    • A machine for manufacturing ice including a plurality of elongated vertical tubes of uniform internal cross-sectional dimensions, a cylindrical shell for each tube of length less than the tube and surrounding a substantial portion of the length of the tube, the internal nominal diameter of the shell being greater than the maximum external cross-section dimensions of the tube, the shell having a spiral groove formed in the cylindrical wall thereof, the depth of the groove being such that the interior surface of the shell at the groove contacts at least part of the exterior surface of the tube thereby forming a flow path in the annular area between the exterior of the tube and the interior of the shell which is, at least in part, spiraled. Refrigerant gas is expanded in the tube-shell annular areas to chill the tubes. Water is introduced into the upper end of the tubes to flow downwardly through them and form in each tube a rod of ice. The tubes are then heated, such as by introducing hot gas into the annular tube-shell area to release the rods of ice which falls downwardly out the lower end of the tubes, the annular refrigerant flow path providing improved effectiveness and efficiency in chilling the tube for the formation of ice. Pivotally actuated cutter sever the rods of ice into short lengths. A diverter arrangements directs water flowing out of the tubes as ice is being formed into a reservoir and shifts to direct the produced ice out of the machine.
    • 一种用于制造冰的机器,其包括具有均匀内部横截面尺寸的多个细长垂直管,每个管的长度小于管并围绕管长度的大部分的圆柱形外壳, 壳体大于管的最大外截面尺寸,壳体具有形成在其圆柱形壁中的螺旋槽,凹槽的深度使得凹槽的壳体的内表面接触至少部分 从而在管的外部和至少部分地螺旋的壳的内部之间的环形区域中形成流动路径。 制冷剂气体在管壳环形区域中膨胀,以冷却管子。 水被引入管的上端以向下流过它们,并在每个管中形成一根冰。 然后将管加热,例如通过将热气体引入到环形管壳区域中以释放从管子下端向下落下的冰杆,环形制冷剂流动路径提供冷却管的改进的效率和效率 为了形成冰。 枢轴驱动的切割器将冰棒切割成短的长度。 分流器装置指示当冰被形成储存器时流出管的水移动并将产生的冰引导出机器。

    • An ice making refrigeration system embodying an accumulator tank above and externally of a refrigerant chamber and communicating therewith by valved means for gravity flow of liquid refrigerant to the refrigerant chamber during a freezing phase. The upper portion of the accumulator tank communicates with the intake of a compressor to deliver vaporized refrigerant thereto. The upper portion of the refrigerant chamber communicates with the accumulator tank by a vapor-liquid return conduit. The discharge side of the compressor communicates with a condenser and the liquid side of the condenser communicates with the vapor-liquid return conduit downstream of the refrigerant chamber and delivers makeup liquid thereto in the general direction of flow of refrigerant therethrough. Valved means delivers hot gaseous refrigerant under pressure from the compressor to the refrigerant chamber during a harvesting phase.
    • 一种制冰制冷系统,其在制冷剂室的上方和外部具有蓄液箱,并通过阀装置连通,用于在冷冻阶段使液体制冷剂重力流入制冷剂室。 蓄能器罐的上部与压缩机的入口连通以将蒸发的制冷剂输送到其上。 制冷剂室的上部通过蒸汽 - 液体返回导管与储液箱连通。 压缩机的排出侧与冷凝器连通,冷凝器的液体侧与制冷剂室下游的气液返回管连通,并在制冷剂的大致流动方向上向其供给补给液。 阀门装置在收获阶段将压缩机内的热气态制冷剂从压缩机送入制冷剂室。
