08 January 2024, New Delhi: A team from NIT Rourkela has designed an innovative, cost-effective cooling chamber to address challenges in storing and transporting tomatoes. This mobile and zero-energy device operates on the principle of evaporative cooling, using a low-cost insulation layer to maintain produce at an optimal temperature of 16–18°C.
Developed at a cost of ₹1.4 lakh, the chamber can hold up to 750–1,000 kg of produce and is ideal for preserving perishable goods. Its mobility allows it to be mounted on various vehicles, including trucks, tractors, small pickups, and even trailers, offering flexibility for efficient transportation.
One of the standout features of this device is its energy efficiency, as it doesn’t require any external power supply. By utilizing wet pads to facilitate evaporative cooling, the chamber naturally reduces temperature and maintains the necessary humidity levels for fresh produce.
The unit is also available in portable versions, catering to small-scale users like vegetable sellers and distributors. Professor Madhuresh Dwivedi, a member of the project, highlighted its potential to revolutionize the transportation of perishables while providing an eco-friendly solution.
The team, which included several professors, researchers, and PhD scholars, presented their innovation at the “Tomato Grand Challenge” during the National Consumer Day event in New Delhi on December 24. Their work is expected to significantly benefit farmers and traders, ensuring better storage and reduced wastage of agricultural produce.
The Department of Consumer Affairs, Government of India, in collaboration with Innovation Cell, Ministry of Education had initiated a hackathon titled Tomato Grand Challenge (TGC) by inviting innovative ideas at various levels of the tomato value chain.
