Vegetable Powders (Onion, Ginger, Garlic)

Transforming raw vegetables into high-quality powders increases shelf life and market value.

• Peeling & Washing: Ensure produce is thoroughly cleaned and washed 2–3 times.
• Slicing: Slice the produce to a thickness of 2–3mm to ensure even drying.
• Drying & Processing: Use the hemispherical solar dryer for effective dehydration, followed by professional pulverizing, packing, and labeling.

Banana and Moringa Leaf Powder

Maximize the nutritional potential of bananas and moringa through solar dehydration.

• Banana Processing: After peeling and washing, slice into 2–3mm pieces and dry in the hemispherical solar dryer before pulverizing.
• Moringa Processing: Clean and wash the leaves thoroughly before placing them into the solar dryer.
• Final Steps: Once dried, proceed to pulverize the material into a fine powder, ensuring hygienic packing and labeling for final distribution.

Beetroot and Carrot Powder

Preserve the vibrant color and nutrients of root vegetables using our solar technology.

• Preparation: Peel and wash the beets and carrots thoroughly.
• Drying: Slice the vegetables to a 2–3mm thickness for optimal drying in the hemispherical solar dryer.
• System Overview: The process utilizes a comprehensive setup including a solar collector, biomass boiler, and heat exchanger to maintain consistent quality.

Innovation Beyond the Classroom

Our approach to sustainable development is built on real-world impact. We focus on technologies that matter, such as:

• Large Capacity Hemispherical Solar Dryers: A game-changer for preserving agricultural produce, ensuring hygiene, and extending shelf life.
• Renewable Energy Solutions: Developing efficient systems like solar cookers, wind mills, and water turbines to support off-grid needs.
• Agricultural Value Addition: Empowering users to transform raw crops into high-value products like powders, raisins, and herbal oils, following the quality-first “SOLVIVA” philosophy.

Solar Drying & Disinfection Systems

These systems are designed to improve food shelf life, ensure hygienic protection, and provide sustainable processing solutions.

• Large Capacity (1 Ton) Hemispherical Solar Dryer: This system is specifically developed for the rural ecosystem to promote resource efficiency and local value creation. It is equipped with a solar collector, biomass boiler, hot water tank, and heat exchanger to support $24\times7$ operations.
• Solar Dryer cum Disinfector (1 kg, 100 kg, & 500 kg capacities): These units provide effective disinfection from rain, dust, and contamination, extending the shelf life of food grains by up to 6 months. They also support the hygienic disinfection of clinical materials and hospital linens.

Rural Utility & Innovation Projects

These projects focus on practical, low-cost solutions for daily rural needs:

• Retrofitted Bicycle-Operated Pump: A mechanism consisting of a bicycle frame, piston-cylinder, and bearing system designed to act as a positive displacement water pump.
• Earthen Pot (Amey Pot): An innovative application of an earthen pot functioning as both a drinking water pot and a cold storage unit.
• Sustainable Ventilation System: An initiative focused on enhancing thermal comfort through the use of evaporative cooling.

Value-Added Processing Protocols (SOPs)

Using the Hemispherical Solar Dryer, various products can be processed following specific quality standards. The core mantra for all these processes is:

“Cleanliness, proper drying, and proper storage—this is the mantra of quality”.

Project/Product	Process Highlights
Vegetable/Fruit Powders	Involves peeling, washing (2-3 times), slicing (2-3mm), drying in the hemispherical solar dryer, followed by pulverizing and packing.
Raisins	Includes washing and pre-treatment (dipping in potassium carbonate and edible oil), drying (7-10 days), grading, and packing.
Ayurvedic Hair Oil	Involves cleaning/cutting medicinal plants, drying, and heating them in coconut oil using the solar dryer for 6–8 hours to extract properties, followed by cooling, straining, and bottling.
