| LPG Series High-Speed Centrifugal Spray Dryer |
Descriptions
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.
Principle of Work
After the filtered and heated,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.
Features
The drying speed is high when the material liquid is atomized,the surface area of the material will increase greatly.In the hot-air flow,95%-98% of water can be evaporated at a moment.The time of completing the drying needs only several seconds. This is especially suitable for drying the heat sensitive materials.
Its final products own the good uniformity,mobility,dissolving capacity,And the final products are high in their purity and good in their quality.
The producition procedures are simple and the operation and control are easy.The liquid with the moisture contents 40-60%(for special materials,the contents may reach 90%).can be dried into the powder or particle products once a time.After the drying,there is no need for smashing and sorting,so as to reduce the operation procedures in the production and to enhance the product purity.The product particle diameters,looseness and water contents can be adjusted through changing the operation condition in a certain scope.It is very convenient to carry out the control and managment.
