YPG Pressure Spray Dryer Description
YPG pressure spray dryer is suitable for solution, suspension, slurry, paste material, etc. Liquid material is atomized to small fog drops. And fog drops contact with hot air directly in the drying tower. Moisture content is evaporated instantly. So spray dryer features high efficiency, high mass transfer area, and short drying time, in general it is 5~30 seconds. Operating temperature can be adjusted according to actual situation, in general inlet air temperature is 150~500°C. And its automation control degree is control, environment solution environment can be solved.
YPG Pressure Spray Dryer Application
Foodstuff industry: Amino acid and similar substance, flavoring,
protein, starch, dairy products, instant coffee, fish powder, meat
powder, tomato paste and so on.
Pharmaceutical Industry: Chinese patent medicine, agrochemical,
antibiotics, medical drinking agent and so on.

Working Principle of YPG Pressure Spray Dryer
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.
