JUICE BLENDING/BATCHING SYSTEM

The food manufacturing industry is always ripe for integration of major
improvements in process control and intelligent processing. At this time, even
though many new devices and systems are available for implementation in food
processing industry, the majority of the routine processing steps are still controlled
and performed by workers.
The report is on the design and implementation of the logic control functions on a
single-product batch process. The aim is to utilize the digital Programmable Logic
Controller (PLC) module to control the sequences in a batching process that
produces fruit juices hence, making the system fully automated by creating the
appropriate ladder diagram or program. Another aim of this project is to control and
drive the control valve opening and closing from 0% to 100%. This project also
demonstrates the advantages of using PLC in a plant.
The batching system is restricted to only four kinds of materials as the based of this
case study. The illustrated batching system also includes 5 valves, one agitator
motor, one pump and a batching tank. The end product of the batching system
should be commercial product of fruit juices.
The OMRON PLC is being used for programming, in order to create a ladder
diagram or program for the process of this project using the CX-Programmer
Version 3.0 ladder diagram language. The PLC device type is the SYSMAC
CQM1H-CPU21 with the network type of SYSMAC way.
