Silicon material microwave heating system

The utility model provides a silicon material microwave heating system. The silicon material microwave heating system comprises a rack, and a heating buffer cavity, a microwave heating cavity, a wave suppression gate and a conveying roller way which are arranged on the rack, the heating buffer cavities are respectively arranged at the front and rear ends of the microwave heating cavity; the wave suppression gates are fixedly arranged at the front end and the rear end of the heating buffer cavity correspondingly. And the conveying roller way sequentially penetrates through the heating buffer cavity and the microwave heating cavity. Compared with the prior art, the system has the advantages that by reasonably arranging the heating buffer cavity, the microwave heating cavity and the wave suppression gate, continuous microwave heating of the silicon material can be completed, microwave leakage and silicon material oxidation are avoided, and the production efficiency is improved.
