- On Saturday (May 06, 2018) Dr. J.B. Joshi Sir visited Vigyan Ashram and the discussion on dryer design were happen.
- In this discussion the rough design were decided to work on.
- The points related to the dryer design were as following
- The box will be of 15 trays size
- The tray size will be 50cm × 50cm × 1 cm size
- The space between bottom to bottom of two trays will be 2.5cm
- There will be door from one side for loading and unloading of trays.
- 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.
- Initial model made in CATIA V5 R20 as follow

- 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 ;
- The design should be for 50cm × 50cm size trays only
- The trays should not be perforated
- Inlet and Outlets are missing
- To reduce the clearance between door and trays
