  • the tank 44 is initially filled with water to a suitable level.
  • the refrigeration system is operated for circulation of refrigerant through the pipe 18 to reduce the plates 14 to a temperature below the freezing temperature forwater.
  • the water pump 63 is energized to circulate water from the tank 44 to the distributor pan 22.
  • the water from the distributor pan 22 the freezing plates 14.; That water which does not freeze onto the surfaces 16 will follow thercontour of the plates to be deflected inwardly along thesdrain plates 38f0rflowinto the trough 40.
  • the water drains into the auxiliary make-up tank 46 and through the drain apertures into the main tank 44 for recycling. As the freezing plates 14 cool down, water fiowingiover the sur-.
  • the distributor pipe 28 is formed with alarger-numberof more closely spaced apart openings, or sprays nozzles on one sidethan on the other so that a 'greatervolume of Warming water will :be applied onto one .surfacegby comparison to theother; This will result in more rapid warming of one surface by comparison to the other to effect release of the ice layerfrom one plate before-the other;
  • the specific ratio of openings can be calculated inman -v ufacture to effect the desired time span between releases 7 of the respective ice sheets but it will be sufficient if the number of openings on one side is1.5 to 3 times the num- .ber of openings on the other.
  • the ice is'harvested by first stopping the refrigerant flow through the coils 18' and stopping the operation of the circulating pump-63, and p initiating the operation of thespr'ay pipe 28 to throwwarm water onto the back side of the plates.
  • the water flows I downwardly over the back sides 34 of the freezing ele- V ments and drains into the trough 40 and from the trough 40 into the auxiliary makeup tank 46 and into the main tank 44. This operation is continued until the bond of the ice layer onto the surfaces 16 is released whereby the ice 7 sheet-falls gravitationally downwardly from the freezing plates 14 clear of thetanks 44' and 46.
  • the breaker is illustrated in the form of an elongate cylindrical member 74 mounted for rotational movement about a horizontal axis.
  • 'A plurality of rigid fingers 76 extend outwardly radially from spaced peripheral portions of the cylindrical member for a distance from'the breaker plates 78'which is less than the thickness ofjthe sheets of ice to effect breakdown of the sheets of ice as they pass therebetween.
  • the breaker plates comprise rigid metal anvil members fixed to extend crosswise to the lower end one side being more numerousthan the openings on the These same results can be accomplished merely by increasing thesize or capacity of openings on one side by 5 comparison with the openings on the other so that a cor-.
