How about the range hood in the hotel kitchen? Matters needing attention of kitchen range hood

Now people will use some range hoods that can be lit at home. It's easy to buy in the store, but there are many aspects of what range hoods to use in other places. The range hood in our hotel kitchen is very particular. What is the working principle of the kitchen range hood in our hotel, and what are the precautions?

Introduction of range hood in hotel kitchen

1, range hood, also called range hood, is a kind of kitchen appliance to purify the kitchen environment. Installed above the stove of a healthy and energy-saving range hood in the kitchen, it can quickly pump away the garbage burned on the stove and the oil fume harmful to human body generated in the cooking process, and discharge it outdoors, reducing pollution, purifying the air, and has the safety guarantee function of anti-virus and explosion-proof.

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

Second, the working principle of the range hood in the hotel kitchen

The range hood is installed on the upper part of the cooker, connected with the power supply of the cooker, and drives the motor to make the wind wheel rotate at high speed, so that a negative pressure zone is formed in a certain space above the cooker, and the indoor oil fume gas is sucked into the cooker, filtered by the oil net, separated for the first time, and then enters the air duct of the cooker, and separated for the second time through the rotation of the impeller. The oil fume in the air cabinet is subjected to centrifugal force, and the oil mist condenses and fuses into oil droplets, which are collected in the oil cup through the oil circuit.

Third, the advantages of the kitchen range hood in the hotel

1, which will not lose heat energy and make the combustion more complete.

The installation height of the top-suction range hood conforms to the national standard, and it will not interfere with the normal work of the gas stove during use.

2, in line with the principle of air convection, oil smoke absorption is smoother.

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

3, double air inlet, better oil smoke absorption effect.

In general, the gas stove has two burners, and the range hood needs two air inlets corresponding to the two burners of the gas stove to achieve better oil smoke absorption effect.

4. Double-layer oil screen has better oil smoke separation effect.

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

Four, the hotel kitchen lampblack machine matters needing attention

1, required performance parameters: exhaust air volume, wind pressure, noise and voltage attack rate. When purchasing range hood products, there are four required product performance indicators: 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 size of the air inlet 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 300 square centimeters (about 600 double air inlets), while the air inlet of the side range hood is nearly 2000 square centimeters, and the width is better than 65cm.

3. Panel materials are very important.

Many people ignore the material of the range hood when buying. 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 friends must look at the precautions of these kitchen range hoods to ensure our safety.
