Overview
The storage system for low oxygen and dense controlled atmosphere maintenance products of traditional Chinese medicine uses high-purity equipment to produce nitrogen gas, which quickly reduces oxygen content to 1% in a very short period of time. To achieve pest suffocation, inhibit mold, prevent oxidation and deterioration of effective ingredients in medicinal materials, control the moisture content of medicinal materials, ensure constant temperature and humidity in the storage environment, and prevent mold growth. It can also achieve rodent proof, fire-resistant, and anaerobic storage of large quantities of medicinal materials. It is considered a scientific maintenance method that effectively solves the storage problems of insect infestation, mold growth, oxidation discoloration, oil leakage, sugar bleeding, and stubble change that often occur in traditional Chinese medicine materials. It maintains the good appearance and internal quality of traditional Chinese medicine materials, reduces natural losses during storage, and lowers the overall cost of warehouse maintenance. At the same time, Dachang's low oxygen regulation technology is used to achieve traceability of traditional Chinese medicinal materials.
function
Insecticidal, antifungal, insect infested, moldy, fresh-keeping, oxidation discoloration, oil loss, sugar bleeding, and stubble growth.
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
4. Adopting the method of atmospheric pressure and low oxygen nitrogen filling, the pressure inside the cabinet should be controlled within atmospheric pressure ± 200Pa (gauge pressure) to avoid damage to the storage of Chinese medicinal materials, Chinese herbal decoction pieces, and storage cabinets. The purity of nitrogen gas should not be less than 99.0%.
5. It is required to use multi-stage composite pressure filtration technology and hollow fiber membrane nitrogen oxygen separation technology, with a filtration accuracy of no more than 0.01 μ m, effectively filtering out oxygen, harmful gases, dust particles, mold spores, insect eggs, etc. in the air.
6. The concentration of inorganic gaseous pollutants under low oxygen conditions should meet the following requirements and provide a third-party gas quality testing report: sulfur dioxide<10 μ g/m3. nitrogen dioxide<10 μ g/m3. ozone<24.5 μ g/m3. chlorine gas<10 μ g/m3. hydrogen chloride<4.5 μ g/m3
7. The range of oxygen content regulation in the storage cabinet is 1%~21%, and the accuracy of oxygen content regulation is ± 0.5%.
8. Replacement time for a single storage cabinet: It takes no more than 3 hours for the oxygen concentration to decrease from 21% to 5%, and no more than 3 hours for the oxygen concentration to decrease from 5% to 2%.
9. The relative humidity control range is 10%~65% RH (20 ℃), the humidity control accuracy is within ± 3% RH range, and the humidity fluctuation is within 5% RH range.
10. Temperature regulation range: -20 ℃ to room temperature (optional).
functional indicators
1. The system equipment has a one click "start/stop" automatic operation.
2. The system equipment has independent automatic detection, setting, and display of parameters such as oxygen content and humidity in each storage cabinet.
3. Remote control function: The on-site equipment can be operated through the mobile APP software (in any area of the network), and the parameter screen is consistent with the touch screen. Optional
