Problems solved by technology

[0004] For the vacuum concentrator used in the above-mentioned drug extraction device, the total vacuum tube is located close to the collected condensate, so the vacuum system can easily suck out the collected condensate (solvent) through the total vacuum tube, which not only causes the loss of solvent, but also easily Damage to vacuum equipment
[0005] Furthermore, the vacuum concentrator use

Embodiment 1

[0055] The drug extraction device described in this embodiment is as figure 1 and 2 As shown, it includes a first extraction tank and a first concentrator, the first extraction tank is provided with a solvent inlet and a liquid outlet, and the first extraction tank is any commercially available drug extraction tank, in this embodiment , the solvent inlet of the first extraction tank is arranged on the top of the tank body, and the liquid outlet of the first extraction tank is arranged at the bottom of the tank body; the first concentrator includes: a heater 1, the heater 1 is provided with feed port 3, and described heater 1 is any commercially available heater, and the feed port 3 of described heater 1 is arranged at the bottom of heater 1 in the present embodiment, and described first extraction The liquid outlet of the tank communicates with the feed port 3 of the heater 1; the bottom of the heater 1 is provided with a concentrated material outlet 4, and the upper part is ...

Embodiment 2

[0063] The drug extracting device of the present embodiment is based on embodiment 1, such as image 3 As shown, the distance between the vacuum pipe 14 and the outlet 12 of the outlet pipe is 700 m, and the outlet 16 is connected with a drainage pump 17 . Through the drainage pump 17, the condensate in the liquid collector 13 can be discharged in time without destroying the vacuum degree in the drug extraction device, which avoids the adverse effect of the change of the vacuum degree on the operation of the device, saves energy, and simplifies the operation. The efficiency of device operation is improved.

Embodiment 3

[0065] The drug extracting device of the present embodiment is based on the above-mentioned embodiment, such as Figure 4 As shown, it also includes a liquid receiving tank 18, and its shape can be arbitrarily selected according to the actual situation. The liquid receiving tank 18 is arranged below the liquid collector 13. In this embodiment, the bottom of the liquid collector 13 is the receiving tank. The top of the liquid tank 18, the liquid receiving tank 18 is provided with a liquid inlet 19 and a liquid outlet 20, and the liquid discharge port 16 of the liquid collector 13 passes through the liquid inlet 19 and the liquid receiving tank 18 The inside is connected; the distance between the vacuum tube 14 and the outlet pipe outlet 12 becomes 900m. In this embodiment, the bottom of the liquid collector 13 is an inverted cone, and its discharge port 16 is arranged on the inverted cone. At the bottom, the liquid inlet 19 of the liquid receiving tank 18 is arranged on the top...

Abstract

The invention discloses a medicine extraction device. The liquid outlet of a first extraction tank is communicated with the liquid inlet of a first concentrator; and a concentrate outlet of the first concentrator is communicated with a concentrate inlet of an alcohol precipitation tank. The medicine extraction device is characterized in that in a liquid collector of the first concentrator, the position of the outlet of a liquid outlet pipe is lower than and far away from the position of a vacuum pipe in the liquid collector; condensate, flowing outlet from the liquid outlet pipe, directly flows in a liquid accommodating cavity at the bottom of the liquid collector, and then flows in a liquid reception tank for preservation to avoid or reduce the material leakage problem due to leadout of the condensate by a vacuum system; and at the same time, the collected condensate can be directly discharged through a water drainage pump without implementing the device evacuation and the secondary vacuum pumping, so that the operation is easy, the energy consumption is reduced, and the medicine extraction efficiency of the medicine extraction device is improved. Meanwhile, the invention further discloses a technique for extracting medicines by using the device; and the technique is suitable for extracting natural medicines.

Description

technical field [0001] The invention relates to a drug extraction device and a process thereof, belonging to the technical field of pharmaceutical equipment. Background technique [0002] Drug extraction is the process of extracting active pharmaceutical ingredients from natural products such as animals, plants and minerals. Among them, the active pharmaceutical ingredients contained in plants have unique advantages in treating diseases, so the extraction of active pharmaceutical ingredients from plants has attracted much attention. Drug extraction methods include solvent method, distillation method and sublimation method. The latter two methods have narrow applicability and high energy consumption, so they cannot be widely used. Solvent method is often used to extract drugs in industry. [0003] The solvent method is to use the principle of "like dissolves like", according to the properties of the active ingredients of the medicine, select an appropriate solvent to extract ...
