Vacuum Mixers & Dryers — Powder & Paste
Eleven vacuum geometries, one engineering discipline. The product's shear tolerance, flow behaviour and drying duty pick the machine — we build them all, so the recommendation follows your material, and every quotation carries trial-measured numbers.
Find Your Geometry
Three answers narrow eleven geometries to the two worth trialling. No form, no email — just engineering.
Vacuum Powder Mixers & Dryers
Vacuum Ribbon Mixers & Dryers
Counter-current double helix — the flagship blend-and-dry geometry with the highest heat-transfer area per litre and full published spec tables, 5 to 30,000 L.
Specs & Models »
Vacuum Paddle Mixers & Dryers
Heated shaft and paddles — up to 90% more drying area. Filter cakes, sludges, battery materials and the sticky phase everything else stalls on.

Vacuum Plow Mixers & Dryers
Mechanically fluidized bed with choppers — wet granulation and drying in one vessel for cohesive and fibrous products.

Vacuum Double Cone Mixers & Dryers
Rotating vessel, zero internals — the pharma reference for zero-shear drying of APIs and crystals with total discharge.
Learn More »
Vacuum V-Blenders & Dryers
Twin-shell split-and-recombine tumbling with jacketed shells — blend, dry and deaerate in the same rotation cycle.
Learn More »
Vacuum Fluidized Zone Mixers & Dryers
Twin-shaft weightless-zone blending — uniformity in 30–90 seconds at near-zero shear, with vacuum drying on board.
Learn More »
Vacuum Hi-Speed Granulator Mixers & Dryers
Single-pot processing — high-shear granulation with endpoint detection, then in-bowl vacuum drying. OEB 4/5 capable.
Learn More »
Vacuum Conical Mixers & Dryers
Orbiting-screw cone — the gentlest agitated dryer, 10–100% fill flexibility, total discharge, big single batches.
Learn More »
Vacuum Drum Mixers & Dryers
Rotating jacketed drum with engineered flights — one polished surface, near-zero shear, large volumes.

Vacuum Planetary Mixers & Dryers
Orbiting blades sweep the full bowl beyond 6 million cP; deep-vacuum deaeration to ≤ 10 mbar; optional high-speed disperser. Battery slurries, adhesives, sealants, energetics.

Vacuum Sigma Mixers & Dryers
Counter-rotating Z-blades for the heaviest masses made — devolatilise, dry and deaerate while kneading, with extrusion-screw discharge. Electrode pastes, sealant masses, gum bases.

Read down for the constraint that governs your process — then let a trial confirm it.
| Your Constraint | First Choice | Also Consider |
|---|---|---|
| Blend + dry, general purpose, best heat-transfer area | Vacuum Ribbon | Vacuum Paddle |
| Filter cake / sludge with a sticky drying phase | Vacuum Paddle | Vacuum Plow |
| Wet granulation + drying, cohesive or fibrous product | Vacuum Plow | Hi-Speed Granulator |
| Crystals / APIs — shear must be zero | Double Cone | V-Blender, Drum |
| Pharma blend + dry with fastest tumble action | V-Blender | Double Cone |
| Seconds-fast blending of fragile powder, then dry | Fluidized Zone | Vacuum Ribbon |
| Contained one-pot pharma granulation suite | Hi-Speed Granulator | Vacuum Plow |
| Large gentle batches, total discharge, part-batches | Conical Screw | Drum |
| Catalysts / coated granules, simplest cleaning | Drum | Double Cone |
| Slurry or paste that still flows — deaerate & disperse | Planetary | Sigma |
| Mass too stiff to pour — knead, devolatilise, extrude | Sigma | Planetary |
All eleven QuantumX geometries are also built as standard atmospheric mixers — same engineered agitator, jacket and validation, without the vacuum system. Standard ribbon mixers & blenders are documented in full with PRB/PVR spec tables; ask for standard-model specifications of any other geometry. For steady-state duties, Continuous Mixers & Dryers run to 60 t/h.
Not Sure Which Geometry? That's the Point of the Trial.
Send the material, the solvent and the target endpoint. We'll run it on candidate geometries and show you the drying curves side by side.
