Abstract or Summary
  • Using returnable bottles within a brewery setting can lower costs associated with purchasing new bottles as well as reduce the energy associated with recycling glass bottles. A commercial dishwasher was retrofit specifically to wash bottles. The design and assembly of the piping flow network, testing of water flow through the network and testing of the cleanliness of the bottles post washing are presented in this study. This requires simultaneous analyses of mass and energy conservation equations. The flow out of the piping network was examined by running water through the network and collecting the exiting water in beakers for a specified period of time. These data were used to determine the exiting velocity and report the variations in nozzle mass flow rate. The measured exit velocity of water was found to vary from nozzle to nozzle by as much as 11%. All measured velocities were within 5.7% of those predicted from theory. The outer nozzles had a lower velocity than the nozzles closer to the water source. Although the velocity was different than the calculated values, the total mass exiting the piping network was equal to within ±0.25% of the calculated value. The bottles were swabbed to determine compliance with food safety standards. All cleaned bottles met food safety standards.
