Treffer: Development of a Raspberry Pi-Based Automation System for an Induction-Heated Milk Pasteurizer.

Induction heating has recently gained prominence as a preferred technology in industrial, medical, and household systems, owing to its superior advantages over traditional heating methods. The key to devising an energy-efficient methodology for heat treatment of food raw materials using an induction heated pasteurization tank lies in the effectiveness of the process automation system. Addressing the automation issue pertaining to a pasteurization induction unit, the authors explore the capabilities of AVR and ARM microcontrollers. These are employed to establish a comprehensive development environment for managing, constructing, testing, and deploying an embedded microcontroller application. Utilizing the Thonny development environment, Python programming language version 3 is implemented to write and execute programs on the Raspberry Pi microcomputer. This microcomputer is wielded to regulate the operation of the pasteurizer prototype and its various associated peripherals, including sensors that measure diverse milk pasteurization parameters. Throughout the operation of the unit, all components maintain communication with the controller. The control panel facilitates the management of the installation and renders data output. As a result of this study, a control program and algorithm were developed for a prototype of an induction-type installation, empowering control and surveillance of milk pasteurization processes.
