Description

Wynalazek niniejszy dotyczy parowych kotlów do gotowania strawy o podwójnych plaszczach z blachy zelaznej, a jego celem jest zabezpieczenie ugotowanej strawy na przeciag kilkunastu godzin od straty cie¬ pla, czyli ostygania. Dotychczasowe kotly parowe do gotowania nie posiadajac war¬ stwy izolacyjnej szybko wystygaly; w celu utrzymania temperatury nalezalo dopro¬ wadzac stale pare, co przy zastosowaniu nizej opisanego wynalazku jest zbedne, przez co zaoszczedza sie w duzym stopniu na paliwie. Zastosowanie nizej opisanego wynalazku umozliwia, przez postawienie wiekszej liczby kotlów, jednorazowe w cia¬ gu dnia gotowanie, a wiec i jednorazowe palenie pod kotlem parowym, a nastepnie przetrzymywanie przez kilkanascie godzin ugotowanej strawy w kotlach, bez ich o- grzewania, co daje oszczednosc na obslu¬ dze i na opale. Zastosowanie tego wyna¬ lazku do kotlów parowych do gotowania w wojsku, jak to wykazala praktyka, daje okolo 50% oszczednosci na opale w stosun¬ ku do zwyklych kotlów paleniskowych wy¬ sokopreznych. Wynalazek polega na nalo¬ zeniu sposobem galwanicznym na we¬ wnetrzna powierzchnie zelaznego plaszcza zewnetrznego (fig. 1 i fig. 2) warstwy mie¬ dzi; oznaczonej na rysunku cyfra 2, a na¬ stepnie warstwy sirebra 3, która oblewa sie rtecia 4. Po zwiazaniu sie rteci z warstwa¬ mi srebra i miedzi, co trwa okoloi 12 godzin, cala te powierzchnie oblewa sie masa od-porna na pare, w celu zabezpieczenia rteci 4 od ulatniania sie. Masa ta sklada (sie z mimji *, olowianej,, grafitu i lakieru ogniotrwalego.Izolacja wykonana w ten sposób uniemoz¬ liwia stygniecie zawajrtosci kotla, para wy¬ twarzana w kotle parowym, która dostaje sie pomiedzy plaszcze kotla do gotowania, nie ochladza sie szybko, poniewaz rtec u- trzymuje dlugo uzyskana temperature i jednoczesnie zapobiega ostyganiu kotla z zewnatrz. Powyzsza izolacja powoduje u- trzymanie temperatury ugotowanej strawy w przeciagu okolo 14 godzin. PLThe present invention relates to steam kettles for cooking food with double iron sheaths, and its purpose is to protect the cooked food for several hours from heat loss, ie cooling. The previous cooking steam boilers without an insulating layer quickly cooled down; in order to maintain the temperature, it is necessary to constantly steam, which is unnecessary for the application of the invention described below, thus saving a great deal on fuel. The application of the invention described below makes it possible, by setting up a larger number of kettles, to cook once a day, and thus to burn once under a steam boiler, and then to keep the cooked food in the kettles for several hours without heating them, which saves money. service and fuel. The application of this invention to military steam boilers, as has been shown in practice, gives about 50% fuel savings compared to conventional high pressure furnace boilers. The invention consists in electroplating the inner surface of an iron outer mantle (Fig. 1 and Fig. 2) with a copper layer; 2 marked in the figure, followed by a layer of sireb 3, which is poured with mercury 4. After mercury is bonded to the silver and copper layers, which takes about 12 hours, all these surfaces are poured with vapor-resistant mass, in order to prevent mercury 4 from escaping. This mass consists of (mimji *, lead, graphite and refractory varnish. Insulation made in this way prevents the contents of the boiler from cooling down, the steam generated in the steam boiler, which gets between the coats of the cooking boiler, does not cool down quickly. , because mercury maintains the obtained temperature for a long time and at the same time prevents the boiler from cooling down from the outside. The above insulation keeps the temperature of the cooked food for about 14 hours. EN

Claims

1. Patent claim. A method of electroplating the inner iron surface of the outer mantle of a steam kettle for cooking food, changing the surface, where the inner surface of the outer mantle is galvanized with a copper layer 2, and then a silver layer 3, coated on it mercury 4, which, after bonding with the layers of silver and copper, which takes about 12 hours, is poured with a vapor-resistant mass, consisting of lead minja, graphite and refractory varnish, which creates an insulation on the iron surface, protecting against thistles. it eats the cooked food contained in the boiler for about 14 hours without further steam.
