A stovetop pressure cooker. A pressure cooker is a sealed vessel for cooking food with the use of high pressure steam and water or a water-based liquid, a process called pressure cooking. The high pressure limits boiling and creates higher temperatures not possible at lower pressures, allowing food to be cooked faster than at normal pressure.
The steam digester or bone digester (also known as Papin’s digester) is a high-pressure cooker invented by French physicist Denis Papin in 1679. It is a device for extracting fats from bones in a high-pressure steam environment, which also renders them brittle enough to be easily ground into bone meal .
Steaming is a method of cooking using steam. This is often done with a food steamer, a kitchen appliance made specifically to cook food with steam, but food can also be steamed in a wok. In the American Southwest, steam pits used for cooking have been found dating back about 5,000 years.
A steam cooker catchment which collects water with condensed nutrients Broccoli in a metal steamer pot. Most steam cookers also feature a juice catchment which allows all nutrients (otherwise lost as steam) to be consumed. When other cooking techniques are used (e.g., boiling), these nutrients are generally lost, as most are discarded after ...
A cross-section of a proportional-safety valve. The earliest and simplest safety valve was used on a 1679 steam digester and utilized a weight to retain the steam pressure (this design is still commonly used on pressure cookers); however, these were easily tampered with or accidentally released.
Denis Papin FRS (French pronunciation: [dəni papɛ̃]; 22 August 1647 – 26 August 1713) [1] was a French physicist, mathematician and inventor, best known for his pioneering invention of the steam digester, the forerunner of the pressure cooker, the steam engine, [2] [3] the centrifugal pump, submersible and possibly the paddlesteamer (1707).
A rice cooker or rice steamer is an automated kitchen appliance designed to boil or steam rice. It consists of a heat source, a cooking bowl, and a thermostat. The thermostat measures the temperature of the cooking bowl and controls the heat. Complex, high-tech rice cookers may have more sensors and other components, and may be multipurpose.
A commercial combi steamer with 6 levels A household combi steamer with 4 levels, cabinet-mounted. Combi steamers (also called combi-steamers, hot-air steamers, combination steam-convection ovens, or simply combi ovens) are combination ovens that expand upon standard convection ovens in that they can also generate conventional moist steam or superheated steam and are capable of shifting ...
