Heat Transfer of Spray Dryer Extraction Machine Based On Parametric Design Modeling

Drying is a work process that requires intense energy, because of the latent heat in the air as the drying medium. This paper presents a model of the Spray Dryer Extraction Machine whose principle is drying using a vacuum model. The extraction process in this machine is located in a holding tube equipped with a water jacket with a lid that is connected directly to the vacuum pipe above. The heat source comes from a gas stove with a working temperature between 70-150 degrees Celsius. The computer simulation method used is to analyze the Blower Frequency Rotation and Heat Transfer Spray Dryer Extraction Machine. Starting from parametric 3D model design, geometric simplification, and wizard simulation. The results show that the simulation of the rotation and frequency of the blower with 5 times the amplitude (increment) produces vibrations when there is a centrifugal force. With an LHV value of 46MJ/kg from the burner, it has a Heat Flux of 56,964,402 W/m^2. A probe has been carried out on the tube nodes to determine the value of the heat flux at the desired node points. Node 1 has a heat flux value of 56,037,832 W/m^2 with a temperature of 522,781 K. Node 2 has a heat flux value of 56,964,402 W/m^2 with a temperature of 514,902 K. Node 3 has a heat flux value of 26,108,422 W/m^2 with a temperature of 506,104 K. Node 4 has a heat flux value of 387,335 W/m
