Spray Dryer Suitable For Rapid Processing Of Paste-Like Materials
Centrifugal spray dryers (high-speed centrifugal spray dryers) are among the most widely used drying equipment in high-speed industrial production, especially suitable for directly processing solutions, emulsions, suspensions, or pastes into powder or granular products.
Main Features
Fast Drying Speed:
This is its most significant advantage. Through a high-speed rotating centrifugal atomizer, the liquid material is dispersed into extremely fine droplets (increasing by thousands of times).
Instant Powdering:
Water vapor evaporates in just 5 to 15 seconds after the droplets come into contact with hot air.
Applicability:
This "instant drying" characteristic is ideal for handling heat-sensitive materials (such as milk powder and biological agents) because the material temperature never exceeds the wet-bulb temperature of the hot air.
Six Significant Features of High-Speed Centrifugal Spray Dryers
- Extremely Rapid Drying: Drying is completed instantly, especially suitable for heat-sensitive materials.
- Excellent Quality: The finished product is spherical, with good uniformity, flowability, solubility, and purity.
- Simplified Process: Liquids with a moisture content up to 90% can be directly dried into powder in a single step, eliminating the need for crushing and screening.
- Flexible and Controllable: Particle size, bulk density, and final moisture content of the product can be controlled by adjusting operating parameters.
- Environmentally Friendly and Hygienic: The system operates in a fully enclosed manner and can be equipped with GMP-compliant designs to reduce pollution.
- Stable and Reliable: The core atomizer uses high-precision bearings, with a no-load vibration value ≤5μm and a trouble-free operating time of over 7000 hours.
Application Areas
This equipment has a wide range of applications, covering almost all industries that require the conversion of liquids into solids:
Food Industry: Milk powder, instant tea, egg powder, coffee, fruit juice powder, flavorings, etc.
Pharmaceutical Industry: Traditional Chinese medicine extracts, vitamins, antibiotics, enzyme preparations, etc.
Chemical Industry: Dyes, catalysts, silica, pesticides, fertilizers, etc.
Ceramics and New Materials: Alumina, zirconium oxide, ferrite, and other ceramic powders.
How to Select and Precautions
When selecting equipment, pay close attention to the stability and lifespan of the atomizer; determine the evaporation rate based on production capacity and material characteristics; select the appropriate heating method (electric, steam + electric, hot air furnace, etc.) based on the factory's energy situation (such as electricity, steam, natural gas); for materials that are prone to moisture absorption or have special cleanliness requirements, devices such as air sweeping and cooling jackets can be added.
