Raheja invented solar dryers that are very portable, foldable, and scalable. So, this solar dryer assists small and marginal farmers in enjoying better earnings from extra produce.

How Raheja Designed Engineer’s Solar Dryers Benefitted Farmers?

Before this year, when farmers in the region were trading tomatoes at a low price, Nitin Ramesh Dhingre from Maharashtra made a smart decision to convert fresh produce into dried products using a solar dryer.

As per the report collected by The Better India, the 38-year-old farmer explains that they were unable to even cover the cost of production when selling tomatoes for Rs 2.5 per kg, as they also had to cover the cost of harvesting and transportation to the market.

By considering this issue, Nitin started drying excess produce last December. He grows tomatoes, grapes, and onions on a five-acre land in his village Matur, and earns Rs 350/- for the same quantity he used to get Rs 50. Within five years he earned Rs 1 lakh as profit by selling excess produce. If not, that would have gone to waste.

Despite initial skepticism from other farmers, Nitin invested in a solar dryer which has now become popular among them. Nitin and 13 other farmers supported each other to install a three-tier solar dryer with the ability to dry up 500 kg of excess produce at once.

Varun Raheja has helped Nitin and other 50,000 farmers across India to acquire advantages from excess produce. That’s the reason, Varun and his mother Babita Raheja run Raheja Solar Food Processing Pvt Ltd and help farmers boost their sales and revenue without wasting food.

History Of Varun Raheja & His Invention

Varun is a mechanical graduate, who spent his 4-year college period studying farmer suicide rayes and methods to boost their earnings. He loves nature and hates wasting resources

“When I see a fruit coming out of a tree that is just dependent on soil and water, I perceive it as magic. Whenever I saw farmers throwing their produce, I would wonder about ways to preserve it so that they could sell it for a better price. I found solar dryers as a sustainable choice,” disclosed Varun.

Also, Varun has done an internship under Padma Shri Janak Palta McGilligan in his first year of college. Through that experience, he learned the benefits of solar power. At the end of his college life, he implemented the solar power technique in his solar dryer invention and supported farmers to use the waste in value-added products.

Also, Varun Raheja used all his mechanical knowledge to improvise solar dryers. Finally, he developed a foldable and portable solar dryer with different capacities that range from 20 to 100 kilos.
