Centrifugal defoaming machines and stirring defoaming machines are two common types of equipment used for defoaming materials. Many people are unsure whether to choose a centrifugal defoaming machine or a stirring defoaming machine when defoaming materials. In this article, the SIENOX editor will discuss the differences between centrifugal defoaming machines and stirring defoaming machines to help everyone make informed choices when selecting defoaming machines.

1. Different Principles:

Centrifugal defoaming machines use centrifugal force to defoam, separating heavier and lighter materials based on the centrifugal force of the material and air bubbles.

Stirring defoaming machines employ a combination of rotation and revolution to defoam materials. They utilize centrifugal force for defoaming and shear force generated by the rotation and revolution for stirring. Some people refer to this stirring principle as planetary defoaming machines.

2. Different Functions:

Centrifugal defoaming machines are commonly used for single-material defoaming, such as adhesives, resins, and inks. They are typically equipped with fixtures such as syringes, needle tubes, or dispensing tubes. Hence, some people also refer to them as syringe defoaming machines.

Stirring defoaming machines are often used for mixed defoaming of multiple materials. They are suitable for achieving consistent density after mixing materials with different densities and viscosities. These machines are commonly used for fluid or semi-fluid materials such as UV adhesives, epoxy resins, silicones, and gels.

3. Different Costs:

In terms of cost, centrifugal defoaming machines are relatively less expensive compared to stirring defoaming machines. Stirring defoaming machines have a more complex principle and more powerful functions. Additionally, they can be customized with temperature control functions according to the specific requirements of the application, such as cryogenic stirring defoaming machines, resulting in higher overall costs.

4. Different Capacities:

Centrifugal defoaming machines mainly use needle tubes for defoaming, which typically have smaller capacities. Stirring defoaming machines usually use stirring cups for defoaming, which generally have larger capacities. However, the specific capacity depends on the size of the chosen defoaming machine and the type of fixture selected.

Centrifugal defoaming machines and stirring defoaming machines differ in principles, functions, costs, and capacities. When selecting a defoaming machine, it is essential to consider the characteristics of the materials and the defoaming requirements to determine the appropriate equipment.
