The VDM
Vacuum Drum Mixer

The Vacuum Drum Mixer is a great solution for customers who prefer to mix their product directly in the shipping container and under vacuum. The VDM is ideal for mixing or re-homogenizing viscous products where deaeration is critical and transferring to a vacuum rated tank is not practical.

Drum/bucket is secured on steel platform with mounting bracket and tightening strap
Vacuum bell lowers and vacuum is applied
Single start/stop button runs entire process
Two sight glasses provide visual access during processing
Electric switch monitors level of vacuum applied
Control panel automates vacuum/mixing process with easy-to-set timers

How Does Vacuum Drum Mixing Work?

Vacuum drum mixing is ideal for handling viscous products directly in their shipping containers, such as drums or buckets. This method is particularly beneficial when transferring to a vacuum-rated tank is impractical, as it combines mixing and deaeration in a single, streamlined process. Here’s how it works:

1. Container Securing

The drum or bucket is placed on a robust steel platform and secured using a mounting bracket and tightening strap.

2. Vacuum Application

A vacuum bell is lowered over the container, creating an airtight seal. Vacuum is then applied to remove air, preventing oxidation and ensuring thorough mixing without air pockets.

3. Mixing Process

With the vacuum in place, the mixing process begins. A single start/stop button controls the entire operation, automating the process through an easy-to-use control panel.

4. Monitoring

Two sight glasses provide visual access to the product during mixing, while an electronic vacuum switch monitors the vacuum level to maintain optimal conditions.

Common Applications for Vacuum Drum Mixers

Vacuum drum mixers are used in various industries and applications where thorough mixing and deaeration are essential. The VDM’s ability to mix directly in the shipping container eliminates the need for intermediate transfer, which saves time and reduces handling. Common applications include:

Adhesives and Sealants

Mixing viscous materials where air removal is critical to prevent air bubbles and ensure product consistency.

Cosmetics and Personal Care Products

Homogenizing creams, lotions, and gels under vacuum to achieve a smooth, aeration-free texture.

Pharmaceuticals

Mixing ointments, gels, and other viscous formulations to ensure uniformity and prevent contamination by air.

Paints, Inks, and Coatings

Re-homogenizing materials to maintain consistency and remove air that could cause defects or inconsistencies.

Food and Beverage

Preparing thick pastes, gels, or semi-solid products where maintaining a vacuum is necessary for quality and shelf-life.

Chemicals

Blending reactive or viscous chemicals in a controlled, vacuum environment to ensure safety and uniform mixing.
