VACUUM PANS

NSI Equipment Pvt. Ltd. Vacuum Pan produces high massecuite exhaustion, consistent crystal size and improves energy efficiency.

A vacuum pan is essentially a vessel, operated under vacuum, in which sugar syrup is boiled in order to increase the sugar concentration, and thus resulting in the formation of sugar crystals, resulting in a suspension of crystals within the mother liquor from which they are growing (so-called massecuite).

Designed in-house by NSIE’s world-renowned experts, NSIE Vacuum Pan designs are suitable for A, B and C massecuite and are configured to optimise upstream and downstream plant capabilities.

NSIE Vacuum Pan designs are available in a custom designed to specific factory requirements. Importantly, the pan’s vapour demand is surge-free and consistent with steady-state boiler operation and evaporator performance for extended periods.

NSIE Continuous Vacuum Pans are designed to:

• Produce strong massecuite circulation

• Provide uniform conditions for crystal growth at any section along the pan

• Generate narrow crystal size distribution

• Minimise the number of control instruments

• Provide easy access to calandria for maintenance

• Simplify valve and feed pipe work

• Augment production capacity by the addition of an extra module

• Maintain consistent production performance with minimal operator supervision

• Produce rapid and simple emptying, boil out and restart operations.

Design features of NSIE’s Continuous Vacuum Pans include:

• Horizontal pan layout comprising well-mixed cells

• Carefully designed massecuite flow path to avoid flow restrictions

• Small number of cells of optimal individual cell volumes

• Separate modules with calandria in each module

• Low massecuite boiling head

• Optional mechanically stirred modules
