Design and Automation of An Innovative Osmotic

This article presents the design and automation of an innovative osmotic dehydra-tor system that integrates a Programmable Logic Controller (PLC), a Human-Machine Interface (HMI), and an Internet of Things (IoT) sensor for precise con-trol of syrup concentration during the dehydration process. Unlike existing equipment, which often overlooks real-time monitoring and control of syrup con-centration—a critical factor affecting mass transfer and product quality—this de-sign emphasizes its continuous measurement and regulation to optimize process efficiency. The PLC serves as the central control unit, managing temperature, re-circulation, and other process parameters, while the HMI provides an intuitive platform for operators to monitor and adjust settings in real time. Although this article focuses solely on the design and integration stage, without experimental validation yet completed, it lays the groundwork for future testing and optimiza-tion. The proposed system represents a significant advancement in osmotic dehy-dration technology, promising improved control, product consistency, and opera-tional efficiency in food processing applications
