Continuous microwave vacuum drying and sterilizing processing device

Abstract

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.

Description

technical field [0001] The invention belongs to the field of dry processing machinery manufacturing which can maintain the vacuum degree under the condition of continuous feeding and discharging of solid or semi-liquid materials such as food, Chinese medicinal materials, chemical industry and agricultural by-products. Background technique [0002] Among the existing drying processing equipment for solid or semi-liquid materials such as food, Chinese medicinal materials, chemicals, agricultural and sideline products, the ones with large output adopt normal pressure mesh belt type electric heating and steam drying processing, and the ones with small output adopt intermittent electric heating and steam drying. Vacuum drying cabinet, because the current large-scale solid materials are dried in continuous vacuum at low temperature and there is no equipment to solve the drying problem. The drying processing of some food, medicinal materials, chemical products, agricultural and side...

Problems solved by technology

[0002] Among the existing drying processing equipment for solid or semi-liquid materials such as food, Chinese medicinal materials, chemicals, agricultural and sideline products, the ones with large output adopt normal pressure mesh belt type electric heating and steam drying processing, and the ones with small output adopt intermittent electric heating and steam drying. Vacuum drying cabinet, because the current large-scale solid materials are dried in continuous vacuum at low temperature and there is no equipment to solve the drying problem. The drying processing of some food, medicinal materials, chemical products, agricultural and sideline products and other materials needs to be carried out at low temperature to keep food and medicine Drying of chemical products under low temperature conditions can avoid explosion and toxic and harmful gas spillage, but the existing equipment does not meet the above conditions, especially Chinese and Western medicine extracts, Chinese herbal medicines, tea, volatile materials and other materials need to be dried at low temperature Only by drying under certain conditions can the beneficial ingredients be maintained or improved, but since there is no solid or semi-liquid continuous microwave vacuum drying equipment for such materials and the moisture content cannot be sampled during the continuous vacuum drying equipment processing, we can only rely on the current existing equipment Processing, so inconsistent product moisture content affects product quality
