Bag dump stations

An additional option for some types of bag splitter is clean in place (CIP) operation. This is particularly useful for hazardous powders, and/or processes that use the same bag slitter for a number of different powders. CIP operation means that it is possible to completely clean the piece of process equipment without dismantling. 

Before using a particular material in either a bag slitter or a bag dumper it is recommended to check with the manufacturer as some hoppers may not be suitable. However, some examples of materials used in these devices are alumina, aluminium sulphate, carbon black, cement, cocoa beans, cocoa powder, coffee beans, flour, hydrated lime, lime, milk powder, potassium hydroxide, silica sand, sugars, talc, titanium dioxide and whole nuts (Aptech (Powder Systems) Ltd 2006 Hexicon Corporation 2006 Palamatic Materials Handling 2006 Spiroflow Ltd 2006 Vibrair 2006).

Palamatic, in addition to designing conventional bulk bag discharging systems, has developed another version ealled the Duo-Pal Dump Station which combines bulk bag and small bag discharging through a dust control unit. 

There are numerous bag handling systems available for filler users. These range from very simple saek dump stations to complieated lines handling up to 600 sacks per hour. The choice depends on investment and volume.
