The production technology of Chinese medicinal materials is relatively backward, and the planting methods are relatively primitive. The main problem is the lack of Chinese medicinal materials production and management standards. The development and utilization of authentic medicinal materials is not sufficient, the cultivation of Dalai medicinal materials lacks strict procedures, and the low yield and poor quality surplus of production management are more common. Especially in the process of drying and processing of medicinal materials, the use of coal-fired drying or sulfur fumigation and other primitive processing methods have caused the medicinal materials to be contaminated and the sulfur content exceeds the standard.

Factors affecting the drying of Chinese herbal medicines

1. Types and properties of Chinese medicinal materials-Chinese medicinal materials also include roots, stems, leaves, fruits, seeds, skins, etc. The shape, size, thickness, weight, texture, composition and other factors of Chinese medicinal materials all affect the drying process.

2. Drying temperature...·According to the different physical disciplines, in the case of ensuring the drying quality, try to choose a high drying temperature. To speed up the drying speed.

3. The content of different humidity in the humidity material

4. The wind speed of the hot air medium The speed of the hot air medium in the drying chamber is related to the drying speed, the form of the material, and the characteristics of the material.

5. Selection of drying speed and drying method... Dry explosion should be controlled under certain technical parameters such as temperature, humidity and wind speed. In order to ensure the preservation of the pharmacological ingredients of the material during the drying process.

6. Material placement method-stacking thickness, the placement method affects the drying speed. The accumulation thickness should be reasonably controlled, and the heat exchange area and ventilation rate should be increased to speed up the drying speed.

7. Mixed drying of different varieties... In principle, a single variety is required when drying Chinese medicinal materials, and multiple varieties cannot be mixed together for drying.

8. Secondary drying. Generally refers to the secondary drying of the stored raw materials that have been dried before the Chinese medicinal materials are processed.

The Nesda high temperature dryer is suitable for use in an environment with a temperature of 65°C. It solves the technical requirements for high temperature drying of Chinese medicinal materials and speeds up the drying speed of Chinese medicinal materials. The temperature, humidity, and time can be set according to different medicinal materials to ensure Chinese medicinal materials Drying reaches a favorable moisture content, fully automatic control, no need to manually turn, to prevent pollution problems, environmental protection and energy saving, simple operation, high efficiency, fast drying time, more Nysda high-temperature dryer product applications, please contact Nysda Make contact.
