Abstract
The utility model provides an intermittent efficient vacuum microwave drying apparatus used for processing vacuum insulation board core materials, which comprises a microwave drying chamber. A carriage used for placing core materials to be dried is arranged in the drying chamber. A microwave generator also arranged in the microwave drying chamber emits microwaves to core materials placed on the carriage. One end of the microwave drying chamber is communicated with a vacuum pump and the other end of the microwave drying chamber is connected with an air processing device. During operation, core materials and water in the core materials are preheated through microwaves. Then water in the core materials is vaporized and generated steam is pumped out through vacuum-pumping. After the steam pumping process, hot dry air after being treated is pumped into the microwave drying chamber for replacing residual water in the microwave drying chamber. The above operation is repeatedly and intermittently operated for two to three times so as to completely dry the core materials. The intermittent efficient vacuum microwave drying apparatus integrating microwave drying with the vacuum drying gives full play to the drying advantages of the two drying modes and optimizes the drying process. Due to the adoption of the intermittent efficient vacuum microwave drying apparatus, the problem that the drying of insulation board core materials performed through the conventional direct heating method is high in cost, low in drying efficiency and poor in drying quality is solved.
