Medicine extraction device and technique thereof

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 ...

AI Technical Summary

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 used in the above-mentioned drug extraction device needs to adjust the vacuum communication valve and the vacuum bypass valve before and after each discharge of the condensate (solvent), so as to empty and reset the lower part of the liquid receiving tank. Vacuuming is not only cumbersome to operate, but also increases energy consumption, which reduces the concentration efficiency of the device
