Súhrn: Solid-liquid separations in food processing constitute a series of important unit operations that are applied in tradi¬tional as well as in innovative processes, and that can play an important role in production, quality and even preservation of many food products. Separation techniques are involved in a great number of processing industries and represent, in many cases, the everyday problem of a practicing engineer. This article reviews general operating principles of solid-liquid separations, under a general fluid mechanics principle, and analyse their main applications in the food industry, emphasizing the basic concept of food quality and preservation.
