冷冻干燥过程的热经济学分析

Thermoeconomical analysis of freeze-drying process

文章运用热经济学原理对冷冻干燥过程中的设备投资和能源消耗建立了对应的估算模型。以单位产量年度化成本为分析对象 ,对影响其成本的几个重要参数 (湿物料的初始温度、干燥室压力和物料厚度 )进行了探讨 ,并进行了优化 ,得到了一些重要的结论 ,为食品冷冻干燥的生产和投资提供了理论依据。

This paper analyzes the energy consumption and investment of the facilities of the freeze-drying process and the corresponding models are made with the principle of the thermoeconomics.Some conclusions are made after the research and optimization of the important parameters,namely the original temperature of wet material,the pressure in the drying chamber and the thickness of the material. They can theoretically support the production and investment of freeze-drying process for food
