摘要
随着食品保鲜需求的不断增长,冷库冷冻冷藏技术的优化及发展变得愈发重要。本研究评估了高压静电场辅助解冻在冷库中的应用效果,监测了冷库内部三层货架区域的各项参数,包括温度、湿度、风速变化以及货架电压分布。以冷冻猪肉作为实验样品,观察解冻速率、温度均匀性和解冻效果。研究结果表明,冷库三层货架的温度分布、相对湿度以及温度均匀度无显著性差异,但中层货架的电压最大,能够有效加快冷冻猪肉解冻速率,相比于电压微弱的下层,中层平均升温速率比下层提高78.7%左右,并保持良好的肉类解冻品质。本实验研究结果可为高压静电场技术在冷库食品解冻、贮藏保鲜等领域发展提供参考。
With the increasing demand for food preservation,the optimization and development of cold storage refrigeration technology becomes more and more important.In this study,the application effect of the high voltage electrostatic field assisted thawing in cold storage,and monitored various parameters in the three-layer shelf area of the cold storage,including temperature,humidity,wind speed and shelf voltage distribution.Frozen pork was selected as the experimental sample to observe the thawing rate,temperature uniformity and thawing effect.The results indicated that there were no significant differences in the temperature distribution,relative humidity,and temperature uniformity among the three shelves in the cold storage.However,it was observed that the middle shelf exhibited the highest voltage,which could effectively improve and accelerate the thawing rate of frozen pork.Compared with the lower layer with weak voltage,the average heating rate of the middle layer was about 78.7%higher than that of the lower layer,and good meat thawing quality was maintained.The results of this experiment provide references for further research on the application of high voltage electrostatic field technology in food cold storage thawing and fresh-keeping.
