Charcoal will release carbon dioxide in the process of burning, which is colorless and tasteless. When it burns, there is no smoke in itself. Ordinary barbecue ovens have smoke when making products, because oil and spices fall into the carbon fire when making products.

Principle of gas barbecue oven;

Generally, stainless steel is used as furnace material. Through electronic pulse ignition, four independent high-temperature crystal red gas heating plates are heated by the combustion and heat of liquefied petroleum gas or natural gas, and then food is baked on the iron plate. With the control of energy-saving components, the electronic pulse switch can also control the flame to control the temperature of the iron plate, which is practical and convenient.

Principle of electric barbecue oven:

The heat source directly acts on the direct-fired electric barbecue oven of food. In the barbecue process, the food grease immediately drops, and there is no repeated penetration of oil, that is, there is no frying process of oil, so the food contains less oil, and the baked food is the real barbecue taste.

Grill selection:

1. Consider whether the barbecue oven is portable. Outdoor barbecue is our own thing, so it is best to consider this aspect when buying, which can be convenient for us to carry and bring us a lot of convenience. Folding barbecue is recommended here.

2, according to the material to buy. There are many kinds of barbecue grills in the market, and the prices are different. You don't need to buy expensive ones, but the service life of iron barbecue grills is definitely not very long. Therefore, it is recommended to choose stainless steel, which is more durable than iron and not easy to rust.

3, according to the size of the barbecue. Some people think that the smaller the portable one, the better, but the number of barbecues should also be taken into account. Therefore, when shopping, you can determine the size of the barbecue oven according to the number of barbecues each time, so that everyone can eat delicious barbecue.

4, whether with oil guide and smoke prevention device. When you barbecue, the meat will drip oil. Oil droplets will smoke on hot stones. When smoke comes into contact with food, it will have a bad taste. Therefore, the furnace should have some equipment to catch the oil and then let the oil flow out of the furnace.

Do you have a thermometer? In the barbecue menu, we often see at what temperature and how long. If there is no thermometer, we can only guess, so it is difficult to judge whether the food is cooked.
