Jucie Aerator


The Juice Aerator is used for the continuous and highly accurate injection of oxygen or sterile air into fruit juice. For yeast reproduction and growth and consistent fermentation, the specified oxygen content needs to be exactly reached.


The solubility of oxygen in fruit juice depends on the temperature. The colder the liquid, the better is the oxygen solubility. Therefore, aeration is done after cooling of the juice. The amount of oxygen or sterile air to be added to the juice depends on various factors, e. g. sugar content, type of yeast and the desired final product characteristics. The Juice Aerator can be designed for manual or fully automated operation. Automated systems measure and control the O2 content of the fruit juice with highest precision with an optical OXYTRANS sensor made by Centec. Centec have decades of experience in the development and manufacturing of own precision instruments for O2 control. Based on oxygen and flow measurement, the amount of oxygen injected is precisely adjusted to match the measured juice flow. For O2 injection the Juice Aerator has a specifically designed Vortex-Venturi injector that feeds oxygen in a very large number of very fine bubbles directly into the product stream. Due to pressure and turbulent flow, the oxygen dissolves completely and absolutely homogeneously in a very short time. At the end of the dissolving path a control valve can be installed to keep the pressure in the system constant and above the saturation pressure. The Juice Aerator is equipped with a sterile filter system to sterilize the incoming gas.
