Abstract: An arrangement for making, proportioning, discharging and storing small clear ice bodies includes at least one freezer unit for continuously producing small ice bodies from water. An insulated housing arranged undernearth the at least one freezer unit for the immediate storage of the small ice bodies includes means for revolving the small ice bodies and for conveying the small ice bodies to an outlet opening in the bottom of the housings. The intermediate storage housing has a bottom plate which is inclined toward the outlet opening. A pipe screw is provided for revolving and conveying the small ice bodies. A unit for proportioning and filling includes a filling chamber arranged underneath the outlet openings. A bag storage housing is arranged underneath the intermediate storage housing and includes at least one inlet opening which is positioned in the region of the proportioning and filling unit. The bag storage housing has at least one opening for removing the filled bags.

Abstract: An apparatus for producing small clear ice bodies includes an evaporator (110) having freezer cells (12) open at the bottom and cooled by a refrigerant pipe (11). Interspaces between the freezer cells (12) are covered by strips (114) of insulating material. On the outside of the insulating material (114) defrosting components are arranged, formed of metal strips (17). Water is sprayed upwardly out of a trough (30) into the freezer cells by means of a spraying device (20) in the form of a bucket wheel rotatable about a horizontal shaft (29). The bucket wheel has two spaced parallel circular discs (28) with concave splash blades (27) arranged between them. The water sprayed upwardly keeps the metal strips (17) at above-freezing temperatures, so that ice layers cannot form and interconnect the small ice bodies. Splash-guard walls (33), as well as a movable splash-guard flap (32), prevent the escape of water from the apparatus. When defrosted, small ice bodies (1) fall onto an inclined grid (36).

Abstract: A device for comminuting small ice bodies includes a housing without top and bottom walls in which a horizontally extending shaft is rotatably mounted. Disks forming beater knives are mounted on the shaft and counterknives in the form of cross-shaped breaking members are attached to the housing. Groups of adjacent disks define chambers in such a way that each chamber receives exactly one ice body. The chambers are arranged distributed over the circumference of the disks and along the length of the shaft in such a way that only a single ice body is comminuted at a given time. This reduces the power required for driving the shaft to a minimum.

Abstract: A method and apparatus for cooling a fluid coolant is disclosed. Cooling water, not under pressure, is circulated in a container. The coolant is passed under pressure through cooling pipes immersed in the cooling water.

Abstract: In a system for producing clear ice bodies by dipping freezing fingers into a tank of water and causing the water to move about the fingers as ice builds up thereon in order to remove air and salt from the ice bodies, the amount of water required per unit weight of ice obtained (since the water remaining from each batch is ordinarily discharged on removal of the frozen fingers containing the ice bodies) is decreased by maintaining the fingers stationary and producing the water movement by moving the tank so as to produce tank-wall to tank-wall waves. The top portions of the freezing fingers are covered by the water only during the crest of the waves.
