Introduction, composition, and difference of multi-function cooker
Just like your toaster or food processor, a multicooker is a countertop appliance. While pressure cooking is probably what you hear the most, multi-cookers often offer slow-cooking and sautéing options. Other food-specific features may include rice, beans, and yogurt. Some models include presets for specific dishes (soup, poultry, porridge, etc.), but many cookbook authors and cookbook authors recommend sticking to regular pressure cooking (mostly high pressure, but sometimes low) or sauteing (from several heat levels) Select) settings to better control heat and time.
The multi-cooker consists of an inner pot set over a heating element within a large base (see the image below for a breakdown of the components). The pressure cooking function works by creating an airtight environment. Once the appliance "reaches pressure" (which can take anywhere from a few minutes to half an hour, depending on what or how much you're cooking or the strength of the machine), air and steam cannot escape. When this happens, more energy is required to boil the liquid, raising the boiling point from 212 degrees to 250 degrees. This, in turn, makes the food cook faster. (Remember, there are also stovetop pressure cookers, which can reach higher pressures and therefore cook food faster.)
If you're wondering what's the difference between a slow cooker and a multi-cooker, aside from the fact that traditional slow cookers don't do pressure cooking, a lot depends on the construction. In multi-cookers, there is a heating element at the bottom of the base, while some slow cookers also include a strap that wraps around the sides. This, along with the fact that a multicooker is taller and has a smaller surface area than a typical slow cooker, can cause food to cook unevenly when using the slow cook function in a multicooker. A pressure cooker heats up much faster than a slow cooker (or a regular skillet on the stovetop), which is why you shouldn't take a recipe designed for a regular slow cooker and use it in a multi-purpose pot, at least without tweaking it in the case of.
