摘要

利用所搭建的小型动态制冰装置制取冰浆，实验探讨了结晶时间、载冷剂温度、添加剂种类与浓度、刮削速度等因素对冰浆动态制备过程的影响，研究中基于热平衡方法测得结晶过程不同时刻的含冰率，对所制取的冰浆进行显微拍照，并基于图像处理获取冰晶尺寸的当量直径。实验结果表明，在动态结晶过程的测试时间内，制冰溶液的降温速率受外界条件影响较小，但添加剂种类与浓度对制冰溶液的相变结晶温度以及过冷度影响较大；制冰溶液的含冰率与冰晶尺寸均随时间的增加而增大，其中载冷剂温度、添加剂种类与浓度对溶液含冰率影响较大，而对冰晶尺寸影响最大的因素是刮削速度与添加剂浓度；当结晶过程进行到30 min时溶液的含冰率均达到25%，冰晶尺寸均能达到0.12 mm左右。

Abstract

The ice slurry was prepared by using the small scale ice making machine. The effects of crystallization time

second refrigerant temperature

additive type and concentration

and scraping speed on the dynamic generation process of the ice slurry were investigated. The heat balance method was used in the study. The ice packing factor at different times of the crystallization process was microscopically photographed

and the equivalent diameter of the ice crystal size was obtained based on image processing. The experimental results show that the cooling rate of the ice-making solution is less affected by external conditions during the test time of the dynamic crystallization process

but the type and concentration of the additive have a great influence on the phase change crystallization temperature and supercooling degree of the ice-making solution. The ice packing factor and ice crystal size of the solution increase with time. The temperature of the brine

the type and concentration of the additive have a great influence on the ice content of the solution

and the factors that have the greatest influence on the ice crystal size are the scraping speed and the additive concentration. When the crystallization process is carried out for 30 min

the ice content of the solution reaches 25%

and the ice crystal size can reach about 0.12 mm.
