Drying solid separation means that relatively small a mounts of liquid water or solid residues and decrease the amount of fluid is acceptable. One method of drying is to use dryer. Dryerchamber was composed one or more parts that have been each tray contemning dryer material are placed. Trays on a cycle that often takes that move them into and out of the chamber to facilitate drying. Drying operation through blowing got air (other gases).in the tray by one or more techniquescan be done. In some cases, trays and air through the mesh holes in to the material to be blown.Circulation air flow through the transfer normally takes place. In this paper trays lattice with different metal (different conductivity) was used. Trays made of nickel, brass, Iron and steel and tray was selected that circumscribe conductivity greater that other trays drying speed is higher.
