Vacuum Emulsifying Mixer: Types, Specifications & Price Guide 2026
PEK, PVM, and PSK vacuum mixers for cosmetics and pharma — vacuum levels, sanitary construction, and factory-direct selection.
When investing in equipment for cosmetic creams, dermatological ointments, food sauces, or chemical emulsions, plant managers encounter a critical selection hurdle: "How do I determine the right vacuum emulsifying mixer configuration — balancing vacuum depth, rotor-stator shear speed, and sanitary polishing standards — without overpaying for unnecessary add-ons or under-specifying thermal control?" Operating under vacuum is essential to eliminate micro-aeration, prevent oxidative spoilage, and achieve a glossy, mirror-smooth emulsion.
If you want to compare equipment brands across the broader market landscape, see our comprehensive Top Chinese Vacuum Emulsifying Mixer Manufacturers 2026 Guide. This guide focuses on technical specifications, operating principles, and pricing drivers across POLYC's three core vacuum mixer families — PEK Emulsifying Kettles, PVM Vacuum Dispersers, and PSK Multi-Function Reaction Kettles — so you can accurately specify your requirements before requesting a quotation.
POLYC has supplied vacuum emulsifying mixers to cosmetic and pharmaceutical manufacturers — detailed case study coming soon.

Vacuum Emulsifying Mixer Types Compared: PEK vs. PVM vs. PSK
| Mixer Series | Agitation & Rotor Architecture | Vacuum Capability | Batch Volume Range | Sanitary Metallurgy | Relative Price Tier |
|---|---|---|---|---|---|
| PEK Series — Emulsifying Kettle | High-shear stator-rotor homogenizer (2,900 rpm) + Slow anchor agitator with flexible PTFE wall scrapers | Up to -0.095 MPa (Full Vacuum) | 100 L – 3,000 L | SUS304 / SUS316L (Mirror Polish Ra < 0.4 μm) | Mid-to-High Cosmetic Tier |
| PVM Series — Vacuum Disperser | Single/Dual high-speed Cowles dispersing disc (0–1,500 rpm) under a sealed vacuum cover | ≤ -0.080 MPa (Standard Vacuum) | 200 L – 5,000 L | SUS304 / Carbon Steel / SUS316L | Entry-to-Mid Industrial Tier |
| PSK Series — Multi-Function Kettle | Triple-shaft configuration: Dual high-speed dispersers + In-line homogenizer head + Outer anchor scraper | Up to -0.098 MPa (Deep Vacuum) | 300 L – 10,000 L | SUS316L / SUS304 / Sanitary Pharma Finish | Premium Heavy Compounding Tier |
*Note: Pricing scales according to automation level (manual valves vs. automated SCADA loss-in-weight batching), heating jacket method (electric, steam, or thermal oil), and sanitary surface roughness ratings.
How to Choose Your Vacuum Mixer Configuration
Selecting the correct mixer depends on fluid viscosity, required droplet fineness, de-aeration demands, and industry compliance requirements:
Scenario 1: Cosmetic Creams, Lotions & Body Emulsions
Best Choice: PEK Series Vacuum Emulsifying Kettle
Cosmetic skin creams and personal care lotions require sub-micron droplet refinement (1–5 μm) and mirror-like glossy finishes. The PEK series combines an intense bottom or top homogenizer head with wall-scraping anchor blades, degassing entrained air under continuous vacuum to ensure long shelf stability without phase separation.
Scenario 2: Vacuum Paint, Ink & Coating De-aeration
Best Choice: PVM Series Vacuum Dispersing Machine
For architectural coatings, specialty inks, and chemical pastes where powder wetting and micro-bubble removal are needed but heavy droplet homogenization is unnecessary. The PVM applies a sealed vacuum hood (≤ -0.08 MPa) over a high-velocity Cowles blade, preventing foaming and vortex aeration.
Scenario 3: Complex Viscous Gels & Medical Pastes
Best Choice: PSK Multi-Function Dispersing Kettle
When processing high-viscosity thixotropic formulations containing difficult-to-wet fillers (e.g., Carbomer gels, medical ointments, silicone pastes), the PSK's triple-shaft action shatters lumps while the deep vacuum (-0.098 MPa) extracts voids. For ultra-heavy pastes (>300,000 cps), explore our high viscosity mixer guide.
Important Note on Pharmaceutical & Food Compliance
POLYC manufactures industrial-grade and sanitary-grade mixing vessels using certified SUS304 / SUS316L stainless steel with mechanical mirror polishing. However, POLYC is not a specialized pharmaceutical validation agency (e.g., dedicated FDA / EU-GMP validation consultancy). Clients producing regulated pharmaceuticals or food items must review local regulatory standards to verify that our mechanical specifications align with their site-specific validation protocols.
Product Line Breakdown & Technical Capabilities
1. PEK Series — Vacuum Emulsifying Kettle
The PEK series is the cornerstone for cosmetic emulsions and personal care lotions. It integrates a bottom or top-mounted high-shear rotor-stator homogenizer running at 2,900 rpm with a bi-directional slow anchor frame (20–45 rpm).
Spring-loaded PTFE scrapers wipe the heated jacket wall to enhance thermal transfer, while continuous vacuum suction extracts air bubbles generated during high-shear homogenization.
2. PVM Series — Vacuum Dispersing Machine
The PVM series provides heavy-duty powder dissolution and de-aeration for high-grade coatings, liquid adhesives, and synthetic chemical pastes. Operating under vacuum levels down to -0.080 MPa, it prevents airborne dust escape during dry pigment loading.
Equipped with hydraulic cover lifting and variable speed drives (VFD), the PVM allows smooth speed regulation to establish an optimal toroidal flow vortex without surface aeration.
3. PSK Series — Multi-Function Dispersing Kettle
The PSK series is an all-in-one multi-shaft compounding reactor built for demanding formulations. It combines three independently driven agitation shafts — dual high-speed dispersing discs, an in-line homogenizing head, and an outer anchor scraper frame.
Capable of holding deep vacuum (-0.098 MPa) and high jacket pressures, the PSK eliminates the need for multiple intermediate tanks by executing powder wetting, fine grinding, and degassing in a single vessel.
What Factors Drive the Price of a Vacuum Emulsifying Mixer?
When evaluating commercial proposals for vacuum emulsifiers, quotations vary based on four core engineering specifications:
1. Vacuum Seal Engineering & Pump System
The choice of vacuum pump (rotary vane vs. water-ring vacuum pump) and shaft sealing mechanism (single mechanical seal vs. pressurized double-end cartridge mechanical seal with barrier fluid) directly affects seal longevity and machine cost.
2. Sanitary Metallurgy & Surface Polishing
Standard industrial mixers use SUS304 with mill finishes. High-grade cosmetic and sanitary units require certified SUS316L wetted surfaces with mechanical mirror polishing (Ra < 0.4 μm) or electro-polishing to prevent bacterial contamination and facilitate CIP washdowns.
3. Thermal Jacket Design & Insulation
Three-layer vessel construction (internal product chamber, thermal heating/cooling jacket with spiral baffles, and outer thermal insulation cladding with welded stainless steel sheeting) adds significant manufacturing precision compared to single-wall vessels.
4. Degree of Automation & Hydraulic Lifting
Options range from manual push-button stations to automated PLC touchscreen consoles with pneumatic valve sequencing, temperature curve logging, and motorized hydraulic tank cover lifting with safety limit switches.
