牛奶加工混料过程中的PLC控制

The Milk Compounding Process Based on PLC

本文主要针对牛奶加工过程中的配料环节,采用PLC结合液位传感器和辅料精准计量装置严格按照配方执行,保证牛奶的品质和口味。该系统由传感器及变送器、PLC控制系统、人机界面就地显示仪表、气动开关阀等设备组成,实现计量、控制和管理的高度统一,有效地解决了以往人工操作时劳动强度大、且存在较大的计量误差,产品合格率不高且不稳定的问题。

This article mainly aims at the compounding process of milk manufacture.It combining PLC with ingredients link,and accessories level sensor precision measurement device executed strictly according to the formula,to guarantee the quality and taste.This system consists of sensors and transmitter,PLC control system,man-machine interface in situ display instrument,to realize measurement,control and management of the high unification,effectively solves the artificially operation labor intensity,larger measurement error and unstable problem.Compared with the traditional control scheme,it has advantages such as,simple operation,easy maintenance,high control precision,low equipment failure rate,greatly reducing the human misuse,fully meeting the requirements of the production process.
