Microwave extraction
    The frequency range of the microwave electromagnetic wave between 300MHz 300GHz , with a strong penetration and a high heating efficiency . The penetration depth of the microwave wavelength of the microwave in the same magnitude , frequency of 30MHz 300GHz microwave wavelengths is 100cm 0.1cm, by microwave heating , the microwave can penetrate the material and direct both the external and internal heating .
Traditional Chinese medicine extraction workshop generally have boiled mention , concentration , concentration
    Recovery and extract drying process , has been formed under the current domestic pharmaceutical processing equipment, microwave equipment for use primarily in the extraction and extract the drying process to achieve , and this article focuses on the application of microwave extraction equipment .
    Microwave extraction refers to the extraction of natural medicine active ingredients extracted before or during the introduction of the microwave field treatment , the use of the microwave field to enhance the features and characteristics of a new active ingredient leaching extraction method . Microwave extraction with high selectivity, short operation time , less solvent consumption , high yield active ingredients , no noise , suitable for thermally labile components in a short time and can inactivate hydrolytic enzymes herbs advantages , based some research results , microwave extraction can be applied to water extraction, alcohol and volatile oil extraction process .
    Microwave extraction equipment replacement multifunctional extraction tank to replace traditional microwave heating steam heating , eliminating the high-temperature heat and thermal gradients , extraction temperature is low , easy to paste , fast, with less solvent , low operating costs, controllable .
