Design and Operating Criteria for Maximising the Benefit of Continuous Vacuum Pans

Broadfoot, Ross (2005) Design and Operating Criteria for Maximising the Benefit of Continuous Vacuum Pans. In Hogarth, D.M. (Ed.) International Society of Sugar Cane Technologists Proceedings of the XXV Congress, 30 January - 4 February 2005, Guatemala, Guatemala City.


CONTINUOUS vacuum pans provide significant advantages in achieving more effective use of installed volumetric capacity than batch pans. Other advantages are reduced supervision, benefits to steam economy and consistency in the composition of the product massecuite. However, in order to maximise the benefits, continuous pans must be operated at high sucrose deposition rates and be able to minimise the effects of any shortcomings such as time off line for cleaning. The paper discusses several important design and operating criteria for maximising the benefits of continuous pans to overall factory operation. Data are presented from operating continuous pans to highlight the importance of these criteria. Such data include circulation velocity measurements for the massecuite flow, residence time distribution data, massecuite exhaustion and crystal quality data. Consideration is given to design changes for future installations of continuous pans and ways to minimise the effects of downtime.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
