Pasteurisation Pressure & Temperature Control
Pasteurisation is the cornerstone of food and beverage safety — a precisely controlled heating process that eliminates harmful micro-organisms while preserving product quality. Whether you’re operating HTST (High Temperature Short Time) plate heat exchangers, tunnel pasteurisers, or batch systems for dairy, juice, beer, or ready meals, accurate and reliable pressure and temperature measurement is essential to ensure every cycle meets regulatory hold-time and hold-temperature requirements.
At Stork Solutions, we supply a comprehensive range of hygienic pressure transmitters, temperature sensors, electronic pressure switches, differential pressure transmitters, PID controllers, and digital pressure gauges — all purpose-built for food and beverage environments. Every instrument is designed around flush-diaphragm or welded-diaphragm construction, CIP/SIP compatibility, and the material standards demanded by modern food processing.
Product Spotlight for Pasteurisation Pressure & Temperature Control
Why Specialist Instrumentation Is Needed for Pasteurisation
Pasteurisation environments subject instruments to:
Repeated CIP/SIP cleaning cycles at temperatures up to 150 °C with aggressive caustic and acid agents
Rapid thermal cycling between ambient, pasteurisation (72–95 °C+), and cooling temperatures
Hygienic dead-space-free connections (Tri-Clamp, Varivent®, dairy pipe) to prevent product residue and bacterial harbourage
Regulatory traceability requiring SIL 2 functional safety, HART® communication, and IO-Link digital diagnostics
Low surface roughness diaphragms (≤ 0.4 µm Ra) for antibacterial cleaning and residue-free operation
Standard industrial transmitters lack the wetted-part materials, process connections, and cleaning resistance required. Purpose-designed hygienic instruments ensure compliance, measurement stability, and long service life.
Hygienic Flush-Diaphragm Pressure Transmitters
The core of any pasteurisation pressure monitoring system. Flush diaphragm designs eliminate dead space where product can accumulate, ensuring hygienic operation and accurate readings even with viscous dairy products, sauces, or fruit pulps.
