Embodiment 1
[0161] The preparation of embodiment 1 refined white sugar
[0162] 1. The proportion of raw and auxiliary materials:
[0163] White sugar: deionized water: activated carbon: ethanol = 15:15:0.45:15 (mass ratio W / W)
[0164] 2. Preparation process
[0165] (1) Take by weighing 1500g of white sugar, 1500g of deionized water, 45g of activated carbon, 1500g of ethanol, and set aside;
[0166] (2) Put the weighed white sugar into the tank, add the weighed deionized water, stir and heat to dissolve at 80-85°C;
[0167] (3) Add the activated carbon that has been weighed, decolorize for 20-30 minutes, and filter while it is hot;
[0168] (4) concentrating under reduced pressure at 50-95° C. until the sugar content in the concentrated white sugar solution is 80% to 85%;
[0169] (5) When the temperature is lowered to 50-70°C, slowly add the weighed ethanol;
[0170] (6) Continue to cool down to 20-25°C, stir and crystallize for 3-4 hours;
[0171] (7) Centrifugal crystallized re...
