What is 1D, 2D, 3D rice cooker?

There are many different types of rice cookers on the market: electronic rice cookers, high-frequency electric rice cookers, etc. cook 1D, 2D, 3D. Let’s find out and distinguish with Tnhelearning.edu.vn in this article.

How many types of rice cookers are there?

There are 3 types of rice cookers when divided according to the criteria of heat generation system, including:

– Type 1 : The rice cooker has 1 main heating element – a large thermistor part generates heat to cook the rice, it is located at the bottom of the pot body, round like a tray, so it is often called a heating plate.

– Type 2 : The rice cooker has 1 heating plate on the bottom of the pot body + 1 – 2 auxiliary heating elements – a small thermistor part, which is wrapped around the body of the pot and located on the lid of the pot.

– Type 3 : The rice cooker does not have a heating plate , using magnetic induction to heat the inner pot directly, this type of heat generation is common in high-frequency rice cooker models.

What is the heating plate of the rice cooker?

The heating plate is the heating system of the rice cooker. Has a structure similar to an induction cooker, including a resistance wire placed in an insulated heat-resistant tube, installed on a tray on the bottom of the pot. The middle of the tray has a heat sensor, which automatically turns off when it reaches a certain temperature, that is, when the rice is cooked, the pot automatically switches to the keep-warm mode.

The quality of the heating plate has a direct effect on the durability of the rice cooker. Cheap rice cookers of unreputable brands use poor quality magnets in the heating plate, making the pot easy to short circuit, damage the spring, resulting in uncooked or burnt rice. The heating system has a significant effect on the quality of rice grains, specifically, whether the rice is delicious, flexible, cooked, and not crushed.

1D cooking technology

That is, the rice cooker has only a single heating plate on the bottom of the pot, using high power to cook rice, so the rice is cooked quickly , only from 20 minutes to half an hour. However, because it only focuses on heating at the bottom of the pot, it is difficult to adjust the quality of the rice grains, the rice is easily dry or pasty if the amount of water is too little or too much.

The 1D rice cooker is quite cheap, ranging from 200,000 VND to 1,200,000 VND. Usually available in the line of rice cookers with removable lids , lids or some mid-range electronic rice cookers.

2D cooking technology

A type of rice cooker with 1 main heating plate on the bottom of the pot + 1 auxiliary thermistor (around the body or on the lid). Cook rice evenly and deliciously with heat evenly distributed around the body and bottom of the pot.

2D cooking mode often appears in the line of rice cookers with lids or mid-range electronic rice cookers, priced from 600,000 VND to 2,000,000 VND.

3D cooking technology

This is a type of rice cooker with 1 main heating plate on the bottom of the pot + 2 auxiliary thermistor components (around the body or on the lid). The hot plate will evaporate the water deposited on the pot, helping to spread the heat evenly from all sides for the rice grains to be spongy, evenly cooked, more delicious, without worrying about being dry or mushy when cooking. However, the cooking time is quite long and the price is very high, in return, the rice is delicious.

Rice cookers using 3D cooking technology cost approximately from 1,800,000 VND to over 2,000,000 VND.

High-frequency cooking technology

It is a type of rice cooker that uses magnetic induction to heat the pot directly. With the mechanism of heat radiating on the lid, the steam on the lid evaporates, then direct transmission to help the rice grains cook deliciously from the inside without worrying about being dry and mushy because the steam will go out and not fall back into the rice. . This is one of the reasons why this rice cooker is more expensive from 2,000,000 VND to 25,000,000 VND.
