This spreadsheet is used to calculate mass
balance, heat balance and to design a Rotary
Dryer. Rotary Dryer is a long cylindrical
equipment that is used to dry a wet solid
material (powder) by contacting the material
directly with a hot gas. In this spreadsheet,
the material to be dried is wood powder
considering its chemical and termophysical
data are available enough in some
literatures. However, it does not mean that
this spreadsheet is only used for wood
materials. Other materials can also be
applied in conditions its required chemicals
and thermophysical data are available.
Anything else Spreadsheet Marketplace
should know about your spreadsheet?
The spreadsheet consists of 5 sheets, namely
sheet 'README', 'Data_Hf & Cp',
'NeracaMassa', 'NeracaPanas', and' DesainRD
'. Sheet 'README' contains information on
this spreadsheet and how to use it. Sheet
'Data_Hf & Cp' contains data Hf (Heat of
Formaton) and Cp (Heat Capacity) which are
used in sheet 'NeracaPanas'. Sheet
'NeracaMassa' contains data input and output
calculation (mass balance) of the Rotary
Dryer. Sheet 'NeracaPanas' contains the
calculation of enthalpy input and output of
the Rotary Dryer. And sheet 'DesainRD'
contains the calculation of design of the
Rotary Dryer such as Diameter, length and
electricity demands (bhp) of the Rotary
Dryer. All sheets are linked each other
except sheet 'README'.
