| Abstract | ||||
| Spray drying is one of the key methods that dry liquid into powder. It is used in different fields such as the food, pharmaceutical, chemicals, and cosmetics industries. Spray drying is a method used to produce dry powder from liquids with different viscosities, by using hot gas for rapid drying. The core of this machine is the atomizer. Originally, drying techniques were based on rotary discs and single fluid high pressure vortex nozzles. Spray dryer dries the product more rapidly. The spray dryer process starts with atomization of a liquid to separate it into spray with controlled droplet size. These droplets are then exposed to a hot gas in the drying chamber passing through pipes to the powder collecting tank. Furthermore, spray drying offers multiple possibilities that no other drying technology can claim. It is characterized by the speed of the process and updated technologies such as PLC screens. In addition, spray drying offers unique opportunities in particle size engineering. Therefore, this paper focuses on the spray drying method using the spray dryer machine. The paper presents a mathematical model for the spray dryer using MATLAB, along with computational fluid dynamics simulation using ANSYS. | ||||
