High Viscosity Combined Fixed Type Vacuum Emulsifying Mixer for Cream Ointment

Vacuum Emulsifying Mixer Introduction

The Vacuum Emulsifying Mixer by Guangzhou Hengyu is the definitive equipment for manufacturing high-viscosity creams, premium laundry gels, and personal care products like shampoos. This integrated system combines vacuum deaeration, multi-axial blending, high-shear homogenization, and thermal management (heating/cooling) into a single unit. It ensures a superior finished product characterized by a smooth texture, zero air bubbles, and long-term stability against phase separation.

Key Features & Technical Advantages

Triple-Action Agitation System: Engineered with a bi-directional frame-type scraper agitator paired with a high-shear central homogenizer. The food-grade PTFE (Teflon) scrapers continuously remove wall-clinging materials, ensuring a 100% heat transfer efficiency and uniform mixing for viscous formulas.

Superior Vacuum Deaeration (Defoaming) : Operating under a high vacuum environment of up to -0.09 MPa, the system performs material processing that thoroughly eliminates micro-bubbles. This process significantly extends the product’s shelf life and enhances the final visual clarity and luster.

Hydraulic Lifting & Tilting Discharge: Featuring a hydraulic lift system for the vessel lid and a tilting mechanism for the main tank, this design allows for effortless discharging and deep cleaning. The system is fully compliant with GMP (Good Manufacturing Practice) hygiene standards and is ideal for quick product changeovers.

Precision Thermal Management (Temperature Control) : The jacketed vessel supports both electric and steam heating modes, integrated with a rapid water-cooling system. This allows for high-precision temperature control, providing essential protection for heat-sensitive active ingredients and ensuring consistent batch quality.

Working Principle

The water-phase and oil-phase materials are heated and stirred separately in their respective tanks before being transferred via vacuum pump into the emulsification vessel. Inside the emulsifier, a centrally mounted paddle stirs the mixture from above while a PTFE wall-scraper ensures continuous material exchange and uniform thermal transfer, guiding the mixture downward to a high-speed shear emulsifier located at the lower end of the central shaft.

Operating at ultra-high speed, the emulsifier intensively cuts, shears, and disrupts the material, reducing it to fine particles ranging between 200 nm and 2 μm. Throughout the process, any bubbles generated are immediately removed under the maintained vacuum environment, ensuring a smooth, homogeneous, and bubble-free emulsion suitable for high-quality product applications.
