Sugar cane juice concentration via evaporation is the traditional method, though the downside in this technique is the product loss due to sucrose inversion. Gas hydrate separation is an emerging technology applied in desalination, carbon capture, and in this study, for concentrating fruit juice by trapping the water in the form of crystalline cages. A 750 cm³ hydrate reactor was used for hydrate formation experiments to concentrate the sugar cane juice, with a sampling of the concentrate to determine the final solids content. Hydrate formation experiments showed the successful concentration of a 0.12 mass fraction feed to approximately 0.56 mass fraction using four batchwise concentration stages. A comparison of the energy usage between the evaporation train as used in sugar factories and a single batch hydrate formation stage, to concentrate a 0.12 mass fraction feed to 0.30 mass fraction showed an energy reduction of approximately 20% for the hydrate method.

通过二氧化碳气体水合物的形成来浓缩甘蔗汁

通过蒸发浓缩甘蔗汁是传统方法，尽管该技术的缺点是由于蔗糖倒置而导致的产品损失。天然气水合物的分离是一种用于脱盐，碳捕集的新兴技术，在本研究中，该技术通过将水以结晶笼的形式捕集来浓缩果汁。750厘米³水合物反应器用于水合物形成实验以浓缩甘蔗汁，并对该浓缩物进行取样以确定最终固体含量。水合物形成实验表明，使用四个分批浓缩阶段，可将0.12质量分数的进料成功浓缩至约0.56质量分数。将制糖厂使用的蒸发流程与单批水合物形成阶段（将0.12质量分数的进料浓缩至0.30质量分数）之间的能量使用进行比较，发现水合物方法的能耗降低了约20％。
