Vacuum Mixing

Mixing under vacuum offers several advantages, including the elimination of unsightly voids in the final product, enhanced dispersion quality, effective degassing, improved drying at lower temperatures, and the ability to add raw materials sub-surface. By optimizing vacuum mixing techniques, you can maximize these benefits.

Why Vacuum Mixing?

Vacuum refers to a space where the pressure is lower than atmospheric pressure, meaning it contains fewer gas molecules per unit volume compared to ambient air.

Vacuum environments achieve various mixing goals depending on the application. For instance, in coatings, personal care products, or molded composites, a void-free mixture enhances both aesthetics and the strength of engineered parts. In other cases, vacuum is used to remove oxygen, preventing the decomposition of sensitive ingredients, avoiding unwanted chemical reactions, and inhibiting microbial growth. For example, minimizing oxygen in beverages helps maintain consistent quality throughout their shelf life.

Additionally, vacuum mixing improves product handling and performance. It helps prevent defects in syringe filling or printing of gels and pastes. Moreover, vacuum mixing accelerates drying processes and allows for drying at lower temperatures, which is ideal for heat-sensitive materials, reducing the risk of thermal degradation.
