spray dryer

Description spray dryer The spray drying is the technology widest used in the liquid technology shaping and in the drying industry.The drying technology is most suitable for producing the powder,particle or block solid products from the materials,such as:solution,emulsion,soliquoid and pumpable paste states,For this reason,when the particle size and distribution of the final products,their residual water contents,the stacking density and the particle shape must meet the precision standard,the apray drying is one of the most desired technologies. Features After the filtering and heating,the air enters into the air distrbutor on the top of the drier.The hot air enters into the drying room in the spiral form and uniformly.By passing through the high-speed centrifugal spray on the top of the tower,the material liquid will rotate and be sprayed into the extremely fine mist liquid beads.Throug the very short time of contacting the heat air,the materials can be dried into the final products.The final products will be discharged continuously from the bottom of the drying tower and from the whirl separator.The waste gas will be discharged from blower. Applications Particle liquid name and material property:solid contents(or water contents),viscosity,surface tension and PH value. Powder material contents after the drying,permissible residual water contents,particle size,and permissible maximum temperature. Output:shift time daily. Energy that can be supplied:steam pressure supply capacity,electricty capacity,fuel coal,oil and air capacity. Control requirement:whether or not the inlet and outlet temperatures should be controlled. Powder collection requirement:whether or not the bag type collector should be mounted and what is the requirement of the environment for discharging the exhausted gas. Other special requirements.Technical parameters Item\ Data\ ModelLPG525501001502005001000Inlet Temp.
