Selection of the Heating Tube of the Steamer

The heating tube is a seamless metal tube (carbon steel tube, titanium tube, stainless steel tube, copper tube) filled with electric heating wire, the gap part is filled with magnesium oxide powder with good thermal conductivity and insulation, and then it is processed into Various shapes required by users. The heating tube has the characteristics of fast heat response, high temperature control accuracy, and high comprehensive thermal efficiency. High heating temperature means that the maximum task temperature of the heater design can reach 850°C. The medium outlet temperature is average, and the temperature control accuracy is high.

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.

Quartz heating tube is a special process of opal quartz glass tube, equipped with resistance composite material as the heating element, because opal quartz glass can absorb almost all the visible light and near-infrared light radiated from the heating wire, and can convert it It is far infrared radiation. Fast heating and good thermal stability, mainly suitable for relatively small ovens.

The mainstream steam oven heating tube is made of 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. 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.
