Definitions

  • the present invention relates to ice-making apparatus, and more particularly to apparatus useful in making efficiently ice in sheet form.
  • Ice-making apparatus of the type which the present invention is concerned includes many different alternative designs which may be characterized according to basic lconstruction as being plate i-ce, cylindrical ice and tubular ice apparatus, each of these apparatuses utilizing freezing elements of suitable geometrical design upon which the ice is frozen.
  • the present invention relates more particularly to, a plate ice machine which is capable of producing ice in given quantities more efficiently and at less cost than ⁇ prior apparatuses. Also, the present invention is. ⁇ directed toward the provision of apparatus which is simpler in design, economical in operation, and utilizes fewer moving parts.
  • FIG. 1 is a simplified side view of one embodiment of this invention
  • FIG. 2 is -a sectional illustration taken substantially 5 along section line 2--2 of FIG. 1;
  • FIG. 3 is a perspective illustration of the freezing element used in the preceding figures.
  • FIG. 4 is a perspective illustration of a baffle plate illustrated in section in FIG. 2.
  • the apparatus comprises a friame,rgenerally indicated by the reference numeral 10, formed of suitable angle iron to support the various pieces of the apparatus in proper position with respect to each other.
  • a friame generally indicated by the reference numeral 10
  • On this frame are mounted, by two suitable frame uprights 12, a pair of identical ⁇ freezing plates 114, these plates being parallel and vertically aligned as shown.
  • the outer surfaces 16 of these respective plates 14 are flat and vertical and .are in thermally conductive contact with pipes or passages 18 which carry and circulate the cooling refrigerant through the plates i4.
  • these plates or elements 14 are constructed of metal.
  • a distributor pan 22 Supported on the frame 10 ⁇ immediately above the de'ector plates 2G is a distributor pan 22 having upstanding sides and a bottom 24. ri ⁇ his pan preferably is of shallow construction and in length is coextensive with the horizontal dimension of the deector plates.
  • a series of horizontally spaced drain holes 26 In the bottom 24 are provided a series of horizontally spaced drain holes 26 in registry with the two ydeector plates 2i?, there being an adequate number of holes for producing a relatively even flow of water from the pan 22 over the entire exposed surface of the two plates 20 and also the freezing surfaces 16 of the plates 114. In a working embodiment of this invention, these holes may have a diameter of one-quarter (1/4) inch.
  • a distributor pipe 28 which extends horizontally and parallel to the plates.
  • This pipe is provided with a series of jet apertures 30 along the length thereof between the horizontal extremities of the plates 20, there being two axially aligned series of these apertures 30, one series being directed toward theleft-hand deflector 20 and the other series being directed toward the right-hand dellector 20 as viewed in FIG. 2.
  • Means is provided for connecting the left-hand end (fFIG. l) of this pipe 28 to a suitable source of'ambient temperature water, this temperature in -a working embodiment of this invention usually lying in the range of from 50 to 75 Fahrenheit.
  • the righthand end 32 of this pipe 28 is closed. Water introduced into the left-hand end of the pipe flows out of the jet ⁇ apertures and onto the respective deflector plates 20 and downwardly over .the back sides 34 of the freezing plates. 14.
  • a trough 44 Supported on the frame 10 immediately beneath the lower extremities of ⁇ the drain plates 38 is a trough 44) ⁇ .having upstanding sides :and a flat bottom. As viewed in FIG. 1, the right-hand end ofthe trough is closed while vthe left-hand end 42 is open. The trough is inclined slightly so yas to ydrain liquid-toward Ithe left as viewed in FIG. 1, the left-hand end of the trough extending slightly beyond the left-hand edges of the ltwoplates 318i and the freezing elements 14.
  • a water-collecting assembly which includes ⁇ a main tank 44 and an auxiliary tank 46. Both of these tanks 44 and 46 have flat bottoms and upstanding sides, the tank 46- being smaller rthan the tank 44 and supported inside the latter in an elevated positionby means of a suitable frame piece 48 ⁇ and, for example, an overflow pipe 50.
  • the tank 44 is made relatively deep so 'that when itis lled with water, any slush (ice) in the water will float near 'the top, leaving slushfree water adjacent the bottom thereof.
  • the tank 46 is positioned immediately beneath the discharge end 42 of the 'trough 40 so as to receive all of the contents which flow from the trough 40.
  • the bottom 52 of the tank 46 is provided with a series of relatively small apertures 54 through which water may drain into the larger tank 44.
  • the overllow pipe 50 stands upright and passes through the bottoms of both tanks 44 and 46.
  • the upper end S6 of the pipe 50 is disposed adjacent but below the upper edges of both tanks Overllow water spilling into Vthe tank 46 flows out of the overflow pipe 50 before it has la chance 'to pass into the larger tank 44 through the openings 54. This tends to prevent warm overow water from becoming mixed with water in the tank 44.
  • the bottom 58 of the tank 44 is 1an outlet 6U having a connection to a water pump 63l which pumps the Water from the tank 44 upwardly -into the distributor pan 22 as diagramrn'atically illustrated in FIG. 2.
  • a flat baffle plate 62 (see FIG. 4) having corners 64 bent downwardly to provide legs. The plate 62 and fthe bottom 58 thereby cooperate to draw water from the lower lateral portions of Athe tank 44 instead of drawing surface water downwardly directly into the outlet 6i). 'Ihe importance lof this feature will be explained more fully hereinafter.
  • the pan 44 is initially filled with water to a suitable level.
  • the refrigerating system (not shown) is started in operation to cool the plates 14 to a temperature below that at which water freezes.
  • the water pump 62 is energized, forcing water from the tank 44 upwardly :and -into the distributor pan 22. This water flows downwardly through the drain holes 26 onto the dellector plates 20, and from these plates it ows downwardly over the entire freezing surfaces 16 of the two freezing elements 14. Because of surface adhesion, the water will adhere to the surfaces 16 and will llow inwardly Aalong the drain plates I3S to drain into the trou@ 40.
  • the water drains into the auxiliary make-up tank 46, and from this tank it flows through the drain apertures 54 'and into the main tank 44 before repeating its ow cycle.
  • the freezing elements 14 cool down, 'the water flowing over the surfaces 16 will start -to freeze; however, this freezing action is not instantaneous but instead takes place relatively gradually and thus forms an ice-slush which does not adhere to the surfaces but instead flows downwardly into the trough 40.
  • This slush interferes with the proper operation of the apparatus, for one thing serving to clog the water pump 63 and the drain apertures 26 in the distributor pan 22.
  • the trough 40 is disposed at only a slight angle so that it is very nearly horizontal. This being true, slush tends to collect along the bottom of the trough. Any slush which ows out of the discharge end 42 of the trough next falls into the auxiliary make-up tank 46. Since the slush lloats in water, the slush will tend to remain iin the top of the tank 46 while only water drains through fthe apertures '54. The water which is collected by the tank 44 is rtherefore relatively free from slush. However, if some slush should pass through the apertures 54, it will oat to the top of the water in the tank 44.
  • This Water cycle is continued for a sufficient period of time until a lilm of ice builds to a suitable thicknesss on the freezing elements 14. Following this, the ice is harvested; this is accomplished by first stopping the refrigerating system and the circulating pump 63 and thereafter warming lthe plates 14 so as to release the ice sheets therefrom. This warming of the plates is accomplished by means of the llow of water over the back sides 34 from the distributor pipe 28, water at ordinary, ambient temperatures being used for this purpose. Of course, it is necessary that this water be at temperatures above freezing. The water llows downwardly over the back sides 34 of the freezing elements 14, drains into the trough 40, the auxiliary make-up tank 46 and into the main tank 44. This action is continued until the ice bond is melted sufficiently for the sheet to drop off the respective surface 16.
