Clarifying Wine

Recovery and filtration of tank lees with the dynamic crossflow filtration (DCF) 


Every drop counts in oenology. With its dynamic crossflow filter (DCF), ANDRITZ Separation provides a highly efficient separation solution that is superior to common technologies like vacuum drum filters or filter presses.


A DCF skid is plug-and-play solution for sustainable lees recovery, increasing the plant yield and, at the same time, reducing the volume and mass of waste streams.


Thanks to its small dimensions, the DCF skid not only provides very efficient separation technology but is also a very compact and space-saving unit, benefiting from its vertical layout.

You'll benefit from:

Higher Yield - Up to 98% of wine processed.

Save money on consumables - There's no need for filter aids, minimizing costs for consumables and their disposal.

Direct Bottling - Filtered wine has top quality with regard to Vmax, IF, or IFM, allowing direct bottling, no loss of alcohol, CO, flavour, or taste.

No O pick-up - Due to self-venting design through vertical shafts.

Reduced energy consumption - approx. 7.5 kW for 10 hl/h.


The skid is already equipped with a wide range of process instruments, which means there is no need for Recovery and filtration of tank lees with the dynamic crossflow filtration (DCF) additional installations.


Operation of the unit itself is very easy because the DCF skid runs in a continuous and stable process in which no diatomic earth or other filter aids are needed.


Tank lees recovery during vintage or wine purification is only one of the various applications of the DCF skid. It is a smart solution to increase yield, optimize quality, reduce costs, and improve working conditions.
