Precise pressure measurement in homogenisers – Reliable measurement technology for demanding processes

Challenge: Extreme process conditions

In the food, pharmaceutical and cosmetics industries, homogenisers are used to process liquids, suspensions and slurries under high pressure into a stable, uniform mixture. The measuring points are often subject to extreme pressures, pulsating loads and high hygiene requirements.

During homogenisation, the product liquid is forced through narrow gaps or nozzles under high pressure. The resulting shear forces break down particles or fat globules and ensure uniform distribution. In dairies, for example, this process prevents the formation of a cream layer in milk and ensures consistent texture and flavour. In pharmaceutical and cosmetics production, this method is used to manufacture creams, lotions and suspensions with high stability. In biotechnology, the technique is used for cell lysis. 

These applications place high demands on measurement technology: in addition to precision, the instruments must be hygienically sound, easy to clean and durable – even with frequent CIP/SIP cleaning cycles and fluctuating process pressures.

Solution: DD8020 diaphragm seal – compact, robust, hygienic

The Labom DD8020 diaphragm seal is used for this demanding application. It combines a robust construction with a hygienic design and the highest measurement accuracy, in conjunction with state-of-the-art transducers.

Advantages at a glance

• Hygienic design in accordance with EHEDG
• Can be combined with all Labom transmitters or pressure gauges
• High measurement accuracy even in pulsating high-pressure processes
• Robust construction for a long service life
• Easy integration into existing systems
• Various connection sizes and clamping flange sizes available
• Resistant to frequent cleaning cycles (CIP/SIP)

The compact design and smooth, dead-space-free surfaces enable easy cleaning and prevent product build-up.

Practical experience and market potential

Leading manufacturers such as HST, GEA, Tetra Pak, SPX, Alfa Laval, Soavi and IKA-Werke use homogenisers on a large scale worldwide. Wherever homogenisers are in use, the DD8020 can demonstrate its strengths – particularly in milk processing, food production, pharmaceutical manufacturing and the cosmetics industry.

With its combination of precision, hygiene and robustness, the DD8020 is an ideal partner for operators who wish to ensure long-term process reliability and product quality.
