Abstract

The invention relates to a continuous microwave solid-liquid extracting system, wherein it comprises a hollow chamber (1) with outside microwave magnetic control tube (4), an extracting room (7), and a solid-liquid transmitter; the transmitter is formed by transmission blade (14), rotation axle (8) an the motor driving axle (8) and speed changer (10) that in the extracting room (7) and connected to the rotation axle (8); the extracting room (7) is incline; the bottom of transmitter has solid inlet (3) and liquid outlet (15); the top has solid slag outlet (12) and solvent medium inlet (5); the extracting room is in the hollow chamber (1); the inlet (3), liquid outlet (15), inlet (5) and slag outlet (12) via chamber (1) are connected to the room (7). Compared with present technique, the invention has high microwave utilization and low energy consumption.

Description

Technical field [0001] The invention relates to a microwave extraction device, in particular to a continuous microwave solid-liquid extraction system with compact structure, low energy consumption and high efficiency, which can realize continuous operation of the microwave extraction process. Background technique [0002] The traditional classic solid-liquid extraction method mainly uses water or organic solution as the solvent, and uses steam to directly or indirectly heat the solids and extract the effective ingredients. With the development of microwave technology, microwave technology is gradually applied to strengthen the solid-liquid extraction process. However, the microwave extraction process is batch-type, and industrial production cannot be realized. Chinese invention patent CN1273206C proposes a device that can realize continuous microwave extraction. The device includes a microwave heater and a solid-liquid transmission device. The microwave heater is a hollow cavity ...
