DEVICE FOR THE HEAT TREATMENT OF A PRODUCT |
| 摘要 |
The invention relates to a device for the heat treatment of a product, comprising an enclosure, means for transporting the product between an inlet of the enclosure and an outlet of the enclosure, which comprise a screw mounted in such a way as to rotate in the enclosure according to a geometric rotational axis and means for rotatably driving the screw, and means for heating the screw by Joule effect. According to the invention, the screw has an electrical resistance that varies along the geometric rotational axis. |
