Shawarma Vertical Broiler Product

Overview

A shawarma broiler is a vertical rotating-spit meat-cooking appliance used in Middle Eastern, Turkish, and Levantine cuisine. Marinated meat (lamb, chicken, or beef) is layered onto a vertical rotating spit cone, then exposed to intense radiant heat from burners positioned in front and on both sides. As the spit rotates, outer meat layers cook and brown; the operator uses a long knife to shave off cooked meat continuously throughout the service period. A single meat cone typically yields 60–100 lbs of cooked product over 30–45 minutes of cooking.

The broiler combines a motorized spit drive (rotating the cone at 5–15 RPM), a multi-burner heating array (total 100,000–150,000 BTU/h), a grease catch tray, and a protective carving access system. The cooking temperature reaches 500–700°F at the meat surface via infrared or flame burners. The rotating motion ensures even cooking and prevents hot-spotting, while the radiant heat develops the characteristic brown crust (the "shawarma char") expected in traditional preparation.

How it works

The Spit Drive Motor Assembly, powered by a 1–2 hp AC AC Motor, spins the vertical Spit Shaft at a fixed speed (5–15 RPM, adjustable via pulley ratio). The motor drives a Gear Reducer (20:1), which steps down the 1,725 RPM motor speed. Power is transmitted via Drive Belt and pulleys to the spit shaft. A Motor Coupling accommodates eccentric loading as the meat cone rotates.

The Spit Shaft, a 1 inch stainless steel rod, carries the Meat Cone Frame — a cone-shaped stainless assembly holding stacked marinated meat layers separated by Layer Spacers. A Carving Blade is mounted on the lower spit axis to scrape the meat surface.

Heat is supplied by three burner arrays. The Front Burner Array (facing the meat cone) provides 50,000–80,000 BTU/h of infrared or flame heat. Two Side Burners on left and right each deliver 20,000–30,000 BTU/h. All burners are controlled by a Burner Control Valve (manual hand valve with optional thermostat). Gas flows through the Gas Manifold to each burner array. An Ignition and Safety with thermocouple provides continuous pilot ignition and safety shutoff.

Meat drippings and rendered fat fall from the rotating cone into the Grease Catch Tray Assembly, which includes a sloped Catch Tray, Drain Tube, and Grease Filter to prevent clogging. Grease drains into an external waste container.

The Protective Shield is a hinged stainless panel that protects the operator from spit rotation and radiant heat. When carving, the operator opens the shield and uses a long carving knife guided along the Knife Guide Rail to shave thin slices of hot meat continuously. The Frame and Enclosure provides structural support and thermal insulation via Panel Insulation.

Temperature is monitored via a Dial Thermometer mounted on the cabinet. An optional Electronic Thermostat can automate burner control to maintain steady cooking temperature.

Cooking and carving

The outer surface of the marinated meat cone reaches 160–180°F internal temperature while the exterior browns and crisps to 400–500°F. As the spit rotates continuously, different zones of the meat are exposed to the burner heat in sequence, ensuring uniform cooking. Typical batch cycles require 30–45 minutes to cook a full 80–100 lb meat load, during which the operator shaves off approximately 10–15 lbs per hour of cooked product onto a waiting sandwich bread or plate.

Meat shaving is a skilled task: the operator uses a long serrated carving knife held at a shallow angle, slicing thin (0.125–0.25 inch) strips from the rotating, hot meat surface. The knife must be guided precisely to avoid contact with the spit or cone frame. A dull blade or poor angle can tear meat fibers instead of cleanly slicing, reducing yield and appearance quality. Professional shawarma chefs often sharpen their knives multiple times per shift.

The spit rotation speed affects carving ease and meat browning: slower speeds (5–8 RPM) allow deeper cooking and more uniform browning but extend batch time; faster speeds (10–15 RPM) accelerate cooking but risk undercooked interiors if the spit is loaded heavily.

Maintenance

The vertical Spit Shaft is subject to continuous eccentric loading and rotation; ball bearings at top and bottom require periodic lubrication and inspection every 500 hours of operation. The Drive Belt and pulleys must be checked for wear and tension monthly; slippage causes slower spit speeds and uneven cooking. Burner ports can accumulate carbon and grease; annual disassembly and cleaning of the Front Burner Array and side burners is recommended to maintain heat distribution. The Catch Tray and Grease Filter must be emptied daily to prevent overflow and ensure draining of rendered fat.

The Meat Cone Frame and Layer Spacers can warp if subjected to uneven loading or quenching (rapid cooling after shutdown); they should be inspected for straightness quarterly and replaced if bent beyond 0.5 inches eccentricity over a 20-inch span.
