알파라발 Hermetic 디자인

Hermetic 디자인이 적용된 원심분리기는 제품을 세심하게 다루어 최상의 제품 품질을 지원합니다. 전단력과 전력 소비를 줄이며 산소 포집을 방지합니다. 공정 유체에 공기가 없는 환경은 더 나은 공정 제어와 최적의 공정 조건을 보장합니다. Hermetic Design을 사용하면 볼 내부의 유리한 유체 역학으로 인해 분리기의 에너지 소비가 줄어듭니다. 이 디자인은 또한 CIP(Cleaning-in-place) 주기를 최적화하여 CIP 유체가 제품에 닿는 모든 부품과 접촉하도록 보장합니다.

Where to use it

In the dairy, food, beverage, brewery, biotechnology, pharmaceutical and vegetable oil industries.


How Hermetic Design works

From the separator’s airtight bottom-fed inlet zone, feed enters the separator through a closed hollow spindle, which prevents oxygen pickup. The bowl with its carefully engineered outlets effectively eliminates any air-liquid interface inside the separator. Low shear in the feed inlet zone secures gentle product acceleration into the separator, and low shear in the bowl ensures gentle product handling during the separation process. This minimizes product loss and increases separation efficiency. Hermetic Design, for instance, prevents the destruction of the cell walls for biotech processes and emulsification in dairy and edible oil processes.
