摘要
喷雾干燥技术被广泛应用在许多工业生产领域中,本文从工艺、机理、产品的质量和节能等几个方面对喷雾干燥在生物质资源加工利用中的发展状况进行了概述,发现研究过程中尚存在着一些问题,如由于高进气温度使产品质量下降;在干燥室或工艺管中发生产品粘壁;系统能效低及生物制品中活性物质被破坏等,亟需在工艺及设备等方面改进和提高,因此很有必要对喷雾干燥技术进行更深入的研究。
Spray drying technology was found to be widely used in many industries. This paper summarized the developments of spray drying of biomass materails in terms of processing, mechanism, quality of product and economically utilization of energy etc. The review showed that there were some problems which needed to be improved in term of process and equipment. For exampies, the product quality was degraded due to high inlet temperature, wall deposits existed in drying chamber or process pipes, energy efficency was low and active contents in the biomass were damaged, etc. Therefore the further investigation in spray drying technology was necessary.
