3 THE SEEDMASTER 2 CRYSTALLIZATION TRANSMITTER AND SEEDING
DEVICE
3.1 SeedMaster 2 description
The heart of SeedMaster 2 is a high performance computer specifically designed to calculate, display and
transmit all of the vital parameters characterising sugar crystallization simultaneously for up to 2 crystallizers.
Besides that it can perform reliable automatic seeding of the crystallizers as well. Both features require the
input of some data measured on-line by 1 (or 2) K-PATENTS process refractometer(s) and by some selected
instrument(s). Input of a few laboratory data and status information (digital inputs) are also required.
Based on these data SeedMaster 2 is able to calculate 7 massecuite parameters per crystallizer in real time,
only 2 of which are considered adequate for the advanced control of crystallization.
Some of these parameters (for example: crystal content, mother liquor purity, mean crystal size etc.), though
they are important ones, are usually rarely determined by the local laboratory, if at all. Due to the time delay
(dead-time) involved, these data, however, are more or less useless in closed loop, real time control of
crystallization.
Other instruments in use provide data only on a single massecuite parameter.

3.2 SeedMaster 2: a front-end device
The device was designed to be used as a “front-end” instrument mounted close to the vacuum pans or
crystallizers in order to provide all of the information required by operating personnel on site. It has a large
backlit LCD display and a keyboard (Fig. 3.2). Naturally enough, it has advanced digital communication
features to send a large amount of acquired and calculated data on-line to a Process Control System, too.
The LCD display is specified to operate in the 0 – 50 C temperature range (environment) and this applies to
SeedMaster 2 as a whole, too.
