Some restaurant kitchen appliances use solid fuel such as mesquite, charcoal and hardwood to cook and heat food. It adds another dimension to restaurant offerings - from pizzas to smoked meat - and also for a wider array of flavor and cooking capabilities. Although solid fuels can be highly combustible and increase the potential for safety risks, restaurant owners can safely use most solid fuel appliances with the right amount of understanding and preparation.
Nearly 60 percent of all restaurant fires start in the kitchen. Though usually small and resulting in limited damage, restaurant kitchens have all the ingredients for a destructive fire, and restaurants pose a unique risk because of the potential for large numbers of customers at one time.
Typically made from aluminum or stainless steel, baffle filters – often called hood filters – function by forcing grease-saturated air to quickly and repeatedly change direction as it rises through the filter. Because the grease droplets cannot change directions as rapidly as the air carrying them, they end up condensing and sticking to the metal blades and then draining into the filter tray. This also drastically reduces the risk of spreading flames should a fire break out on the cooking surface below.
