摘要
Abstract
This study addresses challenges in dairy industry pasteurization equipment,including low utilization rates,high energy consumption,and cumbersome product switching caused by dedicated machine configurations.A multi-variety flexible production system based on Programmable Logic Controller(PLC)and PID algorithms was designed.The hardware upgrade features four heat recovery tubes(K1)and a three-way proportional valve(CV565),forming an enhanced heat recovery circuit.The software system employs Siemens S7-300 series PLC with analog input module 331-7KF02-0AB0 and output module 332-5HD01-0AB0 as the control core.Real-time data collection through temperature sensors(TT605,TT607)enables dynamic PID algorithm adjustment of valve openings,achieving precise control over outlet temperatures(95℃,43℃,20℃).Successfully implemented in charcoal-baked yogurt(95℃)and other pasteurized dairy products,the system maintains stable outlet temperatures within±0.5℃of set values during operation.By integrating automatic control theory with heat recovery technology,this study achieves flexible and intelligent upgrades for pasteurization equipment,providing technical pathways and practical examples for digital transformation in traditional food processing machinery—a model with broad applicability.关键词
