Convection Oven
A convection oven (also known as a fan-assisted oven or simply a fan oven) is an oven that has fans to circulate air around food to create an evenly heated environment. The increased air circulation causes a fan-assisted oven to cook food faster than a conventional non-fan oven, which relies only on natural convection to circulate the hot air. Fan-assisted convection ovens are commonly used for baking as well as non-food, industrial applications. When cooking using a fan-assisted oven, the temperature is usually lower compared to that of a non-fan oven, often by , to avoid overcooking the outside of the food. In the context of ovens, the term "convection" is widely used to mean "fan-assisted", but this is perhaps not the most precise way to differentiate fan-assisted ovens from conventional ovens, since both types of oven cook using convective heat transfer (transfer of heat due to the bulk movement of hot air). Conventional ovens circulate hot air using natural convection and ...

Consumer Reports
Consumer Reports (CR), formerly Consumers Union (CU), is an American nonprofit consumer organization dedicated to independent product testing, investigative journalism, consumer-oriented research, public education, and consumer advocacy. Founded in 1936, CR was created to serve as a source of information that consumers could use to help assess the safety and performance of products. Since that time, CR has continued its testing and analysis of products and services, and attempted to advocate for the consumer in legislative and rule-making areas. Among the reforms in which CR played a role were the advent of seat belt laws, exposure of the dangers of cigarettes, and more recently, the enhancement of consumer finance protection and the increase of consumer access to quality health care. The organization has also expanded its reach to a suite of digital platforms. Consumer Reports Advocacy frequently supports left-wing environmental causes, including heightened regulations on aut ...

Ovens
upA double oven A ceramic oven An oven is a tool which is used to expose materials to a hot environment. Ovens contain a hollow chamber and provide a means of heating the chamber in a controlled way. In use since antiquity, they have been used to accomplish a wide variety of tasks requiring controlled heating. Because they are used for a variety of purposes, there are many different types of ovens. These types differ depending on their intended purpose and based upon how they generate heat. Ovens are often used for cooking, where they can be used to heat food to a desired temperature. Ovens are also used in the manufacturing of ceramics and pottery; these ovens are sometimes referred to as kilns. Metallurgical furnaces are ovens used in the manufacturing of metals, while glass furnaces are ovens used to produce glass. There are many methods by which different types of ovens produce heat. Some ovens heat materials using the combustion of a fuel, such as wood, coal, or n ...

Hot Air Oven
Hot air ovens are electrical devices which use dry heat to sterilize. They were originally developed by Louis Pasteur. Generally, they use a thermostat to control the temperature. Their double walled insulation keeps the heat in and conserves energy, the inner layer being a poor conductor and outer layer being metallic. There is also an air filled space in between to aid insulation. An air circulating fan helps in uniform distribution of the heat. These are fitted with the adjustable wire mesh plated trays or aluminium trays and may have an on/off rocker switch, as well as indicators and controls for temperature and holding time. The capacities of these ovens vary. Power supply needs vary from country to country, depending on the voltage and frequency (hertz) used. Temperature sensitive tapes or biological indicators using bacterial spores can be used as controls, to test for the efficacy of the device during use. Advantages and disadvantages They do not require water and ...

Superheated Steam
Superheated steam is steam at a temperature higher than its vaporization point at the absolute pressure where the temperature is measured. Superheated steam can therefore cool (lose internal energy) by some amount, resulting in a lowering of its temperature without changing state (i.e., condensing) from a gas, to a mixture of saturated vapor and liquid. If unsaturated steam (a mixture which contains both water vapor and liquid water droplets) is heated at constant pressure, its temperature will also remain constant as the vapor quality (think dryness, or percent saturated vapor) increases towards 100%, and becomes dry (i.e., no saturated liquid) saturated steam. Continued heat input will then "super" heat the dry saturated steam. This will occur if saturated steam contacts a surface with a higher temperature. Superheated steam and liquid water cannot coexist under thermodynamic equilibrium, as any additional heat simply evaporates more water and the steam will become sat ...

Combi Steamer
Combi steamers (also called combi-steamers, hot-air steamers, combination steam-convection ovens, or simply combi ovens) are cooking appliances typically used in professional catering or food service operations. Combi steamers can produce both dry (convection) and moist (steam) heat, and are capable of shifting between them automatically during the cooking process.Schudel, Walter (2005). ''Betrieb''. Lehrbuch der Küche. p. 43. It can be used to simultaneously steam vegetables or potatoes quickly and gently, while also roasting or braising meat and fish, or baking bread. The appliance is fit for many culinary applications, including baking, roasting, grilling, steaming, braising, blanching and poaching. Combi steamers expand upon standard convection ovens in that they also generate steam or a combination of steam and superheated steam. They help gastronomy-industry professionals bridge the gap between economy and menu diversity while also maintaining the desired food quality.Pa ...

Air Fryer
An air fryer is a small countertop convection oven designed to simulate deep frying without submerging the food in oil. A fan circulates hot air at high speed, producing a crisp layer via browning reactions such as the Maillard reaction. Some product reviewers find that regular convection ovens or convection toaster ovens produce better results, or say that air frying is essentially the same as convection baking. Cooking Air fryers circulate hot air to cook food that would otherwise be submerged in oil. The air fryer's cooking chamber radiates heat from a heating element near the food, and a fan circulates hot air. The original Philips Airfryer used radiant heat from a heating element just above the food and convection heat from a strong air stream flowing upwards through the open bottom of the food chamber, delivering heat from all sides, with a small volume of hot air forced to pass from the heater surface and over the food, with no idle air circulating as in a convection o ...

Browning (chemical Process)
Browning is the process of food turning brown due to the chemical reactions that take place within. The process of browning is one of the chemical reactions that take place in food chemistry and represents an interesting research topic regarding health, nutrition, and food technology. Though there are many different ways food chemically changes over time, browning in particular falls into two main categories: enzymatic versus non-enzymatic browning processes. Browning has many important implications on the food industry relating to nutrition, technology, and economic cost. Researchers are especially interested in studying the control (inhibition) of browning and the different methods that can be employed to maximize this inhibition and ultimately prolong the shelf life of food. Enzymatic browning Enzymatic browning is one of the most important reactions that takes place in most fruits and vegetables as well as in seafood. These processes affect the taste, color, and value ...

Microwave Oven
A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer of a homogeneous, high-water-content food item. The development of the cavity magnetron in the UK made possible the production of electromagnetic waves of a small enough wavelength ( microwaves). American engineer Percy Spencer is generally credited with inventing the modern microwave oven after World War II from radar technology developed during the war. Named the "Radarange", it was first sold in 1946. Raytheon later licensed its patents for a home-use microwave oven that was introduced by Tappan in 1955, but it was still too large and expensive for general home use. Shar ...

Toaster Oven
A toaster is a small electric appliance that uses radiant heat to brown sliced bread into toast. Types Pop-up toaster In pop-up or automatic toasters, a single vertical piece of bread is dropped into a slot on the top of the toaster. A lever on the side of the toaster is pressed down, lowering the bread into the toaster and activating the heating elements. The length of the toasting cycle (and therefore the degree of toasting) is adjustable via a lever, knob, or series of pushbuttons, and when an internal device determines that the toasting cycle is complete, the toaster turns off and the toast pops up out of the slots. The completion of toasting may be determined by a timer or by a thermal sensor, such as a bimetallic strip, located close to the toast. Toasters may also be used to toast other foods such as teacakes, toaster pastry, potato waffles and crumpets, though the resultant accumulation of fat and sugar inside the toaster can contribute to its eventual failu ...
