It should be noted that the range hoods in hotels are often large-scale equipment. The structure of this type of range hood is very complex, with many parts and components, and various circuits are intricately intertwined. If you are not a professional cleaning and maintenance personnel for large-scale range hoods, it is absolutely forbidden to dismantle this type of range hood privately. For cleaning of range hoods in large hotels, you can choose after-sales service or you can choose to have professionals do the cleaning. Pressure cooker steam flushing method. Boil cold water in the pressure cooker. When steam is continuously discharged, remove the pressure limiting valve, turn on the range hood, and aim the steam column at the rotating fan blades. As high-temperature steam continuously rushes into the fan blades and other components, the oily wastewater will flow into the waste oil cup until there is no oil in the oil cup. Soapy surface application method. Make the soap into a paste, and then apply it on the surface of the impeller and other components. After the range hood has been used for a period of time, remove the impeller and other components, wipe them with a rag, and the oil stains will fall off. Detergent and vinegar soaking method. Remove the impeller of the range hood and soak it in a basin of warm water mixed with 3-5 drops of detergent and 50 ml of vinegar. Soak it for 10-20 minutes, then wipe it with a clean rag. The housing and other parts are also cleaned with this solution. This method does not cause damage to human skin or corrosion to devices, and the surface retains its original gloss after cleaning. Use oil gourd cleaner. My family uses this brand. Another way is to disassemble the range hood and spray the fan blades with the range hood cleaner. To clean the large wind wheel, prepare some flour first and sprinkle the flour on the fan wheel so that your hands won't get dirty. Then use a small shovel or something to slowly scrape it down. Scrape and sprinkle some flour. This way it will be clean and you won't get oil on your hands. A little more flour is better. That's what I did. When cleaning, put the flour and the wind wheel on a piece of newspaper so you won't dirty the floor. In fact, sometimes at home we don’t think it’s a big deal if we don’t turn on the range hood when cooking. However, if we are in a large hotel, since there are many dishes to be cooked at the same time, the range hood is very important for large hotels. Moreover, since the hotel's range hoods are often in operation for a long time every day, the possibility of failure is very high. Therefore, the hotel's large range hoods must not only be cleaned and maintained regularly, but also require regular maintenance and inspection. |
