Spray freeze drying combines atomization, freezing and sublimation in one system. The liquid feed is atomized into fine droplets and frozen instantly, so frozen material does not transfer to a separate dryer — which reduces handling and secondary-contamination risk. The minimum freezing temperature can reach around -71 °C, and the fine particle structure expands surface area for faster drying and better solubility.
Who this is for
Where it is used
- Extracts and concentrates — botanical, coffee and fruit concentrates turned into fast-dissolving powder.
- Nutraceutical actives — heat-sensitive ingredients where activity retention matters.
- High-value liquids — products where particle size, solubility and flow define the finished powder.
How to choose a configuration
Feed compatibility
Viscosity, solids content and target particle size determine the atomizer and freezing configuration.
Collection and scale
Yield, residual moisture or water activity, and cleaning needs define the collection method and scale-up limit.
Customization scope
Atomizer type, freezing configuration, collection method and cleaning features are configured per feed. A feasibility trial establishes cycle time, yield and quality before the machine is specified — those numbers are not assumed.
Quality control
After-sales and maintenance
Operating documentation is included, with remote support and spare-part guidance. Maintenance guidance covers the atomizer, freezing path and vacuum system.
How pricing works
Price follows the atomizer, freezing configuration and collection method. A feasibility trial is the first step: it defines the configuration and prevents paying for capability you do not need.
Frequently asked questions
Is spray freeze drying the same as spray drying?
No. Spray drying uses heat; spray freeze drying freezes the droplets and removes water by sublimation, which preserves more heat-sensitive material.
What if my feed does not atomize well?
Share the viscosity and solids content. We assess atomizability before recommending the configuration.
Can you prove yield before I buy?
Yes — a feasibility trial establishes yield, residual moisture and quality for your feed before specification.
