We dry turmeric and chilli for 400 member farmers now without ever watching the sky. The tunnel dryer paid for itself in one season, and the colour we retain has lifted our market price.

FAQ
Working with Rudra Solar — questions answered
Rudra Solar Energy solar dryers and solar cookers are used by individual users, farmers, women entrepreneurs, SHGs, FPOs, food processors, MSMEs, NGOs, institutions, community kitchens and commercial processing businesses across India.
For solar drying, Rudra serves users working with suitable fruits, vegetables, spices, herbs, grains, pulses, oilseeds, seeds and other agricultural or food-processing products. Requirements can range from small household or farm-level batches to larger FPO and commercial processing applications.
For solar cooking, Rudra systems can support suitable household, community and institutional cooking requirements based on the selected model and capacity.
Rudra’s customer base includes real field users across different regions and applications, helping demonstrate how solar drying and solar cooking systems can be adopted at different scales.
Yes. Rudra Solar Energy documents measurable results from selected real solar dryer installations through its Success Stories and field case studies. Reported outcomes from individual projects include faster drying compared with open-sun methods, reduced post-harvest losses, improved processing consistency, lower dependence on conventional energy and increased capacity for value-added food processing.
For example, documented Rudra projects include cases reporting up to 30% reduction in post-harvest loss, 2–3× faster drying compared with open sun, and more than 75% improvement in drying time in selected applications. Commercial users have also documented regular batch processing at larger volumes.
Results are application-specific and depend on the crop or product, initial moisture, preparation, loading, weather conditions, dryer capacity and operating method, so these figures should be treated as field examples rather than guaranteed results for every customer.
