Hotel kitchen hood system to note what

Long Xiangjiang Anhui equipment Cold plant: Professional offers cafeteria Houchu {} {galvanized stainless steel exhaust hood exhaust hood exhaust pipe}} {designed the installation. Material mainly: two galvanized steel and stainless steel, according to customer needs processing of semi-finished products, assembled at the site, so not only convenient, and most importantly save a lot of transportation costs. Advanced production technology, good looks, economical and practical. Long Xiangjiang Anhui cold kitchen equipment factory, in the ventilation duct design, production, installation, introduction of advanced air duct automatic production line cutting, shearing, locking machine, beading machine, rounded machine, bending machine, French Portland molding machines, more than ten sets of ventilation equipment processing machinery. Kitchen hood system needs attention to what? Kitchen hood system, hoods cover mouth wind speed of not less than 0.5m / s. 2, determine the amount of exhaust fumes from the kitchen: Chinese Kitchen: L = 40-50 (times / h) Western kitchen:. L = 30-40 (times / h) catering:. L = 25-35 (times / h) 3, the horizontal segment kitchen exhaust pipe exhaust pipe should not be too long  general level of the maximum distance should not exceed 15m and have a slope of more than 2% of the level of the end of the union set up to facilitate the clean-up grease. Exhaust speed according to specifications of not less than 10m / s wind speed is too low to prevent the oil attached to the hood flue  connected manifolds should be located air flow control valve 4, exhaust fan: common exhaust fan axial fan wind chassis and centrifugal fans 3 kinds 1 axial fans used more often before but because of the small total pressure after installing smoke purifier rarely used. 2 full pressure moderate wind chassis air flow can be adjusted and are often used in low noise centrifugal fan 3 in fume hoods from the discharge opening from the middle of the kitchen exhaust system, full pressure and air volume can be adjusted, but often needs to be done because of the noise the larger drop noising. When the kitchen at the bottom of the building when it is the exhaust fan on the roof Yee one can reduce interior noise pollution at the same time the exhaust duct in the vacuum state can avoid the smell of overflowing. Fan mounted on the roof when the general selection centrifugal fan.
