1. Process Control Instrumentation for Food Technology An overview of the basic concepts of process control and its application in food technology - By Priyanka Bandyopadhyay M . Sc FST 3 rd SEM CA1 MSUFT-304

2. Process control is the use of various techniques to ensure that a process operates in a consistent and predictable manner. In food technology, process control is crucial for maintaining quality, safety, and efficiency in food production. It involves monitoring and adjusting process variables to achieve the desired outcome. Process control is essential for ensuring that food products meet regulatory standards and consumer expectations. Introduction to Process Control

3. Key Components of Process Control Measurement: Accurate measurement of process variables such as temperature, pressure, pH, and flow rate is essential for effective process control. Control: Control systems are used to monitor and adjust process variables to maintain optimal conditions. Feedback: Feedback loops provide information about the current state of the process and allow for adjustments to be made in real time. Automation: Automation plays a crucial role in process control by reducing human error and improving efficiency.

4. Product Quality: Process control ensures consistent quality by maintaining precise conditions during manufacturing. Food Safety: Process control measures help prevent contamination and ensure that food products are safe for consumption. Efficiency: Optimized process control leads to increased productivity and reduced waste in food production. Traceability: Process control allows for accurate record-keeping and traceability throughout the production process. Applications of Process Control in Food Technology

5. Challenges and Future Trends in Process Control Advanced Sensors: Development of more advanced sensors for accurate measurement and monitoring of process variables. Data Analytics: Utilizing big data and analytics to analyze process data and optimize control strategies. Automation and Robotics: Advancements in automation and robotics for improved process control and efficiency. Quality Management Systems: Integration of process control with quality management systems to ensure consistent product quality.

6. Types of Process Control Instrumentation Temperature control Pressure control Level control Flow control

7. Types of Control System Manual Control Automatic Control Automatic control system can be classified into four main types. On/Off (Two Position) Controllers Proportional Controllers ( P-Controller) Proportional Integral Controllers (PI-Controller) Proportional Integral Derivative Controllers (PID-Controller)

8. Function of Different Controller Manual control may be used in those applications where changes in the manipulated parameter cause the process to change slowly and by a small amount. Automatic Control – On/Off controller used in heating, air-conditioning, water heaters and oven. PID-controller used in chemical processing, power generation and manufacturing, decrease the average power supply to the heater. P-controller helps in response of closed loop system, becomes faster but maximum overshoot also increase. PI-controller used to decrease the steady state error without affecting the stability of the control system.
