Drying Unit — Implemented in DyssolPro

Spray Dryer Simulation for Solids Processes

Model co-current and counter-current spray drying inside a full dynamic flowsheet. Track droplet evaporation, particle growth, outlet moisture, and downstream separation — all in one process simulation.

Proven on industrial flowsheets including porcelain tile manufacturing and zeolite production. Backed by TUHH research.

Two dedicated variants in the library

Ready to drop into any flowsheet, no generic drying placeholder required.

Both co-current and counter-current spray dryers are first-class units. Configure them, connect upstream nozzles and downstream cyclones, and run the flowsheet.

Implemented unit

Spray dryer co-current

Feed and gas flow in the same direction. Suited for thermally sensitive products.

Implemented unit

Spray dryer counter-current

Feed and gas flow opposite. Used for longer residence times and tighter moisture targets.

Other implemented units that sit upstream or downstream of a spray dryer.

Every unit below is implemented and ready to connect in a realistic process model.

What DyssolPro brings

Capabilities that matter for spray drying process teams.

Dynamic flowsheet simulation

Time-dependent simulation covering startup, shutdown, batch, semi-batch, and continuous operation.

Multidimensional solids properties

Particle-centered modeling with interdependent properties: size, composition, and moisture across connected units.

Population-balance workflows

Full PSD tracking for spray drying tasks where droplet and particle evolution matter.

Custom model development

Model Maker for implementation, testing, and validation of company-specific spray dryer models.

Related application examples

Documented flowsheets where spray drying is one step of the full process.

Existing application example

Industrial zeolite production

End-to-end catalyst process with synthesis, decanter washing, spray drying, and rotary-kiln calcination. Dyssol connected the downstream units into one process-level flowsheet.

Technical FAQ

Does DyssolPro include spray dryer models out of the box?

Yes. Both spray dryer co-current and spray dryer counter-current ship with the software.

Can spray drying be evaluated together with other process steps?

Yes. Existing examples place spray drying inside porcelain tile manufacturing and industrial zeolite production flowsheets.

Is this limited to steady-state studies?

No. DyssolPro is a dynamic flowsheet simulator and supports time-dependent process behavior by default.

What if a project needs a more specific spray dryer model?

Model Maker supports custom model development, and DyssolTEC offers implementation services for company-specific models.
