What is glucose? Glucose – in USA called dextrose - is the most important carbohydrate for applying energy in human beings and is found all over in nature. Glucose is used very much in the industry as concentrated liquids. In commercial scale by enzymatic or acid hydrolysation the glucose is made from hydroxylation of starch followed by purification, fractionation by ion-exchange and
membrane filtration and concentration by
evaporation. The crystallizing process
The concentration is done in a
falling-film evaporator. Huge amounts are also used as crystallized powders. The glucose can easily crystallise as a monohydrate from water or as anhydrous glucose from ethanol or warm water. The glucose is crystallixzed in big
crystallization tanks. The crystals are separated in a
decanter and dried in a
VIBRO-FLUIDIZER™. The mother liquor is disposed of as a waste. Glucose is sometimes made as
spray dried powders, when special properties are required.
By the hydrolysation of starch a product with 92-98 % glucose can be obtained as ‘Total Sugar’. This product is filtered and cleaned through active carbon followed by evaporation to 60-70 % sol-ids in a
falling film evaporator and can as a concentrate be used as it is. It can also be crystallized and dried as described above.
As the mother liquor is a loss in the crystallization process, the ‘Total Sugar’ can also be spray dried in
a FILTERMAT™ with a huge recycling of product – enhancing the crystallization and reducing deposits- to the drying chamber. Final crystallization is done in crystallization drums.
