Working Principle of a Deaerator System

The deaerator utilizes a low-pressure vacuum chamber where pre-heated liquid is sprayed into a thin layer. The reduction in pressure causes dissolved gases to separate instantly from the liquid.

Depending on the process requirements, the deaeration cycle may include

    Product pre-heating to optimum deaeration temperature

    Atomized spraying into the vacuum chamber

    Flash evaporation and gas release

    Condensation recovery of volatile aroma compounds

    Discharge pumping under low-NPSH conditions
