Rice Cooker Steam Vent Cap Design Explained


Compared to conventional rice cookers, advanced rice cookers that utilize a microcomputer like Zojirushi are sleeker, with tight-fitting components and lids. These types of rice cookers with steam venting systems consist of three components – a vent, vent cap, and vent cap receptacle.

The vent is a tube-like opening that goes through the cover and inner lid, into the body of the rice cooker where the inner pan rests. The vent is covered by the steam vent cap, which rests in the steam vent cap receptacle, keeping it securely on the cover of the rice cooker. The entire system is built to seamlessly blend into the top of the rice cookers.

Once the rice begins to cook, the rice cooker releases excess steam through the vent, and the steam vent cap catches any foamy substances that come out with the steam. The rice cooks better this way because the steam vent cap allows the rice cooker to cook your rice at a higher heat, without worrying about overflow because the steam vent cap can capture excess moisture and bubbles that may foam up.

Knowing every component of your rice cooker is important so that your rice always comes out at its best possible quality. As long as the vent cap is washed under running water, the steam vent cap receptacle area is wiped with a soft cloth to remove any moisture, and the inner lid is regularly cleaned, the steam venting system in your advanced rice cooker should work wonderfully.
