Wine is a cultural asset. In order to keep alive the ancient tradition, people increasingly use centrifugal separation technology for modern and economic wine production. During the whole winemaking operation, clarification plays an important role. Thus an efficient clarification system often determines the taste, aroma, and character of the wine and therefore its overall quality and its market value.

In 1911, Gustav Otto, son of the inventor of the Otto engine, founded "Gustav Otto Flugmaschinen-Werke" in Munich. On March 7, 1916, his company merged with "Bayerische Flugzeugwerke", which is the official foundation of "Bayerische Motorenwerke" BMW.

In 1920, Gustav Otto introduced and sold a motor-assisted bicycle named "Flottweg" and subsequently built in his new company "Otto Werke G.M.B.H München". Dr. Georg Bruckmayer bought "Otto Werke München" in 1932 and renamed the company "Flottweg Motoren-Werke". This new company manufactured aircraft engines, motor-assisted bicycles and motorbikes.

In 1943, the company relocated to Vilsbiburg. After World War II, the company manufactured precision parts for the printing industry. To promote a second business, the company started to develop the first centrifuges in the early 1950's. 1956 saw the first Flottweg Decanter, Type Z1, delivered to BASF AG, Ludwigshafen followed by the High Speed Decanter in 1964.

The 3-phase decanter emerged in 1971 followed by the Flottweg belt press in 1984, the Flottweg Sedicanter in 1993 and the Flottweg Sorticanter in 1995. 1998 Brought with it the start of the Flottweg C-type disc stack centrifuges. By 2011, the 8000th Flottweg Decanter had been processed.
The must is fed through a stationary pipe into the feed zone located in the center of the scroll. The product is then accel­ erated circumferentially and delivered through distribution ports into the bowl. The bowl has a cylindrical/conical shape and rotates at a pre­set speed optimal for the application. The must rotates with the bowl at the operating speed and forms a concentric layer on the bowl wall. The solids con tained in the must are deposited against the bowl wall by centrifugal force.

The scroll rotates at a slightly different speed than the bowl and conveys the deposited solids toward the conical end of the bowl. This differential speed determines the residence time of the solids in the bowl. Settled solids are ejected through ports at the conical end of the bowl.
Must is discharged via an adjustable impeller. This permits quick and precise adjustment of the pond depth during oper­ ation to accommodate changing conditions without switch­ ing off the decanter.

Since the must is discharged off the decanter under press­ ure, a discharge pump is not necessary. The clarified must normally contains solids of <1% v/v. Subsequent flotation allows the elimination of trub particles which cannot be sep­ arated from the must because of the small density differ­ ence.Decanters may also be used for treatment of flotation trub or wine recovery from tank bottom after fermentation.
