Problems solved by technology

[0002] Among the existing drying processing equipment for solid or semi-liquid materials such as food, Chinese medicinal materials, chemicals, and 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 chemic

Embodiment Construction

[0041] Further describe structure and working process of the present invention below in conjunction with accompanying drawing:

[0042] Such as figure 1 As shown: a high-efficiency continuous vacuum microwave dryer for processing solid materials in the present invention, its working process: the materials for processing solid materials are sent to the drum-type sealing device (20) by the feeding conveyor belt (26) to be processed, The material is evenly distributed on the material conveyor belt (2) in the vacuum chamber (1) by the uniform material device, and the heating plate (3) is installed between the upper and lower belts of the material conveyor belt (2) to dry the part. After the material is conveyed to the terminal by the first layer of material conveyor belt (2), it will fall onto the second layer of material conveyor belt (2), and can be dried under the heating action of the first and second layer of heating plates (3). ≤85% most of the moisture, when the moisture i...

Abstract

The invention discloses an efficient continuous vacuum microwave drying machine and belongs to the field of drying processing machines which can keep the vacuum degree under the condition of continuous feeding and discharging of materials in a solid state or a semi-liquid state or other states of food products, Chinese herbal machine products, chemical products and agricultural and sideline products. The efficient continuous vacuum microwave drying machine is mainly provided with a feeding conveying belt, a rotary drum type feeding/discharging sealing device, a vacuum chamber, a heating device, a microwave magnetic-control device, a material conveying belt, a material turning device, a vacuum recovering system and a cleaning device. According to the drying machine, by the adoption of a steam and microwave combined heating drying way, energy and time can be saved by over 20%-30% compared with a single microwave heating drying way or a single steam heating drying way; the material turning device and the cleaning device for processing solid materials and semi-liquid materials are arranged, a condensation recovering device is added into the vacuum system, in this way, fragrant gas can be collected and converted into liquid, beneficial gas, poisonous and harmful gas, inert gas, gas prone to oxidation, combustible and explosive gas and the like can be recycled, high quality and high benefits of processed products can be achieved, environment protection is facilitated, and social comprehensive benefits are also facilitated.

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.
