The invention relates to a method for spray drying perishable liquid products such as milk products. The exhaust gas from the spray dryer is passed through a gas scrubber in which at least part of the liquid product to be dried is used as washing liquid before spraying it into the spray drying chamber of the spray dryer. Prior to passing it into the gas scrubber the washing liquid is heated to a pasteurizing temperature by suitable heating means. These heating means may, for example, be adapted to inject hot steam into the flow of washing liquid, or the heating means may be in the form of an evaporator connected to the spray dryer at the upstream side thereof.

Method for spray drying liquid products

A centrifugal separator for separating liquid and gas comprising a container having a cylindrical wall with a vertical axis and bottom wall defining a central inner surface part having a domed or convex shape, and an annular channel defined at the lower part of the cylindrical wall. The mixture of liquid and gas is introduced into the container and caused to rotate about the said vertical axis. Gas is discharged from the container through a gas discharge tube arranged centrally in the upper part of the container, and liquid is discharged from the annular channel through one or more liquid discharge conduits being connected to a level control device for securing a liquid level within predetermined limits in the channel or groove.
