Basing on the feature of high pressure and high temperature, this product reduces the cooking time and save the energy. The principle is very simple, because the boiling point of water is affected by atmospheric pressure, pressure cooker closed up the water, the water vapor produced by evaporation heat can not diffuse into the air, only to remain in the pressure cooker, pressure cooker so that the internal environment of high temperature and pressure to form the raw material for soon steam cooked. After the raw material cooked, we can use pump absorbs next link.
