Gastrodia must be processed with the digging and harvesting. Because the depositing time is long, Tianma is easy to run the slurry and the dry rate is reduced. Especially Chunma can not be stored. The temperature in spring is high, and if it is not processed in time, it will be mild. During processing, firstly, dig back the Tianma with clean water to wash the soil, then use a cloth to dry the water, and then put it into the pan and stir it together with the fine sand. Depending on the size of the pot (first or second pot), put a small amount of sand in each pot. Depending on the size of the pot (first or second pot), put 4 to 7.5 kg of sand in each pot and place 1.5 to 2.5 kg of gastrodia. According to the size of Gastrodia classification processing. In the processing process, if not according to the size of the classification processing, it will cause some have been fried coke, and some have not fried, affect the finished product volume. During the processing, the fire in the stove should be burned. When the sand in the pot turns red (put in shreds of paper, leaves, etc. immediately catch fire), the gastrodia elata is put into the pot, and it is constantly turned with a shovel. The time is short. Gastrodia flies out of focus, and when it is heard as if it were burned, it sounds louder. When the sound becomes smaller, it is immediately taken out. After that, it is put into a cold water basin that has already been prepared. It is made of small bamboo with a diameter of about 33 cm, and it is split into 4-6. This kind of knife is used to scrape the sharpness of the gastrodia. It is commonly used in the processing of medicinal materials.) The rough skin is gently scraped off, washed and put into the alum. In water, float for about 10 minutes. Then put it in an empty basket, dry it and put it into a sieve. Place it on the sieve. The temperature at the beginning of the crucible is preferably 50-60°C, and after being baked for 2-3 hours, it is raised to 70-80°C. When it is dried to 6/7 dry, it is taken out and squashed by a wooden board. If there is flatulence, it is pierced with a bamboo needle and the air is discharged and then flattened. Finally, it is dried with charcoal and sulfur until it is completely dry, and it is made into translucent milky yellow finished product. The advantage of this processing method is that because the high-temperature processing, only the epidermis of Tianma is scraped off, and the internal marks of the epidermis are still intact and the color is bright. At the same time, it was boiled and the internal medicine components of Tianma were not damaged and the finished product was of high quality, so it was called “Snow Gastrodiaâ€.
