SS304 Small Spray Dryer Spray Drying Machine Used In Laboratory
Spray drying machine in the lab, also known as small spray dryer, is a kind of laboratory instrument mainly for processing liquid materials. Generally, the whole laboratory spray dryer is compact in design and can be moved. The machine is self-contained and does not require auxiliary facilities.
Spray dryer principle
Spray drying technology is a systematic method that is applied to the drying of materials. Through mechanical action, it disperses the materials to be dried into very fine mist-like particles, (increasing the area of water evaporation, accelerating the drying process) and hot air contact, removing most of the water in an instant, so that the solid material in the material is dried into a powder state.
The air enters the air distributor at the top of the drying tower through the filter and heater and then enters the drying chamber evenly in a spiral shape. The material liquid is sent from the material liquid tank to the centrifugal atomizer at the top of the drying tower by the filter and pump so that the liquid is sprayed into very small droplets. The end product is discharged from the bottom of the drying tower and the cyclone separator while the exhaust gas is discharged by the fan.
Features
1.compact structure, effective heat transfer area, small area
2.The mixing is uniform, high thermal efficiency, good drying effect
3.the blade shaft can mesh with each other, with self-cleaning effect, can prevent the material wall
4.Even of low energy consumption, small operating costs
5.small dust entrainment, less material loss
6.Indirect heating, no material pollution
7.The low rotation speed of liraglug impeller shaft, does not damage the product shape and properties
8.Therefore the device to operate flexible, smooth and reliable operation
Centrifugal spray atomizer Features
1.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 is only several seconds. This is especially suitable for drying the heat sensitive materials.
2. Its final products own the good uniformity, flow ability & solubility. And the final products are high in purity and good in quality.
3. The production procedures are simple and the operation and control are easy.The liquid with moisture contents of 40-60%(for special materials,the contents might be up to 90%).can be dried into the powder or particle products once a time. After the drying process, 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 within a certain range. It is very convenient to carry out control and managment.
