摘要： The present invention relates to a process for producing sugar from beets, comprising the steps of: (a) macerating beets or pieces thereof; (b) mechanically separating juice from the macerated beets; and (c) membrane filtering the separated juice, producing a retentate and a permeate. The mechanical extraction of juice can be done on a moving porous vacuum filtration belt with countercurrent flow of macerated beets and water. The pH of the vacuum extracted juice can be adjusted to at least about 7 by addition of sodium hydroxide. This process does not use conventional beet diffusion. No lime and no carbon dioxide are required to be contacted with the juice or the permeate in this process.

摘要： A process for treating impure cane-derived sugar juice comprises subjecting, in a clarification stage, the juice to microfiltration/ultrafiltration to decrease the levels of suspended solids, organic non-sugar impurities and/or colour therein. The resultant clarified sugar juice is sequentially passed through an ion exchange stage by bringing the juice into contact with a strong acid cation ion exchange resin in the hydrogen form, and thereafter into contact with an anion ion exchange resin in the hydroxide form. A purified sugar solution is withdrawn from the ion exchange stage, and concentrated to produce a syrup. The syrup is subjected to primary crystallization in a primary crystallization stage, to produce refined white sugar and primary mother liquor. The primary mother liquor is subjected to secondary crystallization in a secondary crystallization stage, to produce impure crystallized sugar and white strap molasses.
摘要翻译：用于处理不纯甘蔗来源的糖汁的方法包括在澄清阶段使果汁进行微滤/超滤，以降低其中的悬浮固体，有机非糖杂质和/或颜色的水平。通过使果汁与氢形式的强酸性阳离子离子交换树脂接触，然后与氢氧化物形式的阴离子交换树脂接触，将所得澄清的糖汁依次通过离子交换阶段。将纯化的糖溶液从离子交换阶段取出，并浓缩以产生糖浆。将糖浆在初级结晶阶段进行一次结晶，以生产精制白糖和初级母液。初级母液在二次结晶阶段进行二次结晶，产生不纯的结晶糖和白色带状糖蜜。

摘要： Methods for the purification of sugar solutions using hydrolyzed polyacrylamides as flocculants are herein described. The hydrolyzed polyacrylamides are prepared from emulsion or microemulson polymerization of acrylamide monomer, and subsequently hydrolyzed to a degree of hydrolysis of about 10 to about 50 mole %. The hydrolyzed polyacrylamides have a molecular weight of at least about 10,000,000.
