Press-filter with chamber ALFA MAGIC

Alfa Magic is a press-filtering system with chambers that separate the solid particles from the fluid. Particularly, Alfa Magic is appreciated in the wine industry – to separate the must from the fermentation and decantation lees – and in the brewing processes, as well as in all applications that imply filtering through separation/extraction.


  • Food and beverage, in general
  • Wine and brewing
  • Sludge dewatering in the chemical, mineral, and extractive fields
  • Sludge dewatering from sewage and waste-water in urban contexts

Operating principles

The Alfa Magic (F-14) system is based on a “filtering pack” made of a central, self-holding frame on which is inserted a series of vertical plates, sized from 40×40 up to 150×150 centimetres. These filtering plates can be concamerated plates, inflatable membrane plates, or intercalated plates-and-frames elements.

In the concamerated-plates press-filter, the product is fed through a central hole and then passes through the filtering plates: the filtered result is collected in the corners, while the solid elements are trapped in the chamber created by the union of framed plates.

In the press-filter with inflatable membrane plates, the principle is similar, but it adds the possibility to create pressure by insufflating air or water, thus “squeezing” the trapped solid to fully extract the filtered byproduct and for the quick drying of the filter cake residue.
The filtering process is obtained through the alternatively coupled full plate/framed elements.

The framed elements create a space (chambers) in which the solid residue is collected and pressed, creating the typical filter cake waste.

Alfa Magic press-filter can function manually or automatically. In the latter option, all phases are automated and the operator’s input is only necessary for control and to manage the process of opening and discharge of the filter cake waste. These, once filled, can be gathered and moved through collecting bins or through belt or screw conveyor systems, depending upon the specific needs.

The final cleaning can be conducted manually or through automated systems with high pressure nozzles.
