This machine is intended for semi-automatic opening of any type of sack (exept aerosils), limiting the operator’s movement only to placing the sack in place. The degree of confinement of the machine that operates with the door closed, installation of a sack compactor and connection to the dedusting piping minimize fine particles emission to the atmosphere (a dedusting unit is optionally proposed). It guarantees operation in a dust-free environment, without the need of cutting sacks manually.

Electrical power  
Feeding conveyor (option) : 1,1kW(1,5HP)
Driving motor of the cutting head : 1,5kW (2HP)
Compactor and internal conveyor : 2,2kW (3HP)
Fan motor (option) : 1,5kW (2HP)
Vibrating motor (option) :  0,25kW (0,3HP)

The machine comes with a complete panel control to ensure the requested rates.

rotary nozzle cleaning

CIP (clean in place)

The introduction of nozzles within the machine ensures, after the opening phase, a complete automatic cleaning of the equipment.

A few nozzles are located in order to clean the complete machine and thereby ensure no cross-contamination.

The drying process by hot filtered air (H14) is also offered by the design office Palamatic Process.
