The heat source is comprised of heating elements which are installed on support arms, for position adjusting purpose, or they can be installed in a fixed position, or some of heating elements can be installed on support arms for adjustable position and some in a fixed position.
Every heating element is controlled separately, so they can deliver same or different temperatures.
Temperature of heating elements is set manually or by the microcontoller if we use certain grilling program.
In order to get an even meat grilling, better temperature transfer from heating elements to meat , pressure barbecue grill uses a speed reducer witch delivers different revolutions per minute to grill racks. Meat is moved around by rotating grill racks during grilling process , which assures the temperature is even distributed inside pressure barbecue grill, and meat is grilled evenly .
The grill racks are designed to meet the requirements of grilling of most used meat categories : steaks and ribs, turkey, chicken, thick roasts and thin roasts or other meat cuts or food.
The grill racks expose meat to temperature in the most possible efficient way , to get the desired grilled meat. The revolutions per minute of grill racks are set manually or by the microcontoller if we use certain grilling programs.
In order to keep all natural juices of the grilled meat, and to prevent them from evaporating , at the end of grilling period , the heat is turned off , and the grilled meat is allowed to cool down in presence of air pressure . When the grilled meat is cooled down, the air pressure is drained out of pressure barbecue grill , pressure barbecue grill is opened and the grilled meat can be used.
At the end of grilling period , for a faster cooling down of grilled meat , the rotation speed of grill racks is increased and a pressure barbecue grill cooling system , with water or forced air flow is used.
Grilling process is an important energy consumer. To prevent waste of energy through the pressure barbecue grill walls , an insulated cover is used during grilling period, this way , energy is saved and the grilling process is faster.
The pressure barbecue grill is used in vertical position, but for certain meats or certain grilling it could be used on horizontal position .
To prevent air leaking along drive shaft , which transfer rotation from speed reducer to grill rack rod, bushing and seals are used .
