Cross-Flow-Filtration
Cross
flow filtration involves mainly micro-porous hollow fibre membranes. The raw
vinegar is conducted at high speed diagonally to the membrane surface thus
preventing the spontaneous formation of a coating. The constant flow ensures a
clean surface of the membrane which is essential for a high, stable filtration
performance. In most cases the microfiltration modules used in vinegar
production are equipped with capillary membranes with a nominal pore size of
0,2 µm. This pore size guarantees the extraction of undesired constituents in
order to achieve a sterile product.
 Key benefits
- No
need of filter aids
- Only
one filtration step
- Compact
design
- Capillaries
of polysulfone with defined separation size
- Reliable,
fully automatic SIEMENS process control
The Filtration Plant
The
Cross-Flow Filtration systems range from small, manually operated plants with capacities
of 300 l/h up to fully automated large-scale plants with a capacity of 10.000
l/h.
Fully
automatic for 24hr operation with rinsing and cleaning intervals for high
capacity.
Semi
automatic with manual selection of the individual process steps (which then take
place automatically).
Manual for low filtration
volumes with unsupervised operation, but valves are operated manually.
