Hygienische Prozesse

Innovation and speed of development determine the production processes in the cosmetics, beverage, food and luxury food industries – as well as in biotechnology and pharmaceuticals. The manufacturing conditions in these future-oriented industries are among the most sensitive of all.

Industries & Topics Hygienische Prozesse

A comprehensive range of measuring technology for hygienic systems and processes

Innovation and rapid development characterise the production processes in the cosmetics, beverages, food, biotechnology and pharmaceutical industries. The production processes in these industries are particularly  demanding. Specific product properties need to comply with special hygienic requirements. The products are manufactured in highly complex and sometimes sterile processes.
  
Measuring and control components in machines and production facilities must therefore meet the highest standards. Sterile process separation, hygienic design of devices, superior quality of materials and maximum measuring accuracy are some of the key factors for maximum process reliability.

Discover new possibilities for your applications. With AFRISO.

Specific production processes

AFRISO components and system solutions are adapted to suit specific production processes and comply with the pertinent hygienic regulations and recommendations to meet stringent requirements. Our robust measuring devices deliver perfect measuring results and reliably monitor and control simple to highly complex processes. Sophisticated kit systems and innovative ideas such as the seal-free design of diaphragm seals, pressure transmitters and thermometers help in the continuous optimisation of production facilities.

Requirements for sterile processes

Manufacturing and processing food, cosmetics and pharmaceuticals involve highly demanding production technologies. 

A vast array of standards and stringent directives cover all aspects of the hygienic design of machines, systems and, of course, peripheral equipment such as measuring instruments. AFRISO products consider these standards. National and international approvals and certificates ensure superior quality.

(Pressure Equipment Directive) Pressure Equipment Directive 97/23/EG

Non-profit organisation (USA) for product safety in processes of the food and pharmaceutical industries.

Organisation of the US Department of Health. Issues recommendations, directives and test methods for the examination of materials.

Measuring technology for hygienic processes

Hygienic production equipment is designed in such a way as to avoid external contamination and microbiological pollution and to ensure easy cleaning. All wetted parts, i. e. materials coming into contact with the medium, must have been tested and classified as hygienic. The materials used in hygienic AFRISO measuring systems meet FDA requirements for contact with food and drugs as per CFR (Code of Federal Regulations), part 21.

These materials comprise metals as well as elastomers for seals or oils for transmission in diaphragm seals. The EHEDG recommendations are considered in the design of hygienic measuring instruments. AFRISO has been an EHEDG member since 2010; various process connections are EHEDG-certified (EL - Class I).

Precision turning/polishing assure a surface quality of the wetted parts with a medium roughness of Ra ≤ 0.8 μm. Please enquire for an even higher quality of up to Ra ≤ 0.4 μm.

The cleanability of components in closed systems is ensured by CIP (cleaning in place) or SIP (sterilisation in place) cleaning methods. CIP with circulation or flushing methods involve flushing a plant or parts of a plant with alkaline or acid cleaning agents and alcoholic disinfection agents and then rinsing with ultra-pure water. SIP uses hot steam to kill micro-organisms for sterilisation.

Diaphragm seal for hygenic separation of measuring instrument and medium

Chemical seals are mechanical process separators. They use a diaphragm to separate the medium to be measured from the measuring system. This separating diaphragm is joined to the body of the chemical seal, in hygienic applications usually by means of welding.

Diaphragm seal for hygenic separation of measuring instrument and medium

Chemical seal systems     

A chemical seal system consists of two connected devices (instrument and seal). Welding or screwing turn the chemical seal and the instrument (e. g. Bourdon tube pressure gauge, pressure transducer or pressure switch) into a single, inseparable unit. Spaces in the measuring element and channel holes are evacuated and then filled with a hydraulic transmission fluid. This transmission fluid transmits the process pressure to the instrument. The instrument and the medium to be measured are protected this way: The instrument cannot come into contact with hot, polluted or corrosive media and the medium is not polluted by corrosion or bacteria.
