Abstract
Description
La détermination précise du titre alcoométrique des vins et des milieux fermentés s'obtient généralement par l'une des méthodes suivantes:
- La pycnométrie
- La réfractométrie
- La balance hydrostatique
- I'aréométrie, mesure la plus courante.The precise determination of the alcoholic strength of wines and fermented media is generally obtained by one of the following methods:
- Pycnometry
- Refractometry
- Hydrostatic balance
- areometry, the most common measurement.
Tous ces procédés impliquent, comme le stipulent les méthodes officielles, I'obtention préalable d'un milieu hydro-alcoolique de même titre que celui du liquide à analyser ; I'utilisation d'un appareil de distillation constitue donc une première démarche essentielle. All these processes imply, as stipulated by the official methods, the prior obtaining of a hydroalcoholic medium in the same way as that of the liquid to be analyzed; The use of a distillation apparatus therefore constitutes an essential first step.
La distillation directe reste le procédé le plus simple et le plus utilisé. Direct distillation remains the simplest and most used process.
Cette opération technique, très ancienne, a été mise en oeuvre avec des variantes par de nombreux promoteurs, en particulier:
Blarez,
Colombier et Clair,
Cachier,
Jaulmes
Tous ces procédés ont en commun le chauffage de ballons contenant la boisson à analyser, le plus souvent au moyen d'un bec de gaz.This very old technical operation has been implemented with variations by many promoters, in particular:
Joke,
Colombier and Clair,
Cachier,
Jaulmes
All of these processes have in common the heating of flasks containing the beverage to be analyzed, most often by means of a gas nozzle.
Ils impliquent de la part de l'opérateur,
- une surveillance continue, car si la distillation est prolongée trop longtemps, des risques de pyrogénation sont à craindre ainsi que l'assèchement du ballon et sa détérioration.They involve on the part of the operator,
- continuous monitoring, because if the distillation is prolonged too long, there is a risk of pyrogenation as well as the drying of the flask and its deterioration.
- la manipulation de verreries brûlantes pour élimination des vinasses et nouveau remplissage dans le cas de séries analytiques. - handling of burning glassware to eliminate vinasses and refilling in the case of analytical series.
- une immobilisation longue : chaque opération nécessitant entre 20 et 30 minutes. - a long immobilization: each operation requiring between 20 and 30 minutes.
Sur l'essentiel de l'appareillage, peu de progrès ont été réalisés au cours des dernières cinquante années. On the main part of the apparatus, little progress has been made during the last fifty years.
Notre invention consiste en la mise au point d'un appareillage simple n'utilisant que l'énergie électrique et permettant:
- de se conformer à l'extraction de l'alcool en 7 minutes environ avec ia distillation des 3/4 du volume mis en oeuvre.Our invention consists in the development of a simple apparatus using only electrical energy and allowing:
- to comply with the alcohol extraction in about 7 minutes with ia distillation of 3/4 of the volume used.
- la réalisation de cette opération sans l'asservissement d'un analyste. - carrying out this operation without the subjugation of an analyst.
- I'élimination de tout risque de pyrogénation pendant le chauffage. - the elimination of any risk of pyrogenation during heating.
- la réalisation des opérations de vidange par un simple jeu de robinet, en évitant donc démontages et remontages des ballons utilisés. - carrying out the emptying operations with a simple set of taps, thus avoiding disassembly and reassembly of the tanks used.
- une économie de temps considérable (le tiers de celui exigé préalablement) . - considerable time savings (one third of that previously required).
Comme c'est souvent le cas avec l'utilisation d'un appareil adapté, on obtient une extraction de l'alcool d'une rigueur parfaitement conforme aux prescriptions communautaires (J.O. du 14/5/1982) et internationales (Recueil O.l.V. de janvier 1990):
"Distiller 5 fois successives un mélange hydrocalcoolique titrant 10 %
V, le distillat doit présenter un titre alcoométrique d'au moins 9,9 % V après la cinquième distillation".As is often the case with the use of a suitable device, we obtain an alcohol extraction of a rigor perfectly in conformity with the Community prescriptions (OJ of 5/14/1982) and international (Collection OlV of January 1990):
"Distill 5 times a hydrocalcoholic mixture titrating 10%
V, the distillate must have an alcoholic strength of at least 9.9% V after the fifth distillation ".
Notre invention donne également des résultats satisfaisants dans le cas des alcools et spiritueux. Our invention also gives satisfactory results in the case of alcohols and spirits.
Les différents éléments de l'appareil sont les suivants : un ballon de 500 ml à 11(A) sorte d'ampoule à décanter, dont la partie supérieure est surmontée de 3 canalisations. The different elements of the device are as follows: a 500 ml balloon at 11 (A), a sort of separating funnel, the upper part of which is surmounted by 3 pipes.
L'une des canalisations extrêmes (N"1) sert au remplissage du vin, et l'autre (N"3) au passage de la vapeur vers un dispositif (B), destiné à éviter le primage avant la condensation dans le réfrigérant métallique (D). One of the extreme pipes (N "1) is used for filling the wine, and the other (N" 3) for the passage of steam to a device (B), intended to prevent priming before condensation in the metallic refrigerant (D).
A travers la canalisation centrale (N"2) est implantée une résistance (R) de 1000 Watts environ alimentée en 220 Volts et plongeant jusqu'à la partie la plus basse du ballon. Through the central pipe (N "2) is installed a resistance (R) of 1000 Watts approximately supplied with 220 Volts and plunging to the lowest part of the balloon.
Cette résistance est d'une conception tout à fait originale. This resistance is of an entirely original design.
Elle est implantée par la partie haute non chauffante ce qui élimine les risques de détérioration des joints et les pertes par suintements. It is installed by the upper non-heating part which eliminates the risks of deterioration of the joints and losses by seepage.
Elle n'apporte ses calories que par sa partie basse terminale qui reste immergée jusqu'à la fin de l'opération dans le reliquat non distillable (vidangé à l'égout en fin d'opération par le robinet C). It only provides its calories through its lower terminal part which remains submerged until the end of the operation in the non-distillable residue (emptied into the sewer at the end of the operation by tap C).
Elle est naturellement parfaitement programmable dans son temps de travail et se prête à une excellente régulation de l'appareil avec arrêt du courant d'alimentation et mise sous tension d'un signal électrique de fin d'opération. It is naturally perfectly programmable in its working time and lends itself to excellent regulation of the device with stopping the supply current and energizing an electrical signal at the end of the operation.
Par son dispositif général, L'appareil se prête à un montage en batterie de 2, 3 ou 4 éléments, etc... assurant ainsi des performance exceptionnelles. By its general device, the device lends itself to battery mounting of 2, 3 or 4 elements, etc ... thus ensuring exceptional performance.
La marche de l'appareil est des plus simples. The operation of the device is very simple.
Après mesure très exacte dans une fiole jaugée du volume à distiller (200 ml ou 250 ml), et son introduction dans l'appareil, on ajoute à 8 à 10 ml de solution alcalinisante. After very exact measurement in a volumetric flask of the volume to be distilled (200 ml or 250 ml), and its introduction into the apparatus, 8 to 10 ml of alkalizing solution are added.
Le seul fait de mettre l'appareil sous tension permet l'obtention automatique par distillation des 3/4 du volume introduit, puis arrêt de l'ensemble et signal. The mere fact of turning on the device allows automatic obtaining by distillation of 3/4 of the volume introduced, then stopping of the assembly and signal.
L'opérateur, au moment qui lui paraîtra opportun, n'aura plus qu'à ajuster la fiole jaugée au volume initial pour obtenir après homogénéisation un distillat hydroalcoolique exactement de même titre que celui de la boisson à analyser. The operator, at the time that seems appropriate, will only have to adjust the volumetric flask to the initial volume to obtain, after homogenization, a hydroalcoholic distillate in exactly the same way as that of the beverage to be analyzed.
Le reste de l'analyse suivra alors selon le mode opératoire choisi. The rest of the analysis will then follow depending on the procedure chosen.
Remarquons qu'après vidange, L'appareil se trouve prêt dans l'immédiat pour une autre opération. Note that after emptying, the appliance is immediately ready for another operation.
