Abstract
The utility model relates to a low temperature microwave extractor, which is mainly composed of a clamping sleeve type heat exchanger, a microwave irradiation pipe, a solid-liquid separating device and a condensing and heating device, wherein the clamping sleeve type heat exchanger, the microwave irradiation pipe and the solid-liquid separating device are connected in sequence. The condensing and heating device is respectively connected with an interlayer sleeve pipe of the clamping sleeve type heat exchanger and a ventilation pipe of the solid-liquid separating device. The utility model can ensure that the utility model has high extraction rate and high selectivity under a low extraction temperature to obtain concentration extracting materials of effective components in a natural product with high quality and low cost.
Description
Technical field
The present invention relates to the extract and separate device, specifically is the low-temperature microwave extraction equipment that is specially adapted to the extraction and the separation of active ingredient in the natural products.
Background technology
The industrialization extraction separation method of effective ingredient mainly comprises in the natural products at present:
1, steam distillation method, so temperature is higher in the method, may destroy the heat-sensitive ingredients in the natural products, also be difficult to the more lower boiling composition of complete acquisition, thereby recovery rate is lower, extraction is limited in scope;
2, supercritical extraction, though effect is better, equipment cost and running cost are higher, are difficult to take into account the factor of extraction quality and economic benefit two aspects;
3, solvent hot extraction process is difficult to the effective ingredient in the stripping natural products when lower temperature, higher temperature then makes lower boiling composition scatter and disappear or destroys heat-sensitive materials.
Natural products extract for high-quality had both required comparatively complete composition, improved again as far as possible and extracted productive rate, reduced the extract and separate cost, and existing method is difficult to satisfy this requirement.
The utility model content
The purpose of this utility model is the defective at the prior art existence, providing a kind of specifically is the low-temperature microwave extraction equipment that is specially adapted to the extraction and the separation of active ingredient in the natural products, to guarantee under lower extraction temperature, higher extraction yield and higher selectivity are arranged, thereby obtain high-quality, the concentrated extract of active ingredient in the natural products cheaply.
Low-temperature microwave extraction equipment of the present utility model, mainly constitute by jacketed heat exchanger, microwave irradiation pipe, solid-liquid separator and condensation, heater, jacketed heat exchanger, microwave irradiation pipe, solid-liquid separator connect successively, and condensation, heater are connected with the interlayer sleeve pipe of jacketed heat exchanger, the airway of solid-liquid separator respectively.
The interlayer sleeve pipe of jacketed heat exchanger by be connected with condensation, heater obtain different temperatures medium to regulate wherein material temperature;
The material that jacketed heat exchanger comes out is accepted the microwave uniform irradiation through the microwave irradiation pipe, frequency electromagnetic waves penetrates and is extracted material, make cell rupture at a lower temperature, make wherein that effective ingredient freely flows out, thereby guaranteed lower extraction temperature, higher selectivity and higher extraction yield; The time that material circulates in the microwave irradiation pipe and the degree of microwave irradiation are adjustable, to regulate extraction yield;
The material that solid-liquid separator comes out to the microwave irradiation pipe carries out the crude separation of solid-liquid two-phase, and filter screen in this solid-liquid separator and pressue device can help separating of slag and extract;
For material temperature better and in wider control jacketed heat exchanger, the interlayer sleeve pipe of jacketed heat exchanger connects condensate pipe, steam pipe or the hot-water line of condensation, heater respectively by control valve, come temperature of charge is controlled by connecting thermal source and low-temperature receiver, make solvent or volatile materials by the condenser cooling for reflux, thereby guarantee that each composition can not run off in the material; Simultaneously whole system is communicated by condenser with atmosphere, guarantee that the safety of extraction is carried out.
For extract is clarified fully, solid-liquid separator also need connect centrifuge, makes parting liquid become clear liquid.
For clear liquid is concentrated, centrifuge is connected with jacketed heat exchanger, and jacketed heat exchanger at this moment becomes concentration tank, and the clear liquid that centrifuge is come out enters jacketed heat exchanger, and control valve is communicated with heater, parting liquid is heated concentrated; The steam of heater enters condenser,, emits through outlet and concentrate the product that obtains in the jacketed heat exchanger as reclaiming solvent through cooling.
The utility model compared with prior art has following advantage:
1, satisfies the extract and separate condition of active ingredient in the multiple natural products;
2, separate the extract ingredient obtain and enrich completely, be particularly suitable for the extract and separate of aroma type fragrance material; The extract and separate that also is suitable for water-soluble or liposoluble constituent can more intactly be preserved the natural characteristic of various active components because of lower temperature;
3, low-temperature treatment plant combines with microwave abstracting, makes equipment not be subjected to the restriction of region temperature, conveniently founds the factory in various places;
4, be easy to implement, equipment cost and production cost are all cheaper, are suitable for being extended to suitability for industrialized production.
