Automatic Cleaning Ventilation Hood Manufacturer
-- Steady & Reliable Manufacturer --
Introduction
An automatic cleaning ventilation hood combines the primary function of a commercial kitchen exhaust hood — capturing and exhausting cooking fumes, steam, and heat — with an integrated automated cleaning system that removes accumulated grease from the hood interior on a scheduled cycle. This integration eliminates the separation between ventilation equipment and cleaning equipment that exists in conventional kitchen fit-outs, where the hood is a passive capture device and cleaning is performed manually as a separate, disconnected task.
Yuede's automatic cleaning ventilation hoods are available in wall-mount, double-island, and low-proximity configurations to suit different kitchen layouts and cooking equipment arrangements. Each model incorporates a stainless steel spray nozzle network within the hood plenum, connected to a heating and pressurization unit and controlled by Yuede's programmable cleaning controller. The hood captures fumes during cooking service hours and automatically cleans itself during the post-service window — combining two critical kitchen management functions in a single, seamlessly integrated unit.

Application
- Full-Service Restaurant Kitchens: The most common application — wall-mounted automatic cleaning ventilation hoods over cooking ranges, wok burners, fryers, and grills in restaurants where daily cleaning after service is the operational requirement.
- Hotel Banquet Kitchen Production Lines: Large banquet kitchen production lines with extended cooking ranges (3,000–6,000 mm) benefit from automatic cleaning hoods that manage the heavy grease load generated during high-volume banquet production efficiently.
- Open Kitchen Restaurant Concepts: Diners in open kitchen restaurants can see the kitchen equipment. Automatic cleaning ventilation hoods with brushed stainless steel finishes and LED lighting present a professional, hygienic appearance while handling grease management invisibly.
- Fast Food & Quick Service Restaurants: QSR kitchens with fryers and griddles generate consistent high grease loads at predictable times. Automatic cleaning cycles timed to run between breakfast and lunch service, and again after dinner close, keep grease management in step with the cooking schedule.
- Central Production Kitchens: Central production kitchens supplying multiple retail locations operate long daily shifts and require exhaust hoods that can be cleaned reliably without adding to the operational burden of a skeleton overnight cleaning team.
- Q: What is the difference between an automatic cleaning ventilation hood and a standard ventilation hood with a separate cleaning system?
- A: An integrated automatic cleaning ventilation hood has the spray nozzles, water supply connections, and drain integrated within the hood body during manufacturing — the cleaning system is purpose-built for that specific hood geometry. A separate retrofit cleaning system added to a standard hood requires additional installation work and may not provide complete coverage of all grease-contact surfaces. The integrated approach generally delivers more thorough and reliable cleaning results.
- Q: Does the hood need to be a specific height above the cooking surface?
- A: Standard installation height is 650–800 mm from the cooking surface to the bottom of the hood for wall-mounted units. Low-proximity models can be installed 500–600 mm above the cooking surface for improved capture efficiency with lower exhaust airflow rates. The correct height depends on the type of cooking equipment below and local ventilation code requirements. Yuede can advise on optimum hood height based on your equipment list and local standards.
- Q: Can I order an automatic cleaning ventilation hood with supply air capability?
- A: Yes. Yuede offers supply air integration options including short-circuit supply (air discharged horizontally from the front face of the hood), perforated front discharge, and separate supply plenum configurations. Supply air integration reduces the net exhaust air requirement and associated make-up air heating/cooling cost, which is particularly valuable in climates with extreme outdoor temperatures.
- Q: How long does installation take?
- A: For a standard single-hood installation in a new kitchen fit-out, mechanical installation typically takes 1–2 days plus commissioning of the cleaning controller and plumbing connections. Retrofit into an operating kitchen requires scheduling with kitchen management to allow access — typically a weekend installation with minimal disruption to service. Complex multi-hood systems may require a phased installation over several days.
