餐厨垃圾微波干燥实验装置

An Experimental Microwave Dryer for Disposing Food Wastes

为节能、环保地达到餐厨垃圾的处理目标,基于餐厨垃圾的特点,利用微波加热技术设计了一种餐厨垃圾微波干燥装置,并进行了餐厨垃圾的微波干燥实验。结果表明,该装置操作简单,便于控制,可以满足餐厨垃圾的处理要求;对含水率很高的餐厨垃圾进行微波干燥处理,宜采用前期微波通风与后期微波真空的组合干燥方式。研究结论可为餐厨垃圾微波处理设备的设计提供参考依据。

The pollulion caused by food residue is increasingly serious, which has constituted a great threat to both environment and human heahh. Therefore, the dispose of food wastes in an energy-saving and environmentally friendly way, and turning the wastes into a useful resource is a problem confronting the environment protection workers. In this paper, based on the microwave heating technology and the characteristics of food wastes, an experimental mierowave dryer for disposing food wastes was proposed. The experimental results show that the proposed device which is easy to operate and control can meet the test requirement of food residue proeessing. For disposing the food wastes of high water content, a combination of the drying process consisting of ventilation microwave in the initial drying phase and vacuum microwave in the final drying stage should be used. This paper is of reference and help for the design of microwave food wastes processing equipment.
