The specific embodiment 1

As shown in Figure 1: the helical axis 12 in power-equipment 1 and the combined barrel 8 is rotationally connected, combined barrel 8 levels crouch and put, on the middle and upper part of the combined barrel 8 that combined barrel 8 is connected with power-equipment 1, extracting liquid outlet 2 is set, on the combined barrel 8 on the right of extracting liquid outlet 2, vertical cast feeder 4 is set, be conical, up big and down small, rotating shaft 5 is set in it, rotating shaft 5 tops are connected with several loose metal spares 3, are two loose metal spares 3 in this example, the fixedly connected spiral plate 6 in its underpart, be communicated with the dog-house 7 of combined barrel 8 herein, as shown in Figure 4; In the bottom of combined barrel 8, its outside connects heat carrier import 24, heating medium outlet 23 respectively with on heating jacket 9 folders on the heating jacket 9, and heating jacket 9 can be with on several sectional splint; On the top of combined barrel 8, door closure 10, visor mouth 11, indirect steam outlet 16, solvent import 17 are set, door closure 10 can open or close, and door closure 10, visor mouth 11, indirect steam outlet 16 can be provided with several on combined barrel 8 respectively; In the bottom of combined barrel 8, can several blowdown valve ports 20 be set segmentation; In combined barrel 8, segmentation is provided with several baffles 15, and scavenge pipe 13 is set; Intermediate supports 14 wherein, flange 21 adopts segmentation to connect because combined barrel 8 is long, so flange 21 couples together the combined barrel 8 of segmentation, and intermediate supports 14 couples together helical axis 12 and supported; The other end at combined barrel 8 connects vertical discharger 18, and slag notch 19 is arranged on it; Extracting liquid outlet 2 at combined barrel 8 is continuous porous spiral plate 25 to the helical axis 12 between the dog-house 7, and as shown in Figure 2, all the other are the structure of continuous porous spiral plate 25 or continuous hurricane band 26, as shown in Figure 3; The cross section of the combined barrel 8 from the extracting liquid outlet on the combined barrel 82 to dog-house between 7 is cylindrical, and as shown in Figure 2, the cross section from dog-house 7 to the combined barrel 8 between the solvent import 17 takes the shape of the letter U, as shown in Figure 3.

During work, material (Chinese medicine) joins in the combined barrel 8 from vertical cast feeder 4, rotating shaft 5 tops have been connected brokenly the effect that material is built bridge in the vertical cast feeder 4 with loose metal spare 3, the effect that is connected the blanking of (welding) amount of starting to control of rotating shaft 5 bottoms and spiral plate 6, its power can be provided or provided in addition by power-equipment 1, power set 1 drive helical axis 12, thereby slowly stirring and promote material advances to the other end in combined barrel 8 from left to right, heating jacket 9 heats the material in it, because combined barrel 8 diameters are less, so during heating, the material of center has a narrow range of temperature in the material at combined barrel 8 inwall places and the combined barrel 8, so heating-up temperature does not need too high, and material is stirred in combined barrel 8, so material is heated evenly, satisfies the needs that low temperature extracts, generally speaking, heating-up temperature gets final product at the 90-100 degree; The solvent import 17 on the top of combined barrel 8 opposite sides, because this solvent import 17 links to each other with vertical discharger 18, and material is from vertical discharger 18, be discharged from the slag notch 19, solvent adds from solvent import 17, with material effect in the combined barrel 8 and produce soup, soup is from right to left to extracting liquid outlet 2 directions slowly advance (negative line feed), until arriving and freely flowing out from extracting liquid outlet 2, the power of advancing is difference in height, be that extracting liquid outlet 2 is than solvent import 17 low (low slightly getting final product), therefore in combined barrel 8, just exist the relative velocity motion of solvent and storeroom, be continuous flow upstream, make on each end face, all to exist certain concentration gradient that diffusion boundary layer is thin and upgrade fast, and then make the leaching rate of the effective ingredient in the material improve greatly, satisfy the requirement of pharmaceutical production GMP.Continuous porous spiral plate 25 in the U-shaped section of combined barrel 8 or continuous hurricane band 26 are selected to use according to the characteristic of material, play to promote and stir material and advance, and allow soup oppositely pass through to extracting liquid outlet 2 simultaneously; Continuous porous spiral plate 25 in the cylindrical sections of combined barrel 8 prevents that material (dregs of a decoction) from oppositely flowing out from extracting liquid outlet 2 from right to left; In extracting the material process, can monitor by several visor mouths 11,10 pairs of each section materials of door closure, waste liquid can be discharged from several blowdown valve ports 20, organic solvent or aromatic oil can export 16 from indirect steam and reclaim, baffle plate 15 prevents material by solvent oppositely passing from right to left, and scavenge pipe 13 waters or the water under high pressures that are arranged in the combined barrel 8 clean salvage stores (dregs of a decoction) in combined barrel 8.

The specific embodiment 2

As Fig. 1, Fig. 5, shown in Figure 6: combined barrel 8 turns at the other end, form the U type, the structure at turning is that vertical discharger 18 is from combined barrel 8 dischargings the last period and to curving another section combined barrel 8 chargings of returning, an end that curves the combined barrel 8 of returning at this section is provided with power set 1, form U type structure, soup tube connector 27 is carried the soup in the back segment of combined barrel 8 to the leading portion of combined barrel 8, freely flow out at 2 places until extracting liquid outlet, and all the other are identical with the specific embodiment 1.

The utility model also can be used for other natural materials are comprised that natural plants etc. extracts.
