Embodiment 1

[0042] Such as figure 1 As shown, the embodiment provides an ultrasonic and microwave extraction system for extracting Chinese medicinal materials or plant active substances, including a closed box 1 with an openable upper cover, and an openable entrance arranged inside the closed box 1 The sample solution device 2 is located between the sample solution device 2 and the box 1 and is attached to the side wall of the sample solution device 2. A circulating cooling device 3 with a cooling liquid inlet 31 and a cooling liquid outlet 32 , also includes a movable microwave introduction device 5 arranged on the sample solution device 2, a movable ultrasonic introduction device 6 and a coordinated control device 7, and the coordinated control device 7 includes a PLC controller 70 and can be controlled with the PLC 70, the microwave introduction device 5 and the first alarm device 71, the second alarm device 72, and the third alarm device 73 that feed back the work of the ultrasonic in...

Embodiment 2

[0054] This embodiment provides an ultrasonic and microwave extraction system, which is a deformation based on Embodiment 1, such as image 3 As shown, the improvement of the extraction system provided in this embodiment relative to Embodiment 1 is that: the sample solution device 2 is a cuboid cavity, and the microwave introduction device 5 has an even number of Microwave inlets 51, an even number of microwave inlets 51 are distributed in pairs at the two ends of the diagonal of the space formed by the sample solution in the cavity with the farthest distance. The two microwave inlets 51 are distributed in pairs at the two ends of the diagonal of the space formed by the sample solution in the cavity with the farthest distance. This makes the microwaves imported from the two microwave inlets 51 respectively intersect with the ultrasonic waves after the ultrasonic waves are introduced, and the intersection points are located at two opposite ends of the same plane. Enhanced, and...

Embodiment 3

[0060] This embodiment provides an ultrasonic and microwave extraction system, which is a deformation based on Embodiment 1 or 2. In this embodiment, as Figure 4 As shown, the microwave introduction device 5 includes a magnetron 53 , an excitation system, a feedback system (not shown in the figure) and a cooler 54 . The output frequency of the magnetron 53 is 2450MHz, the average output power is 6kW, and the maximum output power is 10kw. There are two sets of excitation systems, one is the electromagnet wire package that comes with the magnetron, and the other is the coil that is wrapped by enameled wire and placed outside the magnetron wire package of the magnetron. These two parts have special excitation The power supply, the electromagnetic current in the electromagnet wire package is about 8.0A, and the size of the current in the external coil can be adjusted by the coordinated control device 7 . The feedback system has two parts, one part is to input the anode current i...

Abstract

The invention provides an ultrasonic microwave extraction system for Chinese medicinal materials. The ultrasonic microwave extraction system is provided with a coordinated regulation and control device, and the coordinated regulation and control device is provided with a first alarm device, a second alarm device and a third alarm device. The coordinated regulation and control device controls a microwave introduction device to introduce microwaves, the first alarm device sends an alarm signal to the coordinated regulation and control device after a certain time, and the coordinated regulation and control device controls an ultrasonic introduction device to introduce ultrasonic waves; after a certain time, the second alarm device sends an alarm signal to the coordinated regulation and control device, and the coordinated regulation and control device controls the microwave introduction device and the ultrasonic induction device to change the operating power, so that the operating power ofthe microwave introduction device and the ultrasonic induction device is lower than initial power of the microwave introduction device and the ultrasonic induction device, respectively; and the thirdalarm device sends an alarm signal to the coordinated regulation and control device after the microwave introduction device and the ultrasonic introduction device operate for a certain period of timeunder the condition of the changed operating power, and the coordinated regulation and control device firstly controls the microwave introduction device to stop working, and then controls the ultrasonic introduction device to stop working.

Description

technical field [0001] The invention relates to an ultrasonic and microwave extraction system and an extraction process of traditional Chinese medicinal materials, belonging to the technical field of extraction of useful components of traditional Chinese medicinal materials. Background technique [0002] The natural active ingredients in plants or traditional Chinese medicine have broad application prospects in the fields of medicine, food, chemical industry, cosmetics, feed and so on. The preparation of traditional Chinese medicine extracts, fluid extracts or biologically active substances in the pharmaceutical industry and the preparation of plant-derived functional additives in the food, cosmetics, and feed industries all require the use of extraction equipment; in the field of chemical and chemical analysis, sample pretreatment or Processes such as sample preparation and chemical synthesis may also require the use of digestion, extraction equipment or reactors. [0003]...
