The invention belongs to the drying or sterilization processing machinofacture field in which solid or semi-liquid materials and the like of food, traditional Chinese medicinal materials, chemical engineering products and agricultural and sideline products can keep vacuum degree under the conditions of material feeding and discharging. The continuous microwave vacuum drying processing device is mainly formed by the combination of a feeding conveyer belt, a feeding / discharging sealing device, a vacuum chamber, a material bucket, a material fixing pump, a material distributing device, a heater, a microwave magnetic control device, a fetching device, a microwave choke device, a conveyer belt, a vacuum system, a feeding / discharging fixed supply device, a material conveyer belt and a storage tank. The equipment not only lowers drying temperature, but also quickens drying speed, has the characteristics of rapidness, high efficiency, low temperature and the like, can better retain original color, aroma and taste of processed materials of food, medicine and the like, the loss of vitamin and other thermal sensitive nutrition or active ingredients, thus obtaining better drying quality, ensuring the processed products to reach the requirement of high quality, high benefit, high energy conservation and time saving, being favorable for environmental protection and social comprehensive benefit, and having wide variety applicability.
