The ingredients should be processed with maximum efficiency and resource utilization to consistently offer high-quality and safe food, ensuring the greatest possible convenience for customers and consumers. Flowmeters are an important measuring instrument in process control. Due to the special conditions of production in viscous foods conventional measuring devices are often not suitable.
Such conditions are:
- High-viscosity of pastes
- Low flow rate due to larger nominal pipe diameters
- Varying viscosity when the process temperature changes
Possible consequences are:
- Inaccurate measured values when mixing the ingredients
- Incorrect level quantities in the storage and feed tanks
- Fluctuations in taste, consistency, or other product properties
- Fluctuations in product quality, due to measurement inaccuracy
- Product losses due to measurement inaccuracies
These requirements relate in particular, but not exclusively, to the following process steps:
- Mixing / dosing, with blending system
- Pasteurization (Excluding Grade “A” Pasteurization) / UHT / HTST (The highly viscous consistency of food poses a particular challenge here. The HTST pasteurization process requires a compliant protocol in many countries and therefore requires highly precise and reliable measurement).
