A Spin Flash Dryer (Agitated Flash Dryer) is a compact, continuous system engineered to turn filter cakes, pastes, and high-moisture slurries into free-flowing powders in seconds. A high-speed disperser breaks up wet feed right inside the drying chamber while a stream of hot, high-velocity air instantly flashes off moisture. The result is uniform particle size, low residual moisture, and stable bulk density—perfect for pigments, salts, chemicals, food ingredients, and pharmaceutical intermediates.
The Spin Flash Dryer is an advanced modification of the conventional flash dryer, designed to efficiently handle paste-like, sticky, or non-free-flowing materials. It combines the principles of flash drying with mechanical agitation and dispersion to achieve high drying rates and uniform particle formation.
The principle of operation remains the same — moist material is dried by direct contact with a stream of hot air — but in a spin flash dryer, the material is first mechanically disintegrated and fluidized by a high-speed agitator (rotor) located at the base of the drying chamber. The rotor breaks the feed into fine particles and ensures intimate mixing with the hot air, allowing for very fast drying even for cohesive materials.
The Spin flash dryer consists of the following main components:
for cakes/pastes—no pre-dilution needed
minimal thermal damage and color shift
(sticky, thixotropic, crystalline) with internal back-mixing
via classifier setting, rotor speed, and air temperature control
and small footprint vs. tray or rotary drying
with easy start/stop and recipe repeatability
with enclosed solids recovery, low dusting, and CIP options
(pin/knife/hammer options) for precise shear energy
for on-the-fly particle cut-point tuning
indirect gas/LPG/HSD, steam/thermic-fluid coils, or electric
on exhaust (air-to-air/air-to-water) to cut OPEX
with differential-pressure control; HEPA final filter (hygienic duty)
for consistent moisture and better handling of sticky feeds
inlet/outlet T°, chamber ΔP, rotor amps/torque, oxygen/LEL (solvent)
smooth, drainable interiors; CIP spray lances; quick-change wear parts
Unicoco, Indonesia was excited about the Coconut project, but through GEM we made this dream come true. GEM machines: dryers / screw conveyors / bleachers / graders, etc. they are absolutely good and require little maintenance. Also, we get 24×7 support from them in case we get stuck at any time.
GO FOR IT!!!
PT Unicoconut Industries Indonesia, Indonesia
Franklin Baker Company of the Philippines, in its continued effort to be the gold standard in processed coconut products, continues to partner with the best OEM suppliers for our manufacturing line requirements. One of them is GEM Forgings, which has been our trusted supplier of process equipment for our DC (desiccated coconut) dryers. We both value quality and service level in our business dealings.
