喷雾干燥器是热风加热干燥装置的一种,它具有以下一些基本的特点。 (1)由于制品的干燥温度,不超过其湿球温度,因而制品较难受热的影响,即使是耐热性差的物质也可进行干燥。 (2)根据喷雾机理,制品在表面张力作用下形成球状颗粒,干燥制品的流动性好。 (3)因表面张力的作用而产生球状颗粒的物质特性促使干燥向制品颗粒内部发展,保持一定的蒸 Spray dryer is a hot air drying device, it has some of the following basic features. (1) Since the drying temperature of the product does not exceed the wet bulb temperature, the product is hardly affected by the heat, and even the poorly heat-resistant material can be dried. (2) According to the spray mechanism, the product forms spherical particles under the surface tension, and the fluidity of the dried product is good. (3) due to the role of surface tension of the material properties of spherical particles to promote drying to the internal development of the product particles, to maintain a certain degree of steam
