1000L Vacuum Emulsifying Mixer & Cosmetic Making Machine (VEM-1000)
What Is a Vacuum Emulsifying Mixer?
A vacuum emulsifying mixer is an industrial machine that blends immiscible liquid and solid ingredients into a stable, homogeneous emulsion. It combines a main emulsifying pot, pre-heating water pot, pre-heating oil pot, vacuum system, high-shear homogenizer, scraping agitator, heating/cooling jacket and control cabinet in one integrated unit.
Unlike simple stirring tanks, the VEM machine works under vacuum. The vacuum removes air bubbles generated during mixing, improves particle-size reduction and extends product shelf life. The high-speed rotor-stator homogenizer cuts particles down to 2–6 μm, which is essential for premium cosmetic creams and pharmaceutical ointments.

Easy Operation & Cleaning
Button panel or PLC touch screen; hydraulic lifting on large models for cleaning and inspection.
Working Principle & Process Flow
The MAXWELL vacuum emulsifying mixer follows a closed, automated batch process:
Pre-dispersion: Oil-phase and water-phase raw materials are loaded into separate pre-heating tanks. Each tank has its own stirrer and jacket for controlled heating.
Vacuum transfer: Heated materials are drawn into the main emulsifying pot by a vacuum pump, minimizing exposure to air.
Scraper mixing: A Teflon scraper agitator sweeps the inner wall at 10–120 rpm, preventing material buildup and creating fresh interfaces for emulsification.
High-shear homogenizing: The rotor-stator homogenizer spins at up to 3000 rpm, cutting the dispersed phase into micron or sub-micron droplets.
Vacuum degassing: Air bubbles are continuously removed under vacuum, resulting in a smooth, glossy cream.
Discharge: Finished product is discharged through a bottom valve or pumped to downstream filling equipment.

Key Features & Competitive Advantages
Why Choose MAXWELL VEM Series?
Three-layer stainless steel pot body: Inner layer, jacket layer and insulation layer welded as one unit for efficient heating, cooling and operator safety.
Variable frequency speed control: Both scraper stirring (10–120 rpm) and homogenizing speed can be adjusted to match different viscosities.
Sanitary mirror polishing: Inner surfaces polished to Ra ≤ 0.8 μm, fully conforming to GMP requirements.
Fast dissolving of hard-to-wet powders: High-shear head rapidly disperses AES, AESA, LSA and other surfactants, shortening batch time.
Modular mixing heads: Optional anchor impeller, paddle, helical ribbon, dispersing disc or double planetary configurations for specialized formulations.
Overseas-standard electrical components: Motors, inverters and control elements selected for 380V/50Hz or custom voltage requirements.
CE-compliant safety design: Vacuum protection, over-temperature alarm and emergency stop integrated.

Three Questions to Decide Faster
What is your daily output target? A single 100L batch serves pilot lines; an 800L batch (VEM-1000) covers industrial daily demand.
What is the viscosity and temperature sensitivity? High-viscosity pastes need larger homogenizer power (7.5–11 kW on 500L–1000L models).
Do you need filling integration? Pair the mixer with a filling production line or tube filling & sealing machine for a turnkey line.
