Design and Testing of a Solar Powered Blancher cum Dryer Using IOT

Abstract

More than 30% of India's GDP is generated from horticulture. More than half of the food that is produced gets wasted because of its perishable nature, lack of proper equipment, procedures, and storage. The present preservation procedures include one of the classic techniques used to preserve things, namely research preservation. Preserving food using traditional techniques, such as drying is a common practice in agriculture. To dry fruits safely, temperatures should be between 45 and 60 degrees Celsius. Our concept is tiny and portable, as well as inexpensive to manufacture. In this system, we have forced local air to be blown to create more resistance to the rising air before the blower, which is installed below the coil and exhaust fan, which uses several different power sources to meet client demand (like solar, electricity, natural sources of fire etc). For drying, we utilise forced hot air (also known as hot air + forced hot air) followed by a blower with a capacity of 60W. To blanch, we employ local steam which is driven via copper tubes, which are immersed in a nosy solution and then sent through a blower. Alternatively, we can regulate the steam or provide it manually. To sterilise, we employ forced air blowers and UVC light sources. The duration the food is in the steriliser is programmable. The example includes a customizable hybrid system to meet the needs of the clients. To make the system more efficient, save cost and time of labour, the design can link all three operations into one single unit.
