The invention discloses a low-temperature negative pressure
drying method and a low-temperature negative pressure
drying device for
textile materials and textiles. The device comprises a
microwave source, a temperature sensor, a
resonant cavity, an air-cooled or water-cooled device, a vacuum sensor, an air release valve, a
humidity sensor, an air extraction valve, an air extraction pipeline, a
vacuum pump, a
vacuum pump motor, a stirrer, a panel, a controller, a shielding sealing door, a shell, an indicating lamp, a switch, a scattered article
drying box and a cheese drying bracket; and the scattered
textile materials or textiles are put into the scattered article drying box, or cheeses are stacked on the cheese drying bracket and then put into the
resonant cavity, and the dried articles are heated and dried under the low-temperature negative pressure working condition. Relatively long
bottleneck at the uniform velocity drying stage when single
microwave is used for drying can be effectively overcome, over drying is avoided, and the whole drying process is quick and energy-saving; and the method and the device can particularly meet the drying requirements of special animal fibers, artificial fibers, synthetic fibers and like and the products thereof with special temperature requirements.
