One, stainless steel steamer or aluminum steamer which is better
Unless it is heated on an induction cooker, the steamer is best made of aluminum, because the aluminum pot conducts heat High rate, save gas cost. But the main problems of aluminum pans are low strength, easy deformation at high temperature (such as when frying at high temperature), and aluminum may dissolve into the soup (such as when soup is simmered for a long time), causing damage to the human body. But as a steamer, as long as you don’t boil the water dry, these problems don’t exist.
However, the current steamer is generally made of stainless steel. The thermal conductivity of austenitic stainless steel is only 1/3 of that of iron and only one-tenth of that of aluminum. It is conceivable that steaming vegetables in a stainless steel pot costs more gas. However, in general, stainless steel pots have a longer life than aluminum pots, are safer when stewing and soup, and have the advantages of strong applicability, so you can also consider buying a stainless steel steamer.
Second, what is the best material for the stainless steel steamer
The stainless steel steamer is made of steel, magnetic and non-magnetic. Many people are misled. Magnetic ones are easier to rust than non-magnetic ones. This is too general to understand. In fact, with or without magnetism, it is not equal to the quality of rust prevention. It mainly depends on the material of the steel. The non-magnetic ones are mainly 201 and 304 materials, and the magnetic ones are mainly 430 and YH21CT. The 430 stainless steel with magnetic is slightly more rust-proof than the non-magnetic 201 stainless steel, followed by YH21CT, and the 304 stainless steel is a non-magnetic stainless steel that adopts the American standard. It is used for austenitic, medium and high-grade steamers.
3. How to choose a stainless steel steamer
1. Food grade
In our choice When buying a stainless steel steamer, pay attention to whether the material meets the standards of food-grade tableware, which can prevent harmful substances from damaging our health.
2. Anti-corrosion
When purchasing a stainless steel steamer, we can choose a 304 food-grade stainless steel steamer with better corrosion resistance. Usually there will be relevant signs printed on the surface of the steamer.
3. Is it magnetic?
Usually we consider the problem of rust when we buy stainless steel steamers. Generally, stainless steel steamers without magnets are more Better, the magnetic ones are easier to rust.
4. Number of layers
We should not ignore the number of layers of the steamer. According to the needs of usual cooking, we can choose single or layered ones Large number, easy to store, more space-saving. If you usually cook a lot, you can also choose a multi-functional one, so that steaming, boiling, and stewing can be done at the same time, saving time and gas.
5. Transparent pot cover
When we steam things, using a transparent pot cover is more convenient for us to observe the degree of cooking of the food at any time, which is convenient for us Flexible operation.
6. Handles
Generally, one of the handles of the steamer can be tightened, and the other is fixed. There is no way to adjust it yourself, so in order to Our use is safe, we try to buy the kind of fixed and better, all-inclusive handle.
7. Thickness of the bottom of the steamer
When we buy a steamer, it is best to choose a steamer with a double bottom, because we choose a steamer with a double bottom. The steamer needs to be used for a long time, and the single-layer bottom is more likely to burn out or burn the pot.
