Method for industrial production of glucose

Jun 25, 2018 / Industry news

About the method for industrial production of glucose, firstly, you need to know that the industrial production means that the capacity is large, the glucose products quality is high, so that this must produced by the mature glucose production technology and advanced design glucose production machine. So if you want to start an industrial production of glucose, except the plant construction, you also need to select a set of glucose production machine.

On the other hand, Doing Company is specialized in research of method for industrial production of glucose, professional to manufacturer the machine used for industrial production of glucose, also offer you the good technology which hydrolyse starch by enzyme, following is DOING method for industrial production of glucose detail introduction:

1. Raw material preparation-conditioning of starch milk:

Mixing tank

The feedstock for glucose production is starch milk at a purity ranging from 98% to 99% of starch in dry substance. Starch mixed with process water is buffered in a starch milk vessel to allow homogenization of the starch slurry. This part in industrial production of glucose main equipments adopted is mixing tank, after adding certain enzyme, and maintaining a certain temperature, starch slurry will became a transparent and sticky liquid, although stop stirring,the starch will not be precipitated. After this condition, we complete the raw material preparation.

2. Starch hydrolysis:

Conversion from starch to glucose syrup in industrial production of glucose is carried out as a two-step enzymatic process.

Enzyme added for starch hydrolysis

(1) In the liquefaction step, the starch milk is treated with enzymes and fed to a jet cooker, where the starch is pre-liquefied. Then the solution is cooled down in an expansion vessel and placed in an intermediate storage tank for final liquefaction. This liquefaction process function is convert starch milk into dextrin.

(2) In the saccharification tanks, further enzymes are added to convert the dextrin into glucose and minor amounts of higher syrup (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.

3. Purification-glucose isolation and concentration:

For the separation of suspended particles such as fibers and proteins, DOING offers a broad range of filtration technologies. In the industrial production of glucose, becaise the raw material adopted is large amount, the protein content in the starch also a large quantity. State of the art polymer, sintered metal or ceramic cross flow membranes can be employed with the aim to recover the separated solids as a valuable animal fodder. Plate frame filter press is a widely used machine for glucose isolation to get a clean glucose liquid, at same time, get the protein cake. Purifying of the filtered solution is done in a pair of anion-cation basic ion exchangers. Color bodies and foreign tastes are reduced to a minimum by activated carbon treatment. This is done either by passing through vessels filled with granular activated carbon or by suspending and subsequent filtering of the activated carbon powder.

To concentrate the glucose solution in the industrial production of glucose, a finely tuned system of multiple effect plate type or falling film syrup evaporators 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.

Doing Company will suggest you the most suitable syrup evaporator for you. About the industrial production of glucose, the final dry substance content is adjusted to the market demand, or to the subsequent processing steps. Finally, you can cilck glucose syrup making machine to know about the main machines used in the industrial production of glucose.
