流动湿空气解冻装置设计

本文作者所设计的流动湿空气解冻装置采用双叶轮风机，工作时自动定时换向，并在解冻室两端设置可调式导风板的供风系统；以喷蒸汽加热、加湿，辅之以淋水和挡雾板的方法实现空气的调温、调湿和净化；装置的工况采用微机控制。按该方案制成的样机在生产中试用取得良好的效果。

DESIGING CONSIDERATIONS OF HUMIDIFIED AIR-BLAST THAWING EQUIPMENT

In order to optimize the designing scheme for a humidified air-blast thawing equipment,its principle and thawing technology of various kinds of food should be considered. A fan with dual-vane wheel which would automatically reverse at regular intervals and the adjustable deflectors at the ends of thawing chamber are used in the air supply system. Besides the methods of spreying steam, spreying water and setting mistguard are adopted for heating, humidifying and purging the air passing through the chamber, and the working conditions are controlled by the microcomputer system in the equipment designed by present authors. The sample has been operated successfully in a meat packing plant.
