Creating drying curves of UPL powder at different temperature using drying apparatus.
I took trial at 40 degree celcius, 60 degree celsius and 80 degree celcius. The drying curves are below,
I observed heater was not heating above 40 degrees and Current flow in drying apparatus was not good. The digital temperature and humidity sensors were working but there was problem to do wet bulb because of compact box size.
Create next prototype of drying apparatus.
