Creating new collector design
To collect more heat without wasting
Cabinet design
Preventing the access of animals such as flies, rodents, strayed dogs and weather
Carrier wheel
Easy to carry and move for away
Best Air flow pattern
To dry raw materials quickly
Modification and Advancement of Traditional Technology
is utilized to dry substances
higher than the ambient temperature
extraction of humidity from crops inside a drying chamber

Our Activity
Survey the required at the local farm
Analyse the performance with seasonal vegetables & fruit
Knowledge sharing about our system with local cultivators

Day 2
Results & Impact
The performance of the dryer was evaluated using chili in which the initial moisture content was reduced from 80% to around 6% (equilibrium moisture content).
The collector efficiency was 47.41 & drying efficiency was 57.2
It was found that the solar dryer can dry high initial moisture content fruits such as pineapple and mango to the recommend value of moisture content for safe storage within 2 to 3 days.
Higher standard of hygiene
Significant time and energy savings
More revenue for local agriculturists
This technology is not only one of the best ways for tropical zones, especially Myanmar but also more economical and efficient compared to traditional open-air drying.
Collaboration with Local Agriculturists
Modifying traditional drying method by combing theory concepts, knowledge, idea and methodology learning from school made our quality of life better and better.
Quality
Instead of applying chemicals preserve, young learners should be educated to select modernized eco-friendly and users friendly.
Modernized
In studying advance technologies to use natural resources should be emphasized
