Simple processing method of Gastrodia elata

The processing of Gastrodia elata must first remove the residual stem of Gastrodia elata, pay attention to retain the arrow buds, wash away the sediment, rub off the bacterial cord and scales, rinse with clean water and steam on the drawer. The firepower should be strong, and the drawer cover should be tight, so that it can kill the hemp body cells quickly, inhibit the enzyme activity in the flax body, and prevent serous extravasation. Hemp steamed for 30 minutes, hemp steamed for 15 minutes, to be fully cooked (no white heart) as the degree, if there is excessive flatulence can be punctured with raw needle exhaust, and then put in a hot Kang or drying room, can also be dried. Generally need 4-5 kg fresh Gastrodia elata can process 1 kg finished product.

1. The temperature of the hot Kang should be strictly controlled when it is dried. At the beginning, the firepower should not be too fierce (the best fuel is coal or firewood), so that the Kang temperature can be balanced and kept at 50-60 ℃. After 2-3 hours, the temperature of the Kang gradually rose to 70-80 ℃, so that the water in the hemp body evaporated quickly. If the temperature is too high at the beginning, the outer layer of the hemp body forms a hard shell due to the rapid evaporation of water, and the external dispersion of internal water is blocked, which is not easy to dry for a long time. When the hemp is dry to 7-80%, it should be flattened with a plank, but not too hard to prevent the pulp from running and losing the effect, and then continue to bake on the Kang, at this time the temperature should be 50-60 ℃ to prevent dry coke deterioration (dry Kang). When dry to 8-90%, return to moisture (perspiration) under the Kang, that is, pile it in a low temperature place, cover it strictly with quilts or double-layer gunny bags, and keep the hemp body moist for more than 10 hours, then continue to bake on the Kang until it is fully dry, the Kang temperature is about 50 ℃.

2. Drying in the drying room: put the steamed medicinal Ma Ping in the drying plate (be careful not to overlap), seal the doors and windows, control the temperature at 40-50 ℃ at the beginning, gradually raise the temperature to 70 ℃, and exhaust at the right time according to the change of room temperature and humidity. When drying to 7-8%, flatten, stop exhaust and bake until completely dry.

(1) processing Law of Tongjiang County, Sichuan Province

Wash the commercial hemp with clean water, then rub off the scales with straw or grain husk, put it into a smokeless closed drying Kang while it is wet, bake it with fast water until the hemp is soft (ripe through) without a hard heart, open the seal and continue to bake it with micro-water (40-50 ℃). At the same time, take advantage of the soft flax to pinch the flax body, and when it is too large and inflated, bamboo needles can be used to exhaust. When baking until the hemp body is hard, get back to the Kang (sweating), soften and then enter the Kang, micro-water flood to dry hard, collide with each other to make a crisp sound, and then pile up out of the pit for about a week. If the flax is no longer soft, it is dry and can be boxed and stored.

(2) Hubei Lichuan Fubao processing method

First remove the residual stem of commercial hemp, pay attention to keep the arrow buds, wash away the sediment, scrape off the skin with a thin piece of iron (be careful not to hurt the meat), immediately put it into clear water, add 100 grams of alum in boiling water every 5 kilograms, and gently stir it with wooden piles while boiling water, so that it can be heated evenly, and it is best to boil hemp according to big, medium and small hemp when boiling until it is unintentionally (try to tie it with bamboo needles or look after it in bright places). According to the test, it takes 15-20 minutes for big drugs and 7-9 minutes for small ones. If the maturity is suitable, the drying rate of the finished product can be significantly improved. When cooking hemp, if the expansion is too large, it can be punctured immediately with a bamboo needle and flattened to remove water vapor. The boiled hemp should be immediately removed and cooled in clean water, then removed and dried or dried in the sun. When dry to 8-90%, fumigate once with sulfur balls (add sulfur balls to the charcoal fire, that is, yellow mud 70% Mel 80%, sulfur 30% Mel 20%, add water to form large duck eggs and dry) to make the medicinal materials yellowish white and moth-proof, and dry to the full dry is the finished product.

(3) Hubei meteorite County processing method

Put fine sand or firewood red fire ash into a cauldron, heat and then stir-fry Gastrodia elata. When the hemp is constantly fried, immediately put it into a cold water basin, scrape off the rough skin and scales with a bamboo knife while it is hot, rinse it in alum water, rinse with clean water, steam in the upper drawer for 30-40 minutes, and cook thoroughly. Take out the sun-dried or hot Kang to dry to 6-70%, flatten it with a plank (but not too hard to prevent pulp running), pierce and deflate with a bamboo needle when there are bubbles, and then bake it with charcoal or sulfur until it is completely dry.

(4) in the Hunjiang area of Jilin Province, millet is boiled with Gastrodia elata. When the rice is ripe, Gastrodia elata is removed, the floating foam on the body of Gastrodia elata is floated with clean water, and then placed on a hot Kang to dry.
