  • Ultrafiltration is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane.

Thus, the nanofiltration process can only be used in a cross-flow mode of filtration, i.e. in the presence of a flow of fluid moving along the membrane surface and jetting the discharge of the contamination.

  • cavitation processing leads to a significant decrease of the content of organic impurities, fluorescing both in the UV and visible ranges, in the treated alcohol as well as in the alcohol solutions prepared from it.
  • Cavitation treatment in two-pass systems particularly in a high pressure hydrodynamic cavitation device, resulted in the removal of additional impurities with a fluorescence maximum of 400-450 nm. It is believed that the mechanism of action of cavitation treatment on organic impurities in aqueous alcohol solutions involves the breaking of double bonds in the carbon chain and shortening of the conjugated system, leading to a decrease in the absorption of light in the optical UV range and a decrease in fluorescence emission.
  • Cavitation processing of ethanol significantly reduces the content of mono- and polyaromatic impurity compounds, i.e., derivatives of benzene, phenol, tyrosine, tryptophan, benzaldehyde, and others. Such reduction of impurities greatly improves the organoleptic characteristics of alcohol-based beverages.
  • Alcoholic beverages based on an aqueous solution of alcohol may contain impurities such as Acetaldehyde and/or Acetal, Benzene, Methanol,
  • Fusel Oils as Isobutyl, Isoamyl and active Amyl, Non Volatile Matter, Heavy Metals and others.
  • the presence of these impurities in alcohol-containing beverages reduces their flavor and aroma qualities.
  • Cavitation treatment of alcohol beverages and ethanol causes destruction of impurities, decreases the concentration of Acetaldehyde, Acetal, Benzene, Methanol, Fusel Oils,
  • the inventive beverage fluid treatment system 1 0’ of the second preferred embodiment functions in a manner similar to the first preferred embodiment.
  • An alcoholic beverage is poured into the vessel 1 2 and the processing apparatus 14’ is inserted into the vessel 1 2, with the tube assembly 16’ extending toward the bottom 1 2b of the vessel 1 2.
  • the top of the processing apparatus 14’ (containing the pump 1 8’ and motor 20’) covers the open top 1 2a of the vessel 1 2 so as to enclose the beverage fluid.
  • the motor 20’ activates the pump 1 8’ so that beverage fluid is drawn from the vessel 1 2 into the intake tube 22’.
  • the pump 1 8’ then forces the beverage fluid from the intake tube 22’ into the cavitation tube 24’. Cavitation occurs as described above.

Abstract

L'invention concerne un système et un procédé pour la purification de fluides de boisson, principalement des boissons alcoolisées, sur la base de l'action d'un traitement de cavitation hydrodynamique de contaminants microbiologiques et chimiques, de microparticules et de particules colloïdales. Le système est un système de lots avec un seul récipient ayant un tube d'extraction et un tube de décharge s'étendant dans le même réservoir de fluide. Le fluide est aspiré à travers le tube d'extraction et passe de force par le tube de décharge. Le tube de décharge contient des éléments de cavitation dispersés sur sa longueur pour générer une cavitation hydrodynamique dans le fluide lorsqu'il est pompé à travers celui-ci. Le fluide de décharge est mélangé avec le fluide déjà dans le récipient et est ré-aspiré à travers le tube d'extraction dans un traitement de lots continu.
