The working principle of the invention is as follows: the airflow is reversed through the air guide groove 214, the consumption efficiency of the oxygen-containing airflow is improved, the oxygen-containing airflow is subjected to internal circulation in the combustion channel, the air guide groove 214 is reversed in an arc shape, the air guide smoothness is improved, the flame is contracted through the flame pressing surface 212, the flame combustion radius at the lower end of the flame pressing surface 212 is reduced through the arc shape, the flame combustion radiation distance is further improved, the flame combustion intensity is limited through the flame pressing surface, the phenomenon that the too-large flame directly burns the material to be roasted excessively to affect the edible safety is avoided, the material to be roasted is roasted through the flame channels on the two sides, and the roasting efficiency and the roasting uniformity are improved; through the arrangement of the baking cavity 11 and the combustion chamber 12 respectively, two baking areas with different heat quantities are provided, so that the baking with big fire and the baking with small fire can be distinguished conveniently, the practicability is improved, through the gradient arrangement, the baking can be effectively prevented from being burnt or the baking is not done due to low local temperature, and the heat quantity is utilized to the maximum; the flame radiation distance is increased through the flame leaping channel 13, so that the flame extends into the combustion chamber 12 through the flame leaping channel 13, carbon monoxide is ignited, the carbon monoxide is re-combusted, the phenomenon that the carbon monoxide is directly discharged and the air is polluted is avoided, and particularly in places without wind or with poor air flow, poisoning caused by overhigh concentration of the carbon monoxide around operators is avoided through the carbon monoxide re-combustion; when the fuel burning is totally done up, sharply reduce the oxygen consumption, the universal driving shaft 42 is to power rotary oar 41 and the linkage of the rotary oar 43 of airing exhaust, make advance, exhaust quantitative transfer, so when oxygen consumption is little, the quantity of gas that carbon dioxide adsorbent absorbs reduces promptly, thereby make the air exhaust increase in the rotary oar 43 unit interval of airing exhaust, pressurize the back through jet groove 224, the velocity of flow increases, the suction that produces through negative pressure runner 226 upside increases, thereby make the inside atmospheric pressure of feed bin 221 further reduce, thereby commentaries on classics board 23 overcomes pretension spring elasticity and rotates and makes the fuel after preheating from getting into combustion channel in the feed bin, carry out the automatic feed supplement, improve the baking stability.
