What material is good for rice cooker liner and which material is good for rice cooker liner?

1. Ceramic liner.

Ceramic rice cookers are mostly made of ore and sand and gravel, which is one of the safe inorganic materials. It is rich in a variety of trace elements such as iron, zinc, and calcium that are beneficial to human health. The cooked food has a good taste, and the surface is super hard and wear-resistant, acid-alkali resistant and corrosive, and has good thermal insulation performance.

However, it is less thermally conductive and heats up more slowly, but it is worth waiting a few more minutes for the sake of deliciousness.

However, the ceramic rice cookers on the market are mixed, not all self-proclaimed "clay pottery" rice cookers are made of natural organic clay, when purchasing, it is necessary to carefully distinguish whether there is a chemical coating, it is best to choose products produced by well-known merchants, so that the after-sales will be more secure.

2. Aluminum liner.

In fact, at present, the mainstream production material of domestic rice cooker liner is mostly aluminum. This is because the aluminum liner contains metallic aluminum, which conducts heat evenly and is more cost-effective to manufacture. The appearance is also relatively beautiful, and it can be compounded with other metals or alloys.

However, aluminum products have certain damage to the human body.

Although it is negligible, when the temperature is too high and under acidic conditions, the coating inside the rice cooker may peel off, and the chance of aluminum seeping into the food will increase. Among all kinds of aluminum products, cast aluminum products have the largest aluminum capacity, followed by cooked aluminum, and aluminum alloy has almost no dissolution, so when buying aluminum rice cookers, it is better to use aluminum alloy.

Hello, landlord:

Now the more common on the market is the use of general alloy aluminum liner rice cooker, the thickness of this liner is generally less than millimeters, the surface treatment technology mostly uses ordinary non-stick coating. This kind of liner will generally be very effective at the beginning, no pot, will not stick to the pan, but after a long-term high temperature action, it is easy to deform, and the non-stick coating on the surface is easy to fall off after brushing, and more seriously, these peeling coatings and the aluminum layer exposed after the coating falls off are easy to dope into the food, which has adverse effects on the human body.

Another common one is a rice cooker made of stainless steel, which is more expensive than an alloy aluminum liner. Stainless steel rice cookers don't have to worry about the non-stick coating falling off, but the cleaning of stainless steel liners is indeed more troublesome, and it is often difficult to remove the pots left after cooking.

In view of the defects of the above two kinds of inner tanks, some large brand manufacturers began to research, such as the United States launched a black crystal inner rice cooker, using alloy aluminum with a thickness of 2 mm, and using aerospace technology oxidation process, not only to make the strength higher, wear resistance and non-stick are also greatly improved; Supor has launched a rice cooker with ceramic crystal liner, applying ceramic maturity technology to the rice cooker liner, so that the traditional chemical surface treatment process turns to natural surface treatment, and this pure natural inorganic substance completely avoids the secondary pollution of paint and metal liner in the cooking process for a long time. When buying a new rice cooker, many consumers tend to prefer this rice cooker with a new process.

Overall, if you are financially affluent and are more concerned about the quality of your food and quality of life, a rice cooker with ceramic liner and black crystal liner is a good choice. If you are very experienced in cooking rice, you will not leave a pot on the inner bowl after cooking, and you will be able to use a stainless steel rice cooker with a relatively easy facet.

The purple sand liner is a very healthy rice cooker liner.

The types of rice cooker liners are as follows:

1.Aluminum liner. The rice cooker with aluminum liner conducts heat evenly, is easy to form, and has a beautiful appearance.

However, the aluminum rice cooker liner cannot directly contact the food, so the surface must be treated with a layer of surface protection. During the manufacturing process, the aluminum rice cooker liner will be stretched and thinned. This technique keeps the thickness of the aluminum rice cooker liner consistent between the rim and the bottom.

Such a design not only saves material, but also makes the liner look thicker.

2.Thick kettle liner. The thickness of the pot refers to the fact that the wall and bottom of the pot are made of metal.

During the heating of food, the amount of heat transferred is directly proportional to the area where the heat is transferred. And only when the thickness of the rice cooker liner reaches 3-4mm, can the food be heated normally and meet the heat required for cooking food. Therefore, if the thickness of the inner tank does not reach 3-4mm, it cannot be called a real "thick kettle".

3.Honeycomb lining. The honeycomb liner refers to the inner liner of the rice cooker, which is designed to resemble a honeycomb for demining. In the thermal effect particle design of the inner tank, this design can make the heat conduction more sufficient. Compared to ordinary flat liners, honeycomb rice cooker liners can improve the energy efficiency of heating.

4.Stainless steel liner. The best stainless steel liner is made of 304 plate, which has good resistance to intergranular corrosion and corrosion.

Generally, the 4L stainless steel liner is about the plate, and the 5L and 6L liners are about the plate. Poor quality stainless steel liners will be processed with 202 plates, and the anti-rust ability of 202 plates is slightly worse than that of 304 plates. The lower stainless steel lining is made of 201 plates.

At present, the dissolution of 201 stainless steel harmful metals that can be bought in China is generally difficult to meet the national sanitary standards for stainless steel tableware containers, so the most extremely low stainless steel liner rice cooker must be carefully chosen.

5.Double-layered backing. Although the stainless steel liner has good corrosion resistance, it has poor thermal conductivity, and the double-layer bottom liner can just make up for this defect. The double backing will be made on the stainless steel plate, and the way to deal with it is the double backing.

6.Ceramic (purple sand) liner. Purple sand is a pure pottery and a safe inorganic material.

Zisha liner is a healthy rice cooker liner. Purple mud contains calcium, zinc and other trace elements required by the human body, which has a good nursing effect on the human body. In addition, purple mud is also rich in iron.

The food made by purple sand tastes good. Moreover, the surface of purple sand is wear-resistant, corrosion-resistant, acid-alkali resistant, and the thermal insulation performance is also very good.

The best and healthiest inner liner of the rice cooker is as follows:

1. Ceramic crystal liner: The rice cooker of ceramic crystal liner is known as a pure natural inorganic, it does not use coatings, will not bring harm to the human body, and has good acid and alkali resistance and strong corrosion, good thermal insulation performance, etc. However, it heats up slowly, has low thermal efficiency, and is easy to break.

2. Composite liner: The composite multi-layer material liner is generally mixed with pure copper, with five layers of different materials from the inside to the outside, which integrates the advantages of each material, has strong thermal conductivity, and is not easy to stick to the pan, but the cost is also relatively high.

3. Black crystal liner: alloy aluminum with a thickness of 2 mm is used, and the oxidation process of aerospace technology is adopted, which not only makes the strength higher, but also greatly improves the wear resistance and non-stickiness.

Rice cooker buying tips.

First of all, according to their own economic strength to choose some excellent brand products, good brands in quality service and after-sales guarantee are good, so that consumers can buy at ease. Secondly, you can choose a rice cooker that combines multiple functions, which can not only save money, but also effectively use the space in your home.

The rice cooker not only has the function of cooking rice, but also can make cakes, and some pressure cookers can cook chicken without water. Mausoleum type.

The better rice cooker liners are: first, the aluminum liners, which are better to ensure the uniformity of heat conduction; Second, the stainless steel liner has high durability, no coating on the surface, good oxidation resistance and corrosion resistance; Third, the composite multi-layer material liner has good thermal conductivity and is not easy to stick to the pan; Fourth, the ceramic liner can not only bring anti-oxidation and corrosion-resistant effects, but also have a certain degree of thermal insulation.

1.Aluminum lining.

The aluminum liner has good thermal conductivity and is easy to form, and the output heat is relatively uniform, so that the subsequent internal food is heated evenly. The overall appearance of the aluminum liner is also relatively beautiful. When such linings are manufactured, other metals or alloys can be added for compounding.

It is a traditional liner material, which is more suitable for stir-frying. But be careful not to buy pure aluminum liners, try to choose coated ones, so that the service life of aluminum liners will be longer, and there will be no harm to the human body.

2.Stainless steel lining.

The stainless steel liner has high durability, uncoated surface, high safety performance, and also has certain anti-oxidation and anti-corrosion functions. There is no coating, so the coating will not come off in the subsequent heat conduction, and it is easy to stick to the pan. Therefore, everyone should soak it in water after use, and it will be more convenient to clean up.

And it should be noted that the stainless steel liner should be made of 304 food-grade stainless steel, which can meet the food-grade requirements.

3.Composite multi-layer material lining.

This kind of inner tank is a fusion of various materials inside, the outside is composite steel, and the inside is a non-stick coating material, with good thermal conductivity and will not stick to the pan. Due to the different composite materials added, their names are also different, such as the common black crystal liner, Tao Jing liner, etc. , all of which belong to the category of composite multi-layer liners.

For the black crystal liner, the surface of the inner tank is made of alloy materials with higher strength, which will have higher wear resistance and is easier to clean, while the surface of the Taojing inner tank is covered with a layer of natural ceramic material, which is scratch-resistant and wear-resistant.

4.Porcelain lining. Ceramic liner is a natural inorganic material that has advantages in oxidation resistance and corrosion resistance, and has certain thermal insulation properties.

In addition to being used for cooking, it can also be used to make soup, which can effectively ensure the nutrients in the food. Moreover, the cooked food tastes good, is a relatively safe inorganic material, and will not have much impact on human health. Moreover, this material has high hardness and resistance to acids and alkalis.

The inner liner of the metal rice cooker we usually use is made of pure aluminum or alloy aluminum. Aluminum is not only not needed by the human body, but also very harmful to the human body. If the human body consumes too much aluminum, it will form a variety of serious diseases.

The purple sand not only does not contain elements harmful to the human body, but also contains a variety of trace elements needed by the human body.
