Phase preparation
Oil- and water-phase vessels, heating and addition paths are configured around the recipe and required phase condition at transfer.
Closed vacuum emulsification
Vacuum Homogenizing Emulsifying Tank
A closed emulsification vessel combining vacuum deaeration, high-shear homogenization, bulk agitation and controlled heating or cooling.
Quick answer
What this equipment is designed to do.
A vacuum homogenizing emulsifying tank processes oil and water phases in a sealed vessel using high shear, controlled bulk movement and reduced pressure. Vacuum can remove entrained air and support product appearance, density and filling behavior when the formulation and temperature profile are suitable.
Creams, lotions and ointments often change viscosity as phases combine and cool. The homogenizer must work with the anchor or wall-sweeping agitator so the complete batch reaches the shear zone without localized overheating or uncontrolled air incorporation.
Vessentra coordinates the main vessel with phase-preparation tanks, vacuum generation, condensation or pump protection, jacket utilities, transfer equipment and controls. Volatile ingredients, foaming tendency and maximum vacuum are reviewed before the operating sequence is defined.

Engineering configuration
Configured around your duty.
The equipment is developed from process inputs, operating conditions, cleaning requirements and site interfaces.
Vacuum system
Vacuum level, pump type, condensate handling and safeguards are selected from vapour load, foaming and volatile ingredients.
Combined mixing
High-shear homogenization works with anchor, frame or wall-sweeping agitation as viscosity changes through emulsification and cooling.
Recipe control
Temperature, speed, vacuum, addition steps and hold times can be coordinated through a documented batch sequence.

Common questions
Answers for project planning.
What is a vacuum homogenizing emulsifying tank used for?
It is commonly used for creams, lotions, ointments and other formulations that need controlled phase combination, high-shear homogenization, temperature management and removal of entrained air.
Does vacuum create the emulsion?
No. The rotor-stator mixer and formulation chemistry create and refine the emulsion. Vacuum manages the vessel atmosphere and can assist deaeration, controlled transfer or oxygen exposure when the process is designed for it.
Why use both a homogenizer and an anchor agitator?
The homogenizer provides intense local shear, while the anchor or wall-sweeping agitator moves viscous material through the whole vessel, supports heat transfer and returns product to the high-shear zone.
Are separate oil- and water-phase tanks always required?
Not always. They are useful when phases need independent heating, dissolution or timed transfer. The number and size of preparation vessels should follow the actual recipe and production schedule.
What should be checked before processing volatile ingredients under vacuum?
Vapour pressure, product temperature, vacuum level, condenser or pump protection, ingredient losses and safe vent handling must be reviewed before the batch sequence is approved.
