太阳能荫房制干实验装置的设计研究

The Design Research of the Experimental Facility Using in the Making Dry in the Dry Room Using the Solar Energy

葡萄干产业中,为保持其独特的口味,葡萄干燥的过程不能见阳光,为了提高生产效率,传统的利用自然通风进行葡萄制干的荫房已不能满足要求。现设计采用辅助吸热体的太阳能荫房制干实验装置替代传统的制干装置,充分利用当地丰富的太阳能资源。此装置可使被干燥物料不见阳光,采用黑蜂窝孔板送风的气流设计,做到了有效利用集热面积,具有静压排湿,热惯量较大等特点,相对于传统方法还可缩短制干周期,适用于更广泛的地区。本装置不仅适用于葡萄制干,如略加改动也适用于其他可见阳光的物料的制干。

In raisin industry, the process of drying grape stem can not be under sunshine for maintaining its unique taste. To improve production efficiency, the traditional way using natural ventilation system for drying grape stem has been unable to meet the demand. Currently, it is designed with the assistance of solar energy absorber to replace the traditional system stem experimental device, which completely uses local rich solar energy resources. This device enables dry materials without sunlight. The design of airflow through black honeycomb-cell plate ensures an effective use of thermal collection area with features on High static pressure dehumidifying and greater thermal inertia. Comparing with the traditional method, the design can shorten the cycle of the system drying and apply to a wider area. The device can be applied to not only the dry grapes system, but also the dry system of other visible material by some little changes.
