制糖工业的主要原料是甘蔗和甜菜。炎热地区适宜栽培甘蔗,甘蔗糖制造工业就比较发达,如我国台湾、广东等地。而寒冷地区适宜生成甜菜,甜菜糖制造工业亦就旺盛,如苏联、捷克斯洛伐克、德国等。目前,我国的制糖工业以甘蔗糖为主。在制造的产品中,又因原料的各异,制造程序的不同,结晶颗粒的大小,色泽的深浅,具有种种的名称。普通常见的是白糖、红糖和冰糖。白糖,就是普通的粗制糖。一般是经过甘蔗压榨、蔗汁澄清、压滤、蒸发浓缩後,得到浓厚的糖浆。浓厚的糖浆再煮沸精炼到一定浓度(饱和点),晶体即行结出。煎糖而得的蔗糖结晶,和糖蜜混合在一起,叫作糖膏。使用离心机把它们分出,所得到的结 The main raw materials for the sugar industry are sugar cane and sugar beets. Hot areas are suitable for sugarcane cultivation, and the cane sugar manufacturing industry is relatively developed, such as Taiwan and Guangdong in China. In the cold regions, sugar beet production is suitable, and the beet sugar manufacturing industry is also booming, such as the Soviet Union, Czechoslovakia, and Germany. At present, China’s sugar industry is dominated by cane sugar. In the manufactured products, because of the different raw materials, different manufacturing processes, the size of the crystal grains, the depth of color, it has various names. Common common are white sugar, brown sugar and rock sugar. White sugar is ordinary crude sugar. Generally, after the sugarcane crushing, sugarcane juice clarification, pressure filtration, evaporation and concentration, a thick syrup is obtained. The thick syrup is then boiled and refined to a certain concentration (saturation point) and the crystals are ready to go. The sucrose crystals derived from frying sugar and mixed with molasses are called confectionery. Using a centrifuge to separate them, the resulting knot
