The central component of the wort aeration unit is a three-dimensional dissolution database. It controls the air flow rate in proportion to setpoint, wort pressure and flow velocity. In a static mixer developed specially for the aeration of wort the necessary quantity of oxygen in the air is dissolved in a controlled process. The dissolution path is limited to the length of the mixer, i.e. there is practically no dissolution in the subsequent pipe system. A product trap integrated into the line prevents wort from entering the air system.
Design
- Function-tested units are preassembled on a compact baseframe
- Use of VARIVENT® components for highest hygienic standard and best CIP-ability
- Individual units can be upgraded from the simplest to the most powerful version without welding and cutting work
- Capacity adjustment by exchanging parts with detachable connections within the range of nominal widths between DN 50 - DN 125
Alternative I
- without downstream pressure-keeping valve at a wort pressure of ≥ 1.5 bar G
Alternative II
- with downstream pressure-keeping valve for achieving a minimum pressure of 1.5 bar G.
