Decanters are vessels and machines used to separate liquids from solids, or to separate two immiscible liquids, by gravity or centrifugal force. In food processing, decanter centrifuges continuously separate olive oil from paste, clarify juices and dewater sludges, handling large throughputs with enclosed, hygienic designs that protect product from recontamination. In wine service, simple glass decanters aerate the wine and leave sediment behind in the bottle. Both uses rely on density differences, and cleanability is essential for food-grade operation, with tool-free disassembly and sanitary finishes standard on industrial models.
