Processing of liquid products often incorporates air and unwanted gases into the product. These gases normally cause problems such as oxidation, discoloration, inconsistency, bad smell and filling difficulties. The PerMix PDA series Vacuum Deaerator is a totally compact sanitary device designed for the continuous automatic removal of air or other occluded gases from any type of liquid or paste, by means of vacuum. This extends shelf life, stops oxidation of products, and will present with a better appearance after packaging. Some other areas that will be improved are colors will be held longer, aromas will be intensified, and the HACCP & SQF procedures will be greatly helped in this step.
