The above graph shows weight loss pattern of Azola. The trial was subjested to following conditions:
- T3 = 70 deg celcius
- F1(max) = 1.2 m3/min
- Substrate: Azola
- Initial Weight=56.376
- Final Weight=2.733
- Initial Water Content=54.233
- Target weight=2.142

Inspired from Pinterest I have designed and fabricated this mobile stand. This is to understand relation and form and function. I have made this using VA’s Plasma.
It is very crude. I am trying to go for new materials and design.
For fitting the Arduino controller and data logger on the control pannel.
The mount is bolt fitted on the control pannel.
Ther was a failure in Drum reinforcement due to buckling stresses induced.
1) Overloading of drum may be one reason.
The drum is designed for taking 20 Kg of garbage daily. Since the drum was overloaded the reinforcement failed and a metal strip was broken.
2) Bad fabrication method is another probable cause.
The reinforcement strips were not rolled but forced and screwed. The stresses due to this also led to the cracking and failure of reinforcement.
For this the reinforcement need to be redesigned and strengthened. The images show new fabricated reinforcement.
Today was I conducted trial on new heater for drying apparatus.
The heating section has 2, 150 mm length X Dia. 60 mm wrapped around a GI pipe and steel wool stuffed inside.
The heater is controlled using TC513 Digital temperature controller. Which helps in setting desired temperature for trial.
And yes we tried it. Dehydrating lemons..!!
LOD shows that lemons consist 94% of bound water.
We tried trials on different dryers. We loaded sample batches in Ambient temperature dryer, Solar Convection dryer and Direct sun drying. We compared the quality of product to justify the advantage of Ambient temperature dryer (Dome dryer).
Following image show the comparison.
In this trial we concluded by generating high retention of colour and flavour in Dome Dryer.
I helped in designing the AeroSense’s casing. Heres are some pics
Parts are away for 3D Printing
