Abstract: The invention relates to a process for the preparation of milk and milk powders having a long storage life utilizing techniques which are known per se. To that end, a milk liquid is prepared, which is evaporated, and a fat fraction is added to the milk liquid in one or more effects of the evaporator. This process is particularly suitable for the preparation of a milk having a long storage life, in which unsaturated fatty acid chains are present.

Abstract: A double flow rate meter (1) and an apparatus for automatically feeding animals with liquid food which utilizes the flow meter (1) for establishing the amount of food consumed is disclosed. The flow rate meter (1) comprises at least two circular flow passages (2, 20), each containing a ball (11, 12) constrained to be propelled through the relevant channel by fluid proportionally to the flow velocity of the fluid. The balls (11, 12) pass respective sensors (15, 16) in the flow passages. Each flow passage (11, 12) has its own inlet conduit (3, 5) and respective outlet conduit (21, 22), the outlet conduits merging into a single, common outlet conduit (4) leading to a nipple (37) or the like food dispensing means. The flow rate meter enables controlled feeding of an animal with liquid food while medicine or another compound can be administered simultaneously and proportionally to the supplied food.

Abstract: Dry powder mix is mixed with water in accurate amounts on demand, the water and powder pass through an axial passage of a mixing rotor and must pass radially outward in a mixing bowl through a narrow gap to a tangential discharge opening. Demand is determined by startup and continuous operation level sensors arranged to maintain accurate and limited levels of mixed product in the freezing cylinder.
