How to extract white sugar from sugarcane
At present, sugarcane white sugar can be divided into sulfide sugar and carbonized sugar according to the different sugar making processes.

Carbonated sugar has long shelf life, good quality and low price.

The content of glucosinolate is relatively high. At present, most sugar factories in China produce glucosinolate.

(1) Sulfite clarification technology is a typical method for cleaning and decoloring sugarcane juice and syrup in sugar production industry. Because of this method,

It has the characteristics of less equipment, simple technological process and convenient management, so this clarification technology has been widely used in China's sugar industry.

Universal application.

However, compared with carbonation clarification technology, sulfite clarification technology relies on calcium phosphate and calcium sulfite for absorption.

Impurities are attached to sugarcane juice, and the sulfur bleaching of syrup is based on the principle of reduction reaction, so the quality of white sugar produced by sulfite sugar factory is low.

Often bad, it will turn yellow after a long time.

On the one hand, the sucrose content of white sugar produced by sulfite sugar factory may meet the requirements of physical and chemical indexes of products, but it is only an individual non-sugar index.

Can not meet the requirements, which is the reason why the quality of white sugar in sulfite sugar factory is not good.

Therefore, the color value of the produced white sugar can reach about 150IU, which is relatively high.

Even more than 200IU.

Obviously, in order to improve the quality of sulfite sugar and white sugar, the color value of the products must be reduced.

(2) Characteristics of carbonized sugar-carbonized sugar: The method of clarifying sugarcane juice with lime and carbon dioxide is called carbonization method, which is used.

The sugar produced is called carbonized sugar, also called carbon (acid) sugar.

The production of sugar by carbonic acid method removes more non-sugar substances than by sulfurous acid method.

The finished sugar has high purity, low color value and low sulfur content, and can be stored for a long time without discoloration.

However, the carbonation process is complicated and requires mechanical equipment.

The more equipment, the more lime and carbon dioxide are consumed, so the higher the production cost.
