sokerivalmistus

Sokerivalmistus, also known as sugar refining, is the process of purifying sugar from raw sugar, which is typically obtained from sugarcane or sugar beets. The primary goal of this process is to remove impurities such as molasses, color, and other non-sugary substances, resulting in a product that is white, crystalline, and suitable for consumption or industrial use.

The refining process begins with the dissolution of raw sugar in hot water, forming a syrup. This syrup is then filtered to remove impurities and impurities are removed by a series of purification steps, including carbonation, clarification, and crystallization. Carbonation involves passing carbon dioxide through the syrup to remove color and impurities, while clarification uses chemicals like lime or phosphoric acid to remove remaining impurities. Finally, crystallization is achieved by cooling the syrup, which causes sugar crystals to form. These crystals are then separated from the remaining liquid (mother liquor) and dried to produce refined sugar.

Sokerivalmistus is a crucial step in the sugar industry, as it enhances the quality and purity of sugar, making it more suitable for various applications, including food and beverage production, pharmaceuticals, and industrial uses. The process also helps in reducing the environmental impact of sugar production by recovering and utilizing by-products like molasses, which can be fermented to produce ethanol or other valuable products.
