微波炉加热圆柱形食物的温度分布

微波热效应的发现带来了厨房革命,微波能因其作用的整体性特点成为高效热源,微波炉成为食品的重要加工设备。但是微波加热的食物产品常因受热不匀出现质量问题,并导致能源和物质资源的浪费。为了找出微波能作用饼形食物形成的温度分布规律,介绍了微波加热的原理和特性,分析了微波能在食物中的作用过程,由能量守恒及转化定律,推导出了圆柱形食物的温度分布计算式,并用MATLAB软件进行数值计算得到其分布规律。

Temperature Distribution on Cylindrical Shaped Food during Microwave Heating

Microwave heating effect brings the revolution of the cooking, microwave ovens heat food volumetrically by electromagnetic radiation, so microwave energy become an efficient source of heating, microwave oven is the main role in food processing equipment. But microwave heating food products because of uneven heat often appear quality problems, and lead to the waste of energy and material resources. In order to find the temperature distribution regular pattern of cylindrical shaped food heated by microwave, introduced the principle of microwave heating and features of microwave, analyzed the heat transfer law of food, by the law of conservation and transformation of energy, the formula for food temperature distribution at different time and different radial were deduced, use MATLAB software to carry out the temperature distribution regular pattern.
