How is white sugar made?

White sugar is extracted from sugar cane or sugar beet.

Taking sugarcane as an example, there are mainly the following steps. First, sugarcane pretreatment. Pretreatment means cleaning, chopping and crushing sugarcane. Second, squeeze. The pretreated sugarcane is sent to a press for pressing, and the sugarcane is divided into juice and bagasse. Third, clean the sugarcane juice. Just squeezed out, this is only turbid, and there are many impurities besides the main ingredient sucrose. Cleaning sugarcane juice is divided into filtering insoluble impurities (sugarcane chips, sediments, etc.). ) and precipitate soluble impurities (various organic salts, colloidal substances, inorganic salts, etc.). ). When precipitating soluble impurities, it is necessary to add chemicals to precipitate impurities, and then separate the precipitate to obtain clear and transparent juice with low chroma. Fourth, evaporate sugarcane juice. That is, sugarcane juice is evaporated and concentrated. Although this step is not critical, it can be used for the second time. For example, it is used for the next heating, and it is led out for other equipment. 5. Crystallization of sugarcane juice. Sugarcane juice is evaporated and concentrated into syrup, and then a series of treatments, such as concentration, crystallization, re-concentration, recrystallization, crystal aid, centrifugation, separation, drying and so on, can get the finished white sugar.
