Abstract: A method in which the storage and processing of the liquid to be dealcoholized is carried out in a dealcoholization circuit in a non-oxidizing atmosphere, partial diafiltration of this un-diluted liquid in a reverse osmosis module is carried out, an exchange of water takes place to compensate partially for the loss of volume due to the separation of the permeate, by the addition of demineralized water which is totally free from any trace of chlorine, and deaerated and natural or synthetic ingredients, not extracted from the original liquid by thermic treatment, are added to the residue. In order to obtain complete desalcoholization, preconcentration of the original liquid to be dealcoholized is carried out at a temperature of between 10.degree. and 15.degree. C. and during processing, at least one concentration, one dialfiltration and one dilution are carried out alternately. This method is mainly used to process wine, beer and cider and allows them to retain their required standards of quality and taste.

Abstract: Apparatus particularly for agglomerating particles of different products. A rotatable drum, which has a wall which defines a cylinder and a cylinder void, is mounted on a frame in a horizontal or inclined position. The apparatus includes provision for rotating the cylinder in one direction thereby defining ascending and descending halves of the cylinder. A first part of the cylinder receives particles of a product and has means, such as projecting elements, to rotate the particles for forming a vortex of particles about an axis within the ascending half of the cylinder void such that the axis of the vortex is displaced from and substantially parallel to a central longitudinal axis of the cylinder.

Abstract: In an inclined rotary drum, a vortex of a particulate main product is formed about an inclined axis, an agglomerating agent is sprayed onto the vortex from outside and a particulate secondary product is distributed in the vortex from inside.
