Date Dec. 14, 1995A vacuum vessel for continuous or semicontinuous treatment of fatty oils in connection with deodorization includes spaces through which the oil which is to be treated is brought to pass. The vessel also contains U-tubes used to heat or cool the oil and perforated pipes arranged at the bottom of the vessel. Through these pipes stripping gas is led into the oil. The vacuum vessel is connected to a vacuum source. According to the invention the vessel has the form of a container with a mainly rectangular bottom with partitions parallel to a long side of the container. These partitions delimit channels connected in series through which the oil passes. The bottom of a first channel as seen in the direction of flow is arranged on a higher level than the second channel seen in the direction of flow such that the oil is forced to pass through the vessel by gravity. The vacuum vessel has a low height in relation to the length of its sides.
