How to choose the heating tube of the steamer?
Today, let’s talk about the heating tube of the steaming oven, which has the most direct relationship with the steaming oven. After all, the main function of the steaming oven is steaming and roasting. To judge the quality of a steaming oven, the key is to look at the performance of the heating tube.
So what is the heating tube of the steamer? Generally speaking, the steaming oven has three groups of heating pipes, which are upper and lower heating pipes on the back, and the food is baked in all directions by the fan on the back.
The heating tubes of the steamer are mainly made of stainless steel and quartz tubes.
1. Quartz heating tube is an opal quartz glass tube processed by a special process, equipped with resistance composite material as the heating element, because opal quartz glass can absorb almost all visible light and near-infrared light radiated by the heating wire, and can make It is converted into far-infrared radiation.
Advantages: fast heating, good thermal stability
Disadvantages: easy to be brittle, difficult to reprocess, unable to accurately control temperature,
This type of heating tube is mainly suitable for relatively small ovens.
2. Now the mainstream steam oven heating tube material on the market is stainless steel. Mainly 301s stainless steel and 840 stainless steel. The stainless steel heating tube heats the fluid by forced convection.
Advantages: corrosion resistance, not easy to rust, good heat resistance, safety, strong plasticity
The difference between the quality of the stainless steel electric heating tube is mainly the nickel content. Nickel is an excellent corrosion-resistant material. After being combined with chromium in stainless steel, the corrosion resistance and process performance of stainless steel can be improved to some extent. Both 310S and 840 stainless steel tubes contain 20% nickel, which is an excellent material for heating tubes that has strong acid and alkali resistance and high temperature resistance.
In fact, 301s stainless steel is more suitable for steaming ovens than 840 stainless steel, and it has stronger corrosion resistance. You don't have to worry about being perforated and rusted by steam rust after being immersed in water for a long time. It is the most suitable baking tube for steaming ovens.
