摘要:

实验研究了鲤鱼在静磁场中的冷冻过程,所有样本质量为600~800g,腹部最厚处的尺寸为46~ 52mm。冷冻过程在速冻冷库中进行,冷冻方式为鼓风式冷冻,冷库温度设定为-35℃。施加的磁场强度分别为0G、3.6G、7.2G、10.8G,测量并连续记录冷冻过程中样本表面和热中心的温度。实验结果表明,磁场对鲤鱼不同冷冻阶段的影响规律不同。磁场对鲤鱼冷却阶段的影响较小,对相变阶段有着明显的促进作用,对冻结阶段有延缓作用。

Abstract:

Carp frozen process in static magnetic field was experimentally investigated. The test samples were between 600~800g and the maximum thicknesses were between 46~52mm. All frozen processes were performed in an airblast quickfreezer, where the temperature was set -35℃. Magnetic field intensity was respectively 0G/3.6G/7.2G/10.8G. The surface and thermal centre temperatures were measured and recorded continuously in the whole frozen processes. The results indicated that the rule magnetic influencing frozen rate varied at different frozen stages. Magnetic field had little influence on cooling period, while, it held obvious promotion at phase change stage and delayed the freezing period.

Key words: quick-freeze, temperature drop rate, magnetic field intensity, thermal centre, temperature-time curve
