Vacuum de-aeration unit for liquid to pasty products
In industries like pharmaceuticals, cosmetics, and food processing, maintaining product integrity during filling and packaging is crucial. Air bubbles in products can lead to inaccuracies and degradation, affecting both quality and stability.

Continuous de-aeration for consistent quality
The PUC EVA vacuum de-aeration unit by Probst und Class ensures continuous de-aeration of liquid to pasty products. It operates by feeding the product into a vacuum vessel, where it flows down the inner walls in a thin film or droplet form. This process reduces the diffusion path and effectively removes gases like oxygen, without changing the product’s temperature. The unit is available in different sizes to accommodate varying capacities up to 10,000 kg/h. Its automated operation and easy maintenance make it suitable for applications in the pharmaceutical, chemical, cosmetics, and food industries.
