Apparatus for separating the liquid occurring substances with a density which is close density of the liquid, in particular for the extraction of fat and protein substances from the process water from the food industry

摘要

Device for the separation of substances contained in a liquid, when such substances exhibit a density, which is close to the density of the liquid, the device preferably being used for the extraction of fat and protein matters from process water in the food industry. By in vertical direction accelerating and the flow of a liquid containing particles with higher or lower density than the liquid, in which the particles are suspended, and at the same time change the direction of flow, particles heavier than the suspending liquid can settle on the bottom of a vessel (1), from where they can be drawn off, and particles lighter than the suspending liquid are collected on the surface, from where they can be removed by for example skimming. The acceleration and retardation are brought about by changes of areas in a vessel with a guided flow and where the direction of flow, which is substantially vertical, is turned by about 180 DEG at several occasions.
