Range hood purifier for catering

In today's rapidly developing catering industry, the issue of restaurant oil fume emissions has become a key focus of environmental regulation. A complete set of qualified range hood purifiers not only meets environmental compliance requirements, but also creates a healthy and clean kitchen environment for restaurants. As a Guanglan purifier with over ten years of experience in the industry, we will provide you with in-depth analysis on how to create an efficient and stable oil fume purification system from equipment selection, technical principles to post maintenance.

1、 The core components of a complete set of restaurant range hood purifiers

A complete oil fume purification system usually includes five modules: smoke hood, ventilation duct, oil fume purifier, fan, and silencing device. Among them, the oil fume purifier, as the core equipment, directly determines the purification effect. The Guanglan purifier adopts a dual-mode technology of electrostatic adsorption and mechanical filtration. Through a high-voltage electric field, the oil fume particles are charged and adsorbed on the electrode plate. Combined with a pre filter screen to intercept large oil particles, the purification efficiency can reach over 95%.

Key parameter selection guide:

2、 Why choose the complete solution of Guanglan purifier?

1. Customized design capability

For heavy oil fume scenarios such as Sichuan restaurants and barbecue shops, Guanglan provides a dynamic air volume adjustment system that monitors pipeline resistance in real-time through pressure sensors and automatically adjusts fan speed, achieving an energy-saving rate of up to 30%. After the installation of a certain chain hotpot brand, the annual electricity expenses decreased by 24000 yuan.

2. Intelligent monitoring technology

The fourth generation purifier of Guanglan is equipped with an IoT module, which can remotely monitor the operation status of the equipment. When the oil accumulation in the electric field exceeds the threshold, the system automatically sends a cleaning reminder to avoid the decrease in purification efficiency caused by untimely maintenance. After being applied in a hotel project in Beijing, the equipment failure rate decreased by 76%.

3. Minimalist maintenance design

Adopting a modular electric field structure, the electrode plates can be removed by simply removing the front cover plate during cleaning. Guanglan's unique self-cleaning coating technology forms an oil repellent film on the surface of the electrode plate, which can be restored to cleanliness by rinsing with clean water. The single maintenance time has been reduced from 2 hours to 20 minutes.

3、 Common Misconceptions in Installation and Use

Misconception 1: The greater the device power, the better

Excessive air volume can cause negative pressure in the kitchen, affecting the smoke exhaust effect. The correct approach is to match the air volume according to the number of stoves, for example, for every additional double burner, the air volume needs to increase by 2000m³ /h。

Misconception 2: Neglecting pipeline design

Excessive bends or sudden changes in pipe diameter can cause turbulence in airflow and increase system resistance. The Guanglan Engineering team uses CFD fluid simulation technology to optimize pipeline layout, reducing system pressure loss by 40%.

Misconception 3: Long term failure to clean equipment

Electric field oil accumulation exceeding 3mm can cause discharge sparks and pose a fire hazard. It is recommended to clean it every 2-3 months. Guanglan provides professional cleaning services and uses neutral cleaning agents to avoid corrosion of the electrode plates.

4、 How to evaluate the purification effect?

Three elements of on-site inspection:

• Processing air volume: It needs to be calculated based on the kitchen area and the number of stoves. It is recommended to configure it according to the standard of 60 air changes per hour.. For example, in a 30 square meter kitchen, an 8000m³ /H air volume equipment is more suitable.
• Purification level: Priority should be given to equipment that has passed environmental certification at level 2 or above. All products in the Guanglan purifier series have passed CQC environmental certification and comply with GB18483-2001 emission standards..
• Material and process: The stainless steel shell has stronger anti-corrosion performance, and the recommended thickness of the electric field electrode plate is 1.2mm to avoid deformation during long-term use.

In third-party testing, the Guanglan purifier achieved a particle removal rate of 98.7% and a non methane total hydrocarbon removal rate of 96.3%, far exceeding industry standards. After the installation of a certain Western restaurant, the number of complaints from surrounding residents has been reduced to zero, and the environmental protection department has achieved a 100% pass rate in random inspections.

When choosing oil fume purification equipment, it is important to consider both initial investment and long-term usage costs. Through technological innovation, the Guanglan purifier extends the service life of a single device to over 8 years, and with the rapid response provided by over 200 service outlets nationwide, truly achieves the goal of; One investment, long-term peace of mind;. When you see that the kitchen staff are no longer blinded by oil fumes, and when the environmental inspectors show a satisfied smile, you will understand that a professional and comprehensive plan is the cornerstone of sustainable development for catering enterprises.

• Visual emission: The exhaust outlet should have no visible oil mist, and the white paper should be close to the exhaust outlet for 30 seconds without oil stains.
• Odor detection: There should be no obvious oil fume odor at a distance of 5 meters from the exhaust outlet
• Data Monitoring: When using a particulate matter detector, the PM2.5 concentration must be below 1.0mg/m3.;
