high tower washing powder pressure type Granulating Spray Dryer
Description
high tower washing powder pressure type Granulating Spray Dryer can finish drying and granulating at the same time. The needed granules with certain size and ratio can be got in accordance with requirements for process to adjust pressure, flow, and size of atomizing hole.
The tower body, pipes, separator of set, which contacts raw material, are made of SUS304. Space between inner and outer shell of tower body is filled with fine glass cotton, for heat preservation. The tower body is also equipped with observation door, sight glass, lamp-house, control meters and instruments that is controlled and displayed through electric control panel.
The heat source: steam, electric, gas fuel or oil fuel(for gas or oil, it must be equipped with air heating furnace)
Principle of work
The solution, emulsion, suspension liquid or slurry are sprayed into fine beads in the hot air, going down from the top of the drying chamber to the bottom, the water will be evaporated to and the product becomes small granular product.
Induce hot air from the top of drying tower, at the same time, pump the material liquid to the top of the tower by high pressure pump, the feeding solution becomes fine beads or small droplets through the pressure nozzle(s). When the droplets meet the high temperature hot air, the water will be evaporated immediately, and the material liquid is dried into dry product in a very short time, the product is discharged from the bottom of the drying tower, or from the cyclone (depend on the configuration). When the hot air contacts with the droplets, the temperature declines significantly, and the humidity increases greatly, and then will be exhausted by exhaust fan. The fine powder in the air will be collected through different separating devices
There’re different fine powder separation and recovery devices, such as cyclone (the common type and various combination type), bag filter, cyclone + bag filter, cyclone + wet scrubber, and bag filter + wet scrubber etc. We should different fine powder separation and recovery devices as per the characteristics of product and requirements of customer.
Depend on the product features and requirements, we might install secondary drying and cooling system (such as ZLG vibration fluid bed or pneumatic transportation), formulation system or powder sieving system etc after the spray dryer, or dehumidifier.
The particle size of the product from pressure spray dryer is normally within the range of 120mesh to 20 mesh. If bigger particles are required, we suggest FL Fluidized Granulator or re-combined agglomerator.
Features
1. The dry speed is fast and suitable for drying thermal sensitivity material particularly.
2. The finished product is ball granule with uniform size. Its
fluidity and solubility are good. The purity of product is high and
its quality is good.
3. It applied scope is wide. According to the characteristics of
raw material, it can use hot air to dry and can also use cool air
to granulate. It has strong adaptability to raw materials.
4. Its operation is simple and stable and its control is simple and
convenient and is easy to realize automatic operation.
