ABSTRACT:
A magnetic vacuum oven mounted in a two piece steel magnet core. The two sections of the magnet slide apart on rails to provide easy access to the interior of the machine for maintenance and repair. The magnet core includes a "safe door" that is mounted on an articulated hinge or other hinge mechanism. The safe door provides direct access for product introduction to and removal from a central chamber surrounded by an applied magnetic field. Two electromagnet elements are mounted around the central chamber. One of the electromagnet elements is mounted in the front section of the housing, and one of the electromagnet elements is mounted in the rear section. The coils are separated by a small air gap to allow vacuum evacuation of the interior of the chamber. The magnetic coils are generally rectangular, and are water cooled to maintain a stable temperature when they are drawing power in operation.
