What is the size of the wok?

General household has 30 cm, 32 cm and 36 cm.

30cm: Suitable for about 3-4 people.

32cm: Suitable for 3-5 people.

36CM: generally used by 5-6 people. Domestic woks are generally 32cm or 34cm, so the wok is easy to use and has enough carrying capacity.

The size of domestic wok is generally 24-30cm. Iron pot is the most commonly used cooker in the family, and there are also some problems that need attention in the purchase and use.

Ordinary iron pots rust easily. If the human body absorbs too much iron oxide, that is, rust, it will do harm to the liver. Experts say that iron pots rust easily and are not suitable for holding overnight food. At the same time, try not to use an iron pot to make soup, so as to avoid the oil layer on the surface of the iron pot disappearing and rusting. When brushing the pot, use detergent as little as possible to prevent the protective layer from being brushed off.

Pot selection for kitchen utensils:

1. pressure cooker: pressure cooker with pressure limiting device, safety pressure protection device and pressure protection device for opening and closing lid shall be purchased. In particular, there are a large number of old-fashioned pressure cookers on the market without pressure protection devices for opening and closing lids, which have been eliminated and do not meet the requirements of current national standards. Also buy on demand.

Aluminum alloy pressure cooker has fast heat conduction and uniform heating; Stainless steel pressure cooker is beautiful, clean and wear-resistant, but it is slow in heat conduction, concentrated in heating and easy to paste the bottom. However, at present, some stainless steel pressure cookers have added composite bottoms to improve their performance.

2, the iron pot is thick and thin, and the thinner is better. Some iron pots may be thick on one side and thin on the other, which is caused by the dislocation of models. This pot with uneven thickness is not good. When buying, you can turn the bottom of the pot upside down, put your finger against the concave surface of the pot and knock it with a hard object. The louder the pot rings, the greater the vibration, the better. This method can also be used to check whether there are cracks in the pot.

There are two kinds of aluminum pot: refined aluminum (soft aluminum) products and cast aluminum (hard aluminum) products. The materials are aluminum and aluminum alloy. Surface colors can be divided into white, light yellow and other colors. White aluminum products are divided into casting and stamping. After turning and mechanical polishing, the surface of cast aluminum products is white, but the metal structure is loose and there are some casting defects.

4. The quality of stainless steel pot depends on the bottom of the pot, and the aluminum layer thickness of the three-layer composite bottom should be evenly distributed. The structural design of the pot cover should be reasonable and the sealing performance should be good. The slightly raised lid design allows water to circulate naturally, and heat is not easily lost due to sealing.
