Heat preservation mechanism of restaurant stews

Use an incubator. Five-star hotels do this. Their names are warmers and incubators in Chinese. Of course, this word is too broad. I think the vertical incubator in a five-star hotel is more like a steamer. Only steam can be used for heat preservation or heating, and the maximum is several hundred degrees. Its panel is usually a knob panel.

There is also a hotel food insulation tool. I have to say that the principle of multifunctional oven is to heat food through hot air circulation. Even if the cold dishes are cooked in hot air for a few minutes at a critical moment, it is no problem. The maximum temperature is over 400 degrees Celsius, and there are various circulating air heating modes, including steam mode, barbecue mode and heat preservation mode. Its control panel should be an embedded computer panel. Multifunctional oven is very expensive, on its embedded computer panel. None of the other components are technological products.
