Dryers play a very important role in the processing of food, chemical and pharmaceutical products. The drying performance depends on various factors such as the type of dryer, the temperature and speed of the incoming air to the dryer, the size and amount of incoming materials, and the time the materials stay in the chamber. For this reason, it is necessary to carry out specific studies in the field of drying products. On the other hand, designing, manufacturing, and equipping dryers with sensors to measure various characteristics is a costly process, and in recent research, numerical and simulation methods have been used to analyze dryers. Therefore, in this article, the characteristics affecting the drying process in a cross-flow fluidized bed dryer with a tray were investigated by CFD method. For this purpose, the mass flow rate effect of materials in 3 levels is 2.76, 5.76 and 8.1 kg/h, the velocity of incoming hot air in 4 levels is 2.5, 3, 4 and 5 m/s and hot air temperatures in 4 levels of 50, 60, 70 and 80 degrees Celsius on the speed and pressure inside the chamber was checked by ANSYS fluent 18 software. The results showed that increasing the temperature caused an increase in the air pressure and speed inside the chamber and in the bed. Increasing the feed flow decreased the pressure and velocity.
