Potassium nitrate is an inorganic salt with a chemical formula of KNO3. It is a natural source of nitrate and has been used as a constituent for several different purposes, including food preservatives, fertilizers, , rocket propellants and fireworks. Potassium nitrate is obtained through a process that mixes sodium nitrate, derived and potassium chloride. This process uses solutions rich in sodium nitrate to which potassium chloride is added, producing the reaction to obtain potassium nitrate.
Drying potassium nitrate using a fluidized bed is a process commonly used in industries to remove moisture or water content from solid particles efficiently. The fluidized bed drying technique involves suspending solid particles, such as potassium nitrate, in a gas stream and creating a fluid-like behaviour, similar to a boiling liquid. This way, the solid particles have increased contact with the hot gas, leading to faster and more uniform drying.
