Definitions

  • the present invention relates to the field of wine industry and may be, according to the International Patent Classification (IPC 7 ), classified in C12G1/02.
  • IPC 7 International Patent Classification
  • the technical problem to be solved is a design of new apparatus and method for cold thickening of must without saccharose addition.
  • the state of the art includes the technique of thickening the must by boiling it at 100°C and under the atmospheric pressure.
  • the deficiency of this process is the modification of organoleptic features of wines thus prepared, such as a caramel scent and the like.
  • the second process used is boiling at lower pressure, the vapor being vacuumed by vacuum pumps, but I don't know whether this process is used in the Republic of Croatia.
  • the essence of the invention is the continuous thickening of must at lower temperatures.
  • the apparatus allows the must thickening even at temperatures below 15°C.
  • the optimal working regime ranges from 20°C to 50°C.
  • the already constructed and tested apparatus of a volume less than 100 dm 3 (0,1 m 3 ), and nominal electromotive driving force of less than 3kW, allows 250 liters of water to be separated from the treated must within 24 hours, without any necessity of the human control.
  • thickened must may increase for 2% the amount of the basic sugar of 2100 liters of the same must (e.g. from 17%> it can be increased to 19%>).
  • a significant additional characteristic of the apparatus is its relatively low price, being such owing to the possibility of building in it serially produced machines and fittings.
  • FIG. 1 Schematic representation of the apparatus
  • Fig. 2 Vacuum-column (axial cross-section)
  • Fig. 3 Bottom of the vacuum-column (transversal cross-section)
  • Fig. 1 shows the way in which fresh must (1) is sucked in a vacuum-column (5) through a suction pipe (2), a filter (3) and a level regulator.
  • a circulation pump 13
  • a divisional fitting with overflow valve 14
  • the main stream flows through a must heater (15) and tangentially set nozzle (16) stream into a vacuum-column (5), while a smaller portion (approx. 5%), depending of the must thickness, flows, through an overflow valve (14) to a container (17).
  • the vacuum pump (11) is put into operation at intervals, depending on the accumulated condensate (9) and the increase of the pressure in the vacuum system.
  • Fig. 2 and 3 show the vacuum column (5) that sucks the flowing must through a nozzle (16) which through a directed narrow and flat slot (25), in a tangential flow a little bit downwards and in a high velocity showers the inner cylindrical wall of the column, so that the must in a tin layer spirally flows towards the bottom of the column, releasing the vapor and partially retaining its kinetic energy, which is, at the bottom, partially transformed, by spiral ribs (21), into potential energy, to facilitate its flow towards circulation pump (13) and to decrease the cavitation on the pump rotor.
  • the level regulator (4) spills the fresh must (1) into a pot (20) and doses it, through lateral openings (26), into the circular flow system.
  • the top of the column (22) is dismountable and the sealing is made by a circular ring (24).
  • a circular ring 24
  • labyrinth rings (23) to prevent the drops of the circulating must to spill out.
  • the process of thickening the must according to the invention shall be carried out as follows: a) Immediately after harvesting and pressing grapes, a selected quantity (e.g. 5%) of the same fresh must (1) has to be strained in a special container free of mechanical dirt, and after that a suction pipe (2) has to be put in it. b) A vacuum pump (11) has to be put into operation so that the created underpressure start suctioning fresh must through a suction pipe (2) into a vacuum column (5) across the filter
  • the vacuum pump (11) When the vacuum pump (11) sucks the must into a column (5), and then sucks the air to achieve the underpressure that is selected according to the desired temperature of water evaporation (this is determined by the selection of the required underpressure, e. g. 80 millibars), the vacuum pump is automatically put out of operation, and the non-return valve (10) prevents the air from returning back to the vacuum system.
  • the vacuum pump (11) is by means of pressostat, automatically put into operation again (as in a household well pump).
  • This process allows the continuous thickening of the must that may last as long as there is must, electricity and water.
  • the thickened must prepared according to this process may, after the operation is resumed, achieve the primary quality as soon as the same adjusted temperature and pressure parameters are achieved in both circular processes.
  • This apparatus doesn't produce any bad effects to the environment, because it doesn't pollute the environment and while used doesn't produce any hazardous waste. Therefore, it may be considered as ecologically acceptable. Having a total mass of approx. 100 kg the apparatus is designed as portable. Such a portable apparatus shall satisfy the treatment of must in a quantity of 1 wagon/day (approx. 6000 1/day). For the treatment of larger quantities of must it shall be necessary and possible to construct an apparatus of a stationary type, of bigger dimensions and therefore, if necessary, design assemblies and fittings of bigger capacity. A significant characteristic of the manner of application of this apparatus according to the invention is its continuous operation.
  • this apparatus may also be applied to other similar products: the invention allows the cool thickening of various fruit juices, and other beverages such as milk and the like, without using preservative(s).
  • the apparatus is designed in such a way that a serial production of its portable version is possible at a relatively low price, making it available to the majority of our vine growers.

Abstract

L'invention concerne un appareil portable permettant d'épaissir le moût de manière continue à de basses températures afin d'en augmenter le contenu en sucre sans ajouter de saccharose. L'invention concerne également deux procédés de chauffage circulaire parallèles consistant 1) à chauffer le moût afin de l'épaissir, à effectuer un vide et à liquéfier un flux de vapeur par refroidissement; et 2) à comprimer et dilater un milieu de refroidissement qui fonctionne comme un échangeur de chaleur. Ledit appareil comprend un récipient (1) de moût, un tuyau d'aspiration (2), un filtre (3), un régulateur de niveau (4), une colonne à vide (5), une ligne de flux (6), un dispositif de pré-refroidissement (7) d'eau, un condensateur de vapeur (8), un récipient de condensat (9), un clapet de non retour (10), une pompe à vide (11), un tuyau de drainage (12) de condensat, une pompe de circulation (13), un clapet de trop-plein (14), un récipient (17) de moût épaissi, un dispositif de chauffage (15) de moût, une buse (16), un compresseur (18) de milieu de refroidissement, un dispositif de dilatation (19), des raccords et un pipeline d'interconnexion. L'utilisation de cet appareil et de ce procédé permet d'épaissir de manière continue différents jus de fruit et boissons lactées. Pour obtenir une production plus importante, l'appareil portable peut être remplacé par un appareil fixe.
