摘　　要：本文通过对抗菌的纳米精油胶囊蓄冷节能冰鲜技术进行研究,设计一种以代替超市现在传统的厚冰保鲜的装置,降低水产保鲜成本。装置选用8%浓度的NaCl溶液作为相变蓄冷材料,乙二醇作为载冷剂,为装置提供冷量并存储,并添加肉桂纳米精油胶囊,以达到保鲜的效果。结果表明:8%浓度的NaCl溶液作为蓄冷材料提供的冷量足以使得水产的中心温度在14h内都保持2℃以下,与传统铺冰方式相比具有更好的冷藏效果。通过保鲜抗菌实验测试,肉桂纳米精油胶囊能有效提高装置对冰鲜产品的保鲜效果并减小失水率。本装置运行一年最多可节省成本646.05元,具有成本低廉、易于推广的优点。Based on ice fresh cold storage and energy saving technology of antibacterial nano essential oil capsule,a device is designed to replace the traditional ice preservation in supermarkets and reduce the cost of aquatic preservation.In this paper,8%NaCl solution is selected as phase change cold storage material and ethylene glycol as secondary refrigerant is prepared to provide cooling capacity for the unit and store it,and cinnamon nano essential oil capsules are added to achieve the effect of fresh-keeping.Results show that the cooling capacity provided by 8%NaCl solution as cold storage material is enough to keep the central temperature of aquatic products below 2℃within 14 hours,which has better cold storage effect than the traditional ice laying method.Through the fresh-keeping and antibacterial experiment,the nano essential oil capsules prepared by cinnamon essential oil can effectively improve the fresh-keeping effect of the device on ice fresh products and reduce the water loss rate.The device can save 646.05 yuan in cost after one year of operation,and has the advantages of low cost and easy popularization.
