The electricity cut problem occurs much time so I decided to use solar energy in the daytime. A solar panel added to dryer and electricity will be used as a backup in daytime.


The batch started on 11th JAN’19. The procedure followed as follows;

  1. I had taken 3.5 kg sawdust.
  2. Then I had mixed 11-liter water in sawdust.
  3. Then the mixture kept as it is for half an hour.
  4. After that, I did the weight of it.
  5. I took 10 gm sample for LOD.
  6. Then I evenly distributed wet sawdust on each plate. As follows, Plate One- 1 kg, Plate Two- 1.5 kg, Plate Three- 2 kg, Plate Four- 2.4 kg, Plate Five-2.6 kg, Plate Six- 2.6 kg.
  7. Noted down the time when the batch was loaded.
  8. I took samples from the south and north side of each plate. After every six hour from the batch loaded in daytime.

The solar panel added. But the drying rate reduced. It took more time to dry.

Next Plan:

Minimize drying time and maintain temperature and humidity for better drying.
