Spray Dryer
Spray dryers atomize liquids, solutions and suspensions into fine droplets that dry into powder on contact with hot air — for consistent particle size, moisture and density.
LPG-Centrifugal Spray Dryer
Categories: Convection Dryer, Spray Dryer
Advanced Liquid-to-Powder Process:
A high-speed centrifugal atomizer at the tower's peak transforms materials into super fine liquid drops that dry quickly upon contact with hot air — perfect for precise particle size, moisture, density and shape standards.
- Input:
- Solutions, Emulsions, Suspensions
- Output:
- Powder with 3%-5% moisture content
- Temperature:
- Inlet air temperature range of 150°C to 500°C
YPG-Pressure Spray Dryer
Categories: Convection Dryer, Spray Dryer
High-Pressure Nozzle Atomization:
The Pressure Spray Dryer atomizes feed liquid through high-pressure nozzles, producing coarser and denser granules with excellent flowability — widely used for foods, chemicals and dairy powders.
- Input:
- Solutions, Emulsions, Suspensions
- Output:
- Coarse powder or granules with 3%-5% moisture content
- Temperature:
- Inlet air temperature range of 150°C to 350°C
GXP-Closed Circulation Spray Dryer
Categories: Convection Dryer, Spray Dryer
Optimal Drying for Sensitive Materials:
This explosion-proof spray dryer operates in a sealed environment, using inert gas as the drying medium to fully recover solvents from raw materials. The recyclable drying medium provides superior protection for sensitive materials.
- Input:
- Solutions, Emulsions, Suspensions
- Output:
- Powder with 3%–8% moisture content
- Temperature:
- Inlet air temperature range of 100°C to 300°C
- Suitability:
- Anaerobic, explosion-proof and low-temperature conditions
ZLPG-Extract Spray Dryer
Categories: Convection Dryer, Spray Dryer
Specialized Spray Dryer for Extracts:
The Extract Spray Dryer features a cylinder equipped with a cooling system specifically designed for drying extracts while keeping wall temperatures below 80°C. It includes an airbrush that cleans the walls during operation to prevent adhesion and protect the powder from burning.
- Input:
- Extracts (Liquid)
- Output:
- Extracts (Powder) with 3%–8% moisture content
- Temperature:
- Inlet air temperature range of 140°C to 180°C
- Additional Features:
- Freeze dehumidification, Air brush for tower cleaning
Four Spray Drying Configurations, One Core Process
SINOTHERMO's spray dryer range covers centrifugal atomization for high-speed powder production, high-pressure nozzle atomization for coarser, denser granules, closed-loop drying for solvent recovery and explosion-proof operation, and a dedicated extract spray dryer with freeze dehumidification for heat-sensitive liquid extracts.
Choosing the Right Spray Dryer for Your Feed
Centrifugal atomization suits shear-sensitive solutions needing fine, uniform particles. Pressure nozzle atomization suits feeds where coarser, free-flowing granules are the goal. Closed-circulation design suits organic-solvent or oxygen-sensitive materials. Extract-specific units suit botanical and herbal extracts where flavor and potency must survive drying.
