Abstract
Description
La présente invention se rapporte à un appareil destiné à la fabrication de glace en pains tronconiques. The present invention relates to an apparatus intended for the manufacture of ice in frustoconical rolls.
Cet appareil est une machine frigorifique -à compression,. This device is a refrigeration machine - with compression.
comprenant notamment un évaporateur tubulaire et au moins un mouleau, que l'on remplit d'eau à transformer en glace.comprising in particular a tubular evaporator and at least one mold, which is filled with water to be transformed into ice.
Suivant l'invention, cet appareil est caractérisé -en ce que ledit mouleau est tronconique et en ce qu'il forme le support et est solidaire de l'évaporateur tubulaire de la machine frigorifique. According to the invention, this device is characterized -in that said mold is frustoconical and in that it forms the support and is integral with the tubular evaporator of the refrigerating machine.
Un contact étroit entre l'évaporateur tubulaire et le mouleau tronconique est avantageusement assuré par un déport. de métal, à chaud ou à froid, sur l'ensemble mouleau-évaporateur après assemblage. Si cet ensemble est en acier, on peut..avoir recours à une galvanisation, mais tous-autres matériaux ou métaux permettant d'obtenir un assemblage solide et un bon contact thermique peuvent être utilisés pour le mouleau. Close contact between the tubular evaporator and the frustoconical mold is advantageously ensured by an offset. of metal, hot or cold, on the mold-evaporator assembly after assembly. If this assembly is made of steel, we can use galvanizing, but all other materials or metals allowing a solid assembly and good thermal contact can be used for the mold.
l'évapo.rateur et le revêtement métallique de-liaison. the evaporator and the de-bonding metallic coating.
Compte tenu de ce mode de fabrication, le mouleau- ìt partie intégrante de l'évaporateur, la surface d'échange est très grande et l'échange. thermique est o.ptimab Le mouleau, dans ce cas, fait office d'évaporateur à détente directe", raccordé au groupe frigorifique constitué par un compresseur, un condenseur et un détendeur. Un tel groupe est classique. et bien connu. et n'est donc pas revendiqué en soi.Given this manufacturing method, the mold is an integral part of the evaporator, the exchange surface is very large and the exchange. thermique est o.ptimab The mold, in this case, acts as a direct expansion evaporator ", connected to the refrigeration unit consisting of a compressor, a condenser and an expansion valve. Such a group is classic. and well known. and n ' is therefore not claimed per se.
Une autre particularité de l'invention est que la fabrique de glace décrite ci-dessus peut être complétée par un dispositif de démoulage semi-automatique pouvant être constitué. Another feature of the invention is that the ice factory described above can be completed by a semi-automatic mold release device which can be formed.
par un pressostat basse-pression, qui arrête le groupe frigo- rifique lorsque la glace, à l'intérieur du mouleau, est fabri quée,. et par une résistance de dégivrage qu'un programmateur- met en service après l'arrêt du groupe et qui permet le démoulage du pain de glace.by a low-pressure pressostat, which stops the refrigeration unit when the ice, inside the mold, is produced. and by a defrost resistor which a programmer puts into service after the group has stopped and which allows the ice bread to be removed from the mold.
En variante,.le pressostat basse pression peut agir sur une vanne d'inversion du sens de fonctionnement de la machine frigorifique, ce qui permet le dégivrage du mouleau par innec- tion de.gaz chaud dans le serpentin évaporateur. As a variant, the low pressure pressostat can act on a valve for reversing the direction of operation of the refrigerating machine, which allows the defrosting of the mold by the injection of hot gas into the evaporator coil.
De préférence, le pain de glace est fabriqué dans un sac en plastique inséré dans-le mouleau, ce qui facilite son extraction. Le sac peut être gradué et muni de poignées. Les gradua tions ont pour but de faciliter la découpe en portions, pour la
commercialisation de la glace.Preferably, the ice bread is made in a plastic bag inserted in the mold, which facilitates its extraction. The bag can be graduated and provided with handles. The aim of the graduations is to facilitate cutting into portions, for the
marketing of ice.
La fabrique, telle que décrite ci-dessus, peut être conçue pour un ou plusieurs mouleaux dont la capacité unitaire peut varier de cinq à vingt cinq kilos. The factory, as described above, can be designed for one or more molds whose unit capacity can vary from five to twenty five kilos.
Cet appareil est prévu, notamment, pour fabriquer de la glace de consommation domestique, entre autres dans les pays chauds qui ne sont pas encore dotés d'installations industrielles de production de glace. This device is intended, in particular, to make ice for domestic consumption, inter alia in hot countries which do not yet have industrial ice production facilities.
Une forme particulière d'exécution de l'appareil suivant l'invention est décrite ci-après, à titre d'exemple purement indicatif et nullement limitatif, en référence au dessin annexé qui est une vue schématique, partiellement en coupe, de l'appareil. A particular embodiment of the apparatus according to the invention is described below, by way of purely indicative and in no way limitative example, with reference to the appended drawing which is a schematic view, partially in section, of the apparatus .
Cet appareil comprend un groupe de compression connu en soi, constitué par un compresseur 1 et un condenseur 2 ventilé en 3, l'ensemble formant un groupe haute pression. This device comprises a compression group known per se, consisting of a compressor 1 and a condenser 2 ventilated at 3, the assembly forming a high pressure group.
Le gaz frigorigène liquéfié, qui circule dans le sens des flèches, est reçu dans un réservoir 4 et asséché dans un déshydrateur 5. A l'aide d'un détendeur 6, le liquide est injecté dans l'évaporateur tubulaire 7 placé autour et solidaire (ar exemple par galvanisation) d'un mouleau tronconique 14, qui fait ainsi partie intégrante de ltévaporateur et qui a été rempli d'eau. Le gaz est aspiré par le compresseur 1 et le cycle recommence. The liquefied refrigerant gas, which circulates in the direction of the arrows, is received in a tank 4 and dried in a dehydrator 5. Using a pressure reducer 6, the liquid is injected into the tubular evaporator 7 placed around and integral (for example by galvanizing) of a frustoconical mold 14, which thus forms an integral part of the evaporator and which has been filled with water. The gas is sucked in by compressor 1 and the cycle begins again.
Un pressostat basse pression 8 arrete le groupe frigori figue lorsque la pression d'évaporation est suffisamment basse et correspond à la fin de la fabrication de la glace dans le mouleau. Une résistance de chauffage 9 entourant le mouleau, et dont la mise en service est commandée de façon connue en soi par l'arrêt du groupe frigorifique, assure alors l'apport de calories nécessaire. au dégivrage superficiel du pain de glace, maintenant contenu dans le mouleau, en vue de son extraction. A low pressure pressostat 8 stops the fig frigori group when the evaporation pressure is low enough and corresponds to the end of the production of the ice in the mold. A heating resistor 9 surrounding the mold, and the commissioning of which is controlled in a manner known per se by stopping the refrigeration unit, then ensures the necessary supply of calories. on the surface defrosting of the ice bread, now contained in the mold, with a view to its extraction.
En variante, le pressostat basse pression 8 peut agir sur une vanne 10 d'inversion du sens de fonctionnement de la machine
frigorifique, dont le condenseur fait alors office d'évaporateur et vice-versa, de façon connue en soi ; du gaz chaud est alors envoyé dans l'évaporateur par le compresseur en sens inverse des flèches indiquées sur le dessin, ce qui provoque également le dégivrage superficiel du pain de glace.As a variant, the low pressure pressostat 8 can act on a valve 10 for reversing the direction of operation of the machine.
refrigerator, the condenser of which then acts as an evaporator and vice versa, in a manner known per se; hot gas is then sent to the evaporator by the compressor in the opposite direction to the arrows indicated in the drawing, which also causes the surface defrosting of the ice bread.
Un sac en plastique 11, muni à son sommet de poignées 15 est placé avantageusement dans le mouleau pour contenir l'eau destinée à être transformée en glace et faciliter l'extraction- du pain de glace. A plastic bag 11, provided at its top with handles 15 is advantageously placed in the mold to contain the water intended to be transformed into ice and to facilitate the extraction of the bread from ice.
Le ou les mouleaux sont isolés à l'aide d'un produit d'isolation thermique 12. The mold (s) are insulated using a thermal insulation product 12.
Le ou les mouleaux ainsi que le groupe de compression sont montés sur un châssis 13, l'ensemble formant un appareil monobloc
Des modifications de détail, du domaine des équivalents techniques, peuvent être apportées au dispositif décrit ci-dessus.The mold or molds as well as the compression group are mounted on a chassis 13, the assembly forming a one-piece device
Modifications of detail, from the domain of technical equivalents, can be made to the device described above.
sans que l'on s'écarte pour autant du-domaine de l'invention.without thereby departing from the scope of the invention.
En particulier, le serpentin évaporateur peut entourer un groupe de deux ou plusieurs mouleaux accolés lui -servant de support. In particular, the evaporator coil can surround a group of two or more adjoining molds serving as a support.
