Cooling process after UHT orange juice destination optimization based on CFD

More Information
  • Received Date: March 06, 2012
  • Cooling process after the juice thermal sterilization.By now, there has not been the exact cooling process.Excess cooling is the usual style to obtain the qualified juice.After the heat-resistant temperature of the juice package was analyzed, and based on this, orange juice cooling numerical experiment after UHT sterilization numerical experiment was carried out using FLUENT software.The optimization cooling process was obtained: (20℃ (293K) , 9s) , (15℃ (288K) , 8s) , (10℃ (283K) , 8s) , (5℃ (278K) , 7s) and (0℃ (273K) , 7s) .Using Carnot efficiency in Reverse Carnot cycle, the energy consumption in different cooling process was calculated, and the optimized process was:20℃ (293K) , 9s.
