Description

A device for extracting Chinese herbal medicine

technical field

The utility model relates to the technical field of separation devices, in particular to a Chinese herbal medicine extraction device.

Background technique

The chemical composition contained in traditional Chinese medicine is very complex. It contains a variety of active ingredients, ineffective ingredients, and toxic ingredients. Extracting its active ingredients and further separating and purifying them to obtain effective monomers is an important content in the field of traditional Chinese medicine research. The extraction of traditional Chinese medicine is to use some techniques to extract the active ingredients to the maximum extent, so as to improve the internal quality of traditional Chinese medicine preparations and the clinical treatment effect, so that the effect of traditional Chinese medicine can be maximized.

The extraction of whole plant components is another new direction of technological development. Traditional Chinese medicine has always used all Chinese herbal medicines as medicines to decoct. Modern medicine extracts a certain ingredient in Chinese herbal medicine. In the first few years, this ingredient is very effective for certain symptoms or bacteria, but after a period of time, the therapeutic effect of these ingredients on symptoms will decrease, and the bacteria will also produce antibodies . This is not the case when the whole ingredients of Chinese herbal medicines are crushed and used for treatment. On the other hand, some diseases can be treated by using certain extracted ingredients in Chinese herbal medicine, and these ingredients are themselves toxic, and eating too much will cause harm to the human body. However, if all the components of the plant are eaten together as a medicine, the therapeutic effect will remain unchanged, and other components contained in the plant will alleviate the toxicity of the therapeutic component. In terms of food and health care products, while extracting a certain active ingredient in plants, other ingredients left in the plant are wasted, and these wasted ingredients often contain many substances that are beneficial to the human body. Therefore, the whole-component extraction of plants is of great significance. However, the extraction rate of the whole components of the existing Chinese herbal medicine extraction device is not high, so the development of a Chinese herbal medicine extraction device with a high extraction rate has become an urgent technical problem to be solved.

The use method of a Chinese herbal medicine extraction device provided by the utility model is as follows:

1. Sterilization of pipelines

Open the Q8 valve, Q5 valve and Q7 valve, the steam on the gas pipeline passes through the steam filter 42 and then enters the sterilization filter 44. In the process of emptying, the Q3 valve at the lower end of the sterilizing filter 44 and the exhaust valve Q4 should be slightly opened to remove the condensed water. The emptying time should last for about 30 minutes. When the equipment is used for the first time or started after long-term non-use, it is best to use intermittent emptying, that is, after the first emptying, it will be emptied every 3 to 5 hours to eliminate spores. The steam filter 42 and the sterilizing filter 44 after being evacuated should be air-dried for about 20-30 minutes, and then the valve should be closed. Since the pressure reducing valve 43 cannot be steam sterilized, the Q9 and Q6 valves are not opened.

2. Empty fermentation tank

Before the fermentation tank is empty, open the drain valve Q13 (so that the pressure in the jacket does not exceed the pressure), close Q3, slightly open Q4, open the steam valve Q2, open Q1 to pass steam into the tank; open Q10, Q11 to pass The sampling port passes steam into the tank.

Open the feed port 16 on the tank, the exhaust valve Q16, and the valve Q13 on the sewage pipeline slightly, so that the steam is discharged through these valves. When the humidity reaches 122 ℃, the timing starts, and the opening of the valves Q16, Q1, and Q10 are adjusted. , Keep the temperature in the tank at 122 ℃ ~ 128 ℃ (the pressure is generally 0.11 ~ 0.15Mpa), and the temperature and pressure of the air consumption can be adjusted according to the process.

When the time reaches 30 to 40 minutes, close Q1, Q4, Q10, then close Q2 and Q11, open the valves Q3 and Q1 on the intake pipeline, and let the air cool in the tank, so that the positive pressure in the tank is kept at 0.03MPa-0.05 between MPa.

When rapid cooling is required, close the blowdown valve Q13, open the water inlet valve Q14 to pass cooling water to the jacket for cooling, and close the cooling water after reaching normal temperature. Under special circumstances, intermittent emptying can be used (and then emptying every 3 to 5 hours to eliminate spores).

3. Add medium and inoculate

(1) After emptying, close the air inlet valve Q1, open Q16 to remove the pressure in the tank, add Chinese herbal medicine and the wall-breaking reaction solution into the fermenter, so that the Chinese herbal medicine is immersed in the wall-breaking reaction solution.

(2) Turn on the mechanical stirring device and rotate at low speed to mix the materials in the tank evenly.

(3) Open the jacket blowdown valve Q13 and the steam valve Q10, and preheat the culture medium in the tank (using jacket steam preheating) to preheat to 50-60°C; or inject heat into the jacket of the fermentation tank water to keep the temperature at 50-60°C;

(4) Then use the combination of inert gas (argon) and ultrasonic waves to inactivate and extract the Chinese herbal medicine. Specifically:

Open the valves Q9, Q6, Q3, Q1, pass in an inert gas (such as argon) through the gas pipeline, and simultaneously open the ultrasonic device 3 to carry out ultrasonication until the added inert gas volatilizes, and the ultrasonication ends, (the Chinese herbal medicine separation device of the present utility model).
