Description

The Chinese medicine digester

Technical field

The present invention relates to the leaching device of Chinese medicine.

Background technology

From Chinese herbal medicine, extract its effective ingredient, method in common has infusion process, decocting method and percolation, wherein the used equipment of infusion process has cylinder, altar or the macerator of rabbling mechanism is housed, the used equipment of decocting method has marmite, jacketed pan, boiling machine or multipotency formula Chinese medicine extraction jar, the used equipment of percolation has percolation vat, pressurization percolating device, double-countercurrent percolating device or continuous diffusion device, these above-mentioned devices, its common deficiency is that the medicinal residues liquid content is many, extraction time is long, and the solvent expense is big.Development along with traditional Chinese medical science pharmaceutical technology, many inventors study and improve the extraction equipment of Chinese medicine, some new technical schemes have been proposed, as application number 99113177 " low-temperature dynamic is soaked into the quick solid-liquid separation of level Four and extracted unit ", realized the cleaning and sterilizing of medical material is separated and merges automatically separating medium and finish continuously in same unit with pulverizing, dynamically leaching fast, level Four solid-liquid separation, clarification, the automaticity height, but equipment complexity, cost height, solvent expense are still very big; The patent No. is 98248372 " a kind of gutta-percha diffuser ", comprise a cylindrical shell, the pipe spreader and the composite filter net tube of band stirring paddle and spray apertures are housed in the cylindrical shell, the cylindrical shell bottom is the slag-draining device of band side sieve plate, though this diffuser is simple in structure, but still needing a large amount of solvents, extraction time is long.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structure, the solvent expense is few and extraction time is short Chinese medicine digester.

This Chinese medicine digester, comprise by filtering the rotatable leaching tank of driven by motor, the tube that inserts from the top is housed in the inner chamber of leaching tank, on the hypomere of tube agitator is housed, the part that tube is positioned at the leaching tank inner chamber is densely covered with the fluid aperture, the upper end of tube is communicated with mixing tube by a sliding sleeve, the other end of mixing tube is communicated with solvent pipe and steam pipe, tube is positioned at leaching tank one section last drive mechanism that passes through outward and is connected with stirring motor, the bottom surface of leaching tank is provided with the fluid mouth of pipe, the inner bag that is constituted and supported by filtering material is housed in the inner chamber of leaching tank, its construction features is that interior cholic outer surface abuts on the medial surface and inner bottom surface of leaching tank, and the medial surface and the inner bottom surface of leaching tank are provided with guiding gutter.

Above-mentioned agitator comprises two kinds of structures, and a kind of is the stirring paddle affixed with tube, and another kind is the stirring paddle affixed with tube, and the outer end of stirring paddle is connected to the active fan wing.

The internal diameter of above-mentioned leaching tank, up big and down small.

The groove depth of above-mentioned guiding gutter, last shallow down dark, guiding gutter comprises three kinds of structures, and first kind is linear in the shape of a spiral, and second kind is made of skewed slot and the vertical slots that is communicated with skewed slot, and the third is a vertical slots.

As improvement to the Chinese medicine digester, filter motor and stirring motor and be installed on the frame, the lifting linking member that is connected with mixing tube also is housed on the frame.

As the further improvement to the Chinese medicine digester, the lower end of tube is connected to pressure valve, and its effect is that this valve is opened automatically, imports solvent fast in leaching tank, closes automatically again after pressure reduces when the pressure of solvent in the tube strengthens.

During use, inject an amount of solvent earlier in leaching tank, the Chinese crude drug or the prepared slices of Chinese crude drugs after will pulverizing are put into leaching tank again, open solvent pipe and steam pipe then, and adjust the two flow, make solvent be raised to the needed temperature of lixiviate, connect the stirring motor power supply again, tube drives the agitator rotation, under bump, cutting and the stirring action of agitator, the very fast quilt of composition in the Chinese crude drug leaches, and dissolves in the solvent, forms medicinal liquid; After the leaching operation is finished, disconnect the stirring motor power supply, open the fluid mouth of pipe again and connect the filtration motor power, filtering leaching tank high speed rotating under the driven by motor, under action of centrifugal force, medicinal residues in the inner bag and medicinal liquid are got rid of outward, but owing to interior cholic the stopping that constitutes with filtering material, medicinal residues are blocked in the inner bag, and medicinal liquid gets rid of in the guiding gutter of leaching tank by inner bag, flow out from the fluid mouth of pipe through guiding gutter, the realization medicinal liquid separates with medicinal residues again.Above-mentioned step can repeat according to needs.

Chinese medicine digester of the present invention is finished with medicinal liquid is separated in same leaching tank with medicinal residues owing to solvent the composition in the Chinese crude drug is leached, forms medicinal liquid, thereby simple in structure; Because the gap between inner bag and leaching tank medial surface, the inner bottom surface is a guiding gutter, make that filtered liquid medicine is very fast to flow out in leaching tank, thereby reduced the consumption of solvent, improved liquor strength, for taking, patient provides convenience; Carry out lixiviate owing to can each flavor Chinese crude drug be pulverized the back in advance with the high temperature solvent according to the principle that the efficacy of a drug goes out altogether, thereby extraction time is short, the efficient height, the outpatient is taken at short notice according to the made Chinese medicine preparation of doctor formula becomes possibility, has exempted the trouble of being in after the outpatient gets it filled from the liquid of boiling medicine; Also owing to adopted centrifugal filtration, the content of medicinal residues herb liquid is greatly reduced, has improved the rate of taking of medicinal liquid, thereby reduced the consumption of the Chinese crude drug of respectively distinguishing the flavor of in the prescription, reduced patient's medication expense, saved herb resource, and standard middle medical drugs.
