Abstract: Proteins are obtained from soy milk by concentrating the soy milk while increasing the dry matter content. A water-soluble organic solvent is added to the soy milk to form an organic-aqueous suspension in such a way that a shift in the solubility equilibrium occurs due to the addition of the organic solvent and a displacement extraction takes place. The volume of added organic solvent in step iii is selected such that the content of organic solvent of the organic-aqueous suspension is at least 15% by volume. The suspension is adjusted to a pH value of less than pH=7, forming at least one protein phase. The protein phase, with a residual oil content of less than 5 wt. %, based on the dry substance content of the protein phase, is separated from the suspension.

Abstract: A centrifuge includes a rotatable rotor and an assembly that is stationary during operation. The rotatable rotor is rotatably mounted in or on the stationary assembly by one or more mounting devices. The rotatable rotor has a rotatable drum and a drive element for rotating the drum as well as one or more electrical loads located on or in the rotor. The centrifuge includes at least one battery is also located on or in the rotor in order to supply the at least one load or the plurality of loads with electrical power. The load can include a data memory in the rotor or on the rotor. At least one actuator is provided as the at least one load.

Abstract: A method for influencing the pulp content of a fruit or citrus juice. The method steps include: continuously purifying the juice of a pulp phase in a centrifugal field of a separator, the pulp being discharged from a drum of the separator through a pulp discharge line; measuring a density of the discharged pulp phase by a density flow-through measuring device; and, controlling a controllable device in accordance with a density measurement by the density flow-through measuring device thereby influencing the density of the pulp phase.

Abstract: A method for clarifying a wine sediment. The method steps include providing a solid-wall worm centrifuge, clarifying the wine sediment in the centrifuge by forming a solid phase and a liquid phase, and fining the sediment by adding a fining agent at one or both of before and during the centrifugal clarification.

Abstract: A method for extracting fruit or vegetable juices, the steps comprising: grinding one of fruits and vegetables to obtain a mash; adding peel components to the mash; and juicing the mash.

Abstract: According to a method for extracting fruit or vegetable juices, the fruit is reduced in order to produce mash. The mash obtained from said fruit is then juiced. According to the invention, peel components are added to a/the mash before juicing. Stalk, core and/or peel components are preferably separated from the mash produced from the reduced fruit and the peel components and/or other materials are fed back into a/the mash before said mash is juiced.
