Vaisala K-PATENTS® Process Refractometers for Sugar Industry

Vaisala provides process refractometers for accurate in-line Brix and concentration measurements in the cane and beet sugar refining and milling processes. The purpose is to achieve high quality liquid and crystal sugars and to minimise costs of production. K-Patents refractometers are used:

  • to optimise extraction process and to minimize usage of water that needs to be removed from sugar juice later at the evaporator stage.
  • to adapt product flow to the capacity of the evaporators in order to save energy.
  • to make sure that liquid bulk sugar and molasses meet specifications.
  • to control feed juice to adjust the concentration with the capacity of the separation columns. This leads to longer intervals between recovering cycles and longer lifetime of the columns.
  • to monitor supersaturation over complete strike of crystallization.
  • to implement automatic and accurate seeding of the vacuum pan.
PR-23-AC Vaisala K-PATENTS® Sanitary Compact Refractometer PR-23-AC
For hygienic installations in small pipe line sizes of 2.5 inch and smaller. Installation through a 3A Sanitary clamp.
PR-23-AP Vaisala K-PATENTS® Sanitary Probe Refractometer PR-23-AP
For hygienic installations in large pipes, tanks, cookers, crystallizers and kettles and for higher temperatures up to 150°C (300 °F). Installation through a 3A Sanitary clamp.
PR-23-GP Vaisala K-PATENTS® Process Refractometer PR-23-GP
An industrial refractometer for large pipe sizes and tanks, cookers, crystallizers and kettles. Installation through a flange or clamp connection.
Vaisala K-PATENTS® SeedMaster SM-3 for Multiparameter Sugar Crystallization Monitoring and Automatic Seeding
A unique third generation crystallization transmitter and seeding device to be used with the K-Patents Process Refractometer. The SM-3 allows for accurate in-line and real-time monitoring of supersaturation and crystal content over the complete process of crystallization, and implementation and control of automatic or manual seeding.
