Embodiment Construction

[0010] Glucose production process, which includes decolorization, ion exchange, evaporation and other processes: add a plate heat exchanger before decolorization, through the heat exchanger, use 90 ℃ steam condensed water to heat the 35 ℃ glucose mother liquor to increase its temperature from 35 ℃ If the temperature is 65°C, reduce the amount of steam that needs to be heated to 85°C for decolorization. This part reduces the amount of steam by 1.75T / h.

[0011] After decolorization and before ion exchange, add a plate heat exchanger, heat the ion exchange output at 50 °C with the material at 85 °C after decolorization, and the ion exchange output after heating to 55 °C goes to the evaporator.

[0012] After ion exchange and before evaporation, a plate heat exchanger is added, and the evaporator output at 70°C is used to heat the ion exchange output at 55°C. After heating to 60°C, it enters the evaporator for evaporation operation. This process reduces the evaporator The steam c...

Abstract

The invention relates to a glucose production process, in particular to a glucose production process for reducing steam consumption. The invention aims at providing the glucose production process which fully utilizes the material temperature difference of the glucose processes to exchange material heat for reducing the steam consumption and saving energy and reducing comsumption. The technical scheme of the invention is as follows: the glucose production process for reducing steam consumption comprises: decoloration, ion exchange, and evaporation procedure; a heat exchanging system is arranged before decoloration, and through the heat exchanging system, the steam condensate is used for heating glucose solution. The benefits of the invention are as follows: the problem of high steam consumption in the current glucose production procedure is solved. The steam consumption for producing per ton of finished product of glucose is reduced by 0.28 t, and the production cost is reduced by 29.4 RMB.

Description

technical field [0001] The invention relates to a glucose production process, in particular to a glucose production process with reduced steam consumption. Background technique [0002] In the existing glucose production technology, the glucose mother liquor at 35°C needs to be heated with steam to 85°C for decolorization, after decolorization, it needs to be cooled to 53°C for ion exchange, and then it needs to enter the evaporator for steam heating to evaporate the material. A large amount of steam is used, and the steam consumption for producing one ton of finished glucose is about 1.4T, and the evaporated condensate is naturally cooled at 90°C and discharged to other workshops for use, wasting heat energy. Contents of the invention [0003] The purpose of the present invention is to provide a glucose production process that fully utilizes the material temperature difference in each process of glucose to exchange heat of the material to reduce steam consumption and save...
