The drying technology is most suitable for producing the powder, particle 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 spray drying is one of the most desired technologies.
Herb extract spray dryer pressure Spray drier
YPG Pressure Spray Dryer (nozzle spray dryer)
I . Working principle and configuration options:
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. 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, 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, 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 Fluidized Granulator or re-combined agglomerator.
II . Features of our equipment:
The designs of our spray dryer are advanced in China, as well as worldwide. If we compare the important parameters of our spray dryers and some famous brand in the world, such as final moisture content, color, flavor, particle size, solubility and bulk density etc, they are very close, or sometimes, ours are even a little better. A lot of customers have achieved their desired results with our equipment.
