Description
Summary:Solar drying of agricultural products is one of the key components in food handling and processing. Over the years critical evaluation of different dryer designs has been explored. However, this review paper presents the status of smart solar dryers (SSD). The article is largely focusing on key transition stages in the solar drying technology. Advancement and functionalism of dryer automation systems have been given a particular attention in this paper. Electronic controllers and sensors adopted in previous (2016 to 2022) dryer designs have been highlighted. The paper presents a brief overview of the commonly applied dryer kinetics and models. Economic attributes of smart solar dryers have been discussed in this review. There has been tremendous improvement in the level of intelligence being applied in SSD. PID controllers are the most used electronic control systems in SSD. The application of Internet of Things (IoT) through Arduino is now gaining wide recognition in emerging drying technologies. Aspects of thin layer modelling are extensively applied in the designing and operation of smart solar dryers. Life cycle cost and life benefit cost are figures of merit widely considered in measuring economic viability of any drying technology.
