Device used to quickly bring to a temperature below 0 ºC foods that should be preserved for a long

Short and simple collection of the most famous inventions and discoveries that revolutionized the world, the technology at the service of man, since the invention of the wheel to the laser beam and space travel, news of scientific breakthroughs, discoveries of recent times. The development of man, society and human knowledge.
Appliance, apparatus, machine or household utensil that works by electricity; by extension, the term is also used to designate those devices that have a similar use and utilize a fuel gas.
The increasing proliferation of various types of appliances, from the freezer to the electric knife, increasingly difficult to make a rigorous classification. White appliances and gray or black appliances: From the commercial point of view however only two groups, identifiable by their traditional color are distinguished. Since the second group is constituted in practice by devices for recording and reproduction of sound (tape or tape recorders, radios and record players, etc.) or image (such as cameras and camcorders, projectors and televisions), this article will be discussed only the most common, which are also generally the most important ones in the first group. The endless series convotherm combi oven of so-called 'small appliances' as dryers, electric shavers, mixers and toasters, simple and intuitive operation was also omitted.
Called stove in some countries, is a multipurpose device used for cooking food. Is comprised generally of a series of electric hotplates (the 'plates') or of gas burners (the 'fire'), or by a combination of both in variable number, convotherm combi oven and a furnace which can also be electric or gas, but are frequent furnaces equipped with both systems. Sometimes, the kitchen has a lower gap (called warmers) used to keep hot freshly cooked meals.
Device used to quickly bring to a temperature below 0 ºC foods that should be preserved for a long time, or to keep the products and frozen without interrupting the cold chain. It works basically like a cold compression, which is usually linked to form one unit, although sometimes has its own compressor.
Apparatus for heating the interior of the house for energy using electricity or gas. The main element of electric stoves is one or more resistors, of variable shape and power, which in most cases directly heat the surrounding air, and can be visible or behind a protective screen; in other types of viral resistance heaters raise the temperature of a fluid (usually convotherm combi oven oil) in a closed circuit. In the latter case, the operation is similar to the radiators of central heating installations, and in fact these models are similar to portable radiators appearance, and are commonly called 'oil coolers'. In general, gas stoves used butane gas contained in steel cylinders, and are of the type called convotherm combi oven 'catalytic', consist of a large container of parallel pipes mounted on a cart with wheels, convotherm combi oven in which the cylinder is housed gas. One of the vertical sides, behind a protective screen, is a plate provided with small holes through which the gas leaves, which, on burning, heats the room. These stoves, although very effective in performance, they require certain precautions of use and rigorous maintenance.
Device used for low temperature convotherm combi oven storage of perishable foods. According to the principle in which the production of cold is based, convotherm combi oven two types, the compression and absorption differ. To reduce the temperature, the first use compression and subsequent expansion of a gas, while absorption and subsequent evaporation advantage condensation of a mixture of ammonia water and heated by an electric resistance (see cooling). The first type is much more widespread than the second because it, while having the advantage of being absolutely convotherm combi oven silent, consume more.
Three types of these devices is basically distinguished. Gas furnaces are always incorporated into the kitchen (stove), while electric can be a standalone device, since, by requiring only one cable connection to the mains, convotherm combi oven are easily moved. Different by its operating principle are my ovens
