Vacuum Emulsify Mixer for Cosmetic & Pharmaceutical Lab R&D — VEM 5L / 10L

The VEM 5L/10L vacuum emulsify mixer is a compact laboratory vacuum emulsifying machine engineered for cosmetic, pharmaceutical and daily-chemical formula development. It pairs a lifting emulsifying pot with oil/water premix tanks, a high-shear homogenizer and a vacuum system to deliver bubble-free creams, ointments and emulsions down to 2–6 µm. For R&D benches and small-batch trials, this small batch vacuum emulsifying machine is the practical bridge from formula to production.

Watch the VEM 5L/10L Vacuum Emulsify Mixer in Operation

This vacuum emulsify mixer demo shows the 5L/10L lab unit running a real batch: the vacuum pump evacuates the emulsifying pot, the PTFE wall scraper sweeps the tank wall, and the bottom high-shear homogenizer shears the mix into a bubble-free cream — the same vacuum-emulsifying process used for cosmetic creams, pharmaceutical ointments, toothpaste and lotions.

Video transcript: The clip opens on the MAXWELL VEM-5/10L laboratory vacuum emulsifying mixer — a benchtop stainless-steel unit with an auto-lifting pot cover. The operator starts the vacuum pump; the gauge shows the emulsifying pot under vacuum. The central scraper agitator (10–120 rpm) and the bottom high-shear homogenizer (up to 3000 rpm) run together, drawing premix from the oil and water pots and producing a smooth, air-free emulsion down to 2–6 µm. Built for cosmetic, pharmaceutical, daily-chemical, food and chemical R&D and small-batch trials.

What Is a Vacuum Emulsify Mixer?

A vacuum emulsify mixer is a closed, vacuum-operated processing unit that combines low-speed wall-scraping agitation with high-speed rotor-stator shearing. Materials are heated and mixed in separate oil and water phase pots, then pulled into the emulsifying pot by a vacuum pump. Inside the pot, a central stirrer with PTFE scrapers continuously wipes material off the tank wall to create fresh interface, while the high-shear homogenizer cuts, compresses and folds the batch into uniform particles. Because the pot runs under vacuum, micro-bubbles generated during mixing are removed on the spot — preventing oxidation and improving texture stability.

In plain terms: it is the machine that turns separated oil, water and active ingredients into a stable, smooth cream. The GMP-compliant vacuum emulsifier 316L variant is the standard choice for cosmetic and pharmaceutical plants where hygiene and repeatability matter.

Key Features of the VEM 5L/10L Lab Vacuum Emulsifier

1. Auto-lifting pot cover & vacuum feeding

The emulsifying pot cover lifts automatically, and the oil/water phase materials are drawn directly into the emulsifying pot through a conveying pipeline under vacuum — no open transfer, no extra air. This is why the vacuum emulsify mixer for toothpaste and sunscreen lines stays clean and consistent.

2. High-shear homogenizer to 2–6 µm

The bottom or in-pot high-shear vacuum homogenizer mixer uses a precision rotor-stator set to shear material in the narrow gap, producing particles as fine as 2–6 µm. The homogenizing and scraping systems can run separately or together, so you control both fineness and heat transfer.

3. GMP 316L contact parts, mirror polished

All parts touching the product are SUS304 or SUS316L stainless steel with a mirror-polished inner surface. The 316L vacuum emulsifier for food sauce and pharma use meets GMP hygienic standards, with an insulation layer outside the jacket for safe, efficient heating and cooling.

4. Heating, cooling & vacuum in one unit

Electric heating pipes warm the heat-conducting medium in the jacket; temperature is set and auto-controlled. Connect coolant to the jacket for cooling. Vacuum deaeration removes bubbles during the whole cycle. Scraper agitation is variable-frequency (VFD) controlled for different viscosities.

Application Industries — Where the VEM 5L/10L Vacuum Emulsify Mixer Works

Framed by end-use, the vacuum emulsify mixer for cosmetic and pharma lines stands apart from generic listings. The VEM 5L/10L lab unit serves multiple R&D streams:

Machine Structure

The counter-rotating scraper vacuum emulsifying machine is built from a main emulsifying pot, an oil phase pot and a water phase pot, plus a vacuum system, heating/cooling jackets, temperature control and an electric control panel. The central agitator carries PTFE scrapers that always follow the tank inner wall, sweeping stuck material into the fresh mixing zone.
