How much do you know about the inside of the cooker?
Aluminum inner container: aluminum is uniform in heat conduction, easy to form, beautiful, and can be combined with other metals or alloys. It is the main material of mid-range cooker. But the aluminum liner can not touch the food directly, so it must be protected by surface. The aluminum plate making liner for 3003 aluminum plate, electric rice cooker liner ordinary 3L and 4L specifications, with the thickness of sheet metal 1.51.6mm, 5L, 6L 1.82.2mm pot multi-purpose plate.In the manufacture of aluminum inner liner, thinning and stretching technology is often used. This technology can keep the thickness of the pot and the bottom of the pot. Under the premise of saving material, the inner liner looks thicker.Liner popular words: thick pot""Thick pot" liner means that the bottom of the pot and the pot wall are made of thicker metal materials. Because the food is heated by the inner liner, the heat delivered is proportional to the heat transfer area under certain conditions, that is, the effect of the heat transfer of the liner is proportional to the thickness of the inner liner. Only when the liner thickness reaches 3 4mm, can fully meet the needs of cooking heat transfer channel, achieve a luxurious family "rice and meat fragrance" "Ding" effect. If the thickness of the liner does not reach 3 - 4mm, it can not be called a "thick pot"".This is why the real "thick kettle" inner cooker or an electric pressure cooker will not be cheap, because if it is really a "thick kettle, thick bile" products, raw materials of the liner, the liner can be used to 3mm and 4L plate 3mm, 5L or L or more will use 3 - liner plate 5mm, the manufacturing cost is much higher than ordinary liner.
The liner is directly contacted with the food, and it is the key factor to determine the quality of the rice cooker. Therefore, the liner naturally becomes the focus of the competition of each brand product in the market. Therefore, the rice cooker will market have so many objective: Tao Jing liner, liner space liner, shaped, thick black crystal crystal nano ceramic liner, liner, black crystal crystal Topaz hard liner, liner, liner, oxygen heizuan stainless steel etc..
In fact, so more than its name to liner, are due to the process of material and the interior surface of the liner, so what kind of liner is good or bad, is not what it is, but the key to see what it is made of material, how to process surface treatment of it?What material is the liner made of?The main materials for making the rice cooker inner liner are aluminium, stainless steel, composite multilayer materials and ceramics (purple sand).
