A method of producing a dry powder from liquid or slurry by rapid drying with a hot gas. This method is known as spray drying method and is used in pharmaceutical and food industry. All spray dryers use some kind of atomizer or spray nozzle to disperse the liquid or slurry into a controlled drop size spray. There are two common types of dryers which are freeze dryer which is used for degrading the product in spray drying. It is considered as expensive batch process and is not free flowing. Drum dryer is less expensive and is continuous process for low value products. It creates flakes instead of free flowing which is very much different than that of freeze dryer.Spray dryer an equipment or device used in spray drying. It takes the liquid stream and separates the solute as solid and the solvent into the vapor as for the applications like food which consists of milk powder, coffee, tea, eggs, cereals, spices and flavorings. For pharmaceuticals it has antibiotics, medical ingredients, addictives etc. In industries ceramic materials, catalyst support. Spray drying is considered as the most expensive technology in the industrial mechanism for particle formation and drying. The activity is carried for the solid material which is either in powder, granulate form. The spray dryers are totally engaged in the fabrication of modern machine. Spray dryers are capable of drying product instantly when compared to the other technique of drying which is completely different.
The benefits of the hydro spray dryers are it has uniform quality. It also has unbeatable performance and also versatility. Traceability is the key factor of this machine. This machine is well equipped with a number of special design features including atomizer as well as controlled flow nozzle. The types of spray dryers are industrial dryers, two stage dryers, fluidized spray dryers, glass laboratory spray dryers. These machines are made using high quality material and ensure reliable operation.
