Abstract

Controlling a temperature of a wine fermentation vessel comprises a device which supplies heating and cooling fluids, where the fluids pass through tubes in which a turbulence is induced under a vortex effect.

Description

SYSTEME DE MAITRISE DE TEMPERATURE
I1 est connu qu un apport d'énergies, chaude et froide, est nécessaire pendant la vinification.TEMPERATURE CONTROL SYSTEM
It is known that a supply of energy, hot and cold, is necessary during winemaking.

Cet apport est réalisé habituellement par unucircula- tion de flux liquides, l'un refroidi par un groupe frigorifique, l'autre chauffé par une chaudière
I1 est également connu qu'au sein d'une tubulure convena blement construite, et alimentée par de l'air comprimé, il se produit un vortex, tourbillon creux, lors de l'écou lement de l'air : l'air comprimé, introduit en effet sous pression par une ouverture tangentielle, créé un vortex, tourbillonnant à grande vitesse le long du tube, jus qu a une extrémité obturée partiellement. Le courant d'air chaud qui s'échappe par cette extrémité monte en température par rapport à celle de l'air apporté.This supply is usually made by a circulation of liquid flows, one cooled by a refrigeration unit, the other heated by a boiler
It is also known that within a suitably constructed tubing, and supplied with compressed air, a vortex, a hollow vortex, occurs when the air flows: the compressed air, indeed introduced under pressure through a tangential opening, created a vortex, swirling at high speed along the tube, until a partially closed end. The current of hot air that escapes through this end rises in temperature relative to that of the air supplied.

L'air qui ne peut s'échapper à cause de l'obturation, remonte dans l'intérieur creux du vortex et se détend au niveau de la deuxième extrémité (libre) du tube; il constitue alors un flux d'air froid
Les puissances mises en jeu par un tel dispositif sont importantes, par rapport à la consommation d'air comprimé, introduit sous des pressions relativement faibles ( 5 à 10 bars par exemple ).The air which cannot escape because of the obturation, rises in the hollow interior of the vortex and expands at the level of the second (free) end of the tube; it then constitutes a flow of cold air
The powers brought into play by such a device are significant, compared to the consumption of compressed air, introduced under relatively low pressures (5 to 10 bars for example).

L'appareillage conçu suivant l'invention, pour maîtriser la montée en température des cuves de vinification ou démarrer les fermentations dès le chargement des cuves en période froide, comprend
-un générateur de chaleur et réfrigération à vortex,
-un système de régulation,
-un échangeur de chaleur, immergé dans les cuves, recevant les flux d'air chaud et froid.The apparatus designed according to the invention, to control the rise in temperature of the wine-making tanks or to start fermentations as soon as the tanks are loaded in cold period, comprises
-a vortex heat and refrigeration generator,
-a regulation system,
-a heat exchanger, immersed in the tanks, receiving the hot and cold air flows.

--- L'énergie chaude ou froide est apportée par un tube vortex, tel que décrit ci-dessus, et dont le circuit d'utilisation des apports d'air chaud et froid est orga nisé suivant la FIG. 1 : (1) est le tube vortex; (2) l'arrivée d'air comprimé; les tubulures de (1) créent les flux chaud et froid suivant les flèches
Chaque extrémité de (1) est munie d'un raccord en "T", (3-3); les extrémités des bras du "T" portent des électrovannes (4) et (5) - sur le départ chaud - et (6) et (7) -sur le départ froid -.--- The hot or cold energy is supplied by a vortex tube, as described above, and the circuit for using the hot and cold air supplies is organized according to FIG. 1: (1) is the vortex tube; (2) the arrival of compressed air; the pipes of (1) create the hot and cold flows according to the arrows
Each end of (1) is provided with a "T" fitting, (3-3); the ends of the arms of the "T" carry solenoid valves (4) and (5) - on the hot start - and (6) and (7) - on the cold start -.

Une tubulure (8) relie l'électrovanne (5) sur le départ chaud, à une électrovanne (6) sur le départ froid. Cette tubulure porte en (9) un raccord en "T" sur lequel se branche une gaine souple (10) apportant à l'échangeur un flux
- les électrovannes (4) et (6) sont fermées,
et les électrovannes (5) et (7) ouvertes : on a en ce cas en (9) un flux d'air chaud ; FIG. 2 B
- Si les électrovannes (5) et (7) sont fermées,
et les éléctrovannes (4) et (6) ouvertes : on a en (9) , un flux d'air froid : FIG. 2 A
Pour l'utilisation dans une cuve de vinification, l'air est conduit par la gaine (I0) jusqu'à la tubulure d'entrée (11) de l'échangeur (12) immergé dans la cuve (13); l'air s 'évacue par l'extrémité libre de l'échangeur (14), FIG.A tubing (8) connects the solenoid valve (5) on the hot flow, to a solenoid valve (6) on the cold flow. This tubing carries at (9) a "T" fitting onto which a flexible sheath (10) is connected, bringing a flow to the exchanger.
- the solenoid valves (4) and (6) are closed,
and the solenoid valves (5) and (7) open: in this case there is in (9) a flow of hot air; FIG. 2 B
- If the solenoid valves (5) and (7) are closed,
and the solenoid valves (4) and (6) open: in (9), there is a flow of cold air: FIG. 2 A
For use in a wine-making tank, air is led through the sheath (I0) to the inlet pipe (11) of the exchanger (12) immersed in the tank (13); the air is evacuated through the free end of the exchanger (14), FIG.

3. Le système est régulé au moyen d'une sonde (15) et régulateur associé (16), qui par l'intermédiaire d'un relais commande les fermetures et ouvertures alternatives des vannes
L'échangeur est avantageusement réalisé en tube d'acier inoxydable; il se présente sous une forme annulaire suivant la Fig. 4 , pour être facilement immergé dans les cuves . Cet échflngeur, ne subissant aucune contrainte de pression, et n'étant traversé que par de l'air, est réalisé avec des tubes à parois très minces, facilitant les conditions d'échange
Un appareillage suivant l'invention, décrit à titre d'exemple (FIG. 5) comporte avantageusement deux éléments à vortex alimentés par la même canalisation d'air comprimé (17) chacun d'eux étant branché sur des gaines (10) et (10), permettant la régulation simultanée de 2 cuves.3. The system is regulated by means of a probe (15) and associated regulator (16), which via a relay controls the alternative closings and openings of the valves
The exchanger is advantageously made of stainless steel tube; it is in an annular form according to FIG. 4, to be easily submerged in the tanks. This exchanger, not subject to any pressure constraint, and being traversed only by air, is produced with tubes with very thin walls, facilitating the exchange conditions
An apparatus according to the invention, described by way of example (FIG. 5) advantageously comprises two vortex elements supplied by the same compressed air line (17) each of them being connected to sheaths (10) and ( 10), allowing the simultaneous regulation of 2 tanks.

En (18) se trouve la pupitre de régulation, muni des régulateurs (16).In (18) is the control console, fitted with regulators (16).

Le coffret logeant l'ensemble de ces équipements est monté sur un bâti mobile grâce à des roulettes. The box housing all of this equipment is mounted on a mobile frame by means of casters.

Le même appareillage, pour doubler la puissance installée comporte, suivant la Fig. 6., la mise en place sur la tubulure d'alimentation de l'échangeur, d'un "T" (19) dont les 2 bras reçoivent les 2 gaines des 2 tubulures (10) des vortex. Dans ce cas, la régulation des 2 vortex est couplée sur un seul régulateur. The same apparatus, to double the installed power, comprises, according to FIG. 6., setting up on the supply pipe of the exchanger, a "T" (19) whose 2 arms receive the 2 sheaths of the 2 pipes (10) of the vortices. In this case, the regulation of the 2 vortices is coupled to a single regulator.

Le dispositif tel que décrit ci-dessus peut s'appli- quer à différents équipements industriels, notamment dans l'agro-alimentaire, et plus particulièrement lorsqu' il est nécessaire de disposer d'une façon temporaire de chaleur et de réfrigération. Le bilan économique dans ce cas est particulièrement favorable au dispositif  The device as described above can be applied to various industrial equipment, in particular in the food industry, and more particularly when it is necessary to temporarily have heat and refrigeration. The economic balance in this case is particularly favorable to the system
