PerMix Vacuum Mixer & Dryer

1. Loading & Sealing: Feed powders, pastes, or granulates via manual, pneumatic, or vacuum loading. The mixer is then hermetically sealed to maintain negative pressure (vacuum) during processing.
2. Blending / Agitation: Choose the mixing style that suits your product: ribbon, paddle, plow, screw, or fluidised zone. Each agitator is engineered for heat transfer and flow in vacuum conditions. (In certain builds, choppers break up agglomerates.)
3. Vacuum & Moisture Evacuation: The vacuum pump draws off moisture and air, lowering boiling points and encouraging evaporation at milder temperatures.
4. Jacketed Heating & Cooling: Multi-zone jackets allow for steam, thermal oil, or water-based heating or cooling. The goal: precise thermal control while drying.
5. Condensate Recovery / Solvent Capture: Vapours can be condensed and recovered, useful if your process involves solvents or valuable volatiles.
6. Discharge: Once mixing and drying finishes, the product exits via bottom valves or tailored discharge systems (tilt, screw assist, etc.).

• Most common layout.
• Available with ribbon, plow, paddle, screw, or fluidised zone agitators.
• Ideal for processes demanding moderate throughput and flexible blending/drying.

Vertical Vacuum Mixer / Dryer

• Saves floor space; suited to compact plants.
• Agitator types include vertical ribbon, vertical paddle, or conical screw (for gentle mixing).

• Standard: 304 / 316L stainless steel, polished internals, weld-ground surfaces.
• Alloys available: Hastelloy, Titanium, Duplex, etc.
• Seals & bearings: Suited for vacuum, gas purge, or ATEX environments.
• Full compliance: UKCA + CE marking, optional full ATEX / DSEAR certification.
• CIP / SIP readiness: Hygienic design with validation support.
• Explosion-proof controls: Motors and systems available where needed.

• Multi-zone heating/cooling jackets
• High-speed choppers for deagglomeration
• Vacuum / pressure interfaces for advanced processes
• Load cell or weighing systems for batch control
• Control systems (PLC / HMI) with recipe storage and automation
• Custom discharge mechanisms, including tilt or conveyor assists
• Instrumentation (temperature, pressure, vacuum sensors, gas purge)
• Solvent recovery systems

• Pharmaceuticals / APIs: Drying sensitive ingredients under vacuum while maintaining potency.
• Food & Nutraceuticals: Powders like plant proteins, spices, and blends requiring moisture control.
• Fine & Specialty Chemicals: Mixing and drying reactive or volatile compounds with minimal thermal stress.
• Cosmetics / Powders: Pigment blending and drying in controlled environments.
• Building Materials / Additives: Moisture control during blending of additive powders, fillers, and cement adjuncts.

Example: A UK nutraceutical producer uses a vacuum mixer/dryer to blend herbal extracts with powders while concurrently drawing off moisture, saving time and reducing contamination risk.

• Footprint & CAPEX Efficiency: One vessel does double duty.
• Energy Savings: Vacuum operability lowers thermal requirements.
• Product Integrity: Closed system reduces contamination and oxidation.
• Regulatory Readiness: Designs suited for compliance in UK/EU settings.
• Flexibility & Scalability: Lab units up to full production with modular add-ons.
• Local UK Support: FAT/SAT, commissioning, service, and spares — all aligned with UK timelines.

Use a vacuum mixer/dryer when:

• You have heat-sensitive ingredients that degrade at higher temperatures.
• You want to reduce footprint and pipework complexity.
• You require strict control of moisture or solvent recovery.
• You need a sealed system (dust, hazardous solvent, oxidation issues).
• You aim for faster cycle times and lower utility usage.

If your drying and mixing demands are modest, a standalone mixer + downstream dryer might still make sense — but for performance, integration, and control, the vacuum combo often wins in regulated industries.

When designing your vacuum mixer/dryer, consider:

• Batch volume and throughput goals.
• Moisture to be removed and acceptable final moisture.
• Heat transfer needs (ΔT, heating/cooling medium).
• Material properties (bulk density, thermal sensitivity, abrasiveness).
• Vacuum levels, gas purge, or inerting needs.
• Cleaning, validation, and hygiene constraints.
• Integration into upstream/downstream processes (loading, discharge).

Performance Born from Engineering Excellence

DP Pulverizers designs and builds mills that transform production efficiency. Every model is developed using computational airflow analysis, high-tolerance machining, and precision balancing, ensuring micron-accurate results and continuous uptime.

Our systems are built from stainless steel, Hardox, or alloy steels to suit your application — whether it’s fine sugar powders, conductive graphite, or cryogenically ground polymers. Each design meets ATEX, GMP, and CE standards, ready for industrial and pharmaceutical environments across Europe.

Our Range of Milling Solutions

Pin Mills
Delivering fine, consistent particle reduction for spices, starches, and chemical powders with high energy efficiency and minimal heat generation.

Turbo Mills
Engineered for high-speed micronizing of plastics, pigments, and resins, turbo mills use controlled turbulence for fine results without overheating.

Hammer Mills
The robust, heavy-duty solution for bulk grinding and granulation in food, minerals, and biomass processing. Available in Hardox for abrasive products.

Jet Mills
Utilizing compressed air rather than moving parts, jet mills achieve sub-5-micron fineness ideal for pharmaceutical and nano-material production.

Cryogenic Mills
Low-temperature milling using liquid nitrogen keeps materials stable, preventing softening or clumping — essential for elastomers, thermoplastics, and fine foods.

Universal Mills
A versatile platform that adapts to pin, hammer, or turbo configurations, perfect for manufacturers handling multiple product types on one line.

Cone Mills (Comils)
For gentle deagglomeration and uniform sizing, cone mills are a clean, quiet option for final powder conditioning and pre-mix applications.
