At present, the inner liner materials of electric stews on the market mainly include the following:
1, aluminum material
The inner container made of aluminum is characterized by uniform heat conduction and easy molding. The inner container made of this material is widely used in some mid-range electric cookers, but aluminum is easy to oxidize, so the electric cooker made of this material cannot directly contact with the ingredients, and a protective film must be coated on the surface. The thickness of aluminum liner of electric cooker is generally between 1.5mm and 1.6mm, and the plate is thick. Although aluminum is soft, the quality of thick aluminum liner is very good.
2, stainless steel material
The biggest feature of stainless steel liner is its strong corrosion resistance. This material is very common and has a good effect. The stainless steel plate of the best electric cooker household appliances is generally 304 stainless steel, and the poor stainless steel is 202 stainless steel. The cost of good stainless steel material is high, so the price of stainless steel liner is relatively high. Care should be taken to avoid buying inferior stainless steel stews with low price. The disadvantage is that the surface is sticky and easy to stick to the pot.
3. Ceramic material
Common ceramic electric stews, such as purple casserole and white porcelain pots, are all listed here. Ceramic is a kind of safe inorganic material, which is rich in certain trace elements. Cooking food with it is beneficial to people's health. The surface of the ceramic electric cooker is wear-resistant, acid-and alkali-resistant, corrosion-resistant, and has good thermal insulation performance. The cooked food is fresh and delicious, and the taste is good. However, ceramic electric cookers generally use slow fire to cook food, which takes a long time and is easy to be damaged when bumped.
4. Composite material
The composite materials used as the inner liner of electric stews are generally two-layer composite inner liner with outer aluminum and inner steel and three-layer composite inner liner with outer aluminum and inner steel. This kind of inner liner combines the performance advantages of aluminum and steel, which not only solves the problem of excessive viscosity of steel, but also solves the problem that aluminum can not directly contact food. However, the cost of this complex electric cooker with compound liner is high, so the price of electric cooker will increase accordingly.
Extended data
Stewing skills of electric cooker;
1, understand the nature of ingredients, and choose suitable stalls to stew and cook ingredients. For example, white meat such as chicken, duck and fish can be stewed quickly, and red meat ingredients such as cattle and sheep can be stewed slowly, making the food softer and more delicious.
2. Any food can be stewed for a good taste, but it should be noted that the water level in the pot must be kept above 50% of the volume of the inner pot to prevent dry burning.
3. When using the heat preservation function of the electric cooker, the continuous heat preservation time is controlled within 24 hours, which can avoid the food from being too cooked and rotten for a long time, affecting the taste, and can also avoid the damage caused by the electric cooker working for a long time.
