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.
Instant Pot is a brand of multicookers manufactured by Instant Pot Brands. The multicookers are electronically controlled, combined pressure cookers and slow cookers.. The original cookers were marketed as 6-in-1 appliances designed to consolidate the cooking and preparing of food to one device.
Originally called "Northwestern Steel and Iron Works" the company changed its name to the "National Pressure Cooker Company" in 1929 and then National Presto Industries, Inc. 1953. [3] The company originally produced pressure canners for commercial, and later home, use. Beginning in 1939, the company introduced small home-use cooking appliances.
A pressure cooker. Pressure cooker – heats food quickly because the internal steam pressure from the boiling liquid causes saturated steam (or "wet steam") to bombard and permeate the food. Thus, higher temperature water vapour (i.e., increased energy), which transfers heat more rapidly compared to dry air, cooks food very quickly.

The surface of the cooker is heated only by the pot and so does not usually reach a high temperature. The thermal conductivity of glass ceramics is poor so the heat does not spread far. Induction cookers are easy to clean because the cooking surface is flat and smooth and does not usually get hot enough to make spilled food burn and stick.
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 .
