Batch cooking
Batch cooking is the right choice for dissolving pulp grades. A system with high availability and capabilities for various dissolving grades. Valmet’s batch cooking system is also a viable option for wood based kraft mills designed for smaller capacities.
Quality and production reliability are the key factors for dissolving pulp production. Valmet batch cooking process effectively removes any scaling formation during every cooking cycle enabling a continuous dissolving wood pulp production with high and uniform pulp quality every day.
Advantages of batch cooking
- High production reliability especially for DWP
- High and uniform pulp quality especially for DWP
- Possibility to run high-alpha pulps for DWP
- Steam hydrolysis – low volume, high DS to evaporation
- Low maintenance cost
