Embodiment 1

[0008] A concentrated evaporation method for producing glucose, wherein: the dilute syrup enters the top of the first-effect evaporator after being preheated by the preheater from the discharge pump of the feed barrel, and after being distributed by the distribution plate, the dilute syrup flows along the inner tubes of the evaporator. The wall falls in the form of a film, and the mixture of dilute syrup and steam enters the I-effect separation chamber for separation, and then the dilute syrup in the separation chamber enters the II-effect evaporator and the III-effect evaporator through the pump to carry out circular concentration and evaporation; the steam is sent through the outer pipe into the I-effect evaporator, II-effect evaporator and III-effect evaporator, and the secondary gas generated in the I-effect evaporator, II-effect evaporator and III-effect evaporator passes through the I-effect separation chamber, the II-effect separation chamber and the III-effect separation...

Abstract

The invention belongs to the technical field of glucose production, and particularly relates to a concentration evaporation method for producing glucose. The method mainly solves the technical problems of high cost, short service life and narrow concentration range of the concentration evaporation method in conventional glucose production. The invention adopts the technical scheme that: steam is conveyed to an effect I evaporator, an effect II evaporator and an effect III evaporator through outer pipes; the secondary gas generated in the effect I evaporator, the effect II evaporator and the effect III evaporator is separated from syrup through an effect I separation chamber, an effect II separation chamber and an effect III separation chamber; and the separated secondary gas is sequentially compressed in two turbine compression fans and heated to form secondary steam, and the secondary steam is recycled in the effect I, II and III evaporators and provides heat for the effect I, II and III evaporators. The method has the advantages of low evaporation concentration cost, long service life and wide concentration range.

Description

technical field [0001] The invention belongs to the technical field of glucose production, in particular to a concentration and evaporation method for producing glucose. Background technique [0002] Glucose is widely used. In the glucose production process, the evaporation and concentration process of glucose solution is very common. Conventional methods include multi-effect evaporation and membrane evaporation. In membrane evaporation, the service life of the membrane is short, the operating cost is high, and the concentration range is relatively small. Narrow and other problems limit the application of membrane evaporation. At present, multi-effect evaporation is used more often. Many enterprises have adopted three-effect evaporation, three-effect evaporation, five-effect evaporation, etc. The increase in the number of evaporation effects has improved the evaporation effect, but The rapid rise of steam prices has increased the energy consumption of multi-effect evaporatio...
