Commercial induction cooker purchase strategy

As a convenient and safe mobile stove, the commercial induction cooker is an indispensable small electrical appliance in many families. In general, many consumers who buy induction cookers will be distracted by the fancy propaganda of the manufacturers. The price of induction cooker ranges from tens of yuan to several hundred yuan. Why is it expensive? Why are cheap induction cookers so cheap? Only by understanding these problems can we choose the right induction cooker according to our needs.

brand

Before choosing a specific product, you must first choose a few big brands. Big brands need to maintain their own brand image and strive for excellence in product quality. However, some small manufacturers will not worry so much, and product quality is difficult to guarantee. At the same time, after-sales is also a key point. Big brands are relatively complete in terms of after-sales service, which solves our worries. However, small manufacturers often cannot provide corresponding maintenance services, so when purchasing, try to choose a large-brand induction cooker, whether it is product quality or after-sales service, we are more at ease.

Panel

At present, the panels of induction cookers on the market are divided into two categories: imported and domestically produced. In terms of quality: Japanese NEG ceramic panel = German Schott panel> domestic A, B, C three-level ceramic panel and black crystal (microcrystalline) panel.

There are two main types of domestic panels: black crystal panels and ceramic panels. Ceramic panels were popular in the past few years, but now they are relatively rare. Generally, the price of induction cookers using this type of panel is relatively low. Ceramic panels are divided into three grades: A, B, and C. If you must choose this type of panel, it is recommended to choose A grade, which has higher stability and is not easy to change color after long-term use. The black crystal panel uses glass-ceramics, which is a kind of black glass. The cost is higher than the A-grade ceramic panel, but it has higher hardness. It is also the panel used by mainstream products on the market.

Imported panels are famous for NEG from Japan and Schott from Germany! Both of these panels have the advantages of no impurities, no discoloration, low magnetic field line damping coefficient, good heat insulation performance, high strength, high hardness, and low thermal expansion and contraction coefficient. Therefore, the induction cooker using this type of panel has the advantages of thermal efficiency, insulation and protection. Penetration performance, product performance and long service life have been greatly improved.

Wire reel

The wire reel is one of the important parts of induction cooker heating. The larger the wire reel, the larger the heating area, and the smaller the wire reel, the smaller the heating area. The heating area is large, the temperature rises quickly, and the heating is even; the opposite is true if the heating area is small. The diameter of the mainstream spool is 150mm-180mm, and the diameter of a few product spools can reach 200mm. A larger coil disk represents a larger heating area, more uniform heating, and can also reduce the heating time of the whole pot. However, a larger coil disk means higher costs. In the production process, the wire reel is wound around the wire reel in turns, and the longer the circumference of each turn, the required wire will rise exponentially.

The small heat generated by the coil is concentrated on the bottom of the pot, which will cause the bottom of the pot to be heated and expand, and the surrounding pot body is cooled, and does not expand with it, so that the hoop will cause the heating part of the bottom of the pot to only protrude. But when it cools, the elasticity of the iron is not good, the shrinkage is shrinking, and the convex shape is not restored. This pulling causes the middle to crack.

Function

There are many types of induction cookers on the market and more and more functions, but in fact, products with more functions are not better. The induction cooker is generally used to boil water, stir-fry, heat rice, and eat hot pot! These operations only have different requirements for temperature. The heating principle is the same. Don’t be fooled by the rhetoric of shopping guides when purchasing. Many so-called multi-functions are just different temperature adjustments and have no practical meaning, but they have to be for this. Spend a lot of money.

Heat dissipation

The induction cooker generates a lot of heat when cooking, so the heat dissipation problem cannot be ignored. The high-quality induction cooker adopts imported DC cooling fan, which has good heat dissipation and low noise, which helps to prolong the service life of the induction cooker. In addition to choosing a fan with high wind power, you also need to check whether the air outlet is smooth. A horizontal exhaust outlet design is recommended. This kind of heat dissipation effect is good, and the electronic components can be used for a longer period of time.
