Working principle of experimental vacuum spray dryer

      It means that the material will be dried in a vacuum environment, so that the material will not be polluted by outside air. Of course, the vacuum spray dryer can also be upgraded to a closed spray dryer and a low temperature spray dryer. Of course, its speed can also be adjusted according to actual needs. In addition, the vacuum spray dryer can also be used in conjunction with different cloth devices, which can meet the drying treatment of different forms of materials, such as the drying of liquids, extracts, powders and other materials.

Working principle of vacuum spray dryer

      Spray drying device The spray dryer is a dryer used to process solutions, suspensions or slurry materials. The spray dryer uses the spray method to make the material into mist droplets and dispersed in the hot air stream. The material and the hot air are in contact with each other in a co-current, counter-current or mixed-flow manner, so that the water evaporates quickly and achieves the purpose of drying. Using this drying method, chemical unit operations such as concentration or filtration can be omitted, and granular products of 30 to 50up can be obtained in a very short drying time. Usually, the drying time is 5-30s. The spray dryer is suitable for spray dryers with high heat sensitivity. Only when the production capacity is greater than 100kg (water)/h
