Students from the Vidyavardhaka College of Engineering in Mysuru have designed a low-cost cooling cart for vegetable vendors that will keep perishable produce cool in the summer.
The makers of the cooling cart, Naveen HV, Shubham Sain, Supreeth S, Vivek Chandrashekhar, are third-year mechanical engineering students in college. They explained that the carts could even be used to store dairy products since the refrigeration of the cart could be maintained within a temperature range of 0 to 10 degrees Celsius.
Speaking of the innovation, Naveen, who led the research team, said: “Initially, we researched the problems faced by suppliers from all possible sources and wanted to find a workable and practical solution. We considered the experts’ suggestions and then came up with an air-cooled chamber and powered by solar energy for electricity to keep the machine self-sufficient. The current model requires sellers to charge it once a day at home, after which the system depends on solar power for its electricity needs. »
Talking about the team’s plans to improvise the cart further, Chandrashekhar said, “We plan to improvise more with pressure sensors that will help generate power from the pressure generated when the vendor sells the cart. We also plan to make the cart more energy efficient by transforming it into an electric two-wheeler in which more solar panels will be included and the storage capacity of the cart will be increased.
Speaking about his experience while working on the project, Supreeth said, “We have currently used smaller wheels for the cart which makes it a bit difficult for an individual to move it as it requires him to apply more force. . We would like to install 19 inch wheels which will make the trolley easier to pedal. We had to find a balance between our exams and the development of this trolley. It gave us a lot of learning about managing projects in difficult circumstances. We are extremely happy to have been able to do this successfully. We are happy to work on such projects if we have the opportunity.
Prof Sadashivegowda, Principal of Vidyavardhaka College of Engineering, said: “This is a good project from our students. There is always room for improvement and our students are there. They improvise the project based on the suggestions they receive. This project will help fruit and vegetable sellers, especially during hot summers. Vendors can deliver harvest to customers without losing its freshness. Not only during the summer, this cart can be useful throughout the year due to the tropical conditions of the country.
