grease extractor

Types of grease extractors

A grease extractor is a ventilation system that helps control and remove cooking odors, smoke, and grease from kitchen facilities. It is mainly used in commercial kitchens, such as restaurants and hotels. The following are some of the commonly used grease extractors.

• Fan filter units (FFU)

  Fan filter units (FFUs) are standalone grease extractors that combine a fan and a filter into one unit. They are usually placed on top of cabinets or equipment and work by drawing air through the filter to trap grease particles. FFUs are common in small kitchens where space is limited.

• Electrostatic precipitators (ESPs)

  Electrostatic precipitators (ESPs) use electrostatic charges to remove grease from the air. When the exhaust air passes through the ionizers, it produces negative ions that attach themselves to grease droplets, making them heavy enough to fall into the grease collection trays. These units are efficient and can remove small particles.

• Activated carbon filters

  Activated carbon filters are effective in eliminating odors but do not reduce grease. They work through the activated carbon adsorbing odor molecules from the air. These filters are usually used as a pre-filter before other grease removal devices or in situations where only odor control is needed.

• Grease duct systems

  Grease duct systems are large, heavy-duty ducts designed to carry greasy exhaust air out of the building. They should be made from materials that can withstand high temperatures and corrosion, such as stainless steel. These ducts often have vertical runs and horizontal branches leading to the kitchen hood.

• Grease trap hoods

  Grease trap hoods combine a kitchen hood and a grease trap. They are designed to capture and collect grease before it enters the duct system. Grease trap hoods usually have special baffle filters or cartridges that can remove large amounts of cooking grease.

• Ultrasonic cleaning systems

  Ultrasonic cleaning systems utilize ultrasonic waves to clean grease filters or kitchen hoods. These waves create millions of tiny bubbles in the cleaning solution, which implode and produce a powerful cleansing action that removes grease from the surfaces. Ultrasonic cleaners are efficient and can clean complex-shaped items.

Design of grease extractors

• Ceiling-mounted grease extractors:

  These grease extractors are mounted on the ceiling. They are usually found in kitchens with high ceilings or large buildings.

  Designs are sleek and modern. Often, they have stainless-steel finishes that make them look professional and clean.

  Ceiling-mounted grease extractors are designed to be out of the way, so they do not interfere with cooking or dining. They also have large filters to catch all the grease.

• Wall-mounted grease extractors:

  These are attached to the wall and are suitable for kitchens with limited space or smaller buildings.

  Wall-mounted grease extractors tend to take up less space. They have compact designs but are still powerful enough to remove grease.

  Many wall-mounted models have decorative finishes that can match or contrast with kitchen decor.

• Canopy grease extractors:

  Canopy grease extractors are hoods over cooking appliances. They are commonly used in commercial kitchens and some residential settings.

  These extractors are designed to hang over cooking surfaces. They have large, flat, and sloped panels that efficiently capture smoke and grease.

  Canopy models are tough and durable. They can handle heavy cooking loads and are often made from stainless steel or other strong materials.

• Ductless recirculating grease extractors:

  Ductless models are also known as recirculating models. They are suitable for places where ductwork is difficult to install.

  Ductless extractor designs are compact and can be easily installed over or integrated into cooking appliances.

  These extractors have advanced filtration systems. They usually include charcoal filters to remove odors and grease before recirculating the air back into the kitchen.

• Grease filter units:

  Grease filter units are simple and small. They are usually used in home kitchens and smaller commercial setups.

  These units consist of metal mesh or baffle filters that trap grease particles. They are installed in kitchen hoods or ducts.

  Grease filter units are easy to clean and maintain. They are typically removable and dishwasher-safe.

Scenarios of grease extractor

• Remove odours:

  Grease extractors remove the greasy build-up in the kitchen. This grease can be the source of bad smells in the kitchen. The grease will mix with the food odours and produce an unpleasant smell. When the grease extractor fan runs, it will remove the grease and the bad smells, and fresh air will replace them.

• Control temperature:

  The grease extractor also helps to control the temperature in the kitchen. When cooking, the cooking appliances generate a lot of heat. If this heat is not removed, it will increase the temperature of the kitchen and make the workers uncomfortable. The grease in the extractor will absorb some of this heat. The grease will then be replaced with cool air brought in by the ventilation system.

• Prevent equipment damage:

  If the grease extractor is not installed, the grease will stick to the surfaces of the cooking appliances. Over time, this grease can cause the appliances to malfunction. The extractor also keeps the cooking area clean and free of grease. With the help of the extractor, the surfaces in the kitchen will be clean and free of the grease that can damage appliances.

• Improve air quality:

  The main function of the grease extractor is to remove the grease and the cooking fumes from the kitchen. If the extractor is not installed, these pollutants will remain in the kitchen and contaminate the air. The air will circulate in the kitchen, and the workers will inhale it. The grease extractor will remove the grease and fumes; it will also remove the warm air. It will be replaced with fresh, clean, cool air from the outside. This air will be more pleasant to breathe.

• Increase comfort:

  The extractor increases the comfort level in the kitchen. With the extractor, the air in the kitchen will be cool and clean. The cooking conditions in the kitchen will be comfortable. With an extractor, the grease and cooking odours will be removed. If the extractor is not there, the kitchen will be hot and full of unpleasant smells. The extractor will also remove excess heat. The Grease Extractor will improve the working conditions in the kitchen.

How to choose a grease extractor

For business buyers, choosing the right grease extractor involves understanding the needs of their business and the specific requirements of their commercial kitchen. Here are some key points to consider:

• Understanding Kitchen Needs:

  Business buyers should assess the size and layout of their commercial kitchens. They need to determine how much grease is generated during cooking based on the type of food served and the volume of customers. This will help them understand the capacity and performance requirements for the grease extractors.

• Compliance with Regulations:

  Business buyers must research local health and safety regulations regarding grease extraction systems for commercial kitchens. They should ensure that the products comply with these regulations to avoid any legal issues or penalties.

• Quality and Durability:

  Business buyers should look for grease extractors that have high-quality materials and sturdy construction. They should choose products that are designed to withstand heavy use in a commercial kitchen environment and have a longer lifespan. They can also consider seeking products that offer warranties as a guarantee of quality.

• Ease of Cleaning and Maintenance:

  Business buyers should consider the cleaning and maintenance aspects of the grease extractor. They should choose products that are easy to disassemble and clean, with accessible filter and grease trap locations. This will ensure the proper functioning and longevity of the grease extractor, reducing downtime and maintenance costs.

• Energy Efficiency:

  Business buyers should consider the energy efficiency of the grease extractor. They can choose products that use energy-efficient motors or technologies, which will reduce energy consumption and operating costs. Additionally, energy-efficient products may also qualify for government incentives or rebates, providing potential cost savings.
