ROCKET
Dynamic rotary filter
Rotating 0.2-micron ceramic discs for clarification lees, flotation lees and cross-flow residues. No filter aids. Pat. appl. no. TV2013A000032.
The ROCKET unit is suited to filtering products such as clarification lees from juice, must or wine, flotation lees and residues from cross-flow filters.
It causes no heating or denaturation of the product and no loss of colour or alcohol content, thanks to a low-pressure filtering process and a stabilised filtering medium.
Low power consumption, small footprint, ease of use and a fully autonomous process.
The process
Filtration takes place on semi-permeable ceramic discs fed at low pressure and constant flow, with a nominal pore size of 0.2 micron and without filter aids such as kieselguhr. The product passes through the filtering medium leaving the solids on the outer surface; the liquid that permeates the disc is collected by a central manifold.
The discs are kept in constant rotation so that their outer surface cleans itself, ensuring long-lasting filtration at a constant flow rate. A back-wash with the filtered product itself is also provided.
