Development and Performance Evaluation of IoT based Dryer for Selected Food Materials

Abstract

Drying is one of the oldest methods of food preservation, but still the control newlineon the process parameters such as temperature, relative humidity and velocity of newlinedrying air result in high cost of processing. With the development of information newlinetechnology, the Internet of Things (IoT) allows for the collection and sharing of data. newlineIt can be used for a variety of purposes, such as monitoring and controlling equipment newlineremotely, automating processes, and collecting data for analysis. newlineLeafy vegetables are an important part of a healthy diet because they are newlinenutrient-dense and low in calories and also rich in vitamins, minerals, and newlineantioxidants. Two different methods were used to dry coriander and mint leaves such newlineas IoT based heat pump drying (IoT-BD) and heat pump drying (HPD). The drying air newlinetemperature for IoT based and heat pump dryers were 40, 50, 60 and 70°C and newlinerelative humidity of 10, 20, 30 and 40 per cent. After drying, the best sample, dried newlineunder optimal conditions, was chosen.contd..... newline
