2. Spread the air method. This method is also called the dry method. The medicine is placed in the shade of the room or in the greenhouse, and the flowing air is used to blow off the water to achieve the purpose of drying. This method is often used in rainy weather, or for medicinal materials containing volatile oils and medicinal materials that are easy to remove oil and discolor, such as jujube, beryl kernel, anemarrhena, bitter almond, codonopsis, aspartame, and hemp seed.
3. Drying method. This method is a traditional, simple and economical method of drying herbs. Applying this method requires one or several rectangular fires in the room or in the greenhouse. The length of the fire is about 1.5m. The length can be determined according to the amount of the medicine. A small door that can be switched is placed every 80cm below the fire to add fuel. After that, place a stove in it, and place an iron plate at the fire mouth of the stove to raise the fireproof seedlings, roast the medicinal materials, and disperse the heat. When the barrier is 1.2 to 1.5 m high, a circular steel pipe with a diameter of 3 to 4 cm is placed horizontally every 60 cm. A wire mesh is placed on the steel pipe, and the mesh is covered with mud, and then the fire is increased by 60 cm. . Ignite the stove, dry the fire and covered mud, and place the medicinal material in the gutter in the small and small layer. But don't pretend it to be too full, 30~40cm thick, covered with sacks, straw curtains, etc. When a large amount of steam rises, it is necessary to open the sack or straw curtain in time, and pay attention to turning the medicine up and down until it is dried. This method is applicable to the drying of medicinal materials such as Chuanxiong, Alisma, and Platycodon grandiflorum. In the drying process, it is necessary to pay attention to the heat, so as not to scorch the medicinal materials, and to master the degree of dryness according to the special requirements of different medicinal materials.
4. Drying room and dryer drying method. The method is suitable for use in large-scale medicinal planting bases, with high efficiency, labor saving, cost saving, free from weather restrictions, and can also play the role of insecticide and mildew proof, temperature controllable, suitable for all kinds of medicinal materials, without affecting The quality of medicinal materials is a more advanced drying method. However, it is necessary to pay attention to the construction of the drying room according to the technical requirements and standards of the standard and purchase special drying machinery, which is operated by professionals familiar with the drying technology. Also pay attention to control the drying temperature and time according to the different properties of the medicine.
5. Far infrared heating and drying method. This is a new drying technology. The drying principle is to convert electric energy into far-infrared radiation, which is absorbed by the molecules of the medicinal materials, causing resonance, causing vibration and rotation of molecules and atoms, causing the objects to heat up, through thermal diffusion and evaporation. And chemical changes, zui finally achieve the purpose of drying. Seeds and rice medicinal materials can be dried by this method. Far-infrared drying can save 20% to 50% of electricity, and the effect is better.
6. Microwave drying method. Microwave drying is actually through the induction heating and medium heating, so that the moisture and fat in the Chinese herbal medicine absorb microwave energy to different degrees, and convert it into heat to achieve the purpose of drying. Microwave drying can kill microorganisms and molds, and has a disinfecting effect, so that the medicinal materials can meet the hygienic standards, and can prevent mold and insects during the storage process. At present, the microwave heating equipment produced in China has two frequencies of 915MHz and 2450MHz.
Several drying methods commonly used in Chinese herbal medicines
1. Selenium method. This is a drying method commonly used in most medicines. Choose sunny, windy weather, spread the herbs on the banquet or on the concrete floor, use the sun to dry, pay attention to turn in time to ensure even sunlight. When drying in the autumn, due to the high humidity at night, it is necessary to pay attention to the medicine and close it to prevent moisture.
