Abstract

Claims (20)

1. A system for cooling chewing gum, the system comprising:

a chewing gum;

a cooling housing including a relatively upper cooling environment including an upper cooling chamber and a relatively lower cooling environment including a lower cooling chamber;

a conveying device configured to convey the chewing gum from an entry point to an exit point of said cooling housing, said conveying device at least partially delimiting said relatively upper cooling environment from said relatively lower cooling environment;

a first cooling system configured to provide cooling output to said upper cooling chamber of said relatively upper cooling environment using a first cooling fluid provided from a first cooling fluid source, said first cooling fluid being air and said first cooling system including a convective cooling system having at least one fan for moving said air across the chewing gum in a direction perpendicular to a flow of the chewing gum, wherein a face of said at least one fan is oriented parallel to said conveying device;

a plenum configured to direct a cyclical flow of said air cycling between said at least one fan and an evaporator

a second cooling system configured to provide cooling output to said lower cooling chamber of said relatively lower cooling environment using a second cooling fluid provided from a second cooling fluid source, said second cooling fluid source being different than said first cooling fluid source, second cooling fluid being a liquid, wherein said second cooling fluid source is at least one cooling jet positioned to spray said second cooling fluid to a lower surface of said conveying device,

a blocking device configured to fluidly separate said upper cooling environment and said lower cooling environment, wherein said blocking device comprises an enclosure surrounding said second cooling system;

said enclosure being defined at an upper portion by a stationary structure carrying said conveying device and by said conveying device itself, thereby allowing said at least one cooling jet direct access to said lower surface of said conveying device,

wherein said blocking device further comprises a gasket structure extending laterally from inner walls of said cooling housing to a portion of said conveying device.

2. The system of claim 1 , wherein said first cooling system is a convective cooling system and said second cooling system is a conductive cooling system.

3. The system of claim 1 , wherein said upper cooling environment has a pressure greater than atmospheric pressure.

4. The system of claim 1 , further comprising a dehumidifier fluidly connected to said upper cooling environment configured to lower a dew point below a temperature of said upper cooling environment.

5. The system of claim 1 , wherein a fluid from said first cooling system is directed to apply a compressive force to the chewing gum.

6. The system of claim 1 , including a gum alignment device arranged adjacent an edge of the chewing gum, wherein a configuration of the gum alignment device reduces any lifting force acting on the chewing gum by directing a fluid flow across the chewing gum.

7. The system of claim 1 , wherein the chewing gum is not conducive to turning or bending back upon itself due to the chewing gum being at least one of:

friable;

multitextural;

inclusive of a non-uniform surface texture; and

absent dusted compositions.
