How can commercial kitchen electrostatic filters balance filtration efficiency and long-term stable operation?

In the catering industry, the "filtration effect" and "operation stability" of commercial kitchen electrostatic filters are the two core issues that merchants are most concerned about. Failure to meet the filtration standards may face environmental protection penalties, and frequent failures will increase operating costs. In fact, through scientific equipment selection, reasonable system adaptation and standardized maintenance processes, these two major needs can be effectively balanced. The following shares 3 proven and effective solutions.

1. Choose the right filtering technology to ensure efficiency from the source

The characteristics of oil smoke in different types of catering vary greatly, and blindly selecting equipment can easily lead to unstable filtering effects. For example, the oil smoke generated by Chinese stir-frying is high in concentration and large in particles, while the oil smoke generated by Western frying is lighter and thinner. If a filter filter suitable for light oil smoke is selected for a Chinese kitchen, the exhaust port may "smoke" after one month of operation, and the filtration efficiency will drop sharply from more than 90% at the beginning to 60%.

Targeted solution: Select technology according to the type of oil smoke.

Heavy oil smoke scene (Chinese food, barbecue): double pass electrostatic commercial kitchen electrostatic filter is preferred, which captures large particles of grease through ionization, has high filtration efficiency, can remove more than 98% of oil smoke, and achieve invisible smoke.

Light oil smoke scene (Western food, simple meals): single pass electrostatic commercial kitchen electrostatic filter can be selected, taking into account both filtration efficiency and cost.

In actual selection, it is necessary to make a comprehensive judgment based on factors such as the number of kitchen stoves and cooking frequency to ensure that the equipment matches the characteristics of oil smoke and avoid fluctuations in filtration efficiency from the source.

2.Do a good job of system adaptation to avoid "overload" operation of equipment

The electrostatic filter in a commercial kitchen is not an independent device. Its operating stability is closely related to the adaptability of the overall ventilation system of the kitchen. If the air volume of the filter does not match the air volume of the fan, it may cause the problem of "a small horse pulling a big cart" or "a big horse pulling a small cart": if the air volume of the fan is too large, the oil smoke will stay in the filter for too short a time and the filtration will not be thorough; if the air volume of the fan is too small, it will cause the oil smoke to accumulate and the filter load will be too high, which may easily cause component damage.

System Adaptation Points:

Air Volume Matching: The rated air volume of the filter must be consistent with the air volume of the fan, with a deviation of no more than 10%. For example, when the air volume of the fan is 10000m³/h, the filter needs to use a model of 9000-11000m³/h.

Air Pressure Coordination: Calculate the required air pressure based on the length of the pipeline and the number of elbows to ensure that the fan air pressure matches the filter resistance to avoid poor oil smoke discharge due to insufficient air pressure.

Linkage control: Link the start and stop of the filter and the fan to avoid oil smoke retention or equipment idling caused by separate operation.

Professional solution design will make an overall measurement of the kitchen ventilation system to ensure that the filter, fan, pipeline and other equipment form an efficient and coordinated system, reducing operational failures caused by improper adaptation.

3. Scientific maintenance process to extend the efficient operation cycle

Ignoring maintenance will lead to a rapid decrease in filtration efficiency and may also cause safety hazards. If the filter is not cleaned for a long time, the accumulation of internal grease may cause abnormal noise from the fan, a significant decrease in filtration efficiency, and a fire risk.

Standardized maintenance recommendations:

Daily cleaning: Wipe the surface of the equipment every week and clean the filter every month (you can soak it in a special degreasing agent for 30 minutes).

Deep maintenance: Disassemble and clean the electrostatic field every 3-6 months according to the oil smoke situation, and check the line connection.

Adhering to the scientific maintenance process can effectively extend the efficient operation cycle of the equipment, reduce the failure rate and maintenance cost, and ensure the long-term stability of the filtration effect.
