What is the reason for the rice cooker sandwiching raw rice

The cooking of undercooked rice in an electric rice cooker may be caused by insufficient water, rice quality issues, uneven heating of the inner pot, incorrect selection of function keys, or unstable voltage.

1. Insufficient water volume

Imbalance in the ratio of rice to water is a common reason. There are differences in water absorption rate among different varieties of rice, with new rice absorbing less water and aged rice requiring more water. It is recommended to measure accurately with a measuring cup, with the water surface about one finger above the rice level. If using brown rice or mixed grain rice, it is necessary to soak it in advance and increase the amount of water.

2. Rice quality issues

Aged rice or improperly stored rice grains have decreased water absorption, which can easily lead to undercooked rice. Moldy rice can cause clumping and affect heating. When selecting, observe the integrity of the rice grains and keep them dry and sealed during storage. Some imported rice needs to adjust the cooking mode.

3. Uneven heating of the inner liner

Scratches or deformations at the bottom of the inner liner can hinder heat conduction and cause local temperature deficiency. Long term use leading to fouling of the heating plate can also affect heat transfer efficiency. Regularly clean the inner container and heating plate with a soft cloth to avoid scratching with a metal spatula.

4. Incorrect selection of function keys [SEP]. Insufficient fast cooking mode time may result in undercooking, especially when cooking high-altitude areas or hard rice. According to the type of rice, it is recommended to choose between refined cooking or mixed grain mode. It is suggested to extend the insulation time for Northeastern rice. Some rice cookers require manual adjustment of the pressure valve.

5. Unstable voltage

Voltage fluctuations in old circuits or during peak electricity consumption periods can cause rice cookers to fail to reach their rated power. Manifested as repeated tripping or premature entry into insulation state. You can use a voltage regulator or avoid cooking during peak hours.

When encountering undercooked rice, you can add a small amount of boiling water to make up for it, but repeated heating will affect the taste. Daily attention should be paid to adjusting the water volume according to the rice variety, regularly maintaining the components of the rice cooker, and checking the stability of the power supply before cooking. If the phenomenon of pinching occurs frequently, it is recommended to check the temperature control system of the rice cooker or replace the inner pot. Choosing an electric rice cooker with pressure function can better adapt to different rice varieties and avoid frequent opening and checking during cooking.
