The document discusses Tetra Pak's range of aroma recovery systems, including the Tetra Alvac PL, CD, CS, and aroma rectification column. The Tetra Alvac systems recover aroma from vapors produced during beverage processing through condensation and separation of aroma concentrates. The aroma rectification column further separates and purifies aromas through distillation and reflux.
