High Pressure Atomization Spray Drying Machine Spray Drying Tower 5 - 50 Um

Pressure Spray Drying Tower
Core Principle and Application
The pressure spray dryer converts liquid materials into fine droplets through high-pressure atomization, followed by instantaneous heat and mass transfer with high-temperature hot air flow, yielding powdered or granular finished products.
Process Stages
  • Material Pretreatment and Pressurized Conveying: Liquid materials are filtered and pressurized (2.0-20.0MPa) for transport to the atomization system
  • High-Pressure Atomization: Pressure nozzle creates fine droplets (5-50μm diameter)
  • Heat and Mass Transfer Drying: Droplets contact high-temperature air (120-350℃) for rapid evaporation
  • Finished Product Separation and Collection: Powdered products are separated via cyclone separator and bag filter

Core Structural Components
Tower Body (Drying Main Body)
Vertical cylindrical structure with polished inner walls, constructed from stainless steel (304/316L) or carbon steel with anti-corrosion coating.
Atomization System
High-pressure nozzle, pump, and filtration components for uniform droplet formation.
Heating and Air Distribution System
Hot air furnace and air distributor ensuring uniform heat distribution throughout the tower.
Separation and Collection System
Cyclone separator (90%+ efficiency) and bag filter system for product recovery exceeding 99%.
Control System
PLC-controlled monitoring of temperature, pressure, and flow parameters for process stability.
Exhaust Gas Treatment System
Scrubber, demister, and induced draft fan for environmental compliance.

Material Requirements
  • Form: Flowable liquids (solutions, emulsions, suspensions) with 10%-60% solid content
  • Thermal Stability: Must withstand 120-350℃ without decomposition or denaturation
  • Physical Properties: Quick dehydration capability, minimal corrosiveness, and non-adhesive properties

Application Industries
  • Food Industry: Large-scale production of powdered ingredients with nutrient retention
  • Chemical Industry: Polymer drying, pigment powdering, catalyst production
  • Pharmaceutical Industry: API drying, health product processing under GMP standards
  • Feed Industry: Additive drying and animal protein processing for improved shelf life
  • Environmental Protection: Sludge treatment and wastewater concentrate processing
Unsuitable Applications
  • High-viscosity, caking-prone materials that cannot be diluted
  • Highly heat-sensitive materials decomposing above 100℃
  • Materials with solid particles exceeding 100μm
  • Strongly corrosive and oxidizing materials without specialized equipment
Note: Equipment specifications and material compatibility should be verified with technical experts for specific applications.
