【摘要】 针对采用过冷水法动态制冰出现冰堵的问题，提出了一种配有模块化刮片式过冷解除装置的冰浆制取系统，试验研究了NaCl添加剂浓度、制冰溶液流量、二次冷媒起始温度和过冷解除装置转速对制冷性能的影响。结果表明，配套刮片式过冷解除方案的制冰系统在NaCl溶液浓度不低于7%时可实现稳定、持续产出冰浆；保持NaCl溶液浓度7%，制冰溶液流量、二次冷媒起始温度和刮片转速对含冰率和持续制冰时间均会产生显著影响，冰浆含冰率最高可达21.6%，制冰效率在1.40～3.48 kg/h范围内，持续制取可流动冰浆的时间稳定在40 min以上；与螺旋叶片式过冷解除装置相比，刮片式过冷解除装置有效解决了过冷却器的冰堵现象，持续制冰时间增长了4.6～72.7倍。研究可为制冰系统持续制造冰浆提供保障。更多还原

【Abstract】 In view of the problem that ice blockage is prone to occur when using supercooled water method make dynamic ice,propose a set of ice slurry production experimental device equipped with blades-type super-cooling releasing device.The test performance shows that the ice making system with blades-type super-cooling releasing solution can stably and continuous work when the concentration of NaCl solution is not less than 7%.The concentration of NaCl solution is maintained at 7%,change other working conditions such as the flow rate of the ice-making solution, the initial temperature of the secondary refrigerant,the speed of the scraper, the maximum ice content of the ice slurry reach 21.6%.The ice slurry output of this ice slurry system can reach 1.40 ～3.48 kg/h.The time for continuous production of flowable ice slurry can be stabilized over 40 min.Compared with the spiral-blade-type super-cooling releasing device,the blades-type super-cooling releasing device effectively solves the ice blockage phenomenon of the super-cooler,and the continuous ice-making time increases by 4.6 to 72.7 times.The blades-type super-cooling releasing device can provide guarantee for the continuous production of ice slurry in the ice making system.更多还原
