摘要： An economizer arrangement for ice making reverse cycle refrigeration system of the type employing hot-gas defrosting, including a condenser, a receiver to receive liquid refrigerant, a plural tube evaporator having an internal refrigerant chamber in each tube and an expansion valve through which the refrigerant flows into the evaporator tubes during a freezing cycle of the system to cause ice formation on ice-making surfaces of the evaporator means in heat exchange relation with the refrigerant chamber. A rotary screw type compressor supplying to the condenser and has an economizer port at a location along the screw where the pressure builds up to a selected level, a refrigerant valve passes the condenser and routes hot-gas refrigerant during a harvest defrost cycle to the evaporator tubes, and a relief conduit tube communicates the refrigerant chambers of the evaporator tubes with the economizer port. The relief conduit having a relief regulator valve therein set to relieve the pressure being built up in the refrigerant chambers during the defrost cycle to a selected level to provide optimum pressure for ice harvest during defrost by controlling this pressure and transferring most on the refrigeration load of pulling the defrosted circuit back down to normal refrigeration temperatures to the economizer port of the screw compressor.

摘要： A novel apparatus for harvesting ice from an ice maker is disclosed. A refrigeration system having a hot gas bypass valve and a water cooled condenser is used to make ice. A programmable controller interrupts the water supply to the condenser, causing the condensing pressure to rise rapidly. This pressure increase is sensed by a pressure sensor, which then opens the hot-gas valve, sending hot gaseous refrigerant to the evaporator to harvest the ice.

摘要： An ice storage bin and discharge apparatus for discharge of uniform size ice to an outlet station for bagging or other use, including an ice bin in the form of an elongated insulated storage receptacle for containing a mass of ice, and endless floor level conveyor adjacent and overlying the bottom wall spanning the length and width thereof defining an upper flight for advancing the mass of ice toward a discharge end wall of the bin. A first drive is provided for driving the floor level endless conveyor at a predetermined speed, and an ice shearing mechanism is provided at the discharge end wall comprising a plurality of ice shaving blades positioned to lie in a vertical cutting path extending above and aligned with a transverse discharge conveyor with the shear blades collectively transversely spanning substantially the width of the bin at plural levels above the discharge conveyor. A second drives moves the shear blades at a constant predetermined speed substantially through the height of the bin across the face of the ice mass being advanced toward the discharge end wall by the floor level conveyor to shear a selected thickness of ice particles off of the face of the ice mass to fall into the working zone of the discharge conveyor.

摘要： A cube ice storage and dispensing bin in the form of a large stationary elongated insulated tank of generally cylindrical configuration having a large pool of water therein maintained substantially at water freezing temperature in liquid state. The tank has a pair of longitudinally extending screw conveyor flights, which may be of skeleton-like construction, arranged along axes paralleling the longitudinal center axis of the cylindrical tank and located to opposite sides of the center axis. The screw conveyor flights are journalled in the end walls and driven at a slow speed producing gentle agitation and and tumbling of ice cubes floating in the pool to disrupt tendencies of the ice cubes to form multicube frozen blocks of ice and maintain a slurry of ice cubes and water therein. Transverse conveyor screws are provided adjacent each end for transferring floating ice cubes from an end region of one of the pair of longitudinal flights to the other, and a discharge conveyor having a conveyor screw and a cage-like trough is provided at the discharge end to selectively withdraw ice cubes from the pool of water and discharge them externally of the tank.
