Advantages of continuous cooking system
- Lower energy consumption: lower steam and electricity consumption, without peak load
- Higher paper pulp production, smaller floor space
- Low consumption of per unit of chemicals
- More homogenized cooking and less rejects
- Easier to realize automation
- Low labor intensity
