Vacuum Homogenizer Vs Mixing Tank: Which One Is Better For Cosmetics?

→A mixing tank is a basic processing device used for mixing, stirring, heating, and homogenizing raw materials.

It typically consists of the following parts:

Stainless steel tank

Agitator

Homogenizer (optional)

Motor and gearbox

Heating/cooling jacket

Control panel

→Main functions:

Mixing raw materials
Homogeneous shearing emulsification of raw materials, such as uniformly mixing oil, water, powder, etc.
Heating and cooling products

→Suitable Products:

A mixing tank is commonly used for:

Liquid soap

Lotion
Shampoo (low viscosity)

Cosmetic cream
Shower gel
Detergent
Hand sanitizer
Toner

→Advantages:

✔ Simple structure
✔ Easy operation
✔ Lower investment cost
✔ Easy maintenance

→A vacuum homogenizer is an advanced cosmetic processing device designed specifically for producing high-quality emulsions.

It typically consists of the following parts:

High speed shear homogenizer system 

Vacuum degassing system

Heating and cooling system

Scraper mixing system

→Main functions:

High Shear Homogenier

*High-speed shear homogenization is a process that breaks immiscible materials (such as oil and water) into tiny, uniform particles to form a stable emulsion.

Frame mixing with scrapers

*It assists in stirring and reduces product adhesion to the inner wall of the tank.

Vacuum degassing from product

*The vacuum system removes air bubbles, improving:Product Appearance,Stability,Shelf life

Heating/cooling function 

→Suitable Products:

Face cream

Body lotion

Sunscreen

Cosmetic cream

Foundation

Serum

Hair conditioner

Ointment

→Advantages:

✔ Higher product quality
✔ Vacuum protection (vacuum type): The vacuum environment removes air bubbles, prevents oxidation, and extends the product's shelf life.
✔ Flexible operation: Variable frequency speed control adapts to formulations of different viscosities; optional vacuum feeding avoids dust emissions.
✔ Higher product stability
