Embodiment Construction

[0013] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0014] figure 1 In the process, after the motor 2 is started, the power drives the stirring shaft 17 and the stirring blade 8 to rotate through the reducer 3, and the subdivided plant dry material enters the first layer of extractor from the feeder 1, closes it after reaching the specified amount, and turns on the microwave When the generator 6 irradiates and heats the dry material to the specified requirements, the solvent is pumped by the solvent pump P 1 Through the solvent inlet gate valve 10 and the filter screen cavity 9, reversely press the extractor from the bottom of the material layer to extract the material. After reaching the process requirements of the stage, the mixed liquid is in the vacuum pump P 2 Under the suction of the generated negative pressure, it is discharged through the discharge gate valve 11, and then the discharge ...

Abstract

The invention relates to a device for wetly extracting effective ingredients in a plant by using microwave. The device consists of an extraction component, a stirring component and a microwave radiation heating component. The device is characterized in that the extraction component consists of a plurality of circular barrels with filter screen cavities and baiting flat gate valves; the stirring component consists of a motor, a speed reducer, a stirring shaft, a sealing shaft sleeve and a plurality of layers of stirring paddles; and the microwave radiation heating component consists of a plurality of groups of microwave generators arranged on the top and the periphery of the barrels and a protective cover. The device directly radiates and heats a dry plant material by adopting microwave and then adopts an extraction method by adding a solvent so as to greatly save the energy consumption and the extraction time and improve the quality and yield of a subject matter; and the device can be widely applied to the industries of pharmacy, food and chemical engineering.

Description

technical field [0001] The invention relates to a device for extracting effective components in plants, in particular to a device for microwave dry extraction. Background technique [0002] A device that uses microwaves to extract active ingredients from related plants, that is, a microwave extraction device, currently has many forms, but most of them are wet extraction devices, that is, the subdivided plants or by-products are mixed with an extraction solvent and packed in a container. Commonly accept microwave irradiation heating extraction, this kind of device generally has disadvantages such as long extraction time, high energy consumption, many impurities in the product, difficult separation and purification, and inability to continue industrial production, so it is rarely put into production and application, and the cost is high. promote. Contents of the invention [0003] The object of the present invention is to provide an energy-saving, high-efficiency, and quick...
