The most common form of household sugar is white crystal sugar that has been purified through refining – fine crystals of around 400 microns are typical. The ball-milled type involves putting the sugar in a mixer with lots of steel balls inside.
Coarse Grain Sugar is used mainly for manufacturing and decorating baked goods and confectionery products. Before then, crystal size measurement was done manually by measuring sugar crystals under a microscope, which is time consuming and lacks reproducibility unless a large number of crystals are counted. Its fine crystals can no longer be sensorily perceived and are used as a basis for fine desserts or for icing.© 2017-20 Copyright by Sympatec GmbH | All rights reserved.This site uses cookies and related technologies – more details also about your user rights can be found in our Click “Accept and continue with default settings” to accept cookies and directly access the website, or click “Show cookie settings” for a detailed description of different cookie types and/or to adjust your cookie selection. A consistent quality and quantity of seed crystals is important to operate the sugar crystallization efficiently. The size ranges from 14 microns to 428 microns with an overall average median of 184 microns. Batch #2 has a considerably coarser average final grain size of the sugar crystals of over 450 microns for a significantly longer service life. Other important factors found to provide consistency for the seeding are proper (dry) storage of powdered sugar, proper mixing and sufficient ball milling time (minimum four hours for powdered sugar, five hours for granulated sugar). More than a third of the U.S. domestic cane sugar production, 1.4 million tons, is grown and processed into raw and white sugar in Louisiana.
The basic processing steps at each of the 11 raw sugar factories in Louisiana are milling and extracting the juice from the cane, then clarifying and concentrating the juices to syrups.
Sucrose consists mainly of sugar cane or sugar beet. The size of the C-sugar is also relevant for overall sugar recovery because C-sugar is the last sugar crystallized before the syrup becomes blackstrap molasses (used for animal feed), and no further sugar can be obtained from it. The growth of the crystal size from an average of approximately 50 microns to nearly 350 microns (x50 value) in batches #1, #3 and #4 is clearly apparent. The crystals are then filtered or centrifuged, washed and dried. The purity rise ranges from 3.5 to 6.5 with seemingly no direct correlation to the crystal size. All are suspended in isopropanol. More than a third of the U.S. domestic cane sugar production, 1.4 million tons, is grown and processed into raw and white sugar in Louisiana. Crystallised sucrose as large transparent crystals.

The economically most important sugar is the industrially manufactured sucrose (table sugar), which is used as a sweetener and fast supply of energy. Three slurry types are typically used – powdered sugar, ball-milled sugar and ball-milled powdered sugar. Any losses to the blackstrap molasses are final. The longer it takes to form the granule the larger the granule of sugar. The diagram shows the results of an in-situ measurement with an OPUS ultrasonic sensor for four consecutively running batch crystallisations of pharmaceutical grade glucose. Is good advice hard to find? While there are many factors contributing to the purity rise, it is clear that a low purity rise is rarely achieved with small crystal sizes. 10 percent of the mass of all crystals are below this size. However, the data exhibit no points in the lower left corner of the graph, where low purity rises (low loss to molasses) would be achieved with low crystal sizes.
The crystal size and uniform distribution of the C-sugar are therefore important because affect production into commercial raw sugar. As the instrument assesses diffractive properties, it measures a size-equivalent sphere, giving a better volume representation than the two-dimensional measurement under the microscope. The modern practice in sugar crystallization is to use full seeding, where every crystal is deliberately initiated with a seed crystal from seed slurry. Challenge us and fill us in on the details of your application. Size matters when it comes to sugar crystals and the efficient processing of cane juice into refined sugar for human consumption. Ball-milled seed slurries have substantially smaller crystals with a D90% of only 19 microns providing at least 10 times more seed per gram of sugar than powdered sugar. Figure 1 shows the variation of the measured C-sugars for the 2015-2016 season for all 11 raw sugar factories. 106 Martin D. Woodin HallSize matters when it comes to sugar crystals and the efficient processing of cane juice into refined sugar for human consumption. D50% is a descriptor also called the median, and D90% describes the largest crystals in the distribution.
