[0065]

[0066] Compared with the beet sugar clear juice before nanofiltration treatment, the obtained concentrated clear juice has a brix increase of 6.1Brix, a 5.6wt% increase in sugar content, and an increase in purity of 1.38 percentage points; after calculation, nanofiltration can reduce the evaporation load by 37.9% . In the present invention, the "evaporative load reduction percentage"=[1-(water content in the concentrate after nanofiltration treatment÷water content in clear juice before nanofiltration treatment)]×100%.

Abstract

The invention relates to a method for concentrating and purifying beet sugar manufacture clarified juice. The method comprises the steps that 1, the beet sugar manufacture clarified juice which is suitable for nanofiltration is obtained; 2, the temperature of the beet sugar manufacture clarified juice is reduced to be not lower than 30 DEG C from about 90 DEG C; 3, the beet sugar manufacture clarified juice is filtered and concentrated through a nanofiltration film with the molecular weight cut off of 220 Da to 500 Da under the pressure of 10 Bar to 40 Bar, thereby obtaining the concentrated and purified beet sugar manufacture clarified juice. The invention further relates to a sugar making method comprising the step 1 to the step 3. The brix of the concentrated clarified juice which is obtained through the method for concentrating and purifying the beet sugar manufacture clarified juice is improved by 4 Brix to 7 Brix, the sugar degree of the concentrated clarified juice is improved by 4wt% to 7wt%, the purity of the concentrated clarified juice is improved by 1% to 2%, and the evaporation loads of the concentrated clarified juice is reduced by 30% to 50%.

Description

technical field [0001] The invention relates to a method for applying membrane separation technology to the purification and concentration of beet sugar clear juice and a sugar production method using the method, belonging to the technical field of sugar beet processing. Background technique [0002] Sugar beet is one of the main raw materials in the sugar industry, and its roots have a high sugar content. Chinese sugar beets are mainly planted north of 40° north latitude, including the three major production areas of Northwest China, North China and Northeast China. Among them, the northwest production area has the characteristics of long sunshine, so the production and sugar content of sweetmeat are relatively high. [0003] The sugar beet sugar production process mainly includes washing vegetables, shredding, juice extraction, clarification, evaporation concentration, evaporation crystallization, separation of molasses, white sugar packaging and other processes. Because...
