Preferably, in the above stage, the rice is soaked in water for 10min-40min to make the rice fully absorb water, and make the water content of the rice reach 30% -55%, so as to obtain good taste.

In the draining stage, the vacuum pump 4 stops working, and as the heating device 2 heats water to generate steam, the steam flows from the water storage cavity 121 to the cooking cavity 111, so that the air pressure difference between the two gradually decreases until the air pressure between the two is basically balanced, and at the moment, the water in the cooking cavity 111 flows back to the water storage cavity 121 under the action of self gravity to be separated from the rice.

In the pre-gelatinization stage, after the water in the water storage cavity 121 is heated to a second preset temperature (such as 90 ℃ -98 ℃) by the heating device 2, the vacuum pump 4 is started again, so that the cooking cavity 111 is in the negative pressure state, at the moment, part of the water in the water storage cavity 121 flows into the cooking cavity 111 again under the action of the air pressure difference, the rice in the cooking cavity 111 is soaked, and the surface of the rice is gelatinized due to higher water temperature to form a starch film, so that the rate of continuous water absorption of the rice grains is reduced, and the rice obtains certain hardness, namely has certain soft and hard mouthfeel.

Preferably, in the process, the soaking time of the rice in the water is 1min-15min, and the user can select the soaking time of the rice at the stage according to personal preference so as to obtain the rice with different soft and hard mouthfeel (the longer the soaking time, the more wet and soft the mouthfeel of the rice), so that the requirements of different users are met, and the user experience is improved.

In the steam cooking stage, the vacuum pump 4 stops working, steam flows from the water storage cavity 121 to the cooking cavity 111, so that the air pressure difference between the two is gradually reduced until the air pressure between the two is basically balanced, and at the moment, water in the cooking cavity 111 flows back to the water storage cavity 121 under the action of self gravity to be separated from rice. The heating device 2 boils the water in the water storage cavity 121, and the rice in the cooking cavity 111 is steamed by using the steam until the rice is cooked.
