The standard of living is getting better and better, so whether it's a hotel or a small restaurant on the street, the business is becoming more and more prosperous. However, the business is good, but the attendant trouble also comes: the smoke exhaust of range hood and range hood pipeline in kitchen equipment is not smooth, resulting in the poor back kitchen environment and seriously affecting the health of employees. We summarized some reasons for the poor smoke exhaust effect of back kitchen kitchen.

1、首先規劃不合理：因在開業裝修時估計的就餐人員飽和值低于現今就餐飽和值，后廚工作量增加，多臺灶同時作業，原規劃風機轉數低，排煙量小，導致排煙不暢。解決辦法：在排煙口加裝風扇式四葉或六葉排煙風機，進步排煙量;或替換大風量風機。

1. First of all, the planning is unreasonable: because the estimated saturation value of diners during opening and decoration is lower than the current dining saturation value, the workload of back kitchen increases, multiple stoves operate at the same time, the originally planned fan speed is low and the smoke exhaust volume is small, resulting in poor smoke exhaust. Solution: install fan type four leaf or six leaf smoke exhaust fan at the smoke exhaust outlet to improve the smoke exhaust volume; Or replace the high wind fan.

2、然后設備陳舊老化：部分廚房設備中的舊式排油煙設備排油煙罩老化，導致煙罩漏風，排煙量下降;排煙風機老化導致轉速下降，排煙量下降，舊式排油煙設備的油煙管道都比較細(管徑約300mm*300mm),因長期積存油垢又不便利清洗，也同樣導致排煙效果不好。

2. Then, the equipment is old and aging: the exhaust hood of the old oil fume exhaust equipment in some kitchen equipment is aging, resulting in air leakage of the hood and reduction of smoke exhaust; The aging of smoke exhaust fan leads to the decrease of rotating speed and smoke exhaust volume. The oil fume pipes of old oil fume exhaust equipment are relatively thin (pipe diameter is about 300mm * 300mm). Due to the long-term accumulation of oil dirt and inconvenient cleaning, it also leads to poor smoke exhaust effect.

解決辦法：沒其他好辦法，查查終究哪的問題Z嚴峻，查查煙罩、煙道是否漏風，能夠緩和一些，假設還不行，一般風機的問題Z大，那有或許就得換了，假設說下降費用的話，排油煙罩能夠保留。

Solution: there is no other good way. Check whether the Problem z is serious after all. Check whether the smoke hood and flue leak. It can be alleviated. If not, the Problem z of general fans may have to be replaced. If the cost is reduced, the oil fume hood can be retained.

3、終究未守時清洗：油煙機在運用一段時間，油煙機葉輪、煙道大將粘有許多的油污，增加了葉輪的分量，這樣必然增加了風輪滾動動能，使電機起動電流加大。機構從前做過測試：長期未清洗的油煙機，在開機時的電流是正常值的3-6倍，這樣很簡略焚毀電機，所以守時清洗油煙機，對電機是一個很好的維護效果，能夠延伸油煙機的運用壽數。油污粘住電機轉軸，加大了磨擦力，使電機負荷加大——費電。

3. After all, it is not cleaned on time: after the range hood has been used for a period of time, there will be a lot of oil stains on the impeller and flue of the range hood, which will increase the component of the impeller, which will inevitably increase the rolling kinetic energy of the wind wheel and increase the starting current of the motor. The organization has done tests before: the current of the range hood that has not been cleaned for a long time is 3-6 times of the normal value when it is started up, so it is easy to burn the motor. Therefore, timely cleaning of the range hood is a good maintenance effect for the motor and can extend the service life of the range hood. Oil stains stick to the motor shaft, increasing the friction force and increasing the motor load - electricity consumption.

濟南酒店廚房排煙罩清洗的好處：

Benefits of cleaning the kitchen smoke hood of Jinan Hotel:

1.酒店大型油煙機排風渦輪定期清洗可提高排風效果，因為大型風機的千葉渦輪葉片本身間隙就很小，一旦沾滿油膩排煙效果會大打折扣。

1. Regular cleaning of the exhaust turbine of the hotel's large range hood can improve the exhaust effect, because the clearance of the thousand blade turbine blade itself of the large fan is very small, and the smoke exhaust effect will be greatly reduced once it is greasy.

2.油煙凈化器定期清洗，因為油煙凈化器作為排煙系統的重要部分，它是集中油膩Z多的地方。凈化器清洗干凈不但利于廚房排煙流暢，更能解除消防隱患。

2. The oil fume purifier shall be cleaned regularly, because the oil fume purifier, as an important part of the smoke exhaust system, is a place with a lot of grease. Cleaning the purifier is not only conducive to smooth smoke exhaust in the kitchen, but also can eliminate fire hazards.

3.排煙主管道，特別是主排煙管水平線低處就是油煙屯積的地方。由于飯店廚房設備的油污所引發的火災事故已經不勝枚舉，希望廣大業主不可掉以輕心。

3. The main smoke exhaust pipe, especially the lower part of the horizontal line of the main smoke exhaust pipe, is the place where oil smoke accumulates. The fire accidents caused by the oil pollution of hotel kitchen equipment have been numerous. I hope the owners can't take it lightly.
