Microwave extraction equipment in Design
     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 order of magnitude as the wavelength of the microwave frequency and respectively , 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 and recovery and extract drying process , has been formed under the current domestic pharmaceutical processing equipment, microwave equipment utilization primarily in the extraction and extract the drying process to achieve, and this 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 . Under the existing equipment and the tea extract ammonia base , Tan and other production experience .
