Single and double sided ventless humidity cabinet

Abstract

A ventless humidity cabinet system with entry window includes operating elements for providing an evenly heated humid air supply to products, such as food products, and utilizes any combination of air curtain fans, water tanks, inlet water lines, water inlet valves, wet heating elements, dry heating elements, water temperature probes, air temperature probes, air humidity probes, water level sensors, lower drain valves and a control computer.

What is claimed:  
     
         1 . A ventless environmental system comprising: 
 a cabinet housing having an entry window;    an air curtain output adjacent said entry window for moving air generally parallel to said entry window;    a first source of vaporizing moisture within said cabinet housing;    at least one sensor for measuring at least one of humidity and temperature within said and housing;    a first source of dry heat within said cabinet housing, said air curtain for moving air within said cabinet housing to expose said air to both said first source of vaporizing moisture and said first source of dry heat; and    a controller for controlling at least one of said first source of dry heat, said first source of vaporizing moisture, and said air curtain output in response to said at least one sensor.    
     
     
         2 . The ventless environmental system as recited in  claim 1  and further comprising a plurality of said at least one sensors within said housing, located at least two heights within said housing.  
     
     
         3 . The ventless environmental system as recited in  claim 1  and wherein said first source of vaporizing moisture within said cabinet housing further comprises: 
 a water containment structure within said housing; and  
 a source of heat directed to heat water contained within said water containment structure.  
 
     
     
         4 . The ventless environmental system as recited in  claim 3  and further comprising a source of fill controlled by a fill valve and a source of drainage controlled by a drainage valve, both said fill valve and said drainage valve controllably connected to and controlled by said controller.  
     
     
         5 . The ventless environmental system as recited in  claim 1  wherein said air curtain output is also for creating air flow inside said housing for circulation and mixing of the first source of vaporizing moisture and first source of dry heat within said cabinet housing.  
     
     
         6 . A ventless environmental system comprising: 
 a cabinet housing having a first access opening and a second access opening;    a first air curtain output associated with said first access opening and a second air curtain output associated with said second access opening for moving air generally parallel to its associated said first and said second access openings;    a first source of vaporizing moisture within said cabinet housing;    at least one sensor for measuring at least one of humidity and temperature within said and housing;    a first source of dry heat within said cabinet housing, said air curtain for moving air within said cabinet housing to expose said air to both said first source of vaporizing moisture and said first source of dry heat; and    a controller for controlling at least one of said first source of dry heat, said first source of vaporizing moisture, and said air curtain output in response to said at least one sensor.    
     
     
         7 . The ventless environmental system as recited in  claim 6  and further comprising a plurality of said at least one sensors within said housing, located at least two heights within said housing.  
     
     
         8 . The ventless environmental system as recited in  claim 6  and wherein said first source of vaporizing moisture within said cabinet housing further comprises: 
 a water containment structure within said housing; and  
 a source of heat directed to heat water contained within said water containment structure.  
 
     
     
         9 . The ventless environmental system as recited in  claim 8  and further comprising a source of fill controlled by a fill valve and a source of drainage controlled by a drainage valve, both said fill valve and said drainage valve controllably connected to and controlled by said controller.  
     
     
         10 . The ventless environmental system as recited in  claim 6  wherein said air curtain output is also for creating air flow inside said housing for circulation and mixing of the first source of vaporizing moisture and first source of dry heat within said cabinet housing.  
     
     
         11 . The ventless environmental system as recited in  claim 6  wherein said first and second access openings are openable and closeable entry windows located on opposite sides of said housing.  
     
     
         12 . The ventless environmental system as recited in  claim 6  and further comprising a divider wall at least partially dividing said housing into a first portion associated with said first access opening and a second access opening.  
     
     
         13 . The ventless environmental system as recited in  claim 12  and further comprising a plurality of said at least one sensors within said housing, located along said divider wall within said housing and enabled to measure conditions in both said first and said second portions.  
     
     
         14 . The ventless environmental system as recited in  claim 12  and wherein said divider wall includes a plurality of strategically placed apertures to enable selected communication between said first and said second portions.
