Abstract

The invention relates to an ozone sterilization device for a traditional Chinese medicine solid preparation / raw powder. The ozone sterilization device comprises an ozone generator and a sterilization device, wherein the sterilization device comprises an oilless vacuum pump, a sterilization tank, an ozone tail gas processor, an electric valve and a connecting pipeline between the parts, the sterilization tank comprises a hollow tank body, an upper grading shield and a lower grading shield, as well as emitting heads of ultrasonic generators which are uniformly distributed at the periphery of the hollow tank body, five cross pipes are arranged in the connecting pipeline, a gas inlet and outlet sharing port and an exhaust port are formed in the upper grading shield, a gas inlet port and an exhaust port are formed in the lower grading shield, a filter net plate or a filter net support plate is arranged at the bottom of the hollow tank body, the upper grading shield and the lower grading shield are respectively in sealing butt joint with the upper end and the lower end of the hollow tank body through connecting flange plates, and a sealing ring is arranged between the connecting flange plates.

Description

technical field [0001] The present invention relates to a kind of sterilization equipment of Chinese medicine solid preparation / raw material powder, especially a kind of equipment which uses ozone to sterilize Chinese medicine solid preparation / raw material powder. The ozone sterilizing device penetrates into each Chinese medicine solid preparation / raw material powder and guarantees no dead angle for sterilization. Background technique [0002] Traditional Chinese medicine is the most national characteristic of our country. In its application, it often has unique advantages that cannot be replaced by western medicine. It has long been trusted by patients with chronic diseases, especially for some difficult and miscellaneous diseases. It often has a medical effect that western medicine can't expect At present, a large number of traditional Chinese medicine solid preparations (i.e. Chinese patent medicine tablets and granules) and raw material powders (i.e. traditional Chinese...

Problems solved by technology

[0003]Aiming at how to sterilize solid preparations of traditional Chinese medicine and raw material powder of traditional Chinese medicine, the Ministry of Health of my country distributed 60 Co irradiated traditional Chinese medicine sterilization dose standard, which has strict regulations on how to grasp the 60Co source, equipment standards and dosage during the sterilization process of traditional Chinese medicine solid preparations and traditional Chinese medicine raw material powder. This kind of sterilization measures as a last resort is often accompanied by secondary pollution in actual operation.

[0004] Patent Document No. CN101380479A discloses a multi-tower ozone sterilization system for powder materials. It is effective to sterilize Chinese medicine powder in terms of its principle. However, its system structure is relatively complicated. Since the suspended powder needs to be switched between at least two towers, the pipeline is relatively complicated. Long, once the suspended powder is deposited on the pipe wall, it is difficult to clean up. For a single type of powder, this deposition has no effect. For the series of traditional Chinese medicine powder products that need to be changed frequently, this deposition will inevitably change the quality of the traditional Chinese medicine powder. The purity of the series of products affects the quality of the series of traditional Chinese medicine powder products. For solid preparations of traditional Chinese medicine that cannot be suspended, they cannot be operated in a multi-tower ozone sterilization system for powder materials.

[0005] In response to the above problems, the applicant submitted an application for an invention patent entitled "Ozone Sterilization Device for Traditional Chinese Medicine Solid Preparation / Raw Material Powder", whose publication number is CN102940896A , we found that since the directions of vacuuming and ozone pressurization of the ozone sterilizer are irreversible, during a sterilization process, they always squeeze the medicine multiple times along one movement direction, which is very easy Hardening, affecting the inactivation effect of ozone
