Introduction
Process control equipment plays a vital role in modern food manufacturing plants, ensuring that critical variables are continuously monitored, managed, and adjusted to maintain consistent product quality, food safety, and production efficiency. These systems include sensors, actuators, and transducers that gather data and interact with programmable control systems in real-time.
As a leading food industry consultant, PMG Engineering integrates state-of-the-art control systems into food factories to meet GMP, HACCP, and FSSC standards.
Objective
The implementation of process control equipment aims to:
- Reduce energy consumption
- Enhance manufacturing efficiency
- Ensure SOP compliance
- Lower pneumatic valve air usage
- Maintain consistent product output
These improvements align with the goals of food processing consultants and food factory project managers who strive to build smarter and sustainable operations.
Types of Sensors in Food Industry Applications
Sanitary Sensor:
Hygienic Adapter Systems (Fluid-less Type)
Uses corrosion-resistant duplex stainless steel and requires no silicon oil.
Digital Remote Sensors (DRS)
Measures differential pressure with high precision.
Diaphragm Seal Systems
Ensures safe pressure readings in sensitive environments.
Distributed Temperature Sensor
Monitors temperature distribution up to 50 km.
Ideal for fire detection, preventive maintenance, and equipment protection.
Tunable Diode Laser Spectrometers (TDLS)
Enables real-time gas analysis under extreme conditions.
Non-contact and process-isolated, ideal for food-grade environments.
Sushi Sensor
Enables real-time gas analysis under extreme conditions.
Non-contact and process-isolated, ideal for food-grade environments.
Level sensor:
Controls liquid levels, acid/alkali inputs, and gas flow.
Critical for ingredient dosing and process consistency.
Coriolis Mass Flowmeters
Recognized for highest accuracy in flow measurement.
Used in batching, dosing, blending, precision coatings, and more.
Actuators in Food Processing and Packaging
Types of Actuators
Electric Actuators
- Widely used in conveyor systems, packaging robotics, and bread robots.
- Benefits: hygienic, corrosion-resistant, fluid-free.
Pneumatic Actuators
- Powered by compressed air for fast, clean, and reliable motion.
- Suitable for material handling, palletizing, and automated systems.
Key Benefits
- Fluid-free operation
- Speed and efficiency
- Hygienic and robust design
- Cost-effective maintenance
As part of food technology consulting, actuator selection is crucial for both high throughput and regulatory compliance.
Piezoelectric Transducer
Converts mechanical stress into electrical signals.
Used for monitoring pressure, strain, and temperature in food systems.
Magnetostrictive Transducer
Produces high-frequency vibrations for ultrasonic cleaning and machining.
Valuable in precision food processing equipment.
Conclusion
Process control equipment forms the backbone of modern food factory automation. From sensors and actuators to advanced laser spectrometers and flow meters, each element plays a critical role in delivering safe, consistent, and efficient food products. PMG Engineering, as a trusted food processing consultant and engineering design partner, offers expert integration of these systems in world-class food manufacturing facilities.
