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.
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.
