Abstract: An evaporator includes a refrigerant conduit sandwiched between front and rear plates. The front plate has inner flat portions, each of which is spaced from a respective inner flat portion of the rear plate to define a respective spaced portion. The front and rear plates further include a set of first protrusions and a set of second protrusions. Each first protrusion on the front plate faces a respective first protrusion on the rear plate to define a respective active cavity. Each second protrusion on the front plate faces a respective second protrusion on the rear plate to define a respective passive cavity. The refrigerant conduit extends through each of the active cavities but does not extend through any of the passive cavities. The location of the active and passive cavities are interspersed and separated by respective inner flat portions so as to define a plurality of ice forming sites.

Abstract: Embodiments of the invention relate to systems and methods for providing a removable sliding access door for an ice storage bin. In one embodiment, an access door is provided for use with a storage bin. The access door can include protrusions that engage corresponding recesses on tracks located adjacent to an access opening of the storage bin. The sliding access door can permit a user to access or view the contents of storage bin, and can be easily removed from the storage bin without the use of tools.

Abstract: Embodiments of the invention include methods and apparatus to reduce or prevent bridging in an ice storage bin. In one embodiment, a storage bin for ice with an apparatus to reduce or prevent bridging within the ice storage bin is provided. The apparatus can include a probe hole positioned above an access door and opening, and also above an internal baffle. The probe hole can be sized to receive a probe used to break up bridges or clumps of ice within the ice storage bin.
