Description

PROCEDE ET DISPOSITIF DE CONTROLE D'UN TRAITEMENT DU VIN. METHOD AND DEVICE FOR CONTROLLING A TREATMENT OF WINE.

La présente invention a pour objet un procédé de contrôle d'un traitement du vin par addition de produits oenologiques ou par un traitement physique ou physicochimique et en particulier, mais non exclusivement, du passage au froid ainsi qu'un dispositif pour la mise en oeuvre du procédé.The present invention relates to a process for controlling a wine treatment by adding oenological products or by a physical or physicochemical treatment and in particular, but not exclusively, of the passage to cold as well as a device for the implementation. of the process.

On sait que le passage au froid du vin a pour but de faire précipiter artificiellement le bitartrate de potassium.We know that the purpose of cold wine is to artificially precipitate potassium bitartrate.

L'intérêt de cette méthode résulte de ce que par un filtrage approprié il est possible de séparer le bitartrate du vin ce qui empeche toute précipitation ultérieure, notamment après la mise en bouteille. En effet, ce dépôt risquerait d'exercer une action répulsive sur le consommateur.The advantage of this method results from the fact that by appropriate filtering it is possible to separate the bitartrate from the wine, which prevents any further precipitation, especially after bottling. Indeed, this deposit would risk repelling the consumer.

Bien entendu, il convient de contrôler l'efficacité de l'opération de passage au froid et la présente invention a pour but de proposer un procédé de contrôle de ce traitement ou d'un traitement analogue.Of course, it is necessary to control the effectiveness of the operation of switching to cold and the present invention aims to provide a method of controlling this treatment or a similar treatment.

Il existe plusieurs types d'appareils de contrôle dont certains peuvent fonctionner en continu. Ils reposent sur les principes suivants - a) TEST DE REFRIGERATION.There are several types of recording equipment, some of which can operate continuously. They are based on the following principles - a) REFRIGERATION TEST.

Une quantité déterminée de vin est filtrée, additionnée d'environ 1,5% d'alcool pur dans le cas de vin de Champagne pour simuler la remontée du taux d'alcool lors de la prise de mousse et placée à -40C pendant quatre jours. A la fin de cette période, la présence ou l'absence de cristaux de bitartrate est constatée visuellement.A determined quantity of wine is filtered, added with approximately 1.5% of pure alcohol in the case of Champagne wine to simulate the rise in the alcohol level when the foam is taken and placed at -40C for four days . At the end of this period, the presence or absence of bitartrate crystals is visually observed.

- b) DETERMINATION DE LA CONCENTRATION IONIQUE (PS). - b) DETERMINATION OF THE IONIC CONCENTRATION (PS).

Pour apprécier cette concentration, on dose le potassium et l'acide tartrique puis on mesure le pH du vin après passage au froid et l'on effectue le calcul. To assess this concentration, potassium and tartaric acid are measured, then the pH of the wine is measured after cold storage and the calculation is carried out.

- c) TEST DU MINICONTACT.- c) MINICONTACT TEST.

Un vin passé au froid est mis en contact avec du bitartrate exogène pendant une durée de deux heures.La différence d'acidité avant et après le test est prise comme évaluation de la stabilité.A cold wine is brought into contact with exogenous bitartrate for a period of two hours. The difference in acidity before and after the test is taken as an assessment of stability.

- d) TEMPERATURE DE SATURATION (TS). La détermination de la température de saturation est décrite par WURDIG. Cette méthode consiste à prendre un vin passé au froid et à faire varier sa conductivité avec et sans addition de bitartrate de potassium exogène. La température à laquelle la conductivité est la même avec ou sans ajout est la température de saturation TS.- d) SATURATION TEMPERATURE (TS). The determination of the saturation temperature is described by WURDIG. This method consists of taking a wine that has been cold and varying its conductivity with and without the addition of exogenous potassium bitartrate. The temperature at which the conductivity is the same with or without addition is the saturation temperature TS.

Ces différentes méthodes sont longues et nécessitent un appareillage important. La présente invention a pour objet de remédier à ces inconvénients et de permettre rapidement, à l'aide d'un appareillage simple, la détermination de la température de saturation TS, et la concentration ionique PS sur un vin passé au froid.These different methods are long and require significant equipment. The object of the present invention is to remedy these drawbacks and to rapidly allow, using a simple apparatus, the determination of the saturation temperature TS, and the ionic concentration PS on a wine which has passed the cold.

Selon la présente invention, le procédé de contrôle de l'efficacité d'un passage au froid d'un vin est caractérisé en ce qu'il consiste à : - Prendre le vin avant passage au froid et le porter à une température de 200 C; - mesurer sa conductivité; - procéder au passage au froid; - mesurer la nouvelle conductivité du vin traité à la température de 200 C. According to the present invention, the process for controlling the effectiveness of a cold passage of a wine is characterized in that it consists in: - Taking the wine before cold passage and bringing it to a temperature of 200 C ; - measure its conductivity; - switch to cold; - measure the new conductivity of the treated wine at a temperature of 200 C.

- calculer la différence entre les deux conductivités et en déduire TS et PS.- calculate the difference between the two conductivities and deduce TS and PS.

La différence ocL(2O) des conductivités -à 2O0C est proportionnelle à TS et à PS. I1 est donc ainsi possible de déterminer la concentration ionique et la température de saturation. The difference ocL (2O) of the conductivities - at 2O0C is proportional to TS and to PS. It is therefore thus possible to determine the ion concentration and the saturation temperature.

D'une série d'analyses portant sur quinze échantillons différents il ressort que la température de saturation
TS = 11,78-0,0152 L(20) et que le produit de concentration ionique
PS = 11,55- 0,148 L(20)
D'autres caractéristiques et avantages de la présente invention apparaitront au cours de la description qui va suivre d'un mode particulier de réalisation, donné uniquement à titre d'exemple non limitatif, en regard de la Fig UNIQUE qui représente un dispositif de mise en oeuvre de l'invention.From a series of analyzes on fifteen different samples it appears that the saturation temperature
TS = 11.78-0.0152 L (20) and that the product of ionic concentration
PS = 11.55 - 0.148 L (20)

Entre les vannes 8 et 9, sur la canalisation 10, est montée une pompe 7 de circulation. La canalisation 10 est reliée en aval de la pompe 7, par un conduit 13 à l'entrée d'une cellule à circulation 5 dont la sortie est connectée en aval de la pompe 7 par un conduit 14. A l'intérieur de la cellule 5, se trouve une cellule de mesure conductimétrique 6 alimentée par le conductimètre 2.La cellule 5 est imergée dans une enceinte thermostatée 4 à 2O0C telle qu'un bain-marie, par exemple. La vanne 8 est une vanne à deux entrées.Par une entrée 15, entre le vin avant traitement par le froid et par l'entrée 16 le vin après traitement. La vanne A peut également être une vanne simple reliée à un raccord en "Y" sur chacune des branches duquel sont disposées des vannes électromagnétiques. Les étages 2,3,8 et 9 sont commandés par le microprocesseur 1. In FIG., The device essentially comprises a microprocessor 1 connected, on the one hand to a conductimeter 2 and, on the other hand to a printer 3 and, by connections 11 and 12 to two input solenoid valves 8 and 9 respectively and out of the wine. Between the valves 8 and 9, on the pipe 10, is mounted a circulation pump 7. The pipe 10 is connected downstream of the pump 7, by a conduit 13 to the inlet of a circulation cell 5, the outlet of which is connected downstream of the pump 7 by a conduit 14. Inside the cell 5, there is a conductimetric measurement cell 6 supplied by the conductivity meter 2. The cell 5 is immersed in a thermostatically controlled enclosure 4 at 20 ° C. such as a water bath, for example. The valve 8 is a valve with two inlets. Through an inlet 15, between the wine before cold treatment and through inlet 16 the wine after treatment. The valve A can also be a simple valve connected to a "Y" connector on each of the branches of which the electromagnetic valves are arranged. The stages 2,3,8 and 9 are controlled by the microprocessor 1.

Le cycle opératoire est le suivant - Dansun premier temps la vanne 8 est ouverte et la vanne 9 fermée. Le circuit se remplit de vin avant traitement par le froid.The operating cycle is as follows - Firstly the valve 8 is open and the valve 9 closed. The circuit is filled with wine before cold treatment.

- Puis la vanne 8 est fermée. il y a alors circulation du vin par la pompe 7 dans le circuit, thermostatisation, mesure de la conductivité et mise en mémoire de la mesure.- Then valve 8 is closed. there is then circulation of the wine by pump 7 in the circuit, thermostatization, measurement of the conductivity and storage of the measurement.

- La vanne 9 s'ouvre et le circuit se vide - La vanne 8 s'ouvre et le circuit est rincé par du vin après traitement par le froid.- Valve 9 opens and the circuit empties - Valve 8 opens and the circuit is rinsed with wine after cold treatment.

- La vanne 9 est fermée le circuit se remplit de vin après froid. Ce vin est porté à 200C et sa conductivité est mesurée et mise en mémoire.- Valve 9 is closed the circuit fills with wine after cold. This wine is brought to 200C and its conductivity is measured and stored.

- Le microprocesseur 1 calcule Ex(20), résoud -les équations ci-dessus et imprime la température de saturation TS et le produit de concentration ionique PS. On sait ainsi immédiatement si le traitement par le froid a été suffisamment efficace ou non.- The microprocessor 1 calculates Ex (20), solves the above equations and prints the saturation temperature TS and the ion concentration product PS. We immediately know if the cold treatment has been effective enough or not.

La présente invention peut etre mise en oeuvre, mutatis mutandis, chaque fois que le traitement que l'on fait subir au vin se traduit par une variation de concentration d'un type d'ions déterminé, cette variation provenant soit du traitement proprement dit, soit de l'addition d'un produit quelconque.The present invention can be implemented, mutatis mutandis, each time that the treatment which the wine is subjected to results in a variation in concentration of a given type of ion, this variation originating either from the treatment itself, or the addition of any product.

Il va de soi que de nombreuses variantes peuvent être introduites, notamment par substitution de moyens techniquement équivalents sans sortir pour celà du cadre de l'invention. It goes without saying that many variants can be introduced, in particular by substitution of technically equivalent means without thereby departing from the scope of the invention.
