  2. The tray size will be 50cm × 50cm × 1 cm size
  3. The space between bottom to bottom of two trays will be 2.5cm
  4. There will be door from one side for loading and unloading of trays.
  5. Two sides will have the holes.

In this Dryer design, The CAD modelling work is assigned to me, Which I have to send it to Ameya Kulkarni for CFD analysis.

  • In this design after discussing with Dixit Sir I have taken the box dimensions for 40cm × 40cm size trays.
  • The trays designed were perforated.

After sending it to Ameya we got return mail stating that ;

  1. The design should be for 50cm × 50cm size trays only
  2. The trays should not be perforated
  3. Inlet and Outlets are missing
  4. To reduce the clearance between door and trays
