Charcoal is the carbon dioxide released in the process of burning, it is colorless and odorless, and the charcoal is burned, and there is no smoke in itself. Common grills have smoke when making products because oil and seasonings are dropped on the charcoal fire when making products.
Principle of gas grill
Generally, stainless steel furnace body is used, which is ignited by electronic pulse, and uses the combustion and heat of petroleum liquefied gas or natural gas to heat the four independent high temperature resistant crystal red gas heating plates above, and then bake food on the iron plate. Looking at the energy-saving component control, the electronic pulse switch can also control the size of the flame, which is practical and convenient to control the temperature of the iron plate.
Principle of electric smokeless BBQ grill
A direct-fired electric barbecue with a heat source directly acting on the food, the food oil drips immediately during the barbecue, and there is no repeated infiltration of the oil, that is, there is no oily frying and frying process, so the food contains less oil and barbecue. The food that came out was a real BBQ taste.
Principle of microwave smokeless grill

Microwave ovens use microwaves to pass through insulating materials such as glass, ceramics, plastics, etc., but do not consume energy; and food containing moisture, microwaves are not only impermeable, but their energy will be absorbed. The shell of the microwave oven is made of metal materials such as stainless steel, which can prevent microwaves from escaping from the oven, so as not to affect people's health. Food containers are made of insulating material. The heart of a microwave oven is the magnetron. The tube, called a magnetron, is a microwave generator that produces microwaves that vibrate 2.45 billion times per second. This microwave invisible to the naked eye can penetrate food up to 5cm deep, and make the water molecules in the food move along with it. Vigorous movement generates a lot of heat energy, so the food is "cooked".
