Dosing processes are technical methods used to fill products—liquid, viscous, or solid—into containers such as bottles, canisters, or jars in precisely defined quantities. They form the basis for accurate, safe, and cost-efficient filling in industrial production.
Selecting the right dosing method depends on product characteristics (e.g., viscosity, particulate content), the required fill volumes, and industry-specific hygiene standards. Modern filling lines therefore use a range of technologies.
Key dosing methods:
- Flow measurement (electromagnetic, Coriolis, ultrasonic) for highly accurate liquid filling
- Piston dosing for viscous products such as creams, pastes, or sauces
- Gravimetric dosing based on weight measurement
- Volumetric dosing using pistons or chambers
- Time-pressure dosing for simple, low-viscosity products
Benefits of modern dosing technology:
- High dosing accuracy and repeatability
- Flexibility when changing products and container formats
- Reduced product losses
- Hygienic cleaning options (CIP/SIP)
Typical applications:
- Food and beverage (oils, dairy products, juices, sauces)
- Chemical industry (cleaning agents, paints, lubricants)
- Pharmaceuticals and cosmetics (syrups, lotions, ointments)
Standards and quality requirements:
- CE marking in line with the Machinery Directive
- HACCP and GMP for food and pharmaceutical production
- ATEX versions for media in potentially explosive atmospheres
