Abstract: A pulse inverse blow filter bag dust collector is a dust removal device where compressed airflow is instantaneously switched through an electromagnetic pulse valve and then sprayed into a filter bag through an injection pipe, and finally the resulting counterblast causes the filter bag to swell up, thus achieving dust removal. The dust collector can allow continuous, complete dust removal. As a time saving and efficient tool, it has recently been applied in various areas of spray drying production such as dairy products, medical and healthcare products and further processed corn and soybean products. However, there are some problems in its applications. This paper describes the design and application of a pulse inverse blow filter bag dust collector in MGYP01-500 type vertical pressure spray drying system for milk powder production. Besides, some attention points for its application are included.
