The invention relates to wood carbonization production equipment and a production process, in particular to an automatic production line for making charcoal from wood and a production process. The automatic production line comprises a plurality of wood trucks, a wood truck conveyor, a drying kiln, a tractor, a trailer, a transfer chamber, a truck pusher, a carbonization kiln, a cooling kiln, a charcoal discharge conveyor and a flue gas dust removal reclaiming device. Flue gas produced in the carbonization kiln is subjected to dust removal, separation and re-combustion through the flue gas dust removal reclaiming device; the produced hot gas is delivered to the drying kiln to dry the wood; and the wood is treated by five stages comprising drying, pre-carbonization, carbonization, burning and cooling to generate high-quality charcoal. The whole production line realizes mechanical operation, has high automation degree, good operating environment and high production efficiency, and greatly reduces the labor intensity of workers; the annual production of one production line is 1,000 to 10,000 tons; and the materials are loaded and unloaded at room temperature, no pollution is emitted, an external heat source is not needed during production, the energy is saved and the environment is produced, the wood is carbonized uniformly, and the quality of the manufactured charcoal is high.
