摘要： An example method for refining lactose may include washing lactose crystals in a lactose stream in an upstream wash stream including an upstream recirculating wash medium. Washed lactose crystals may be sieved from the upstream recirculating wash medium. The upstream recirculating wash medium may be recirculated back to the upstream wash stream. The washed lactose crystals may be discharged to a downstream wash stream comprising a downstream recirculating wash medium. An example system may include a plurality of refining stages. At least one refining stage may include a washing tank including a lactose crystal inlet and a crystal slurry outlet. The refining stage may include a pump to recirculate a wash stream from the crystal slurry outlet back to the washing tank at a predetermined flow rate. The refining stage includes a screen to separate washed lactose crystals from the wash stream.

摘要： A system for drying a wet lactose product stream includes a disperser configured to disperse agglomerated lactose particulates in a wet lactose stream into a dispersed wet lactose stream. A back-mixed partial drying zone is configured to at least partially dry the dispersed wet lactose stream by recirculating a partially dried lactose stream with the dispersed wet lactose stream. A plug-flow secondary drying zone is configured to dry the partially dried lactose stream to generate a substantially dried lactose stream.
摘要翻译：用于干燥湿乳糖产品流的系统包括分散器，其被配置成将凝聚的乳糖微粒分散在湿乳糖流中分散到分散的湿乳糖流中。将回混的部分干燥区构造成通过用分散的湿乳糖物流再循环部分干燥的乳糖物流来至少部分地干燥分散的湿乳糖物流。活塞流二次干燥区构造成干燥部分干燥的乳糖物流以产生基本上干燥的乳糖物流。

摘要： Systems and methods for processing a high-lactose aqueous fluid (HLAF)(3), such as permeate from ultrafiltration of whey fluid, are described. The preferred process includes concentrating HLAF (3) containing from about 1 to about 35% solids, wherein at least 50% of the solids are lactose, to form a concentrated HLAF (3) containing from about 45 to about 65% solids; further concentrating the HLAF (3) to form a highly concentrated HLAF (3) containing from about 70 to about 80% solids; cooling the highly concentrated HLAF (3) with a gaseous fluid to create a cooling, concentrating, crystallizing cascade to further concentrate the HLAF (3) to form a partially crystallized HLAF (3) containing from about 78 to about 88% solids; and drying the partially crystallized HLAF (3) in an air-lift dryer (24) to form a product rich in crystalling alpha-lactose monohydrate. An air-lift dryer (24) having diverging sidewalls (32) and methods of using same are also disclosed.
