HEEL BREAK- UP SYSTEM FOR COMPLETE RESIDUAL REMOVAL


 

This system has been introduced and developed by COMBER with the aim to improve the product discharge and to reduce the residual one. This technology produces the break-up of residual product remaining on the filtering element through Nitrogen blowing from the base.

The original idea was to split the multi layer filtering element in several sectors; in this way the Nitrogen counter-blown by a series of nozzles (not in contact with the product) can act on each single sector. Nitrogen blasts are introduced in sequence, individually on each sector, between the filtering base and the perforated plate.

The aim of this system is to obtain the complete/total removal of product residuals.

 

On larger Filters the system is divided into several sections for maximum system efficiency.

Bursts of nitrogen are introduced from underneath the filter element, breaking the heel for easy removal Pressofiltro® Heel Break-up System. This system is designed to break-up the heel remaining on the filter element after discharging the filter for maximum product yield/recovery. Bursts of Nitrogen are introduced in the space below the filter bottom and the perforated filter support plates with the filter element. This breaks up and loosens the heel on the filter surface for a more complete and efficient product discharge by the agitator.

These bursts are introduced in sequence to the individual filter element sections installed. The system includes a jacketed Nitrogen accumulator vessel, control valves and all associated piping.

Whirl Snake - Total Heel Removal
 

This system is designed to discharge heel remaining on the filter cloth after discharging the filter for maximum product yield/recovery.Using Nitrogen any remaining product on the filter plate is blown towards the discharge port. With the shaft rotating in addition to the rotating nozzie head all vessel areas are covered assuring full removal of remaining product.

The combined rotating action of the shaft and the nozzle head assures all areas of the vessel interior are covered by the Nitrogen blast, assuring all product is removed from all areas within the vessel.

The same system can also be used for the CIP cleaning and the subsequent drying of the vessel.
