Pulping Systems

The first operation to be carried out is that of pulping the fibrous material coming from virgin fibres, waste paper, or non-wood fibres in a tank that contains water, in order to separate the fibrous material into fibres at their elementary state. An impeller of various types and shapes, equipped with blades and placed on the bottom of the tank, creates a whirling motion that causes the used raw materials to flake off. The final product of this process are fibres in water suspension at about 5% consistency.

Toscotec Pulping Systems offer the possibility of selecting an optimal pulping technology according to the type of fiber used, the production, and the contaminant present in the fiber.

Medium Density Pulping includes the VP medium consistency pulper, which works discontinuously (aka “batch mode”) between 7% and 9% of cellulose, waste paper and non-wood fibres.

Low Density Pulping includes the low consistency TM pulper, which works continuously between 5% and 6% of waste paper with a high level of contaminants or rewinder trims.

Benefits:

• Having at its disposal both batch and continuous pulpers, Toscotec can select the best technical solution to optimize the quality of the pulped fiber and reduce energy consumption to a minimum.
• Toscotec pulper rotors are designed to optimize the pulping process, maximizing the pumping effect in the discontinuous medium density pulpers, or maintaining the right vorticity to optimize the cleaning process in continuous pulp.
