In our previous study, it was noticed that the combined freezing, soaking and centrifugal desalination (FSCD) process is unsuitable to be applied in summer, because very little pure ice can be produced when the temperature of raw seawater used as soaking liquid reaches 27 °C. Therefore, two main efforts on the process optimization were made in this paper. One is that low-temperature seawater served as soaking liquid in all the experiments. In real industrial practice, the low-temperature soaking liquid can be obtained through melting pure ice products or recovering cold energy from cold concentrated brine. The effects of centrifugal parameters and soaking time on salt removal efficiency and ice yield rate were investigated. Second, the gravity-induced method was combined to form freezing, soaking, gravity-induced and centrifugal desalination (FSGCD) processes for further improvement of the salt removal efficiency. The influence of melting time of gravity-induced process was studied by keeping the samples ambient with an air temperature of 30 °C. Finally, the performance among different processes was compared. Results showed that the salt removal efficiency of the FSGCD process can reach up to 97.03%. The study is helpful to improve the process performance of soaking treatment in summer application.

在我们之前的研究中，注意到联合冷冻、浸泡和离心脱盐 (FSCD) 工艺不适合在夏季应用，因为用作浸泡液的原海水温度达到 27° 时，只能产生很少的纯冰C。因此，本文在工艺优化方面做了两个主要努力。一是所有实验均采用低温海水作为浸泡液。在实际工业实践中，可以通过融化纯冰制品或从冷浓盐水中回收冷能来获得低温浸泡液。考察了离心参数和浸泡时间对脱盐效率和产冰率的影响。二是结合重力诱导法，形成冷冻、浸泡、重力诱导和离心脱盐 (FSGCD) 工艺，以进一步提高除盐效率。通过将样品保持在空气温度为 30 °C 的环境中，研究了重力诱导过程的熔化时间的影响。最后，比较了不同进程之间的性能。结果表明，FSGCD工艺的脱盐效率可达97.03%。该研究有助于提高夏季应用浸泡处理的工艺性能。结果表明，FSGCD工艺的脱盐效率可达97.03%。该研究有助于提高夏季应用浸泡处理的工艺性能。结果表明，FSGCD工艺的脱盐效率可达97.03%。该研究有助于提高夏季应用浸泡处理的工艺性能。
