Plant stem type continuous microwave expansion device

Abstract

The invention discloses a plant stem type continuous microwave expansion device and aims at providing the plant stem type continuous microwave expansion device which is capable of meeting the high-yield and continuous production requirement. The plant stem type continuous microwave expansion device comprises a rack, a swing arm and a microwave source cavity, wherein the middle of the swing arm is hinged and obliquely supported on the rack, the swing arm can swing and be adjusted around a hinge point, and the microwave source cavity is fixedly arranged on the swing arm. The plant stem type continuous microwave expansion device is characterized in that the microwave source cavity is internally provided with a material barrel fixedly connected with the microwave source cavity, a feeding port is formed in one end of the material barrel, and a discharging port and a dust removing connector are arranged at the other end of the material barrel; a rotating shaft is rotationally arranged in the material barrel, and the axial lead of the rotating shaft is identical with the axial lead of the material barrel; the rotating shaft is provided with a plurality of material lifting plates, and the rotating shaft is connected with a drive motor. The plant stem type continuous microwave expansion device is simple in structure, low in manufacturing cost, convenient to maintain and capable of effectively reducing the operation cost of a user.

Description

technical field [0001] The invention relates to the technical field of microwave drying equipment, in particular to a continuous microwave expansion device for plant stems. Background technique [0002] With the rapid development of modern tobacco, food, and pharmaceutical industries, the processing technology of plant stems is also constantly developing. Using microwaves to dry and expand plant stems can effectively reduce the bitterness, spicy taste and woody smell of plants. The inside of the plant stem is porous, easy to absorb other additives, and can be used as a good compatible raw material. [0003] At present, there are not many related patents for this type of equipment. The authorized notification number is CN2607033Y utility model patent: multi-wave source and multi-feeder microwave expansion tobacco stem device, which proposes a microwave radiation cavity on the basis of mesh belt feeding equipment, and uses microwave radiation to control the tobacco running on...

AI Technical Summary

Problems solved by technology

Both methods have the problems of uneven microwave radiation, easy damage to the mesh belt, and difficulty in controlling microwave leakage

The invention patent application with the application publication number CN102326858A: a drum-type tobacco stem continuous microwave expansion device, which proposes a device for adding microwave radiation bins outside a rotating drum. The tobacco stems will move continuously and receive microwave radiation in the drum, thereby solving the problem of microwave radiation uniformity, but this method also has difficulties in manufacturing the rotatable large-diameter and long-length drum, and it is difficult to increase the output of the equipment. Relatively difficult problems of sealing and microwave leakage control
