Sanitation system for refrigerated fixture having an air curtain

Abstract

A sanitation system for a refrigerated fixture having an air curtain. This sanitation includes a spray manifold positioned in a case tank of the refrigerated fixture. A reservoir is provided which is adapted to contain disinfectant. A pump is provided to pump disinfectant from the reservoir through the spray manifold, whereby disinfectant is sprayed into the case tank. A controller is connected to the pump and adapted to control the frequency and duration of the spray through the spray manifold.

       10 . In Combination: 
 a refrigerated fixture having a case tank and a product support supported by the case tank; a sanitation system for the refrigerated fixture, comprising:    a disinfecting spray manifold positioned in the case tank of the refrigerated fixture below the product support, the disinfecting spray manifold being arranged to provide thorough spray coverage in a swirling non-flushing spray pattern within the case tank without spraying product concurrently on display on the product support;    a reservoir adapted to contain a chemical disinfectant that kills bacteria on contact;    a pump adapted to pump disinfectant from the reservoir through the disinfecting spray manifold, whereby disinfectant is sprayed into the case tank;    a controller connected to the pump and adapted to control the frequency and duration of the spray through the disinfecting spray manifold.    
   
   
       11 . The sanitation system as defined in  claim 10 , wherein the disinfectant is a quaternary ammonium.  
   
   
       12 . The sanitation system as defined in  claim 10 , wherein water is supplied to the pump via a water supply line and a metering valve is used to combine desired proportions of water and disinfectant.  
   
   
       13 . The sanitation system as defined in  claim 12 , wherein a filter is provided on the water supply line to filter out contaminants.  
   
   
       14 . The sanitation system as defined in  claim 10 , wherein a one way valve is positioned on the water supply line to prevent backflow.  
   
   
       15 . The sanitation system as defined in  claim 10 , wherein a one way valve is disposed between the reservoir and the pump to prevent backflow.  
   
   
       16 . The sanitation system as defined in  claim 10 , wherein the pump and the controller are positioned on a panel.  
   
   
       17 . The sanitation system as defined in  claim 10 , wherein a flow regulator is used to maintain a constant flow rate.  
   
   
       18 . The sanitation system as defined in  claim 10 , wherein a metering valve is used to ensure a consistent injection of disinfectant.
