A solar dryer is a sealed, insulated chamber that captures the sun's heat to raise air temperature and pull moisture out of food. Unlike open-sun drying, the produce never touches dust, rain or pests, so the dried output meets the hygiene standards that buyers and exporters demand.

We manufacture cabinet dryers from 5 kg to 50 kg batch capacity, plus large tunnel dryers for commercial throughput. Every unit is built from food-grade trays, UV-stable glazing and powder-coated steel, and is designed to run for years in harsh rural conditions with near-zero operating cost.

Most fruits and vegetables dry in 1 to 3 days of good sunlight, compared to 5 to 7 days in open-sun drying. Exact time depends on the crop, slice thickness and ambient conditions.

A solar dryer continues to work on overcast days at a slower rate. For year-round commercial drying we offer optional electric or biomass backup heating so production never stops.

Choose capacity by fresh-load weight per batch: 5 to 10 kg suits SHGs and home enterprises, 25 to 50 kg suits FPOs and small processors, and tunnel dryers suit large-scale operations.

Verified client reviews

  • 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.

    Rameshbhai Patel Director, Shree Khedut FPO · Gujarat

  • Hygienic, dust-free drying changed how buyers see our spice lots. Rejections dropped and we finally hit export-grade moisture levels consistently, batch after batch.

    Anita Deshmukh Spice Exporter · Nashik, Maharashtra

  • The community solar cooker feeds 200 children every afternoon at our hostel. Zero gas bills, and the meal is ready on time — rain or shine.

    Sister Mary Joseph Warden, St. Anne’s Institution · Karnataka

  • Rudra sized a 50 kg dryer exactly to our mango-pulp volumes. Their engineers commissioned it on site and trained our women’s group themselves — nothing was left to guesswork.

    Lakshmi Reddy Self-Help Group Lead · Krishna District, Andhra Pradesh

  • In Ladakh the cold and the altitude defeat most equipment. Their dryer kept working right through the season and our apricots now grade as premium.

    Tashi Norbu Citizen Foundation · Ladakh

  • The solar baking oven cut our bakery’s fuel cost dramatically. The even-bake quality genuinely surprised us — a better crust than the LPG oven it replaced.

    Imran Sheikh Bakery Owner · Hyderabad, Telangana

  • We deployed Rudra dryers across six SHG clusters. Their after-sales support is genuinely responsive — a call gets answered, not ignored.

    Priya Nair Programme Manager, Rural Livelihoods · Kerala

  • Clean drinking water from their solar still has been a quiet game-changer for our remote field station. Low maintenance and no running cost at all.

    Dr. Sanjay Verma Field Researcher · Rajasthan

  • Honest sizing advice. They told us a smaller unit would do the job rather than overselling — that earned our trust, and our repeat orders.

    Mahesh Gowda Food Processing Unit · Mysuru, Karnataka

  • From enquiry to installation in under three weeks. The 25 kg dryer runs daily for our amla and ginger-candy line without a hitch.

    Sunita Bhosale Women’s Producer Group · Satara, Maharashtra
