Abstract
The invention relates to a method and a device in a steam injector. The steam injector is of the type which includes an injector housing with an inlet for steam and an inlet for the product which is to be treated. In the injector housing there is also an outlet for the ready-treated product. In the injector the steam is brought together with the product. The device includes a throttle washer which is placed immediately after the product outlet. The throttle washer entails that the pressure is raised immediately before the product leaves the injector. The pressure increase entails an improved steam distribution in the product and that the risk of sedimentation in the product is counteracted. The device also entails that disturbing noise that may occur in the injector is considerably reduced.
