Microwave Extraction Equipment:
Microwave extraction process is the extraction medium frequency electromagnetic waves penetrate the material to reach the internal micro-tubes and glandular cell system process. Due to the absorption of microwave energy, the temperature inside the cell will increase rapidly, so that the internal pressure exceeds the cell wall to the capacity expansion, the cells rupture, the active ingredients which flow freely, and at a lower temperature was dissolved in extraction medium. By further filtration and separation, to obtain the desired extract.
The electromagnetic field generated by the microwave can accelerate the molecular components are extracted from the solid liquid interface internally to the rate of diffusion. For example, with water as solvent, under the action of the microwave field, the water molecules by the high speed rotation state to the excited state, which is a high energy unstable state. At this point the water vapor molecules or to enhance the driving force of the extracted components, or release their excess energy to the ground state, the energy released will be passed to other molecules of the substance to accelerate their thermal motion, thereby reducing the extracted components internal diffusion of molecules from the solid to solid-liquid interface of the time, resulting in extraction rate increased several times, and can reduce the extraction temperature, the maximum guarantee of quality extracts.
Since the frequency of the microwave frequency of rotation associated molecules, so the microwave energy is a dipole by an ion migration and molecular motion caused by the rotation of the non-ionized radiation, when it acts on the molecule, the molecule can promote the rotational movement If the molecule has a certain polarity, to the action of the microwave field produce instantaneous polarization, and 2.45 billion times / s speed for polarity inversion motion, resulting keys vibrations tear and particles friction and collisions, and quickly generate a lot of heat, promote cell rupture, the cell fluid overflow and spread to the solvent. In the microwave extraction, the absorption of microwave differences in the ability of certain substances can make the base areas or certain components of the extraction system are selectively heated, so that the material was extracted from the matrix or the system is separated into a smaller dielectric dielectric constant, the relatively poor absorption of microwave extraction solvent.
Microwave extraction equipment features:
Microwave are volatile, high frequency, thermal and non-thermal characteristics features four characteristics, which determines the microwave extraction has the following characteristics:
A reagent consumption, energy saving and pollution.
2 microwave heating uniformity, and higher thermal efficiency. Heat extraction is based on the traditional heat conduction, heat radiation, etc. from the outside in heat transfer, while the microwave extraction is a "body heating" process, that is heated both inside and outside, and thus uniform heating, high thermal efficiency. Microwave extraction without heat source, thus removing the temperature gradient, and the fast heating, the material of the heating time is short, which is conducive to the extraction of heat-sensitive material.
3 microwave extraction there is no thermal inertia, and thus the process is easy to control.
4 microwave extraction without drying pretreatment, simplifying the process, reducing the investment.
5 of handling large quantities of microwave extraction, extraction efficiency, saving time. With the traditional solvent extraction, can save 50% to 90% of the time.
6 microwave extraction selectivity is better. Because microwave extraction of material can be selectively heating the different components, and therefore the target component and the substrate can be directly separated to thereby improve the extraction efficiency and product purity.
7 microwave extraction results from the impact of material moisture content, high recovery.
Based on the above characteristics, microwave extraction often referred to as the "green extraction process."
