Thesolution basicmodelwasdefined asaLow
Pressure Isothermal Evaporationprocess, of warm
dishes (directly from the dishwasher) in anadiabatic
control volume.
By lowering the pressure wecanachieve faster&
easier waterdroplets evaporation from the dishes
surface.
Introduction
Today'sexisting solutions fordishes
drying process at restaurant arenot
satisfactory; themost common
method is static drying in anambient
environment, a long and inefficient
process. Due to that, operational
bottle neck occurred, resulting in
unnecessary loss of resources such
as time&money.
An actual customer
feedbacksurvey of
about 10 restaurants
wasconducted at
multiple food
preparation
configurations, in
order todetermine
the project’scritical
requirements:
1. Drying quality
2. Fluent costs
3.Accessibility

MainObjectives
Aversatile solution is required, which canbeeffectiveondishes withvariable
geometry (such aswine glasses). in addition, asacomplementarypolishing effect
need toexamined, asanpossible integrated feature.
