A heat exchanger has at least one inlet and outlet to permit circulation of refrigerant therethrough. Each heat exchanger includes a plurality of thin sections of material arranged between a pair of thin flat outer plates. Each of the thin sections of material is comprised of parallel flow paths, allowing for the refrigerant to flow through the inlet, then from one section to the next, and finally out the outlet. The arrangement of the sections of parallel flow paths allows for the refrigerant to come into contact with the majority of the inside wall of the outer plates, allowing for maximum heat exchange. In use for cooling liquids, the heat exchangers are arranged within a frame and brought into contact with the liquid to be cooled. When the heat exchangers are used to cool liquid sufficiently to produce ice crystals, a rotating scraping device sweeps across the surface of the heat exchanger, removing any ice crystals that have formed.

1. An apparatus for scraping material from first and second parallel plates, comprising: a) a shaft passing perpendicularly through the first and second plates;b) an inner carrier secured to the shaft and positioned perpendicular to the shaft parallel to the first and second plates;c) a hollow outer carrier positioned between the first and second plates and removably connected to the inner carrier so that the inner carrier is in sliding engagement within the hollow outer carrier;d) a plurality of scrapers positioned along the length of the hollow outer carrier; ande) means for keeping the scrapers in contact with the first and second plates. 2. The apparatus of claim 1, further comprising means for rotating the inner carrier in a plane parallel to the first and second plates. 3. The apparatus of claim 1, wherein the plurality of scrapers includes first and second sets of scrapers, each of the first and second sets of scrapers being maintained in contact with one of the first and second plates. 4. The apparatus of claim 1, wherein the inner carrier is secured to the shaft by a base plate. 5. The apparatus of claim 1, wherein the the inner carrier is removably connected to the hollow outer carrier by a removable bolt. 6. The apparatus of claim 3, wherein the scrapers are plastic. 7. The apparatus of claim 3, wherein the first and second sets of scrapers are maintained in contact with the first and second plates, respectively, by a rubber bumper, the outer carrier and the rubber bumper orienting the first and second sets of scrapers in a V-shaped configuration in relation to one another, wherein the first and second sets of scrapers buttress one another from opposite sides of the rubber bumper to maintain contact with the first and second plates, respectively. 8. The apparatus of claim 3, wherein each of the scrapers includes a first edge and a second edge, and wherein the scrapers are reversible to permit either the first edge or the second edge to be maintained in contact with one of the first and second plates. 9. An apparatus of claim 7, wherein the first and second plates are first and second adjacent plates, respectively, of first and second adjacent flat plate heat exchangers mounted on the shaft; wherein the first and second sets of scrapers are positioned along the length of the outer carrier; and wherein the rubber bumper maintains each of the first and second sets of scrapers in contact with one of the first and second adjacent plates. 10. An apparatus of claim 9, wherein each of the first and second flat plate heat exchangers comprises a refrigerant inlet, a refrigerant outlet, a first outer plate, a second outer plate, and an inner layer sealedly sandwiched between the first and second outer plates; wherein each of the first and second outer plates has an inner surface and an outer surface; wherein the inner layer at least in part defines a series of fluid channels through which a refrigerant flows; wherein each of the series of fluid channels is defined in part by the inner surface of one of the first and second outer plates and by the inner layer; and wherein the series of fluid channels provides a flow path between the refrigerant inlet and the refrigerant outlet. 11. The apparatus of claim 1, further comprising a plurality of nozzles operable for spraying a liquid on the first and second plates. 12. The apparatus of claim 1, wherein the inner carrier is secured to a first side of the shaft, the apparatus further comprising: a tube secured to a second side of the shaft opposite the first side; anda plurality of nozzles in the tube operable for spraying a liquid on the first and second adjacent plates. 13. The apparatus of claim 9, wherein the inner carrier is secured to a first side of the shaft, the apparatus further comprising: a tube secured to a second side of the shaft opposite the first side; anda plurality of nozzles in the tube operable for spraying a liquid on the first and second plates.
