An agitator is a machine for stirring liquids or solids, as used in particular in the industrial production of foodstuffs, pharmaceuticals, cosmetics, paints, varnishes, adhesives and other liquids and mixtures.

An agitator consists of a drive, an agitator shaft and an agitator element. These are adjusted to the size of the Stirring tank designed. The chemical and material-specific characteristics of the medium to be stirred and the stirring task also influence the properties of the agitator. These properties include

• Speed and torque of the drive,
• Size of the agitator shaft,
• Number, shape and size of the agitators,
• General choice of materials (ATEX protection, food-safe, waterproof, etc.).

Stirring tasks performed by an agitator are Homogenize, Dispersing liquid-liquid, Dispersing gas-liquid, Heat transfer, Suspend and Mixing solids.

The agitator is selected according to the stirring task. The Flow profiles and Flow types of the different stirring elements plays a role. These must be suitable for the mixing task.

The attachment to the Stirring container is carried out via a traverse or a cover. Particular operating convenience and ease of work is provided by a Agitator with lift with automatic lifting mechanism for the agitator.

Agitators are often complemented by upstream or downstream components. For example, dosing pumps, dispensing nozzles, scales, etc. This turns individual agitators into Complete systems.
