The raising device 104 comprises a means to lift the grid 101 out of the freezing reservoir 103. Moreover, the raising device 104 may put the grid 104 in a position where the ice can be extracted from the ice cans 102. For example, a forklift, a hoist 205, a winch, or a motorized engine may form a raising mechanism may be used to lift the grid 101. In the one embodiment, the raising device 104 is a bar that provides a grasping point for the raising mechanism 201. In one embodiment, a raising mechanism 201 is absent altogether. Is such a situation, an individual may remove the grid 101 or one or more ice cans 102 through conventional manual extraction, such as manual lifting.

The lever 104 may comprises a horizontal piece 104a, a vertical piece 104b, and an eyehook 104c.
In the preferred embodiment, the horizontal piece 104a may be perpendicular to the vertical piece 104b and overlapping the edge of the freezing reservoir 103. The lever horizontal piece 104a may be connected to the grid 101. In one embodiment, the horizontal piece 104a may be shaped like a flat bar; however, an alternative embodiment it may also be shaped like a cylinder. In one embodiment, the vertical piece 104b may be arranged perpendicularly to the horizontal piece 104a and parallel to the walls 103a of the freezing reservoir 103. The vertical piece 104b may be connected with the horizontal piece 104a and the eye hook 104 can used in connect with the overall lever 104 to the raising mechanism 201 in order to lower and raise the grid into place. In one embodiment, the lever piece 104 may be flat; however, in an alternative embodiment it may also be round.

The can apertures 202 are holes in the grid 101 that house one or more ice can 102. Spatially, apertures 202 are alternative positioned between the inter-can spacing 217, which is the distance between the can apertures 202. The can apertures 202 function to both 1) form a frame for the ice can 102 to attach; and, to 2) hold the cans when raising and lowering into the brine freezing reservoir 103. In one embodiment, the can apertures 202 are primarily square-shaped; however, in other embodiments the can apertures 202 may also be round or rectangular. Further, the can apertures 202 are positioned to accept one or more freezing reservoirs 203.
The freezing reservoir 103 comprises a means for storing water to be frozen in a particular shape. In one embodiment, the freezing reservoir 103 may be positioned inside the can apertures 202 and immersed in the brine solution. The freezing reservoir 103 forms a mold that creates a block of ice that matches one or more industry standard for an ice making machine. The freezing reservoir 103 also interacts with the brine solution by transferring heat between the water to be frozen and the low temperature brine freezing reservoir 103. Further, in one embodiment the freezing reservoir 103 is an ice can 102.
The ice can 102 may comprise low grade stainless steel; but in other embodiments, may be created from any of the following: polyethylene, polybutylene, aluminum, copper, metal, silver, gold, or platinum. In one embodiment, the ice can 102 maybe square-shaped; however, in alternative embodiments the ice can 102 may be circular or rectangular in shape.
The freezing reservoir 103 is comprised of an insulated reservoir designed to store a brine solution that is chilled to temperatures well-below the freezing point of water. Moreover, the bath 2 functions to exchange heat between the freezing reservoir and the brine solution. The freezing reservoir 103 provides an improved heat-exchange system compared to air freezing; and promotes vertical expansion of water as it solidifies during the ice formation process. In some embodiments, the freezing reservoir 103 may be missing. In this case, heat exchange would not produce a proper ice formation. In one embodiment, the freezing reservoir 103 preferably comprises a holding tank for chilling a brine solution, and further comprises walls 103a, the re-circulator 111, the enclosing seal, and the coil cooling system 110.
The brine solution comprises a liquid solution used to promote lowering the freezing point of water and produce ice. In one embodiment, the brine solution 8 is situated within the walls of the freezing reservoir 103. The brine solution 1) cools the water in the ice can 102 to form ice blocks; and, 2) promotes even freezing of the ice blocks among the multiple ice can 102. The brine solution interacts with one or more ice cans 102 by surrounding and promoting heat-exchange (i.e., cooling) the water within them. In some embodiments, examples of a brine solution may include a salt solution, an ionic solution, a propylene glycol solution, a liquid nitrogen solution or the like.
Walls 103a of the freezing reservoir 103 comprises supporting physical elements forming the container of the freezing reservoir 103. Spatially, the walls 103a of the freezing reservoir 103 surround the brine solution and support the grid 101. In one embodiment of the invention, the walls 103a are generally thought to be created from the insulating material, but in other embodiments may be created of non-insulating material. The walls 103a preferably comprise an insulating material 103b, and a surrounding coating 103c, respectively.
Insulation 103b within the walls 103a reduces heat transfer for the brine solution and the outside temperature. Spatially, the insulation 103b may be positioned underneath the coating 103c and is the supporting material for, or within one or more wall 103a. The purpose of the insulation 103b is to reduce heat exchange between the external environment and the internal environment of the freezing reservoir 103. Further, the insulation aims to reduce condensation in and on freezing reservoir 103. In the main embodiment of the invention, the insulation 103b is may be foam. However, in some embodiments, examples of insulation 103b may include cork, plywood, insulating foam, an insulating paint or the like.
A coating 103c is a structure on the outside of the walls 103a comprising any liquid, liquefiable, or mastic composition that, after application to a substrate in a thin layer, converts to a solid or film coating. Spatially, the coating 103c may be positioned surrounding the insulation 103b and covering the walls 103a. The coating 130c functions 1) provide a non-conductive barrier between the brine solution and the insulation 103b; and 2) provide a non-conductive barrier between the exterior environment and the insulation 103b. In one embodiment, the coating 103c may comprise: enamel, paint, rubber, fiberglass, a resin, a gel coat or the like.
A recirculating pump comprises a means to circulate a solution in one or more circulation patterns within the freezing reservoir 103. Spatially, the recirculating pump may be positioned within the freezing reservoir 1032, and even more particularly at the center bottom of the freezing reservoir 103. The recirculating pump interacts with brine solution 8 by moving the solution through its interior components. In some embodiments, a recirculating pump may include a distiller or the like.
A coil cooling system 110 comprises a means of heat exchange, wherein transfer of cooling gas through coils 110 within the brine solution promotes heat transfer. Generally, it is thought that this system is composed of coils; however, in alternative embodiments, a non-coil system may be used to decrease the temperature of the brine solution. In one embodiment, the coils 110 are arranged in between the interior components of the ice cans 102 within and throughout the brine solution. The coils 110 comprise copper; however, alternative other embodiments may comprise the following materials: steel, stainless steel, or aluminum. In some embodiments, if the coils 110 are missing, other means for cooling the brine solution may be used. In one embodiment of the invention, the coils 110 are primarily shaped like a compressed spring, but in alternative embodiments may be shaped like a corkscrew, a spring, or any type of repeating s-pattern. In some embodiments, the coils 110 may be flat and in the shape of a sine wave so that they can be fitted in between the ice blocks for more rapid cooling. In this embodiment there may be rows of these coils arranged as boundaries between various blocks of ice.
An enclosing seal comprises a means to seal the freezing reservoir 103 from the external environment. In one embodiment, the enclosing seal is positioned above the freezing reservoir 103 and is used when the grid 103 is not in position (for storage). The enclosing seal prevents moisture from entering the freezing reservoir 103 and diluting the brine solution, while also preventing heat exchange between the brine freezing reservoir 103 and the external environment. In some embodiments, an enclosing seal 701 may include: a lid, a cover, a cap or the like. If the enclosing seal is missing, the system may be deployed without an enclosing seal.
A manifold 105 comprises a means to simultaneously fill the ice cans 102. In one embodiment, the manifold 105 may be situated on top of the grid 101. The manifold 105 allows rapid filling of the ice cans 102 with water. This precludes manual filling of the ice cans 102 and increases the speed of ice can 102 filling. The manifold 105 may comprise copper; however, the manifold 105 may alternatively comprise: steel, stainless steel, or aluminum. In one embodiment of the invention, the manifold 105 is preferably shaped like an ‘S’; however, it is thought that in alternative embodiments that it could be any shape that allows filling of the cans.
A lever 104 comprises a supporting or weight transfer system used to help orient the grid 102 when being lifted in order to remove ice from the ice can 102. In one embodiment, the lever 104 is positioned above the grid 103. The lever 104 is attached to and interacts with the hoist 205. In some embodiments, if the lever 104 is missing, other means for distributing the weight of the grid 103 for movement may be used.
