Abstract:
The drying of materials is an important unit
operation in a manufacturing process. It is achieved
through application of various drying units. This project
was initiated to collect technical data on a drying unit
designated as ''Continuous Tray Dryer (CTD)".
For this study, a continuous tray dryer along with
hot air system was designed - and fabricated in the G.s.Div.
of PCSIR Labs. Complex, Lahore. The same was installed,
commissioned and successfully operated in R.I.Div. The
unit was subjected to one month operation during which
its performance was satisfacory.
Various materials can be dried on the unit but wheat
was selected for conducting operational test. The drying
paramete? such as Temperature, Moisture, Air ,distribution,
Residence Time were studied. The drying rate curves were
drawn which established the suitability of CTD unit for
drying purposes.
