The liquefaction process of production of glucose syrup from starch
Liquefaction process is one of the most important part of the whole starch syrup production line and let's take a look at the following:
Put the starches slurry into the mixing tank. Sometimes you will find mixing tank surface with brown floater, it is likely to be excessively high protein content. It will cause high dosage of activated carbon, increasing the load of ion exchange, and reducing the service life of ion-exchange resin, so we must ensure that the starch milk protein content is below 0.5%.
In order to make full use of the mother liquor, the part starch milk can be recycled in the mixing slurry process, and the normal return amount can reach up to 2/3. The overuse will affect the quality. Average concentration is 35% - 36%. Mixing temperature is 29 ℃-34 ℃. Then putting starch slurry into the ejector, large and medium-sized enterprises flow rate is 25-40 m3 / h; steam pressure is 0.4 Mpa; liquefied liquid temperature is 99 ℃. After that entering the laminar flow tank for heat preservation of 60 minutes, and then into maintaining tank. Put the liquefied liquid into the second ejector. The steam injection pressure control is 0.2 Mpa; the temperature control is 130℃ to 134.6℃. Liquefied liquid will come into the high temperature maintain tank and then secondary flash cooling tank. The liquid temperature lower 64℃ to 60℃ to neutralize, then coming into the neutralization tank, adjusting the pH value to 4.4-4.5 for preparing glycosylated.
Multiple-effect film-falling evaporator concentrates the solution by means of vaporizing the thin solution through film-falling principle. It introduces continuous production and it features in high concentration ratio, large viscosity scope, good heat-transferring effect, large processing capacity, etc. In this case, it can be introduced on vaporizing materials which are of high heat sensibilit, high concentration, high viscosity, and corrosive characteristics. This equipment is of higher heat-transferring ratio, so the heat difference requested is small. It can be combined into double, triple, quadruple, or quintuple, or quintuple-effect evaporating system on the basis of different materials characteristics and evaporating results.
In addition, it can be used as waste-heat evaporator with the resources of waste steam from bundle dryer, disc dryer or other heat resources with low thermal value such as condensate steam. In this way, raw steam consumption can be greatly reduced for energy saving. It is economically beneficial when waster steam can be completely used and raw steam is saved.
Product characteristics of evaporator during glucose syrup processing plant:
1) Implementations of automation systems, computer 2D/3D modeling and advanced CAD/CAM technology.
2) Turn-key plants for the production of wheat starch, corn starch, potato starch and starch derivatives such as glucose, fructose, crystallized glucose, sorbitol, etc.
3) Professional engineers with ample on-the-job training experience.
4) A team working at site for the guidance of installing, commission works.
5) Low water and low energy consumption design to save your money.
6) Equipments are made of stainless steel, one year warranty, life-long maintenance.
