Vacuum Emulsifier Machine

High Shear Vacuum Homogenizer Mixer for Cosmetic Cream, Pharmaceutical Ointment, and Food Production

AGICO is a professional vacuum emulsifier manufacturer and vacuum homogenizer mixer supplier based in Anyang, China. Since 1997, we have been designing and manufacturing high shear vacuum emulsifying equipment for the cosmetic, pharmaceutical, food, and chemical industries.

Our vacuum emulsifying mixer integrates mixing, dispersing, homogenizing, emulsifying, and vacuum degassing into a single complete system. The equipment produces fine, stable,  high-quality emulsions — including creams, lotions, ointments, gels, sauces, and pastes — by combining high shear homogenization with vacuum technology.

What is a Vacuum Emulsifier?

A vacuum emulsifier is an industrial machine that blends immiscible liquids (such as oil and water) under vacuum conditions to create stable, uniform emulsions. Unlike conventional mixers that trap air during processing, a vacuum homogenizer emulsifier removes air bubbles, prevents oxidation, and produces bubble-free products with smoother texture and longer shelf life.

The global emulsifying homogenizer market continues to grow, driven by increasing demand for high-quality emulsions in cosmetics, pharmaceuticals, and food production. Vacuum-enabled emulsifying homogenizers are becoming essential for eliminating air bubbles — a persistent challenge in cosmetic and pharmaceutical manufacturing.

How a Vacuum Homogenizer Emulsifier Works

The vacuum homogenizing emulsifier operates through three core functions that work together: vacuum degassing, high-shear homogenization, and precise temperature control.

Vacuum Degassing

The vacuum system removes air from the emulsifying tank, creating negative pressure (vacuum degree up to -0.09 MPa to -0.098 MPa). Under this environment, air bubbles generated during mixing are extracted immediately. This prevents product oxidation, bacterial contamination, and surface defects such as pinholes or bubbles. The result is a glossy, bubble-free product with excellent spreadability.

High Shear Homogenization

Materials are drawn into the homogenizer under vacuum. The rotor and stator rotate at high speed to generate intense shearing forces. The rotor linear speed can reach over 40 m/s, and the material undergoes hundreds of thousands of hydraulic shearing, impact, and turbulence actions per minute. This breaks dispersed particles down to 0.2–5μm, producing a stable and uniform emulsion. The high shear vacuum emulsifier design ensures consistent particle size reduction, achieving fine emulsion textures required for high-end cosmetic creams and pharmaceutical ointments.

Precise Temperature Control

Our vacuum emulsifying machine is equipped with a jacketed heating/cooling system and PID temperature sensors. Heating can be electric or steam-powered, and cooling is achieved by circulating coolant through the jacket. This allows precise temperature control throughout the emulsification process, protecting heat-sensitive ingredients and ensuring consistent batch quality.

Structure of the Vacuum Emulsifying Mixer

AGICO's vacuum homogenizer consists of several integrated modules working together:

Structure diagram of AGICO vacuum emulsifying mixer

Main Emulsifying Tank

Made of stainless steel (304 or 316L), mirror-polished interior. Double-layer jacket for heating/cooling with insulation. Meets GMP sanitary standards.

Water Tank & Oil Tank

Preheat and dissolve water-phase and oil-phase materials separately before vacuum suction into the main tank.

Stirring System

Frame stirrer with PTFE scraper blades that continuously clean the tank wall, preventing sticking and sedimentation. Variable frequency drive for stepless speed adjustment.

High Shear Homogenizer

Rotor-stator homogenizing head mounted at the bottom or top. High-speed rotation (up to 3500 rpm) creates intense shearing forces for fine emulsification.

Vacuum System

Water ring vacuum pump with sealing system. Double mechanical seals ensure extremely low leakage rates.

Hydraulic Lifting System

Hydraulic cylinder lifts the tank cover or tilts the main tank for easy cleaning, maintenance, and discharge.

PLC Control System

Touchscreen interface with programmable logic controller. Stores multiple recipes, monitors temperature/speed/vacuum in real time, and automates the entire emulsification cycle.

Features of AGICO Vacuum Homogenizing Emulsifier

• High mixing and emulsifying efficiency – The dual action of high shear homogenization and frame stirring completes full emulsification in a short time, significantly improving production efficiency. An emulsification cycle typically takes only 30 to 60 minutes.
• Bubble-free product quality – Vacuum degassing completely removes air from the final product, eliminating pinholes, oxidation, and texture defects. This is essential for premium cosmetic creams and pharmaceutical ointments that require a smooth, glossy finish.
• Precise temperature management – PID-controlled heating/cooling system maintains accurate temperature throughout processing. This protects sensitive ingredients (such as vitamins, essential oils, and active pharmaceutical ingredients) from thermal degradation.
• Flexible material handling – Handles materials from low-viscosity liquids to high-viscosity pastes and creams. Suitable for water-based, oil-based, and emulsion formulations. High viscosity mixing is particularly effective due to the scraper wall stirring and high torque drive system.
• Hygienic and GMP-compliant design – All material-contact parts use stainless steel with mirror-polished surfaces. Fully sealed operation prevents external contamination. Optional CIP (Clean-in-Place) system allows automated internal cleaning without disassembly.
• Energy-efficient operation – Enclosed vacuum system reduces dust and vapor emissions. Variable frequency drives optimize power consumption based on actual load requirements. The jacketed design minimizes heat loss.

Frequently Asked Questions (FAQ)

Q1: What is the difference between a vacuum emulsifier and a homogenizer?

A vacuum emulsifier is designed for processing viscous, air-sensitive materials under vacuum — ideal for creams, ointments, and gels. A homogenizer focuses primarily on particle size reduction in low to medium viscosity liquids. AGICO's vacuum homogenizing emulsifier combines both functions in one machine.

 

Q2: What viscosity can AGICO vacuum emulsifying mixers handle?

Our vacuum emulsifying machines can process materials from low viscosity liquids to high viscosity pastes up to 50,000 cP. The scraper wall stirring system ensures thorough mixing even for thick materials.

 

Q3: Can the homogenizer and stirrer be used together?

Yes. The high shear homogenizer and frame stirrer can operate simultaneously or independently, depending on your process requirements.

 

Q4: What certifications do AGICO vacuum emulsifiers have?

Our vacuum emulsifier equipment can be manufactured to meet CE, GMP, ISO 9001, and other international standards.

 

Q5: What is the typical delivery time?

Standard delivery is 30-45 days after order confirmation, depending on model and customization requirements.
