Spray dryer process has been widely used in food powder production. The spray dryer process is a process which is used to transform the feed from a liquid state into a dried powder by spraying the feed into a hot drying medium. The objective of the spray drying process is to produce a product of a desired quality at a minimum cost, with maximum throughput and sustain the desired dried product quality regardless of the disturbances in the drying operation and variations in feed supply. Appliance of automatic control system offers an opportunity to improve the dryer operations and its efficiency. The spray dryer chamber uses the outlet air leaving the spray dryer chamber to describe the drying condition and uses it as a control variable in a feedback control. The moisture content is controlled indirectly by maintaining a specific outlet air temperature by varying either the feed flow into the dryer or the inlet drying air temperature. The microcontroller with PID controller giving better spray dryer chamber process more stable based temperature control hot drying air leaving the chamber after 2000ms. © 2016 IEEE.
