Sugar refinery controlled by sugar crystallization process improve profitability
A Thai sugar refinery use visa, K - PATENTS ® SeedMaster SM - 3 optimized batch vacuum crystallization boiling sugar, crystal quality and yield, and benefit from it.The sugar refinery process control solutions provided by Contrologic company and debugging.
Automatic control goal is to reduce the batch in the process of boiling sugar for the use of steam and water, at the same time, through strict control of crystal size distribution (CV) and average particle size (MA) to improve the quality of sugar.This goal can be fully automated control strategy based on degree of supersaturation of real-time control implementation.
, for example, by comparing the yield, energy consumption and the crystal quality of before and after the strategy, we found that, before the implementation of 85 m3 boiled sugar pot (see figure 1) per batch cooking sugar can use 7 m3 of water.
Figure 1. Vacuum sugar pot cooking (85 m3).
In prior to the implementation of the water used to remove new, small crystal don't need.Introducing process control solution not only eliminated the need for water, will also reduce the steam consumption by 25%, while the yield increase by about 1%.

Why should based on the degree of supersaturation control boiled sugar?
High quality of sugar production is dependent on the crystal growth, and promote the supersaturated impetus for crystal growth.Crystallization speed is a function of multiple parameters.Degree of supersaturation is defined as: the actual sugar concentration of mother liquor with the same temperature of the ratio of saturated concentration of sugar.
There is a range of degree of supersaturation in this range, sugar crystals evenly and widely, the crystal grain size required.Outside this range, the crystal will stop growing, natural melting or may even begin to form a new crystal, produce need to rework glue powder and crystal., it will bring significant impact, because this will lead to waste of time and energy, increase the cost of production and water consumption, and reducing sugar production effectively.
In order to develop to solve these problems based on the degree of supersaturation solution, the control of the factory for boiled sugar jar is equipped with visa K - PATENTS ® SeedMaster SM - 3 system, the system can provide real-time data for saturation calculation.SeedMaster designed for sugar crystallization application scenario.The system consists of online refractometer and multi-parameter monitoring equipment, can provide the boost required for sugar crystallization parameters, and can support the implementation of automatic control of the solution.
Why customers choose visa SeedMaster?
Improve product quality and consistency
The quality of sugar is very high, and the quality of the consistent between different batches.By optimizing, and ultimately the amount of sugar in molasses got reduced, at the same time, CV/MA has improved.
The steam consumption by optimizing raw material and save a lot of cost
The consumption of raw materials to reduce operational cost savings can be realized, but cost savings from reducing steam consumption.Before using SeedMaster implement automation control strategy, the Thai sugar refinery steam per pot boil sugar consumes 39.4 ton, and after implementation, each boiler steam consumption of sugar dropped to 29.5 tons.
Because of the sugar manufacturing every step need water, so it is cumulative number.Sugar mill to produce steam used for processing, and will not run out of steam in the form of electricity sold to the grid.Control of the production process and optimize the factory can sell more electricity to the grid.
To reduce false crystal rework
Sugar crystal size is consistent, it reduces the time and cost associated with pseudo crystal rework.
Reduce the manual operation tasks
SeedMaster SM - 3 degree of supersaturation of automated control, means that the operator is no longer need to spend time sampling and perform other manual tasks.
Process control need to control process and equipment:
- Using a digital online refractometer concentration control
- Absolute pressure control
- Liquid level control
- Microwave density meter
Instrument and three control level of PID controller
