Cooker
Cooker may refer to several types of cooking appliances and devices used for cooking foods. Types * AGA cooker – a heat storage stove and cooker, which works on the principle that a heavy frame made from cast iron components can absorb heat from a relatively low-intensity but continuously-burning source, and the accumulated heat can then be used when needed for cooking. Originally heated by slow-burning coal, the Aga cooker was invented in 1922 by the Nobel Prize-winning Swedish physicist Gustaf Dalén (1869–1937), who was employed first as the chief engineer of the Swedish AGA company * Cook stove – heated by burning wood, charcoal, animal dung or crop residue. Cook stoves are commonly used for cooking and heating food in households that lack access to clean, modern facilities for cooking. * Electric cooker – an electric powered cooking device for heating and cooking of food * Gas stove (British English) – uses natural gas, propane, butane, liquefied p ...

AGA Cooker
The Aga Range Cooker is a Swedish range Kitchen stove, cooker. Invented and initially produced in Sweden, since 1957 most production has been located in the UK. In 2015, the British AGA Cooker manufacturing company, AGA Rangemaster Group, was acquired by the American corporation Middleby. History Originally developed to burn coal or anthracite, the Aga range cooker was invented in 1922 by the Nobel Prize-winning Swedish physicist Gustaf Dalén (1869–1937), who was employed as the chief engineer of the Swedish AGA AB, AGA company (Swedish language, Swedish ''Svenska Aktiebolaget Gasaccumulator'', English ''Swedish Gas Accumulator, Limited''). "AGA" stands for Aktiebolaget Gas Accumulator. Dalén lost his sight in an explosion while developing his earlier invention, a porous Substrate (materials science), substrate for storing gases, Agamassan. Forced to stay at home, Dalén discovered that his wife was exhausted by cooking. Although blind, he set out to develop a new stove tha ...

Extractor Hood
A kitchen hood, exhaust hood, hood fan, extractor hood, or range hood is a device containing a mechanical fan that hangs above the stove or cooktop in the kitchen. It removes airborne grease, combustion products, fumes, smoke, heat, and steam from the air by evacuation of the air and filtration. In commercial kitchens exhaust hoods are often used in combination with fire suppression devices so that fumes from a grease fire are properly vented and the fire is put out quickly. Commercial vent hoods may also be combined with a fresh air fan that draws in exterior air, circulating it with the cooking fumes, which is then drawn out by the hood. In most exhaust hoods, a filtration system removes grease (the grease trap) and other particles. Although many vent hoods exhaust air to the outside, some recirculate the air to the kitchen. In a recirculating system, filters may be used to remove odors in addition to the grease. The device is known as an extractor hood in the United Kingdom, ...

Cooking
Cooking, also known as cookery or professionally as the culinary arts, is the art, science and craft of using heat to make food more palatable, digestible, nutritious, or Food safety, safe. Cooking techniques and ingredients vary widely, from grilling food over an open fire to using electric stoves, to baking in various types of ovens, reflecting local conditions. Types of cooking also depend on the skill levels and training of the Cook (profession), cooks. Cooking is done both by people in their own dwellings and by professional cooks and chefs in restaurants and other food establishments. Preparing food with heat or fire is an activity unique to humans. Archeological evidence of cooking fires from at least 300,000 years ago exists, but some estimate that humans started cooking up to 2 million years ago. The expansion of agriculture, commerce, trade, and transportation between civilizations in different regions offered cooks many new ingredients. New inventions and technolog ...

Stove
A stove or range is a device that generates heat inside or on top of the device, for - local heating or cooking. Stoves can be powered with many fuels, such as natural gas, electricity, gasoline, wood, and coal. Due to concerns about air pollution, efforts have been made to improve stove design. Pellet stoves are a type of clean-burning stove. Air-tight stoves are another type that burn the wood more completely and therefore, reduce the amount of the combustion by-products. Another method of reducing air pollution is through the addition of a device to clean the exhaust gas, for example, a filter or afterburner. Research and development on safer and less emission releasing stoves is continuously evolving. Etymology Old English had a word ''stofa'', meaning a hot-air bath or sweating room. However, this usage did not survive, and the word was taken newly from Middle Low German or Middle Dutch in the 15th or 16th century, later meaning any room heated with a furnace. By the ...

Kitchen Stove
A kitchen stove, often called simply a stove or a cooker, is a kitchen appliance designed for the purpose of cooking food. Kitchen stoves rely on the application of Heat transfer#Conduction, direct heat for the cooking process and may also contain an oven, used for baking. "Cookstoves" (also called "cooking stoves" or "wood stoves") are heated by burning wood or charcoal; "gas stoves" are heated by gas; and "electric stoves" by electricity. A stove with a built-in cooktop is also called a range. In the industrialized world, as stoves replaced open fires and braziers as a source of more efficient and reliable heating, models were developed that could also be used for cooking, and these came to be known as ''kitchen stoves''.Montagne, Prosper ''New Larousse Gastronomique'' Hamlin Publishing Group 1977 268,901 Quoting Eugène Viollet-le-Duc on cooking in the Middle Ages: "The division of stoves into several compartments as in our day was seldom seen.

Induction Cooking
Induction cooking is a cooking process using direct electrical induction heating of Cookware and bakeware, cookware, rather than relying on flames or Heating element, heating elements. Induction cooking allows high power and very rapid increases in temperature to be achieved: changes in heat settings are instantaneous. Pots or pans with suitable bases are placed on an induction electric stove (also ''induction hob'' or ''induction cooktop'') which generally has a heat-proof glass-ceramic surface above a coil of copper wire with an alternating current, alternating electric current passing through it. The resulting oscillating magnetic field induces an electrical current in the cookware, which is Resistive heating, converted into heat by resistance. To work with induction, cookware must contain a Ferromagnetism, ferromagnetic metal such as cast iron or some stainless steels. Induction tops typically will not heat copper or aluminum cookware because the magnetic field cannot produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kitchen Appliance
A home appliance, also referred to as a domestic appliance, an electric appliance or a household appliance, is a machine which assists in household functions such as cooking, cleaning and food preservation. The domestic application attached to home appliance is tied to the definition of appliance as "an instrument or device designed for a particular use or function". ''Collins English Dictionary'' defines "home appliance" as: "devices or machines, usually electrical, that are in your home and which you use to do jobs such as cleaning or cooking". The broad usage allows for nearly any device intended for domestic use to be a home appliance, including consumer electronics as well as stoves, refrigerators, toasters and air conditioners. The development of self-contained electric and gas-powered appliances, an American innovation, emerged in the early 20th century. This evolution is linked to the decline of full-time domestic servants and desire to reduce household chores, allowing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferromagnetic
Ferromagnetism is a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. Ferromagnetic materials are noticeably attracted to a magnet, which is a consequence of their substantial magnetic permeability. Magnetic permeability describes the induced magnetization of a material due to the presence of an external magnetic field. For example, this temporary magnetization inside a steel plate accounts for the plate's attraction to a magnet. Whether or not that steel plate then acquires permanent magnetization depends on both the strength of the applied field and on the coercivity of that particular piece of steel (which varies with the steel's chemical composition and any heat treatment it may have undergone). In physics, multiple types of material magnetism have been distinguished. Ferromagnetism (along with the similar effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat Transfer
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, Convection (heat transfer), thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species (mass transfer in the form of advection), either cold or hot, to achieve heat transfer. While these mechanisms have distinct characteristics, they often occur simultaneously in the same system. Heat conduction, also called diffusion, is the direct microscopic exchanges of kinetic energy of particles (such as molecules) or quasiparticles (such as lattice waves) through the boundary between two systems. When an object is at a different temperature from another body or its surroundings, heat flows so that the body and the surroundings reach the same temperature, ...

Induction Heating
Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold, silver, aluminum, or carbide. An important feature of the induction heating process is that the heat is generated inside the object itself, instead of by an external heat source via heat conduction. Thus objects can be heated very rapidly. In addition, there need not be any external contact, which can be important where contamination is an issue. Induction heating is used in many industrial processes, such as heat treatment in metallurgy, Czochralski process, Czochralski crystal growth and zone refining used in the semiconductor industry, and to melt refractory metals that require very high temperatures. It is also used in induction cooking, induction cooktops. An induct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooking Vessel
Cookware and bakeware is food preparation equipment, such as cooking pots, pans, baking sheets etc. used in kitchens. Cookware is used on a stove or range cooktop, while bakeware is used in an oven. Some utensils are considered both cookware and bakeware. There is a great variety of cookware and bakeware in shape, material, and inside surface. Some materials conduct heat well; some retain heat well. Some surfaces are non-stick; some require seasoning. Some pots and their lids have handles or knobs made of low thermal conductance materials such as bakelite, plastic or wood, which make them easy to pick up without oven gloves. A good cooking pot design has an "overcook edge" which is what the lid lies on. The lid has a dripping edge that prevents condensation fluid from dripping off when handling the lid (taking it off and holding it 45°) or putting it down. History The history of cooking vessels before the development of pottery is minimal due to the limited archaeolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel
A fuel is any material that can be made to react with other substances so that it releases energy as thermal energy or to be used for work (physics), work. The concept was originally applied solely to those materials capable of releasing chemical energy but has since also been applied to other sources of heat energy, such as Nuclear power, nuclear energy (via nuclear fission and nuclear fusion). The heat energy released by reactions of fuels can be converted into mechanical energy via a heat engine. Other times, the heat itself is valued for warmth, cooking, or industrial processes, as well as the illumination that accompanies combustion. Fuels are also used in the Cell (biology), cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy. Hydrocarbons and related organic molecules are by far the most common source of fuel used by humans, but other substances, including radioactive metals, are also utilized. Fu ...
