At present, the latest environmental protection and energy-saving barbecue buffet equipment on the market is far-infrared barbecue oven, which does not need to install smoke exhaust facilities and is smoke-free and environmentally friendly. Wuhan Xindatian does smokeless barbecue in this respect, so you can learn more about it. Far infrared rays are harmless to human body, accounting for 72% of sunlight. Because the vibration frequency of far infrared rays is close to the vibration frequency of cells and molecules in human body, the "life light wave" will cause the atoms and molecules of human cells to vibrate after penetrating human body. Through the absorption of * * *, the friction between molecules will generate heat, form a thermal reaction, promote the temperature rise in the deep subcutaneous layer, dilate capillaries and accelerate blood circulation, which is beneficial to removing blood vessel deposits and is beneficial to the body. Therefore, far infrared rays can improve and prevent many diseases caused by blood circulation and microcirculation disorders.
