Description

Technical Field

[0001] The invention relates to the field of Chinese patent medicine sterilization, and in particular to a Chinese patent medicine storage tank sterilization process and equipment. Background Art

[0002] Chinese patent medicines are made from Chinese medicinal materials, and are processed into certain dosage forms according to prescribed prescriptions and preparation processes under the guidance of traditional Chinese medicine theory for the purpose of preventing and treating diseases. Therefore, as Chinese patent medicines for clinical application, they must not only have corresponding drug names, usage and dosage, specifications, specific quality standards and inspection methods, but also have definite therapeutic effects, clear scope of application, application contraindications and precautions.

[0003] Steam sterilization equipment is usually used to sterilize medical devices and food tableware. While effectively achieving the purpose of sterilization, it must be heated for a long time. Steam-type Chinese patent medicine sterilization cabinet is suitable for the sterilization of Chinese medicine, cereals, tea and other powders. However, after the above-mentioned long sterilization treatment, it is very easy to cause changes in the color, aroma and active ingredients of the treated products, affecting the quality and value of the products, and there will also be safety hazards.

[0004] Chinese Patent Publication No.: CN1135721A discloses a sterilization method and sterilization device, which uses heated water vapor or superheated water vapor to instantly heat and pressurize the inside of a closed structure sterilization container with raw materials added, then releases the pressurized state and immediately and rapidly reduces the pressure to a vacuum state; thereafter, the sterilized raw materials are continuously moved into a vacuum cooling dryer with a closed structure, and vacuum cooled and dried to obtain the desired sterilized product. In this prior art, it uses high-pressure superheated steam for instant sterilization, which effectively saves the time of heating sterilization, thereby ensuring the quality of the raw materials.

[0005] In the above scheme, before the raw materials are heated and sterilized with high-pressure superheated steam, the closed sterilization container containing the raw materials to be heated to high temperature is not preheated in advance, and the high-pressure superheated steam is directly passed through the closed sterilization container containing the raw materials. In this way, when the high-pressure superheated steam encounters the closed sterilization container with a lower temperature, it is easy for the steam temperature to drop sharply and condense, thereby causing the raw materials to become damp and agglomerate, affecting the properties of the product.

[0006] Chinese Patent Publication No.: CN212913977U discloses an ethanol gas pressure steam sterilizer, including a shell, a sterilization chamber is arranged inside the shell, a sandwich is arranged between the sterilization chamber and the shell, an inner chamber air inlet is arranged between the sandwich and the sterilization chamber, a heater is arranged on one side of the sandwich, an air inlet pipe and an air outlet pipe are arranged on both sides of the heater, the other end of the air outlet pipe is connected to the sandwich, a vacuum pump is arranged on one side of the sterilization chamber, the other end of the air extraction pipe on the vacuum pump is located inside the sterilization chamber, and an ethanol vaporizer is connected to one side of the sterilization chamber. Compared with the prior art, saturated steam is used for indirect heating in the sandwich, and ethanol gas is used to sterilize most Chinese medicinal materials under the condition of vacuum degree ≥0.07Mpa, so as to ensure that the Chinese patent medicine containing crude drug powder meets the specified hygiene standards. The pressure steam sterilization pipeline is designed to facilitate the sterilization of some medicinal materials that can be sterilized by steam.

[0007] The ethanol gas sterilization method in this scheme adds ethanol gas after vacuum, so when the pressure is gradually restored, condensation is likely to occur. The condensed water vapor will be mixed in the Chinese patent medicine, causing the powdered Chinese patent medicine to agglomerate; The pressure steam sterilization method in this scheme opens the exhaust valve to exhaust after sterilization is completed, and then vacuum dries after the exhaust is completed. In this process, the steam that cannot be discharged quickly will also affect the powdered Chinese patent medicine, and after drying, the damp Chinese patent medicine will become hard lumps, affecting sales.

[0041] The water tank 501 is driven by the control panel, and a small water flow can be gradually introduced into the evaporation chamber A503, thereby improving the efficiency of steam generation. A one-way valve is also provided inside to ensure the pressure of steam generation.

[0042] The ethanol gas generator 6 includes an ethanol tank 601, a dripping pipe B602, an evaporation chamber B603 and an air supply pipe B604.

Water vapor can be condensed in the condenser 1003 and replenished in the water tank 501. Ethanol vapor can also be condensed and recovered in the same way. If the water vapor pressure is too high to be recovered in time, the pressure valve on the condenser 1003 can still discharge water vapor to the outside. However, ethanol vapor is not used for direct discharge to the external environment. When it is actually used in the workshop, an exhaust gas access pipe must be installed.
