people now use some range hoods that can be lit at home. It is easy to buy them in stores, but there are many aspects about what range hoods are used in some other places. Our hotel kitchen range hoods are very particular. What are the working principles of our hotel kitchen range hoods and what are the precautions for them?

1. Introduction of the range hood in the hotel kitchen

1. The range hood, also known as the range hood, is a kitchen appliance for purifying the kitchen environment. It is installed above the range of healthy and energy-saving range hood in the kitchen, which can quickly pump away the waste burned by the range and the oil fume harmful to human body generated in the cooking process, and discharge it outdoors, reducing pollution, purifying the air, and having the safety guarantee functions of anti-virus and anti-explosion.

2. The range hood needs to be cleaned regularly. Simple cleaning can't get rid of oil stains. Professional cleaning agents must be used to clean the range hood.

second, the working principle of the kitchen lampblack machine in the hotel

The lampblack machine is installed on the upper part of the cooking range, and the power supply of the lampblack machine is connected to drive the motor, so that the wind wheel rotates at a high speed, and a negative pressure area is formed in a certain space above the cooking range, so that the indoor lampblack gas is sucked into the lampblack machine, filtered by an oil net, subjected to the first lampblack separation, and then enters the air duct of the cooking machine, and subjected to the second lampblack separation through the rotation of the impeller.

III. Advantages of the kitchen range hood in the hotel

1. The use will not lose heat energy and make the combustion more complete

The installation height of the top suction range hood meets the national standard and will not interfere with the normal work of the gas stove during use.

2. According to the principle of air convection, the oil fume can be sucked more smoothly.

Hot smoke will only rise, and in the process of air convection, the hot gas will always rise. According to this truth, the range hood should be installed on the upper part of the gas stove, so that the hot gas and oil fume can be discharged as soon as possible.

3. Double air inlets have better oil fume absorption effect

Generally, the gas stove has two burners, so it is necessary for the range hood to have two air inlets to correspond to the two burners of the gas stove to achieve better oil fume absorption effect.

4. Double-layer oil net has better oil fume separation effect

The so-called oil fume separation means that the oil fume is separated by a filter device before it enters the range hood, and the separated smoke is discharged outside to ensure a clean indoor environment; The oil is isolated from the outside of the range hood to ensure the performance and life of the range hood.

4. Precautions for range hoods in hotel kitchens

1. Performance parameters that must be seen: exhaust air volume, wind pressure, noise and voltage attack rate. When purchasing range hoods, there are four product performance indexes that must be seen: exhaust air volume, wind pressure, noise and voltage power, which play a key role in the use of range hoods.

2. Pay close attention to hardware indicators: air inlet size and filter plate design

The air inlet size refers to the plane area of the air inlet of the range hood. When purchasing products, we can roughly calculate this area. The traditional range hood is generally 311 square centimeters (the double air inlet is about 611), while the air inlet of the side range hood is nearly 2,111 square centimeters, and the width is better than 65cm.

3. The material of the panel is very important

Many people ignore its material when buying a range hood. In fact, the range hood has been exposed to the corrosion of lampblack for a long time and should be cleaned frequently. The material of the panel is very important. At present, the main materials of range hoods on the market are aluminum alloy, stainless steel and tempered glass.

We should pay attention to the use of kitchen range hoods in some hotels, because we know that the daily workload of kitchen range hoods in hotels is very heavy, so our friends must take a look at the precautions of these kitchen range hoods to ensure our safety.
