Parason Hot Disperser system is designed to Disperse the specs & impurities (waxes, hot melts, stickies, bitumen, ink) contained in the waste paper pulp. The technology lies in the combining of the forces such as high consistency of pulp at 38 % to 42%, raising the temperature to 80° to 110° and applying the mechanical energy by Ultra Precision Disperser segments in the accuracy of microns. At this stage, the combination of the various forces creates the balance, so that the aesthetic properties of the paper are improved dramatically.
ADVANTAGES OF DISPERSER
- Reduces specs in pulp
- Can use cheaper waste paper
- Improves fiber treatment
- Reduces stickies, hot melts etc
- Improves paper quality
- Reduces raw material cost
- Provides better strength property
- Increases paper machine runnability, reduces machine clothing costs
OVERALL INCREASE IN PROFITABILITY
OPERATION SYSTEM
- The Parason Disperser system consists of the following combinations of the processes:
The stock consistency needs to be increased upto 38% – 42% - Breakage of the lumps in the pulp will increase the surface area
- Increase the temperature of the pulp to 80°C – 110°C
- Ultra-Precision dispersion with precise gap control
SCREW PRESS
The Parason Screw Press is very sturdy and has a unique feature. The screw is made in single piece casting with hard facing edges of the flights. Pulp stock outlet consistency is upto 38% – 42% after Screw Press.
SHREDDER
Thinckened stock is shredded uniformly to increase the surface area of pulp stock. It helps steam to penetrate into pulp stock evenly
INFEEDER
The Infeeder screw feeds the stock uniformly to the disperser
PARASON DEWATERING SCREW WITH PNEUMATIC LOADING SYSTEM
Parason dewatering screw which has both conical screw cone and pneumatically controlled counter pressure cone that ensures desired dewatering effect upto 10% consistency with flexibility of operation.
PLUG SCREW
Plug screw is designed to avoid escaping of steam, thus reducing the steam consumption and improving the dispersing effect. The screw consists of an inlet chute tapered compression zone
HEATER MIXER
Shredded stock heated to 90°C – 100°C in Heater Mixer with temperature control system. Steam nozzles are provided throughout the length of Heater Mixer for uniform heating
DISPERSER
Parason Hot Disperser is designed for dispersing of pulp stock at 30% consistency, 100°C and gap control upto 0.01 mm accuracy with electro hydraulic arrangement. Designed for gentle treatment of fibre at high consistency and temperature, ensuring optimum development of fibre and dispersion of contaminants in microns, hence improving aesthetic look of paper.
