    Abstract: A modified water drain pan for use in an ice maker is positioned below a vertically oriented evaporator and includes a front lip for receiving run off water from the evaporator during an ice making cycle. The lip includes a plurality of spaced apart ice removing structures defining a V-shaped groove there along. The V-shaped groove is defined by a plurality of front and rear angled surfaces. In operation, when the ice is harvested, the ice sheet falls from the evaporator such that a bottom edge thereof lands within the V-shaped groove. The bottom edge of the ice sheet contacts a front surface of the V-shaped groove wherein the force applied there against by the weight of the entire sheet causes the sheet to rotate about an imaginary axis extending within and along that groove. As a result thereof, the top of the ice sheet tips in a forward direction away from the evaporator where upon it falls into an ice bin there below.

    Abstract: An apparatus and method is provided for precipitating water ice or CO2 snow downwardly over a load within a shipping container or semitrailer body. The apparatus and method utilize high pressure and high velocity fog-like spray discharges of liquid CO2 and water (for forming water ice) or opposing high pressure and high velocity fog-like spray discharges of liquid CO2 (for forming CO2 snow) for intimate commingling in an elevated area of the container or semitrailer body. The commingling fog-like jet discharges of water and liquid CO2 cause water ice precipitation downward over a load within the container or semitrailer body and are capable of producing ice at a rate (poundage) equal to generally 96% of the rate (poundage) at which liquid CO2 is consumed in forming the water ice. Further, the opposing and commingling high pressure and high velocity fog-like spray discharges of liquid CO2 cause CO2 snow to form and to precipitate downward over an associated load.

    Abstract: The invention relates to a process and an apparatus for the granulation of granulatable and/or pelletizable substances in which the substance to be granulated is introduced in the form of a closed jet into a rapidly flowing refrigerant--preferably liquid nitrogen. This purpose is served by a vertically arranged reaction tube (2) into the upper part of which the jet enters and through which the refrigerant circulates by means of a transport element (7).

  • Patent number: 5653114
    Abstract: A method and system for electronically controlling the location of the formation of ice within a closed loop water circulating unit. A method and system is provided for making ice using supercooled water. When a desired degree of supercooling is reached in the closed loop water circulating unit, a pump associated with the ice-making machine is stopped so as to initiate ice seeding on the ice mold. After the pump is restarted, the supercooled water flows over the seeded molds to rapidly form ice on the ice molds. A method and system is also provided for improving the clarity of the ice. Water is preheated prior to introducing the water to the closed loop water circulating unit. Furthermore, in an ice-making machine having two or more ice molds, a method and system is provided for allowing one mold to act as a condenser in a harvest mode, while simultaneously allowing the remaining molds to act as evaporators in the freezing mode.

  • Patent number: 5582018
    Abstract: A method for preventing the formation of icy slush within the sump of an ice maker. The method includes the steps of monitoring the temperature of the water being circulated through the ice maker and detecting when the temperature reaches about 32.degree. F. When the water reaches about 32.degree. F., the water pump is turned-off to allow residual water on evaporator plates of the ice maker to freeze and form ice crystals thereon. The water pump is turned-off for a predetermined period of time sufficient to allow the residual water remaining on the evaporator plates to freeze, which is preferably about 40 seconds, before it is turned back on. Thereafter, circulating water gradually freezes to the ice crystals formed on the evaporator plates. This prevents the water in the sump from cooling below about 32.degree. F. which would cause an icy slush to form in the sump. The above cycle is repeated after ice is harvested from the evaporator plates.

  • Patent number: 5520011
    Abstract: A flow type ice making machine comprises at least one cooling zigzag pipe 14 or 15 through which a coolant flows, a pair of ice making plates 17 and 18 vertically disposed so as to sandwich the cooling zigzag pipe therebetween, and a pair of mount plates 11 and 12 vertically disposed at both ends of the ice making plates, respectively, and supporting opposite bent ends of the cooling zigzag pipe. The pair of mount plates have respective cut-out portions 11b and 12b being open upward, and a sprinkling device is inserted to the cut-out portions so as to cover upper ends of the ice making plates. A pair of extension fins 27a and 27b formed along opposite outer side surfaces of the sprinkling device, respectively, are sandwiched between the pair of mount plates to thereby position and fix the sprinkling device.

  • Patent number: 5402650
    Abstract: The disclosed thermal storage composition includes water, an electrolyte or a non-electrolyte, and a nucleating surfactant. The nucleating surfactant reduces the surface tension of the thermal storage composition and simultaneously promotes nucleation sites within the thermal storage composition. The thermal storage composition is directed along at least one heat exchanger surface cooled by a refrigerant. The thermal storage composition forms ice crystals that selectively accumulate on the heat exchanger surface. Forces resulting from gravity and the interactions with the liquid of the thermal storage composition overcome the adhesion forces between at least a portion of the ice crystals and the heat exchanger surface, causing at least a portion of the ice crystals to separate from the heat exchanger surface.
