Development of low temperature and high humid storagesystem for fresh produce by using nano-sized mist

为开发低温高湿保鲜保鲜系统，采用纳米微雾进行了模拟和实验研究；1)模拟安装纳米级雾状加湿器的储存库内温度、湿度和风速的变化；2)光催化贮藏中微生物灭活；3)静电沉淀法去除贮存中的微生物和粉尘；4)高湿贮藏保鲜农产品蒸腾作用的控制。结果，获得了温度、湿度和风速的详细分布，并指出了在储存库中进行消毒和静电沉淀的可能性。此外，纳米雾比大尺寸雾更有效地控制了新鲜农产品的失重。

To develop a low temperature and high humid storage system for fresh produce by using nano-size mist, a simulation and experiments as follows were conducted; 1) simulation of changes in temperature, humidity and air velocity in a storage equipped with nano-size mist humidifier; 2) inactivation of microorganisms in the storage by photo catalyst; 3) removal of microorganism and dust in the storage by electrostatic precipitation; 4)control of transpiration of fresh produce stored in the high humid storage. As a result, a detailed distribution of temperature, humidity and air velocity was obtained and a possibility of disinfection and electrostatic precipitation in the storage was indicated. In addition a weight loss of fresh produce was controlled by the nano-size mist more efficiently than a larger size mist.
