Stirring defoaming machines are widely used for mixing, stirring and defoaming of various materials, which can efficiently remove nano-scale bubbles with powerful functions. However, many users still do not understand its working principle during operation. This article from Sinos stirring defoaming machine team will introduce the working principle and working process of stirring defoaming machines.

1. Revolution and Rotation

Stirring defoaming machines generate stirring effects through revolution and rotation. Revolution means that the whole container of the stirring defoaming machine rotates around the central axis of the equipment, while rotation refers to the stirring cup spinning around its own axis. Combined, these two movements create complex three-dimensional stirring motion.

2. Shearing Force

Driven by revolution and rotation, the mixer generates strong shearing force. Shearing force refers to cutting and sliding interaction between two objects in relative motion. Inside the stirring defoaming machine, liquids are cut and mixed with the movement of the stirring cup to achieve uniform mixing. Thanks to shearing force, the machine can handle liquids of different viscosities, including high-viscosity colloids.

3. Vacuum Pump

Stirring defoaming machines are normally equipped with vacuum pumps. The vacuum pump extracts air and gas inside the mixing container to create a vacuum environment. Vacuum helps remove microbubbles in liquids more efficiently and improves defoaming performance. This is critical for manufacturing high-quality and high-transparency products, as tiny bubbles may cause uneven surfaces and impair product appearance and quality.

4. Defoaming Process

With the assistance of stirring shearing force and vacuum environment, stirring defoaming machines can effectively eliminate bubbles in liquids, especially nano-scale microbubbles. This physical treatment separates bubbles from liquids based on mechanical principles, thus improving product quality and performance.

In general, stirring defoaming machines combine multiple mechanisms including revolution, rotation, shearing force and vacuum pumps to realize high-efficiency stirring and defoaming. It has become indispensable equipment in various industrial production and widely used in chemical, pharmaceutical, food and other industries, providing reliable technical support for manufacturing processes.
