液空速冻干燥设备

目前，一般采用液氮进行高档海鲜、水果深冷速冻干燥。液氮是液态的氮气，液体温度为-196℃，是惰性的，无色，无臭，无腐蚀性，不可燃的，一般来自炼钢厂、煤化工装置配套的空分装置。海鲜一般要求在沿海就近处理，能够保持海鲜的品质与口感。采用液氮进行深冷速冻，需要液氮槽车进行长距离运输与配送；液氮使用后的低温气体无法回收利用，直接放空，造成冷量的损失与资源的浪费。同时，液氮的使用需要下游用户配置独立的液氮储罐进行储存，液氮在运输与储存过程中，如果发生泄露，容易造成局部缺氧窒息环境，对生命财产造成极大危害。

液空，是液态的空气，是无色无味，安全可靠，液体温度为-194℃，本公司开发的移动式液空生产设备直接生产超低温液空产品，代替液氮进行海鲜、水果深冷速冻干燥，克服了液氮的缺点；用液空代替液氮的使用，不仅降低海鲜、水果深冷速冻的成本，而且避免液氮的泄漏对生命造成危害和对财产造成损失。

At present, liquid nitrogen is generally used for deep-freezing and quick-freezing drying of high-grade seafood and fruits. Liquid nitrogen is liquid nitrogen, the liquid temperature is -196℃, is inert, colorless, odorless, non-corrosive, non-combustible, generally from steel mills, coal chemical equipment supporting the air separation device. Seafood is generally required to be processed near the coast to maintain the quality and taste of seafood. Using liquid nitrogen for cryogenic quick freezing requires liquid nitrogen tank truck for long-distance transportation and distribution; The low temperature gas after the use of liquid nitrogen can not be recycled, and it is directly vented, resulting in the loss of cold capacity and waste of resources. At the same time, the use of liquid nitrogen requires downstream users to configure independent liquid nitrogen storage tanks for storage, liquid nitrogen in the process of transportation and storage, if there is a leak, it is easy to cause local anoxic asphyxia environment, causing great harm to life and property.
Liquid air, is the liquid air, is colorless, tasteless, safe and reliable, liquid temperature of -194℃, the company developed mobile liquid air production equipment directly produce ultra-low temperature liquid air products, instead of liquid nitrogen for seafood, fruit cryogenic quick freezing and drying, to overcome the shortcomings of liquid nitrogen; The use of liquid air instead of liquid nitrogen not only reduces the cost of deep-freezing and quick-freezing seafood and fruits, but also avoids the leakage of liquid nitrogen causing harm to life and damage to property.
