Operating Principle

Versator Chamber DiagramThe Versator’s principle of operation relies on the spreading of a thin film of aerated liquid on the inside of the rotating Versator Disc under high vacuum to remove entrapped air, foam, or gas.

During operation, the Versator chamber is under high vacuum and the Versator Disc is rotating. The vacuum is typically 28-29″ Hg and the disc speed may range from 1200-6000 RPM depending on the Versator model.

The vacuum draws the aerated liquid to the Versator and into the Feed Assembly.

At the end of the Feed Assembly, the Spreader Ring has a close clearance with the inside surface of the Versator Disc. When the flow of aerated liquid passes through this clearance, it forms an even thin film of liquid.

The rotation of the Versator Disc centrifuges the thin film of liquid across the interior surface of the Versator Disc. While the liquid travels across the Disc, the high vacuum draws off the entrapped bubbles from the thin film.

When the deaerated liquid reaches the inner edge of the Versator Disc, the rotation forces the liquid up a special pipe assembly which fits closely to the surface of the Disc and out of the Versator Chamber. The air, foam, or gas removed from the liquid exits the system through the vacuum pump’s discharge or exhaust. The Versator Chamber does not fill; the liquid stays within the Versator Disc.

The Versator’s operation is accomplished in a fraction of a second.

Features of the Cornell Versator

  • Removal of entrapped air, foam, or gas from liquids under high vacuum.
  • Efficient mixing, blending, homogenization, dispersion, emulsification, removal of moisture or distillation of residuals as a simultaneous secondary benefit.
  • The principle of operation is the same for each Versator model size.
  • Process virtually any pourable or pumpable liquid – hot or cold – from water to hot chewing gum.
  • Heat sensitive and shear sensitive products can be processed.
  • Design allows all of the processed material to be exposed in a thin film to high vacuum.
  • Continuous operation (no timed cycle) and can be installed in-line or used for batch processing.
  • Additional pumps for feed and discharge are not necessary in most installations. Material can be discharged from vacuum chamber by operating design.
  • Few spare parts subject to wear and easy access to interior parts for inspection and cleaning. Minimal product loss during operation.

The Versator’s operation is simple but it can accomplish a variety of actions:



Distillation of residuals
Removal of moisture traces
