Definitions

  • the present invention relates to cabinet apparatus for containing ice cream, sherbet and the like, for maintaining the contents at a desired temperature, and for ready access by servers, particularly in a commercial retail establishment.
  • Ice cream or ice-cream
  • Ice cream is a frozen dessert usually made from dairy products, such as milk and cream, which is often combined with fruits or other ingredients and flavorings.
  • the resulting mixture of chosen ingredients is stirred slowly while cooling, in order to incorporate air and to prevent large ice crystals from forming in the product.
  • the result is a smoothly textured semi-solid foam that is readily scooped.
  • the ice cream product is poured into tubs and frozen for delivery to commercial outlets for ice cream.
  • These outlets or stores usually have cabinets for containing the tubs, which maintain the temperature of the tubs in the proper range of about - 10°F to +10°F, and in which the tubs are positioned for access by servers.
  • Most ice cream tubs are cylindrical, although some have a rectangular or square cross section.
  • the tubs are placed in a cabinet either without any lateral restraint, or multiple tubs are sometimes banded together to keep them from turning or shifting.
  • it is necessary to replace an empty tub with a full one it is necessary to disband all tubs in the group, replace one tub and reband the group. This impairs efficient serving of customers.
  • the tubs are not easy for a server to replace during a time of high activity.
  • a server In present cabinets a server must reach deeper and deeper with a scoop to access the ice cream as the level of the product falls lower, which can make access to the bottom of the tub difficult, particularly for short persons. Additionally, it is difficult for persons to remove tubs, as one must bend far over to reach the bottom of a tub for removal. Further, the tubs are kept frozen by cooling coils in the vertical walls of the cabinet.
  • a server changing a tub occasionally scrapes against the accumulated ice crystals on the side of the cabinet, knocking bits of ice into the ice cream in the replacement tub, creating a contaminated food product, which is unappealing to the consumer.
  • the invention provides an ice cream dipping cabinet in which tubs of ice cream are provided with individual tub receptacles surrounded by cooling coils which are configured inside the cabinet around the ice-cream tubs.
  • the cabinet has a solid top plate which orients the individual tubs. This allows lower maintenance time and cost, helps keep moisture out and cold air in the enclosed bottom of the cabinet.
  • a top plate is provided that has holes for the tubs, which, when the tubs are in place, limits the escape of cold air from the cabinet, improving energy efficiency, as well as improving the overall visual aesthetics of the cabinet and the ice cream display, and the ease of access to the desired tub by the server.
  • the invention is an apparatus for cooling and storage of cold or frozen foods, comprising:
  • top plate engaging said box, and having one or more receiving holes therethrough;
  • a cooling coil assembly within the base, arranged about said at least a portion of each tub receptacle for cooling the tub and the contents thereof;
  • the principal object of the present invention is to provide a cabinet for storing and accessing frozen confections which has low energy consumption. Another object of the invention is to provide a cabinet for storing and accessing ice cream having improved and efficient time-motion capabilities. A further object of this invention is to provide an ice cream dipping cabinet that protects the quality of the ice cream stored therein. Another object of the invention is to provide an improved ice cream dipping cabinet having a readily accessible cooling coil for ease of maintenance and repair of a damaged coil. Another object of the invention is to provide an improved ice cream dipping cabinet having low and slow ice buildup which requires less defrosting than current cabinets. Another object of the invention is to provide an improved ice cream dipping cabinet having improved storage capacity over that of current cabinets. Another object of the invention is to provide an improved ice cream dipping cabinet having improved presentation of the product therein.
