The working principle of the heating tube in the steam cabinet

The steam cabinet has many functions, such as steaming rice, steamed buns, Mantou, and disinfection with the steam cabinet. The steam cabinet adopts a balanced gas distribution structure, where steam is evenly distributed to each food basin, and the upper and lower basins of food are cooked at the same time. This structure allows for the full utilization of steam, prevents steam loss, and allows the heat of steam to be fully transferred to the food, maximizing energy savings. Choosing a qualified heating tube with good power is particularly important in this regard. The working principle of the steam cabinet is a simple temperature control circuit, which uses a temperature controller as a secondary circuit to control the AC contactor to supply power to the heating tube. The quality of the heating pipe in the steam cabinet directly reflects whether the heat of the steam is lost. Is the food in the steamer delicious.

1. The so-called grasp of moderation is very important. If everything exceeds a certain degree, it will inevitably achieve qualitative change. The same applies to stainless steel electric heating pipes. If the power setting of the stainless steel electric heating pipe is too high, the surface load is too large, and the internal temperature is too high, it can easily cause internal expansion of the electric heating pipe, leading to pipe explosion. As for the rationality of power setting,

2. The second possibility is the issue of magnesium oxide powder, which can be divided into many types, with the best being modified magnesium oxide powder with high temperature resistance. If low-quality magnesium oxide powder is used, the stainless steel electric heating pipe will also experience internal expansion during operation, resulting in pipe explosion.

3. The third possibility is that the external material of the electric heating tube may be the thin wall thickness of the tube, or it may be a stainless steel slotted tube, which makes the electric heating tube prone to cracking.

4. The fourth possibility: it is the customer's own problem. The water used for heating stainless steel electric heating pipes may mostly be groundwater or tap water, with many impurities that are prone to scaling. If the scale is too large or too thick, it will cause the internal temperature of the electric heating pipe to not diffuse, leading to the explosion of the electric heating pipe.
