In-Tank Atmospheric Deaeration with Reversible Homogenizer

The Greerco Reversible Homogenizer from Chemineer can produce high quality shampoos, gels, creams, and lotions – without the need for vacuum processing vessels or in-line vacuum deaeration devices.

Designed with atmospheric deaeration and flow-direction control, the Greerco Homogenizer is effective across a wide viscosity range, including both liquid and powder components, and has the flexibility to consistently produce bubble-free end-products in different batch sizes.

When the powder or liquid addition phase of the process is complete, the Homogenizer is switched to run briefly at full speed to fully homogenize the batch and completely disperse any remaining agglomerates.

At this point in the manufacturing, when the deflector plate is located precisely at the surface level of the liquid-at-rest, deaeration begins.
The operator adjusts the speed of the homogenizer to provide a smooth, laminar, non-splashing flow that moves 360 degrees away from the circular deflector plate. Entrained air bubbles are drawn up from the bottom of the batch and distributed gently at the surface of the liquid. After approximately 30 minutes of atmospheric pressure deaeration (depending on viscosity), the batch is fully deaerated.

In addition to the Greerco Homogenizer, Chemineer also designs and builds the Greerco Pipeline Mixer for use in continuous in-line homogenization, particle size reduction or dispersion, and also the Greerco Colloid Mill, which allows the user to easily modify the shear rate in batch, batch-continuous or in-line applications.
