The main Objective of the Project is to Control and Monitor the Pasteurization and Homogenization Process of Milk
In order to increase product quality and to minimize energy consumption and impact on the environment, it is necessary to optimize the food process design and operation. Therefore, the aim of this work was to study the optimization feasibility of the milk pasteurization process using programmable logic controller (PLC) & Supervisory Control and Data Acquisition System (SCADA)
Principle idea of this project is to show automation of milk pasteurization & homogenization using Allen Bradley RS Logix 500 software and Wonder ware Intouch 9.5 software.

Raw Milk Reception Dock (RMRD) is the primary point of liquid milk entry in dairies in India
The collection process starts from the villages, groups of which are assigned to distinct Milk Truck Routes
Here the milk is weighed and tested and also generates the receipt statement according to the measured parameters

Milk analyzers measure fat contents, solids nonfat (SNF), milk density, protein and added water.
Measured milks: cow, sheep, buffalo, and goat milk
Measuring time: 40 sec.
Measurements per hour: 65-70

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids.
A Process named after scientist Louis Pasteur which uses the application of heat to destroy human pathogens in foods.

High-pressure homogenizers are generally needed when high efficiency homogenization is required
Cream Distribution before and After Homogenizer
It is a stainless steel storage tank
Inside the storage tank thermocol are insulated like a sandwich
It wont allow outside temperature to inside & vice versa

Automation which is a set of technologies that results in the operation of industrial machines and systems with out significant
human intervention and achieve superior performance compare to manual operation
Self Diagnosis Less Time Low Errors Human Effort will be Low Higher productivity
Programmable Logic Controllers ( Industrially Hardened Micro Computers )Programmable Logic Controllers ( Industrially Hardened Micro Computers ) Ease of programming and reprogramming Immediate Documentation Rugged Construction & Modular Design Centrally available Diagnosis Moderate to Low initial investment cost

SCADA stands for Supervisory Control and Data Acquisition. As the name indicates, it is not a full control system, but rather focuses on the supervisory level. As such, it is a purely software package that is positioned on top of hardware to which it is interfaced, in general via Programmable Logic Controllers (PLCs), or other commercial hardware modules.
Features of SCADA: Dynamic process Graphic Alarm summery Alarm history Real time trend Historical time trend Security (Application Security) Data base connectivity

ConclusionConclusion The automation of Milk Processing in the Dairy Field is Controlled and Monitored the
Pasteurization and Homogenization Process of Milk by using PLC ( Allen Bradely ) and
SCADA ( Intouch ) Effectively
Conventional method of control and maintenance of Processing of Milk are now affectively
replaced with state of the Microprocessor based PLC System, which made the control and
maintenance easy, efficient and flexible.
