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
The present invention relates to a kind of equipment that extracts effective components in plants, particularly a kind of device that is used for the dry microwave extraction.
Background technology
Utilize the device of microwave effective component extracting from relevant plant, it is microwave extracting apparatus, current have a various ways, but great majority are the liquid extraction device, promptly adopt will segmentation plant or byproduct mix with extractant to be contained in and accept microwave irradiation jointly in the container and add extraction heat, this type of device ubiquity extraction time is long, energy consumption is big, product impurity is many, separate purification difficult and can't continuous industry production etc. unfavorable factor, put into production and use lessly in the historical facts or anecdotes border, and cost height is difficult for promoting.
Summary of the invention
Purpose of the present invention, just be to provide a kind of energy-conservation, efficient, quick from plant the device of effective component extracting, can be widely used in pharmacy, food, the chemical industry.
For realizing purpose of the present invention, a kind of dry microwave extraction device provided by the invention is characterized in that earlier dry material being carried out irradiated heat, it is fully dewatered, add solvent again after expanded and extract.
This device comprises the extraction parts, mixing component, and the microwave irradiation heater block is formed.Be characterized in: described extraction parts are combined through connecting flange by a plurality of circular cylinder bodies that have filter screen cavity and the flat gate valve of blanking, described mixing component is made up of motor, decelerator, shaft, sealing axle sleeve and stirrer paddle, and described microwave irradiation heater block is made up of the many groups microwave generator and the protective cover that are installed in top and cylinder neighboring.
Above-mentioned microwave generator frequency is 2450 megahertzes or 915 megahertzes.
Compared with prior art, the invention has the beneficial effects as follows:
After the plant dry material of segmentation enters the ground floor extractor, stir in stirring and fully to accept microwave irradiation under the state, impel the moisture in the dry material to generate heat fast, vaporization, expansion is also burst cell membrane and is overflowed, the material grain has obtained expanded when dry material heats up dehydration, the normal temperature solvent that add this moment carries out desorb by enter into material intragranular portion because of the expanded micropore that forms to subject matter rapidly, therefore extraction time and solvent load have significantly been saved, improved subject matter quality and yield, thereby reached energy-conservation, efficiently, the purpose of quick extraction effective ingredients in plant.
Each layer re-extract the time, ground floor began charging, irradiation and the extraction operation of a new round again, thereby has reached the purpose of relative continuous extraction, is adapted to suitability for industrialized production below material after extraction first in time was discharged to.
Overall process is carried out under the state of sealing, and is few to some active constituent content, particularly useful to the plant subject matter extraction of light and air-sensitive.
Fig. 1 is an overall structure schematic diagram of the present invention
Among the figure: feeder 1, motor 2, decelerator 3, exhaust steam valve 4, protective cover 5, microwave generator 6, connecting flange 7, stirrer paddle 8, filter screen cavity 9, advance solvent gate valve 10, discharge opeing gate valve 11, sealing axle sleeve 12, exhaust hole 13, discharge gate 14, relief hole 15, the flat gate valve 16 of blanking, shaft 17, cylindrical shell 18.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Among Fig. 1, after motor 2 starts, power drives shaft 17 and stirrer paddle 8 rotations through decelerator 3, plant dry material through segmentation enters the ground floor extractor by feeder 1, close after reaching specified quantity, open 6 pairs of dry materials of microwave generator and carry out irradiated heat when regulation requires, solvent is by solvent pump P
1Material is extracted from the reverse extractor that is pressed in bed of material bottom through advancing solvent gate valve 10, filter screen cavity 9.After reaching the stage process requirement, mixed liquor is at vavuum pump P
2Discharge through discharge opeing gate valve 11 under the vacuum suction that produces, open the flat gate valve 16 of blanking then, material is driven by stirrer paddle and falls into second layer extractor through relief hole 15, meanwhile ground floor begins charging, irradiated heat and the extraction operation of a new round again, thereby reaches the purpose of relative continuous extraction.
Material repeats said procedure and extracts in the second layer and following each layer, the material slag is discharged through discharge gate 14 after reaching the overall craft requirement.
Shaft is provided with the sealing axle sleeve of being made by polytetrafluoroethylmaterial material 12 at mistake layer place, to guarantee that supernatant liquid does not leak to lower floor;
Protective cover 5 is made by the material that can prevent microwave leakage.
Solvent provides pressure by solvent pump P1, and the filter screen that recoils when entering each layer extractor is to reach the cleaning purpose.
The negative pressure that mixed liquor is produced by vavuum pump P2 is extracted out and is entered the distillation enrichment process.
Enter after the material slag is discharged to steam to take off and reclaim solvent and drying process.
Above-described is preferred embodiment of the present invention, and the number of plies of device can increase and decrease, all within protection scope of the present invention by extraction subject matter extraction process condition enactment.
