ZJR Series

Vacuum Emulsifying Mixer

The ZJR series vacuum emulsifying mixer is a mature, cost-effective integrated mixing and homogenizing equipment independently developed by YeKeey.

Combining vacuum deaeration, low-speed wall-scraping stirring and high-shear circulating homogenization, this machine steadily solves common production problems such as material delamination, large particle size, bubble residue and poor texture uniformity.

Widely applicable from laboratory formula research, small batch trial production to formal industrial mass production, the ZJR emulsifier delivers stable and repeatable emulsification results for medium and high viscosity materials.

With standard sanitary design and flexible expandable configuration, it is an ideal core processing machine for medium and small enterprises as well as production factories.

Why the ZJR Series Outperforms Standard Emulsifiers

①. Dual Counter-Rotating Agitation: Zero Dead Zones, Perfect Homogenization

Unlike single-direction mixing systems, the ZJR series features a bidirectional counter-rotating mixing system combining a center agitator with a wall-scraping scraper. This design:

Eliminates material buildup on tank walls, even for high-viscosity formulations (up to 80,000 mPa·s)

Ensures uniform heat transfer and temperature control for sensitive ingredients

Produces stable emulsions with particle sizes as low as <5μm, with consistent texture across every batch

②. Interchangeable Rotor-Stator Assemblies: One Machine, Endless Applications

The ZJR series uses modular, quick-change rotor-stator designs to adapt to diverse process needs without retooling:

Multi-Functional (Type A)

Versatile for general emulsification and mixing

Ultra-Fine (Type B)

Achieves nano-level particle sizes for high-end skincare serums

High-Viscosity (Type C)

Optimized for thick ointments, pastes, and gels

Dispersion (Type D)

Ideal for pigment processing and powder-in-liquid dispersion

③. Fully Scalable Platform: Linear Scale-Up from Lab to Production

The ZJR series is built on a process-consistent design philosophy, ensuring formulations developed on lab models translate seamlessly to full production:

Lab Scale

Compact units for R&D, formula optimization, and small-batch trials

Pilot Scale

Intermediate models for process validation and scale-up testing

Production Scale

Industrial-grade units for high-volume manufacturing

Every Scale, Every Emulsification Need

Model Tier	Capacity Range	Key Use Cases
Lab Scale	5L – 10L	R&D, formula development, regulatory trials
Pilot Scale	30L – 150L	Process validation, low-volume pilot production
Production Scale	250L – 2500L	Commercial manufacturing, high-volume runs

All models feature the same core engineering principles—counter-rotating mixing, interchangeable rotors, and vacuum homogenization—ensuring process consistency across your entire product lifecycle.

Applications Across Industries

The ZJR series is trusted by manufacturers worldwide for producing:

Cosmetics & Personal Care

Perfect for face cream, body lotion, essence, ointment, sunscreen, hair conditioner and various skin care emulsified products.

Improve product fineness, avoid oil-water separation and enhance texture stability.

Pharmaceutical Industry

Suitable for medical ointments, topical creams, suspensions and medical daily care products.

Closed vacuum production meets pharmaceutical hygiene requirements and ensures production safety.

Food & Condiment Processing

Used for mayonnaise, salad dressing, jam, sauce and high-viscosity food additives.

Vacuum processing retains original flavor and prevents deterioration caused by air mixing.

Daily Chemical & Fine Chemicals

For detergent emulsions, adhesives, latex materials and other fine chemical emulsification and mixing procedures.

Key Components & Structure of the ZJR Emulsifier

Every ZJR emulsifier is built with a modular, hygienic design optimized for performance, safety, and easy maintenance. Here’s a breakdown of its core components:

1. Main Emulsification Tank (316L Stainless Steel)

The heart of the system, where all mixing, homogenization, and emulsification take place.

Sanitary Construction: Made of pharmaceutical-grade 316L stainless steel, with mirror-polished surfaces to meet GMP standards.
Tilting Design: The tank can be fully inverted for easy discharge and thorough cleaning.
Jacketed Heating/Cooling: A double-layer jacket allows precise temperature control via steam or chilled water circulation.

2. High-Shear Homogenizer (Rotor-Stator Assembly)

Mounted at the bottom of the tank, this interchangeable unit is responsible for the high-shear processing.

Modular Design: Quick-change rotor-stator heads (Type A/B/C/D) adapt to different formulations, from low-viscosity lotions to high-viscosity ointments.
High-Speed Operation: Capable of stable speeds up to 6000 RPM, producing particle sizes as small as <5μm.

3. Dual Agitation System

The patented counter-rotating mixing system ensures no material is left untouched.

Center Agitator: A central impeller that circulates the bulk material, keeping it in constant motion.
Wall-Scraping Scraper: A PTFE or silicone blade that follows the tank’s contour, preventing material from burning or sticking to the heated walls.

4. Vacuum System

A built-in high-vacuum pump creates a negative pressure environment inside the tank.

Bubble-Free Emulsions: Eliminates air entrapment during mixing, preventing oxidation and ensuring a smooth product texture.
Material Transfer: Uses negative pressure to automatically suck raw materials from the pre-mix tanks into the main chamber, reducing contamination risks.

5. Control & Automation System

The intelligent PLC control panel manages every parameter of the process.

Touchscreen Interface: User-friendly controls for speed, temperature, vacuum level, and mixing time.
Recipe Storage: Save and recall production recipes to ensure batch-to-batch consistency.
Safety Interlocks: Built-in protection for overheating, overpressure, and equipment malfunction.

6. Water & Oil Pre-Treatment Tanks

These auxiliary tanks are dedicated to preparing the water and oil phases.

Independent Heating & Stirring: Each tank has its own heating jacket and agitator to ensure full dissolution of ingredients before they meet in the main tank.

How the ZJR Vacuum Emulsifier Works

The emulsification process in the ZJR series is a precisely controlled, continuous workflow designed to transform two immiscible phases (water and oil) into a stable, homogeneous emulsion.

1. Phase Preparation & Pre-Mixing

The oil phase (oils, waxes, lipophilic ingredients) and water phase (water, surfactants, hydrophilic ingredients) are separately heated, stirred, and dissolved in dedicated water and oil tanks. This step ensures all raw materials are fully prepared before entering the emulsification chamber.

2. Vacuum Suction & Homogenization

Using negative pressure, the pre-mixed water and oil phases are automatically drawn into the main emulsification tank. The high-shear rotor-stator homogenizer then begins operating at up to 6000 RPM, subjecting the mixture to intense mechanical forces:

Shear: The high-speed rotor cuts the fluid against the stationary stator, creating micron-level droplets.
Impact: The material is repeatedly accelerated and decelerated within the narrow gap, further reducing particle size.
Turbulence: High-frequency eddies break down larger droplets, ensuring uniform dispersion.

3. Counter-Rotating Mixing & Scraping

While homogenization occurs, the center agitator and wall-scraping scraper rotate in opposite directions:

The scraper continuously removes material from the tank walls, preventing buildup and ensuring uniform heating/cooling.
The center agitator maintains circulation, eliminating dead zones and guaranteeing every droplet passes through the high-shear zone.

4. Cooling & Finishing

After emulsification is complete, the system circulates cooling water through the jacket to bring the product to the target temperature. The final step under vacuum removes any trapped air bubbles, resulting in a bubble-free, shelf-stable emulsion ready for discharge.
