The correct method of cold storage for medicinal materials

The correct method of cold storage for medicinal materials mainly includes the following aspects to ensure that the quality and efficacy of medicinal materials are maintained:

1. Temperature control

The optimal storage temperature of medicinal materials is between 0℃-5℃. For specific medicinal materials such as angelica, it is recommended to store them at around 5℃.

It should be noted that too low temperature may cause the medicinal materials to melt or absorb moisture, while too high temperature may cause the medicinal materials to lose crystal water or weathering. Therefore, the use of intelligent temperature control system is very critical for precise temperature control.

2. Humidity control

The storage humidity of Chinese medicinal materials is generally controlled at around 50%, which can maintain the nutrients of Chinese medicinal materials and prevent them from over-drying. However, there are also opinions that suggest that the humidity should be controlled between 60%-70%.

The use of dehumidification devices can keep the humidity in the warehouse within a suitable range to prevent the medicinal materials from getting damp and deteriorating.

3. Light control

Chinese herbal medicines are prone to deterioration under direct sunlight, so special attention should be paid to light control when stored in cold storage. It is recommended to use a dark room or reduce the light exposure time to reduce the impact of light.

4. Air control

Oxygen, moisture and debris in the air will affect the preservation of Chinese herbal medicines. In cold storage, it is necessary to clean the air purification device regularly, ensure air circulation and reduce the number of in and out times.

5. Other precautions

Before putting the medicinal materials into the cold storage, check whether the packaging is intact and undamaged, whether there is moisture and agglomeration, etc.

Different medicinal materials should be stored separately to avoid mutual influence between the medicinal properties of the medicinal materials. At the same time, for medicinal materials that require special treatment, such as precious tonics, appropriate storage methods such as insect prevention should be adopted.

To prevent food from tainting other items, you can use plastic wrap to wrap them and then send them to the cold storage for storage.

The rubber strips on the cold storage door should be scrubbed frequently to prevent grease from clogging the passage.

In summary, the correct method of storing medicinal materials in cold storage involves the control of temperature, humidity, light, air and other aspects, as well as the handling of details such as packaging and storage. Only by comprehensively considering these factors can we ensure that medicinal materials are properly stored in cold storage to maintain their quality and efficacy.
