An agitator is a device designed to mix, emulsify, homogenise or disperse liquids and semi-solids. Due to their design and functionality, agitator mixers are widely used in various industries.

The agitator-mixer consists of an electric motor, a drive and a mixing element (blade, propeller, turbine) that rotates inside the tank. The movement of the mixing element creates a hydrodynamic flow that ensures uniform mixing of the components.

The process can take place through various mechanisms:

1. Mechanical mixing: Blades or propellers create turbulent flow in the liquid.
2. Dispersion: The particles are divided into smaller fractions.
3. Emulsification: Mixing two phases, such as water and oil, to form an emulsion.
4. Homogenisation: Reducing the particle size to produce a homogeneous product.

Areas of application

1. Food industry:
   • Mixing sauces, creams, yoghurts, syrups.
   • Preparation of emulsions (e.g. mayonnaise).
2. Pharmaceuticals:
   • Homogenisation of creams, ointments, suspensions.
   • Preparation of sterile solutions.
3. Cosmetics industry:
   • Mixing creams, shampoos, gels.
   • Create emulsions and gel-like textures.
4. Chemical industry:
   • Dispersion of paints, varnishes and adhesives.
   • Mixing aggressive and viscous liquids.
5. Agriculture:
   • Preparation of feed mixtures.
   • Dissolving fertilisers and pesticides.

Features of the agitator mixers

1. Type of mixing element:
   • Paddle stirrers for viscous liquids.
   • Turbine agitators for low-viscosity applications.
   • Propeller agitators to create a strong flow.
2. Materials of execution:
   • Stainless steel (AISI 304/316) for food, pharmaceutical and chemical products.
   • Corrosion-resistant coatings for use with aggressive substances.
3. Type of drive:
   • Electric: Ensures high performance and stability.
   • Pneumatic: For use in explosive atmospheres.
4. Rotation speed:
   The adjustable speed allows the agitator to be adapted to different processes (homogenisation, mixing, emulsification).
5. Possibility of integration:
   Some models support automation and integration into production lines.

What is the right mixer for you?

1. Process type:
   Determine whether the stirrer is used for mixing, emulsifying, dispersing or homogenising.
2. Fluid characteristics:
   • Viscosity: Consider whether the medium is liquid, viscous, or paste-like.
   • Sensitivity: Whether the structure of the product needs to be preserved.
3. Tank volume:
   Choose the model with the right shaft length and power for your tank.
4. Materials:
   Select the material of the body and mixing element depending on the medium (food, aggressive or sterile liquids).
5. Compatible with CIP/SIP systems:
   For pharmaceuticals and food processing, make sure the equipment supports automatic cleaning.
6. Rotation speed:
   Choose a model with adjustable speed if you need to perform different tasks.
7. Energy consumption:
   Consider equipment efficiency to reduce energy costs.
