• Truck Dimensions: The size and layout of the food truck’s interior affect air circulation. Larger trucks or those with complex layouts may require higher CFM ratings to ensure adequate air movement and capture efficiency.
• Hood Design: The type of hood (e.g., wall-mounted, island, or pass-through) and its design characteristics (e.g., baffle configuration, grease filter type) can influence its effectiveness and the required CFM.
• Proximity to Walls and Other Equipment: The location of the hood relative to walls and other equipment affects airflow patterns. Obstructions can hinder the hood’s ability to capture contaminants.

Formula for Calculating Required CFM

The required CFM for a vent hood can be calculated using a formula that considers the type and quantity of cooking equipment. This calculation provides a starting point for determining the appropriate hood size. Local codes and regulations may specify additional requirements.

CFM = (Equipment Factor x Equipment Width) + (Additional Factor for High-Heat Appliances) + (Make-up Air Factor)

• Equipment Factor: This factor varies depending on the type of cooking equipment. It represents the estimated CFM per linear foot of the equipment. For example:
  • Fryers: 400 CFM per linear foot
  • Charbroilers: 600 CFM per linear foot
  • Ranges: 400 CFM per linear foot
• Equipment Width: This is the total width (in feet) of all cooking equipment under the hood.
• Additional Factor for High-Heat Appliances: For equipment that produces significant heat and smoke (e.g., charbroilers, fryers), an additional CFM factor is often added. This may vary based on local codes.
• Make-up Air Factor: This factor accounts for the amount of air that needs to be supplied to the food truck to replace the air exhausted by the hood. It is typically calculated as a percentage of the exhaust CFM.

Importance of Make-Up Air

Make-up air is the air that is supplied to the food truck to replace the air that is exhausted by the vent hood. Without sufficient make-up air, the vent hood will not function efficiently. This is because the negative pressure created by the hood will draw air from any available source, potentially including doors, windows, and other openings, which can disrupt airflow patterns and reduce the hood’s effectiveness.

• Maintaining Air Balance: Make-up air helps maintain a balanced air pressure within the food truck, preventing the build-up of negative pressure.
• Preventing Drafts: Proper make-up air prevents drafts that can interfere with cooking processes and create uncomfortable working conditions.
• Ensuring Efficient Hood Operation: Adequate make-up air ensures the vent hood operates at its designed capacity, effectively removing smoke, grease, and odors.
• Complying with Regulations: Many local health and safety codes require the installation of a make-up air system in conjunction with vent hoods to ensure a safe and healthy work environment.

Determining Hood Size with Cooking Equipment Examples

To illustrate how to determine the correct hood size, let’s consider two hypothetical food truck scenarios. The CFM calculations below are examples and may need to be adjusted based on local codes and specific equipment models.

1. Example 1: Burger Food Truck

   This food truck has a 4-foot flat-top griddle, a 2-foot charbroiler, and a 2-foot fryer. The truck is 8 feet wide and 16 feet long.

   CFM Calculation:

   • Griddle: 4 feet x 400 CFM/foot = 1600 CFM
   • Charbroiler: 2 feet x 600 CFM/foot = 1200 CFM
   • Fryer: 2 feet x 400 CFM/foot = 800 CFM
   • Total Equipment CFM: 1600 + 1200 + 800 = 3600 CFM
   • Considering the high heat of the charbroiler, an additional 200 CFM is added (this is a simplified example; the actual amount may vary).
   • Total CFM: 3600 + 200 = 3800 CFM
   • Make-up Air: Assuming a 75% make-up air requirement, 3800 CFM x 0.75 = 2850 CFM.

   Hood Size Recommendation: Based on this calculation, a hood with a minimum rating of 3800 CFM, and a make-up air system providing at least 2850 CFM, would be recommended. The hood would need to be sized to cover the entire cooking line. A hood that extends at least 6 inches beyond the cooking equipment on all sides is a good practice to capture all the fumes.

   Imagine the food truck’s interior. The cooking line, consisting of the griddle, charbroiler, and fryer, is positioned along one wall. The hood is positioned above the cooking line, extending beyond each piece of equipment, visually capturing the rising smoke and grease. The make-up air system is integrated into the hood or a separate unit, introducing fresh air to maintain the balance within the truck.

2. Example 2: Taco Food Truck

   This food truck features a 6-foot range with multiple burners, a 3-foot steam table, and a 2-foot flat-top griddle. The truck is 7 feet wide and 18 feet long.

   CFM Calculation:

   • Range: 6 feet x 400 CFM/foot = 2400 CFM
   • Steam Table: 3 feet x 0 CFM/foot = 0 CFM (steam tables typically generate minimal smoke and grease)
   • Griddle: 2 feet x 400 CFM/foot = 800 CFM
   • Total Equipment CFM: 2400 + 0 + 800 = 3200 CFM
   • Add 100 CFM for the potential of higher usage on the range.
   • Total CFM: 3200 + 100 = 3300 CFM
   • Make-up Air: Assuming a 60% make-up air requirement, 3300 CFM x 0.60 = 1980 CFM.

   Hood Size Recommendation: A hood with a minimum rating of 3300 CFM, and a make-up air system providing at least 1980 CFM, is recommended. The hood should extend beyond the cooking line, capturing all cooking emissions. The make-up air system, perhaps located on the roof, would introduce fresh air into the truck to compensate for the air being exhausted by the hood.

   Picture the taco truck. The cooking line, consisting of the range and griddle, is under the hood. The steam table is located next to the cooking line. The hood efficiently captures the cooking fumes, with the make-up air system ensuring proper air balance. The hood is positioned above the cooking line, extending beyond each piece of equipment, visually capturing the rising smoke and grease.

• Baffle Filters: These are the most common type of grease filter. They are designed with angled baffles that redirect the airflow, causing grease-laden vapors to condense and drip into a collection trough. Baffle filters are generally effective at capturing large grease particles. Their efficiency is often rated based on their ability to remove grease particles of a specific size. Regular cleaning is crucial for baffle filters to maintain their effectiveness.

• Mesh Filters: Mesh filters are typically constructed from layers of fine metal mesh. They are less effective than baffle filters at capturing grease but are often used as a pre-filter or in conjunction with baffle filters. Mesh filters are prone to clogging and require frequent cleaning.
• Hybrid Filters: Some vent hood systems incorporate hybrid filters that combine the features of both baffle and mesh filters. These filters aim to maximize grease capture efficiency.

The effectiveness of grease filters is also influenced by factors such as airflow velocity and the type of cooking being performed. High-volume cooking operations and those involving high-grease content foods will necessitate more robust filtration systems and more frequent cleaning schedules.

Requirements for a Fire Suppression System in a Food Truck Vent Hood

Fire suppression systems are mandatory for food truck vent hoods in most jurisdictions. These systems are designed to automatically detect and extinguish fires that may originate within the hood or ductwork. The specific requirements for fire suppression systems are dictated by local fire codes and typically align with standards set by organizations such as the National Fire Protection Association (NFPA).

These codes Artikel the types of systems permitted, the coverage required, and the maintenance procedures. Compliance with these regulations is crucial for ensuring the safety of both the food truck and its occupants, and for obtaining the necessary permits to operate.

Components and Operation of a Fire Suppression System

A fire suppression system for a food truck vent hood is a complex assembly of components designed to detect and extinguish fires quickly and effectively. The system typically comprises the following elements:

Detection System: This system is responsible for identifying the presence of a fire. It often includes heat-sensitive detectors, such as fusible links or thermal detectors, that are positioned within the hood and ductwork. These detectors are designed to activate when they reach a specific temperature threshold, indicating a fire.

Suppression Agent: The fire suppression agent is the substance used to extinguish the fire. Common agents include wet chemical agents, which are designed to cool the fire, smother the flames, and prevent re-ignition. The type of agent used is chosen based on the types of cooking equipment present and the potential fuel sources.

Nozzles: Nozzles are strategically placed within the hood and ductwork to distribute the suppression agent. They are designed to deliver the agent in a targeted manner, ensuring that the fire is quickly extinguished. The number and placement of nozzles depend on the size and configuration of the hood and the potential fire hazards.

Control Unit: The control unit is the brain of the fire suppression system. It receives signals from the detection system and, upon detecting a fire, activates the release of the suppression agent. The control unit may also include features such as manual activation switches and system status indicators.

Actuation System: The actuation system is responsible for releasing the suppression agent. This system can be mechanical or electrical, and is triggered by the control unit. Mechanical systems often utilize a spring-loaded mechanism, while electrical systems rely on solenoids or other electrical devices.

Fuel Shut-Offs: These devices automatically shut off the fuel supply to cooking appliances when the fire suppression system is activated. This helps to prevent the fire from spreading and to ensure that the suppression agent is effective. Fuel shut-offs are a critical safety feature in any fire suppression system.

The operation of a fire suppression system is typically as follows:

1. A heat-sensitive detector (e.g., a fusible link) senses a fire and melts.
2. This triggers the release of the suppression agent from the storage tank.
3. The agent is discharged through nozzles, covering the cooking equipment and other potential fuel sources.
4. The agent cools the fire, smothers the flames, and prevents re-ignition.
5. Simultaneously, the fuel supply to the cooking appliances is automatically shut off.
