To remove selectively particularly sugar from nonalcoholic or alcoholic beverages, first the sugar is either carried away in the permeate in a membrane separation unit (2) by suitable choice of membrane (4) or is retained in the retentate. Afterward, the sugar is removed from the permeate or from the retentate with the help of a device (5) for substance removal or substance conversion. Next the substances remaining in the permeate or in the retentate after the removal of the sugar are fed back into the process or the final product. With the process according to the invention, a high selectivity and an improvement in quality of the final product with high economic efficiency of the unit is achieved (FIG. 1).

Process for selective removal of sugar from beverages

Process for the production of cloudy juice which is clouding-stable

For extraction of juice from fruits and vegetables a process is used in which first the raw material is crushed in a crushing device (1) and separated in a screening device (2) from the solid components, then liquefied by physical cell breakdown, and the raw juice is clarified in a filtration device (9). In this connection, device (8, 27, 32) for the physical cell breakdown can be integrated into filtration device (9) or into filtration module (13) of a membrane filtration device.

Process for aftertreatment of liquids, in particular clarified juice,

A process and apparatus for extracting a liquid from a filtered residual substance, such as retentate resulting from an ultrafiltration during fining or clarification of raw juice from agricultural products. The residues are mixed with the expressed pomace in a separate processing and the mixture is subjected to a further juice extraction.

Process for extracting of liquid from a residual substance

A process and apparatus is disclosed for degassing liquids, particularly raw juices from fruits and berries. The liquid which is to be clarified or liquid residues remaining after clarification are subjected to degassing while circulating in a processing installation. A vacuum producing device is provided through which the liquids are circulated.
