| dc.description.abstract | A solar powered portable cold storage was modified and developed for the storage of fruits and vegetables to increase their shelf-life. It was generally designed and developed in order to reduce post-harvest losses and ensure better returns for small and marginal farmer. The developed solar powered cold-storage is cost effective, simple and energy efficient unit. The installation, operation and maintenance cost of the cold-storage were also less in comparison with the existing storage facilities. It comprised of a solar AC, solar panels, compressor, cold storage structure, water tank, portable trolley, honeycomb pads and sensors. The cold storage structure was made up of Nova pan which were mounted on aluminium frame with sliding doors, the dimension of cold store was (2.431.982.43 meter) with the capacity of around 1.5-2.0 tonnes. The cold storage was fitted over movable trolley which makes it portable. The water tank was made up of an MS sheet of 1.21×2.43 meter size. The cold-storage was integrated with temperature and humidity sensor operated by the raspberry pi for remote monitoring of data. It was tested for its performance during early winter season. The minimum and maximum drop in temperature ranged between 12.5 C and 15°C, the increase in relative humidity was observed between 85% to 95% inside the cold-storage in the month of November. It was observed that there was considerable effect on physiological loss in firmness of different vegetables kept outside the portable cold-storage. The freshness and shelf-life of vegetables was increased substantially after storage in the portable cold-storage. The total cost of designed 1.5-2.0 tonnes capacity cold storage was around Rs.1,53,500/- including installation charges. | en_US |
