Product group description filtration units

Machines for separating a liquid into permeate and retentate using filter elements.

Filtration process

By pumping the liquid around over the filter under a specific (transmembrane) pressure, there is a specific flow of (flux) of the finer substances to the permeate. The coarser elements in the liquid remain in the retentate. The pore size in the filter determines which substances are allowed through. The smaller the pore size, the higher the pressure in the system has to be. There are various types of filters; (polymer) spiral-wound tube modules, plate and frame modules, and ceramic filters. Highly filtered liquids are milk, whey, brine etc.

Options in addition to normal refurbishment

Conversion to a greater or smaller surface area by the addition or removal of filter tubes or plates. Potential to modify capacity and thickening level. Direct link to pasteurisation installation. Technology for cream cheese production, amongst others.

Assembly of complete filtration units. A unit consists of: Stainless steel frame. Feed and circulation pumps. Filter and balance vat. 1, 2, 3 or 4 recirculation loops included: Recirculation pump, valves, temperature and pressure transmitter or indicator, a minimum of one flow indicator for permeate, the filter module itself.

Possible: Cooler or heater (tube heat exchanger). The retentate system flow transmitter and control system to regulate outgoing flow. For CIP, dispensing pumps and potential flow transmitter for the cleaning fluids.

New control with the following options:

1. Simple manual control
2. Water automatically driven through product and vice versa
3. Run sterilisation, stabilisation, start, production, stop and cleaning phases automatically
4. Automatic dispensing, control and recording of lye and acid
5. Recording of temperatures and pressures
6. Standard control with Siemens PC and touchscreen control panel. Operation in a SCADA system is also possible
7. Signal exchange with CIP, reception and source tanks
8. Valves with valve position feedback (ThinkTop)

The advantage of frame mounting is that testing has already been completed. Just position the machine and begin without high installation costs.
