Continuous Vacuum Pans

Design Features:

1. Save space & energy
2. Low temperature vapour boiling
3. Good Massecuite circulation
4. Uniform condition for crystal growth in all section
5. S.S. Polly baffle catcher is provided for entrapment raster
6. Increase production capacity about 25% than the batch pan for same volume
7. Easy for operation.
8. Maximized exhaustion of mother liquor.
9. Following Major factor were kept in view while designing the continuous vacuum pan.
10. Better circulation & efficient heat transfer to achieve improve evaporation rate.
11. Narrow crystal size distribution.
12. Small coefficient of variation.
13. Steady & less steam demand.
14. Plug flow and massecuite.
15. Short Retainsion of crystals in pan
16. Pan can be boiled with low pressure steam / Vapour.
17. Less steam demand / consumption.
18. No fluctuating steam demand as is in a batch pan operation
19. Greater uniformity in operation is obtained with respect to crystal size and exhaustion.
20. Number of units like condensers and ancillaries are reduced and thus less maintenance cost.
21. Labour Saving.
22. Operation Control is easy due to DCS based Automation system.
