Field Case Studies

Measured impact, household by household

These field case studies document exactly what a Rudra solar dryer changed for real producers — from home kitchens in Nagaland and a women's self-help group in Himachal Pradesh, to a commercial farm-foods unit in Andhra Pradesh. Real produce, real capacity, real income.

Income generation Dimapur, Nagaland

Chillies and figs that finally earn a fair price

Mrs. AbeniHome food processor

Mrs. Abeni once dried her produce in the open, at the mercy of the weather. With a Rudra solar dryer, she now dries figs, lemons and red chillies in a clean, enclosed cabinet and grinds the chillies into a graded powder that buyers in Nagaland are happy to pay more for.

  • Figs
  • Lemons
  • Red chillies
  • Chilli powder
≈ 10 kg dried / month
₹10,000 monthly income
It is easier and safer, and I no longer second-guess the quality of what I sell.
Small-scale processing Dimapur, Nagaland

A small drying unit that runs without the waste

Mrs. AboliSmall-scale food processor

Mrs. Aboli dries everything from King Chilli and tea leaves to chicken and pork on a small scale. Her open-air setup lost produce to spoilage and rarely looked market-ready. The enclosed Rudra solar dryer gives her a hygienic space to dry both vegetarian and non-vegetarian products while holding their colour and quality.

  • King Chilli
  • Tea leaves
  • Chicken
  • Pork
5–6 kg dried / month
₹5,000 monthly income
Product loss simply is not a worry any more, and what comes out looks clean and presentable.
Traditional Naga foods Dimapur, Nagaland

Hygienic drying for North-East staples

Mrs. AsoleTraditional food processor

Across the North-East, staples like fish, King Chilli and bamboo shoots are still sun-dried in the open, which leaves taste and shelf life hostage to the weather. Mrs. Asole adopted a Rudra solar dryer in Nagaland to dry fish and chillies in a controlled, enclosed chamber that suits local food-processing habits.

  • Fish
  • King Chilli
  • Bamboo shoots
  • Leafy greens
≈ 20 kg fish + chilli / mo
₹4–5k monthly income
It is convenient, it looks good, and I am completely satisfied with the results.
Business growth Dimapur, Nagaland

Drying through the monsoon — and growing because of it

Mrs. TollyFood-processing entrepreneur

Mrs. Tolly sells a wide spread of dried foods — meat, fermented soybean, ginger, garlic, maize and wild fruits. Rain, flies and fungus once cost her produce every season and capped how far the business could grow. With a weather-resistant Rudra solar dryer, she now processes 20–30 kg a month, right through the rainy season.

  • Meat
  • Fermented soybean
  • Ginger
  • Garlic
  • Maize
  • Wild fruits
20–30 kg dried / month
₹20–25k monthly income
Before the dryer, drying was difficult and risky. Now I run the business confidently, even when it rains.
Value addition Dimapur, Nagaland

Adding value to forest and farm produce

Ms. Vezosulu RhakhoProducer & forager

Ms. Vezosulu gathers and dries an unusually wide basket of produce — turmeric, ginger, beetroot, gooseberry, wild apple and roselle. Uneven open drying once dulled both quality and price. Her Rudra solar dryer now delivers uniform, hygienic results that customers accept far more readily.

  • Turmeric
  • Ginger
  • Beetroot
  • Gooseberry
  • Wild apple
  • Roselle
≈ 20 kg dried / month
₹10–20k monthly sales
My products look more presentable and hygienic — it has added real value and confidence to my work.
Self-help group Kullu, Himachal Pradesh

Eight women, one cabinet dryer, premium apricot oil

Aagaj SHG (Jyothi)8-member self-help group

High in Gadherni village, the eight-member Aagaj self-help group processes apricot, pears and wild grasses. Wildlife and uneven drying kept holding them back — until a 20 kg cabinet solar dryer, installed with SELCO Foundation and the state rural livelihoods mission, changed the maths. They now run the whole chain themselves and sell apricot oil at a premium through their own outlet in Manali, Himachal Pradesh.

  • Apricot
  • Pears
  • Nettle grass
  • Lemon grass
  • Apricot oil
₹1,400 / L apricot oil price
20 kg cabinet dryer
We manage everything ourselves now — from collecting wild apricots to extracting and selling the oil.
Commercial scale Nandyal, Andhra Pradesh

Cutting the power bill on 900 kg a month

Medari PullaiahSri Siva Sakhambari Farm Foods

At Sri Siva Sakhambari Farm Foods, Medari Pullaiah dries tomatoes, raw bananas, maize and lemons at commercial scale in Andhra Pradesh. Electric dryers were burning through power and still struggled with fungus. The Rudra solar dryer dries faster at lower temperatures, curbs fungus naturally with sunlight, and has trimmed the electricity bill on roughly 30 kg a day.

  • Tomatoes
  • Raw bananas
  • Maize
  • Lemons
  • Green-gram sprouts
≈ 30 kg dried / day
≈ 900 kg dried / month
Low-temperature solar drying is faster, it controls fungus, and it saves a real amount on power.

Switching from open sun-drying gave me cleaner, more consistent material to work with.
