A Brief Discussion on Low Oxygen Maintenance System for Traditional Chinese Medicine

　　The low oxygen controlled atmosphere maintenance system for traditional Chinese medicine is a new technological means that protects and preserves Chinese medicine materials by reducing the oxygen concentration in the storage space. The main advantages of this technology are that it can effectively extend the shelf life of medicinal materials, reduce water loss, slow down the oxidation rate of medicinal materials, prevent mold growth, and minimize the loss of other bioactive substances. In addition, the use of this technology can also increase the content of effective ingredients in traditional Chinese medicine, thereby enhancing drug efficacy. The operating principle of the system is to adjust the proportion of air components in a closed space, so that the oxygen content in the environment can be reduced to a certain range. This can inhibit the growth and reproduction of microorganisms, delay the decomposition process of active ingredients in drugs, and achieve the purpose of maintaining traditional Chinese medicine.

　　Function and purpose

　　function

　　Insecticidal, antifungal, insect infested, moldy, fresh-keeping, oxidation discoloration, oil stripping, sugar bleeding, and stubble changing

　　Purpose

　　1. The parameters such as relative humidity and oxygen content in each storage cabinet can be adjusted and displayed to achieve the purpose of preventing insect infestation, mold growth, aflatoxin, moisture absorption, and maintaining the characteristics of Chinese medicinal materials and decoction pieces; The available storage space should be sufficient to store more specimens. The storage cabinet door should be made of color changing glass and can be switched between transparent (display) and opaque (storage) to achieve the purpose of freely switching between storage and display functions.

　　2. The main material is carbon steel sprayed, and the glass door is made of color changing glass, which can be converted between transparent (display) and opaque (storage). The net volume of a single storage cabinet is not less than 3m3, 5m3, 10m3, 15m3, 20m3, 30m3

　　3. Require storage cabinets in the warehouse to have good air tightness and a ventilation rate of no more than ≤ 0.02d-1

　　We have briefly introduced the low oxygen regulation and maintenance system for traditional Chinese medicine here. It should be noted that the construction and operation of this system require professional technical personnel to manage and operate it. Only by strictly following the correct operating procedures can the advantages of this system be fully utilized. Therefore, in the actual application process, it is also necessary to pay attention to strengthening management measures to ensure that the system is effectively applied.
