The MAXWELL 500L toothpaste vacuum emulsifying mixer (VEM-500) is a three-pot homogenizing system that blends, emulsifies and deaerates high-viscosity toothpaste paste in a single closed, vacuum-controlled cycle. It is engineered to dissolve hard-to-wet powders such as AES, AESA and LSA quickly, cut energy consumption, and deliver a glossy, lump-free product with stable texture.

Toothpaste is not simply "mixed" — it is a structured suspension of abrasives, humectants, thickeners and active ingredients. The VEM-500 processes it through an integrated cycle:
Pre-mixing (water & oil phase pots): Liquid and powdered raw materials are heated and dispersed in separate side pots, so difficult powders dissolve before they ever enter the main tank.
Vacuum transfer: The vacuum pump draws pre-mixed batches into the main emulsifying pot, eliminating manual pouring and preventing air intake.
Scraping & framing agitation: A wall-scraping anchor stirrer continuously sweeps material off the jacket wall, creating a fresh interface and preventing burnt or uneven zones.
High-shear homogenizing: The rotor-stator homogenizer shears the mass into fine particles (typically 2–200 µm), producing a uniform, creamy emulsion.
Vacuum deaeration: Because the pot is under vacuum (≈ -0.1 MPa), micro-bubbles generated during mixing are removed instantly — the key to a smooth, non-pitting toothpaste.
Discharge: Finished paste is released through a disc/bottom valve, ready for the filling line with no secondary transfer.

VEM-500 Vacuum Emulsifying Mixer Works
Strong shear disperses viscous, powder-heavy formulations and shortens production time.
Stepless timing control reduces foam under high-viscosity, low-temperature conditions.
Dissolves hard-to-wet actives (AES, AESA, LSA) faster, cutting power use per batch.
Disc-valve or bottom discharge suits all liquid-wash and paste products.
Mirror-polished product-contact surfaces meet GMP hygiene standards.
Tank working volume configurable from 10 L up to 2000 L per your output.
Imported three-layer SUS316L / SUS304-2B plate, mirror-polished, GMP-standard and anti-scald.
Automatic rising pot cover and tilt/bottom discharge for fast, safe batch changeover.
One console sets vacuum, temperature, frequency and time; buttons optional.
Frequency-converted scraper paddle cleans the wall and shortens cleaning time.
