IntensaPulper facilitates efficient pulping of fibers from virgin pulp, recovered paper or paper machine broke in stock preparation.

The Intensa technology from Voith offers quick and intensive mixing of the suspension in the pulper. The flow-optimized pulper vat, in combination with the eccentrically arranged rotor, generates a perfect turbulence. As a result, quicker mixing of the suspension and accelerated bale intake are achieved. The double-coned bottom of IntensaPulper creates a flow-optimized transition from the pulper bottom to the cylindrical trough wall.
IntensaPulper IP-R is specifically designed for the pulping of recovered paper at a high pulping consistency. The rotor configuration ensures a reliable ragger operation, and the number of ragger breaks can be reduced to once a month. The double-coned bottom combined with the baffle urges the coarse heavy contaminants towards the reject discharge allowing a reliable removal in the Junkomat.
IntensaPulper IP-V enables efficient pulping of virgin fibers, clean recovered paper or broke in batch or continuous mode. A bale breaker divides the bales and thus contributes to an increase in production capacity. A trap for heavy parts ensures the separation of wires.
IntensaPulper from Voith achieves a significant increase in production capacity, while keeping the pulping quality consistently high. Significant energy savings of up to 25% are obtained in comparison to conventional low consistency pulpers, thus high cost savings can be achieved.
The particular orientation of the rotor-screen unit on the top of the asymmetrically shaped tank ensures that no vortices can form inside IntensaMaXX. Development of spinnings is thus successfully counteracted, and even maximum contaminant contents are not a problem. Reject discharge in a downward direction ensures reliable removal of contaminants. IntensaMaXX with rotor type B is available for high levels of contaminants; rotor type S is available for hard-to-pulp raw materials.
IntensaMaXX can be used in continuous low consistency (LC) pulping with recovered paper grades containing contaminants or in high consistency (HC) pulping as a dumping machine after the batch HC pulper.

The CompactPulper ensures reliable pulping of broke through improved rotor contact and a higher circulation rate. Thanks to its narrow and compact design, the CompactPulper requires minimal space and is used with couch and press broke and with dry broke at a pulping consistency between 3% and 6%.
An effective agitation with low vat height, together with an intensive rotor contact results in a higher circulation rate providing a more intensive pulping with simultaneous low energy consumption. The CompactPulper is available with one to four pulping units per pulper vat and with a width of up to 12 meters. Each pulping unit provides an electrical power of between 55 and 900 kW.
In conjunction with the IntensaPulper IP-R, the ragger transports the tail, formed from bale wires and other coarse spinning contaminants contained in the recovered paper, from the IntensaPulper. To form a sufficiently stable tail, a sufficient quantity of contaminants, such as typically occur in the OCC raw material need to be continuously fed to the IntensaPulper IP-R.
Bale wires are necessary for the transportation of paper bales but expensive to remove upstream of the pulper, and this is not a functioning solution, because there are still spinning contaminants in the recovered paper that form huge spinnings in the pulper that can only be removed by an orange peel grapple. This is why the ragger is a simple tool for removing the spinning materials from the IntensaPulper IP-R. It ensures that the steel wires are not broken down by the rotor and then cause excessive wear on machines, valves and pumps.
Correctly positioned and in combination with the rotor of the IntensaPulper IP-R, the number of torn off tails can be reduced to a minimum. Strong ribs on the transport wheel prevent slippage.
The ragger produces 1.6 tons of tractive force with a 1.1 kW motor. During breaks in operation the brake integrated into the motor stops the transport wheel from twisting. Forward and backward transportation of the ragger is possible with push buttons. The high gear ratio allows an intermittent speed control from 10 to 300 m/h.
