Candle Filters work on the basis of pressure. The fluid to be filtered is forced through a vertical filter (candle). The solids in the fluid being filtered cakes on the filter candles until flow is decreased and pressure starts building. At that point, a pulsed air or nitrogen (gas) in reversed flow, causes a rapid deflection of the filter cloth of the candle and the immediate detachment of the cake, where they drop to the bottom and fall out of the filter.

The candles can be made out of a wide variety of materials, depending on the material being filtered.

In the Candle Filters, solids are removed from the slurry as the fluid passes through the filter media from outside. So as the cake grows on the outside of the cylindrical candle filters surface, the surface area also increases. This means that the cake thickness grows more slowly than it would on a flat-faced filter, and results in a more linear change in pressure and flow rate.

Another feature of Candle Filters is the cylindrical shape of the elements that retain the formed cake. This shape, opposed to Plate, Leaf or Filter presses, increases the filtration area as cakes grow thicker and compensate to some extent to the decrease in filtration rates.

Our Candle filters works continuously and automatically by PLC control and supervision.

Characteristics and Performance:

  • High solids filtration efficiency

  • Micrometric particle retention capability

  • Uniform filter cakes

  • Slurry or dry cake discharge

  • Fully automatic operation

  • Low operating costs

  • Made with FDA food grade materials

  • Closed loop system

  • PLC can be customized and integrated to other systems.

  • Made in Italy

The filter is constituted by a frame to fix the candle and the connecting pipes.

The candle is made by a flange plastic body and equipped with a bottom butterfly valve for the discharge of the material.

The flow of filtering solution and clean solvent is controlled and regulated by mean of an AODD pump with damper and a pneumatic or electric valve-system.

The compressed air circuit is equipped with a buffer tank and pressure regulation device.
