Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of extraction device, more particularly to a kind of microwave extraction device for extraction of picropodophyllin. BACKGROUND

[0002] Picropodophyllin is extracted from the plant of picropodophyllum, and it is a kind of lignan antitumor component, which has the pharmacological effects of inhibiting herpes virus and inhibiting mitosis in cell metaphase. Therefore, it is widely used in the field of medicine, especially for the treatment of toxic venereal disease and some tumors. The microwave extraction device is not only suitable for the extraction of picropodophyllin, but also can be widely used in the extraction of other natural medicines, functional substances and nutritional components, such as food industry, medicine field, environmental protection field and agriculture.

[0003] The existing technology has the following disadvantages: the stirring effect is not good, which means that the mixing between the solvent and the material is not sufficient, which will directly affect the extraction efficiency. In the process of microwave extraction, the solvent needs to fully soak the material and effectively contact the picropodophyllin inside, so as to realize efficient extraction. If the stirring is uneven, the contact area between the solvent and the material will be limited, which will lead to the decrease of extraction efficiency. After a long time of use of the stirring device, picropodophyllin and other impurities are easily left. These residues provide a breeding environment for bacteria. If not cleaned in time, bacteria may multiply in large quantities, which will pollute the subsequent extraction process. Manual cleaning of the stirring device takes a long time, which will affect the continuous use of the equipment and the production efficiency. Especially during the peak production period, the extension of cleaning time may cause production delay. UTILITY MODEL CONTENTS
