Abstract: The use of encapsulated oil for the preparation of a dough. The encapsulated oil comprises an inner core of oil encapsulated in an outer shell of cross-linked protein, wherein the encapsulated oil comprises at least 80% by weight oil. The dough is formed by mixing 0.5 to 40% of the encapsulated oil with other ingredients.

Abstract: The invention concerns a vacuum drainage system with a vacuum line connected with a vacuum source, in which a vacuum valve (10) is arranged between a collection point collecting accumulated waste water and the vacuum source that exhibits a housing, which exhibits a vacuum side housing part (53) added to the vacuum side of the vacuum line as well as a converged housing (51) part added to the converge-sized vacuum line, whereby preferably a flexible, especially tube-like first element (12) of the vacuum valve is arranged in the housing, admittable with pressure between the housing and available space (48) of the first element and with the closed vacuum valve, the first element is pulled together by caulk running preferably linear or lamellar to the longitudinal axis of the area (18,19) of the first element, is proposed, that a check valve (64) blocking the back flush of waste water in the vacuum-sided cabinet section (53) of the vacuum valve (10).

Abstract: A pinch-type interface valve for vacuum sewer systems. The interface valve includes a valve chamber and therein a tube-like elastic element. The elastic element has a lateral seal section with seal strips. The seal strips are pressed against each other and tightened when the elastic element is axially compressed. The elastic element is expanded and the seal strips are pulled from each other when vacuum is transmitted into the valve chamber.

Abstract: Arrangement and method for the prevention of water entering a pneumatic controller of a vacuum sewer system through a breather line. The proposed pneumatic controller is a non-bleeding controller preventing continuous flow of air from the breather line through the controller. The volume of breather air entering the controller during an evacuation cycle is smaller than the volume of a water trap provided in the breather line. The water trap removes water from the breather air before it enters the controller.
