Vogelbusch Glucose Technology<\/h2>\n

Glucose, also known as dextrose, is a natural sweetener, which is obtained from starch containing plants such as corn, wheat, rice and cassava.<\/p>\n

As a liquid intermediate product, glucose syrup serves as a feedstock for fermentation processes<\/a> and it can be further processed to gain sorbitol or fructose. Crystallization of glucose syrup produces dextrose anhydrate or monohydrate, which are used in foodstuff as a sweetening agent, and in medical applications.<\/p>\n

Starting out from starch milk, we design and supply plants for the production of liquid and crystalline types of glucose.<\/p>\n\n

\n Vogelbusch process for glucose production from starch milk\n <\/h3>\n
\n

Starch is processed into glucose, a high DE (dextrose equivalent) starch sugar, that can be further processed into other types of starch sugar and to biobased chemicals.<\/p>\n

Conditioning of starch milk<\/p>\n

\n RAW MATERIAL PREPARATION\n <\/h3>\n
\n

The feedstock for glucose production is starch milk at a purity ranging from 98 to 99 % of starch in dry substance. <\/p>\n

Starch mixed with process water is buffered in a starch milk vessel to allow homogenization of the starch slurry.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n \n

Hydrolysis<\/p>\n

\n BIOREACTION\n <\/h3>\n
\n

Conversion from starch to sugar is carried out as a two-step enzymatic process.<\/p>\n

In the liquefaction<\/strong> step, the starch slurry is treated with enzymes and fed to a jet cooker, where the starch is pre-liquefied. This solution is cooled down in an expansion vessel and placed in an intermediate storage tank for final liquefaction.<\/p>\n

In the saccharification<\/strong> tanks, further enzymes are added to convert the dextrin into glucose and minor amounts of higher sugars (maltose, isomaltose, maltotriose etc.). By carefully selecting the process parameters, DE values of up to 98 can be reached within 30 – 60 hours of saccharification time.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n \n

Purification<\/p>\n

\n PRODUCT ISOLATION AND CONCENTRATION\n <\/h3>\n
\n

For the separation of suspended particles such as fibers and proteins Vogelbusch offers a broad range of filtration<\/strong> technologies. State-of-the-art cross flow membranes can be employed with the aim to recover the separated solids as a valuable animal fodder. Filter presses, vacuum drum or disk filters still form a cheap alternative and hence are widely used mainly for processing low DE syrups.<\/p>\n

Deashing of the filtered solution is done in a pair of strong acidic and weak basic ion exchangers<\/strong>. Color bodies and foreign tastes are reduced to a minimum by activated carbon treatment<\/strong>. This is done either by passing through vessels filled with granular activated carbon or by suspending and subsequent filtering of the activated carbon powder.<\/p>\n

To concentrate the solution, a finely tuned system of multiple effect plate type or falling film evaporators<\/strong> is deployed. It is heated by steam and powered by mechanical or thermal vapor re-compression, thus ensuring utmost energy efficiency in combination with minimal thermal stress for the product.<\/p>\n

The final dry substance content is adjusted to the market demand, or to the subsequent processing steps.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n \n
