Learn More About the Exhaust Hood and Fresh Air Supply System
The exhaust hood and fresh air supply system is considered an intelligent solution to create a clean and safe environment in industrial kitchens. This is a complex system comprising various crucial components such as the capture hood frame, smoke extraction ducts, exhaust fan, air filtration system, and fresh air supply system. Let’s explore the details of this system to gain a better understanding of its vital role in enhancing the quality and hygiene of every dish.
Structure of the Industrial Kitchen Exhaust Hood System
The industrial kitchen exhaust hood system is an essential solution for removing heat, smoke, and grease odors generated during the cooking process. It is commonly installed in the kitchens of restaurants, hotels, school cafeterias, hospitals, factories, companies, and various other locations. This system includes the following important components: the hood capture frame, ductwork system, and exhaust fan.
The restaurant kitchen exhaust hood system or industrial kitchen exhaust system plays a crucial role in maintaining a clean, comfortable, and safe working space. It helps eliminate smoke and heat that can cause discomfort, ensuring that the cooking area is always in the best condition to create delicious and aromatic dishes for customers.
Hood Capture Frame
The hood capture frame in restaurant kitchen exhaust systems is a critical part, often manufactured from stainless steel for durability and aesthetics. It is placed directly above the cooking area to effectively capture smoke, grease, and vapors released from food. The installation of this equipment needs to be designed based on the kitchen’s layout and should exhibit aesthetic appeal to blend with the space, creating a safe and visually pleasing working environment.
In the exhaust hood, a grease filter is used to capture grease and prevent it from being discharged into the external environment. This filter is usually removable, making the cleaning process more convenient. To maintain optimal performance, the exhaust hood needs to be cleaned regularly, especially after a day of heavy food preparation. In cases of lighter cooking, cleaning can be performed once a week.
Additionally, proper lighting arrangements are necessary within the exhaust hood to increase brightness at the cooking area. These lights are specially designed to withstand heat and the greasy environment, ensuring they function based on the suction power of the exhaust fan motor and illuminate the workspace enough for efficient and safe operation.
Smoke Duct in the Industrial Kitchen Exhaust Hood System
The smoke duct is a crucial component of the exhaust hood system, connecting the capture hood to the exhaust fan and ensuring that smoke is expelled from the kitchen space and released into the external environment. Typically, these ducts are made of stainless steel 430 or galvanized sheet metal to ensure durability and corrosion resistance. When designing the kitchen area, calculating and arranging the ductwork is vital to ensure an effective removal of smoke and hot air from the kitchen without causing noise disturbances and providing comfort for those working in the kitchen. Ducts can take various shapes such as square, rectangular, or round, depending on the kitchen’s requirements and design.
Smoke Extraction Fan
The smoke extraction fan in the exhaust hood system needs to generate strong suction force to effectively remove smoke and create high pressure, often reaching over 100,000 Pa. Therefore, centrifugal fans are generally preferred over axial fans in these applications. The choice of fan power (horsepower) should comply with the system’s requirements, including the length of the capture hood and smoke duct, to ensure that the system can operate efficiently and meet the smoke extraction needs in the kitchen space.
The investment cost in the exhaust fan system is a crucial aspect of the investment plan for the kitchen area. The kitchen’s ability to cook efficiently and with high quality depends significantly on the working environment, especially the air quality in the kitchen space. High temperatures, thick smoke, and loud noise are often the result of incorrect choices regarding the power and efficiency of the fan. This can create an unfavorable working environment for the kitchen staff and impact the quality of the food.
In the pursuit of culinary excellence, the kitchen environment plays a pivotal role. Saigon Horeca is dedicated to providing solutions and products that contribute to establishing the optimal working conditions for artistic chefs.
Why Should You Use an Industrial Kitchen Exhaust System?
The industrial kitchen exhaust system in a professional restaurant not only eliminates smoke but also captures the aromatic scents of dishes, creating a comfortable and delightful atmosphere.
Industrial kitchens, where large quantities of food are prepared, often produce a significant amount of smoke, odors, and emissions during cooking. The pungent smells from fish, meat, humidity, and even the odor of fuels like coal, gas, or alcohol can create an uncomfortable and stifling environment, diminishing the aesthetic appeal of the kitchen.
Especially for open-design eateries, managing odors and smoke becomes even more critical. Customers not only come to enjoy delicious meals but also observe the cooking process directly. Therefore, an effective kitchen exhaust system becomes a crucial solution, helping to establish a clean and hygienic working environment. Additionally, it enhances professionalism, reliability, and the overall presentation of food.
The Role of the Kitchen Exhaust System in Removing Smoke: Ensuring a Clean and Comfortable Kitchen Space
According to studies on cooking and health-related issues, smoke generated in European and Asian restaurant kitchens can contain harmful particles and chemical compounds that may impact health. Long-term exposure to these elements, particularly for staff and chefs, can lead to respiratory and pulmonary issues.
Understanding the potential impact of cooking smoke on health is crucial and should be considered seriously. Cooking smoke may contain dust particles and chemical compounds harmful to health, especially with regular and prolonged exposure. Staff and chefs may continue to expose themselves to these harmful factors in the workplace.
The potential impacts may include respiratory and pulmonary issues, as previously mentioned. This makes managing and improving air quality in the kitchen environment extremely important. An effective kitchen exhaust and ventilation system can help minimize the risk of exposure to harmful smoke and dust particles, thus protecting the health of restaurant staff.
Enhancing the Working Environment for Chefs with an Efficient Exhaust System
Information about the ideal temperature in the kitchen and the impact of temperature on chefs’ performance is crucial. A comfortable working environment with stable temperatures can help chefs concentrate and work more efficiently. This also contributes to improving the quality of the food, preserving the natural flavors of the ingredients without being affected by smoke or a humid environment.
With factors such as hygiene, food safety, and professionalism, the kitchen exhaust system becomes an integral part of restaurant kitchens. It not only improves working conditions for chefs but also ensures that food is prepared and served at its best quality.
Arranging an Industrial Kitchen Exhaust System
Installing an outdoor exhaust fan comes with various benefits, such as saving indoor space and ensuring the durability of the machine frame. When installing, ensuring the optimal height and minimum distance from the ground and outside the kitchen surface is crucial to guarantee the best smoke extraction performance.
Additionally, considering noise levels and aesthetics in the installation of the exhaust system is also essential. This helps maintain a comfortable kitchen space for chefs and staff, creating a professional and aesthetically pleasing environment for food preparation and service in the restaurant.
