The Problem

 Cooling 60 gallons of

soup from 180F to 70F

 Put into containers (8 gal)

to cool to 140F

 Handling hot soup leads to

many burns

 According to health codes

have 2 hours to get to 70F

 Put in blast chiller  Uses forced air convection

to cool; energy intensive

SLIDE 3

Our Solution: Heat-pipe cooling

 Safe:

 prevent handling of soup

when hot

 Easy to implement:

 do the majority of the

cooling while in pot

 Pipes easy to remove

and clean

 Non-invasive

 The system minimizes

direct contact with soup

SLIDE 4

Technical Feasibility

 Using a lumped-parameter model; assumed:  properties of soup equivalent to water

 temperature of water to be 40F  heat transfer coefficient 340-450 W/m2K  low end area estimate

 Cooling time approximately 75-100 minutes
