Detailed description of the invention
Embodiment 1
As shown in Figure 1, present embodiment discloses the efficient extracting system of a kind of Chinese medicine standardization, this system comprises extractor system 100, the computer control system 200 controlling extractor work, the Effective Component of Chinese Medicine that extractor system 100 extracted carry out the packing machine 300 packed and the appliance for applying carbon dioxide 400 providing carbon dioxide to extractor.
As shown in Figure 2, this extractor system 100 comprise extractor and be arranged in extractor for the pulverizer 101 of fast-crushing Chinese medicine, for heat fluid temperature in extractor heater 102, for gather fluid temperature in extractor temperature sensor 103, for gather the fluid density of Chinese medicine extraction process supersonic detector 104, for carrying out the ultrasonic transducer 105 of extract and separate and the pressure sensor 106 for gathering extractor internal gas pressure to solution.
Wherein, the ultrasonic detection technology that supersonic detector 104 adopts is a kind of detection technique of quick nondestructive, and this technology judges the physics and chemistry character of material by detecting interactional type and degree between low-yield ultrasonic and material.Compared with other detection methods, ultrasound detection has the advantage of its uniqueness: non-destructive, fast, accurately, easily be automated with cheap, and can detect enriched sample and light opacity material.
Wherein, ultrasonic transducer 105 is a kind of devices that high-frequency electrical energy can be converted into mechanical energy.Mechanical oscillation are converted electrical signals to by the piezo-electric effect of material.Ultrasonic transducer is a kind of energy conversion device, and its function the electrical power of input is converted to mechanical output (i.e. ultrasonic wave) to pass again, and a part of power that autophage is little.The present invention utilizes ultrasonic technology to strengthen extraction and isolation process, can effectively improve extraction and isolation rate, shortens extraction time, cost-saving, the Quality and yield that even can also improve product.
Wherein, a Chinese medicine extraction parameters database is provided with in computer control system 200, Chinese medicine extraction parameters databases contains the plurality of Chinese title standard extraction parameter corresponding with this Chinese medicine, and described extraction parameters comprises standard extraction temperature, standard extraction pressure and standard extraction fluid density.This Chinese medicine extraction parameters database collects storage in advance, so-called standard extraction temperature standard extraction liquids density, it is exactly extraction parameters best in theory, these parameters by experiment or existing data can know, if this data volume is enough huge, substantially can be general in most Chinese medicine extraction.Temperature is the important parameter in Chinese medicine extraction process, if temperature is too low, may be difficult to extract active ingredient, if temperature is too high, may active ingredient be destroyed, and optimum temperature difference when different Chinese medicine extracts, so this temperature needs to control relatively accurately.The present invention is in order to improve effect of extracting, be provided with an appliance for applying carbon dioxide especially, the change of the flow of CO2 has the impact of two aspects on extraction, the flow of CO2 is too large, CO2 flow velocity in extractor can be caused to increase, CO2 shorter residence time, to reduce with extract, be unfavorable for the raising of extraction yield time of contact.But then, the flow of CO2 increases, and can increase the mass transfer force of extraction process, correspondingly increase mass tranfer coefficient, mass transfer rate is accelerated, thus improves extracting power.Therefore, the flow of choose reasonable CO2 is also quite important, and the present invention comes indirect inspection and this technical characteristic of indicator by pressure parameter.The present invention is in order to improve extraction efficiency further, and the present invention, by grasping fluid density parameter, indirectly controls extraction material granular size, allows rate of extraction be improved.
As shown in Figure 2, this device systems is in extraction process, and computer control system 200 first recalls standard extraction temperature, standard extraction pressure and the standard extraction fluid density corresponding to current extraction Chinese medicine title according to user instruction in described Chinese medicine extraction parameters database, then, the fluid temperature collected is transferred to computer control system 200 by temperature sensor 103, described fluid temperature and standard extraction temperature compare by computer control system 200, and close to standard extraction temperature with the fluid temperature adjusted in extractor according to comparative result control heater 102 action, the tank internal gas pressure that pressure sensor 106 collects by computer control system and standard extraction pressure compare, and make tank internal gas pressure close to standard extraction pressure according to the action of comparative result control appliance for applying carbon dioxide 400 to increase or to reduce carbon dioxide supply, the fluid density collected is transferred to computer control system by described supersonic detector, described fluid density and standard extraction fluid density compare by described computer control system, and regulate pulverizer rotating speed close to standard extraction fluid density with regulates liquid density according to comparative result according to following formula: V=[500+1000 (ρ 1-ρ 2) liter/kilogram] rev/min, ρ 1 is standard extraction fluid density, the fluid density that ρ 2 arrives for Real-time Collection, such as ρ 1 is 1.8 kg/liter, ρ 2 is 1.2 kg/liter, then V=[500+1000 (1.8 kg/liter-1.2 kg/liter) rise/kilogram] rev/min=[500+1000*0.6] dress/minute=1100 rpms, the rotating speed of dynamic change is particularly conducive to the granularity changing material, certainly the density changing liquid is conducive to, and then the efficiency of directly impact extraction.
