How to carry out the initial processing of Gastrodia elata

When Gastrodia elata is sold or sold, it should be kept free from collision, beating and mechanical scars after harvest, and then the sediment on the flax body should be gently brushed off with a soft brush and packed into soft-lined wooden cases or plastic boxes. Such as processing dry hemp, it takes a long time, generally there are boiling method and cage steaming method for ripening, and then take the way of drying or drying. Cage steaming and Kang drying are generally used in actual production, and the operation process is as follows: Gastrodia elata grade → clean water, → high fire steaming → 50 ℃ Kang for 60 minutes, 60 ℃ Kang baking for 60 minutes, 70 ℃ Kang drying for 60 minutes, 80 ℃ Kang drying until drying.

1. Grade selection. According to the weight of Gastrodia elata, 50 grams of Gastrodia elata were graded, that is, 50-99 grams, 100-150 grams, 151-200 grams and more than 201 grams were placed and treated respectively, and diseased and rotten flax and other unqualified products were removed at the same time.

2. Washing. Wash the sediment off the hemp surface with clean water.

3. Cage steaming. Steam the washed Gastrodia elata in a cage. The general practice is: after boiling the water in a large fire, first put in the largest Gastrodia elata, steam for about 5-6 minutes, then put in the next large Gastrodia elata to continue to steam, 5-6 minutes later, put in the smaller Gastrodia elata, and then steam for about 5-6 minutes. Finally, put in the small Gastrodia elata, maintain the fire for 5-6 minutes, generally all can be steamed. In the process of steaming, attention should be paid to: every time you put a drawer of raw hemp, lift the original drawer and put the new drawer at the bottom. Check the steaming maturity to be thoroughly ripe and without hard core.

4. Kang baking. Brick, billet fire Kang, fire to Kang table 50 ℃, arrange cooked flax monolayer, turn every 30 minutes, raise the temperature by 10 ℃ every 60 minutes, no longer raise temperature when the highest temperature is 80 ℃, and maintain the temperature until drying. The main points of the Kang drying process: when baking to semi-dry, the hemp body is very soft, and the hemp body is gently pressed with clean and smooth wood, in order to make it flat and straight, with higher transparency, easier to break in use, and easy to measure at the same time, the work can be carried out with the overturning of the hemp body in the baking process.

In order to improve the commodity value of Gastrodia elata, we can start from three aspects and do the work in detail: first, strict classification. For each cooking and drying operation, only one specification of Gastrodia elata is used in order to master the heat and operation. Second, after washing the hemp body, use a leather rolling machine to remove the rough appearance and spots of Gastrodia elata. Third, in the baking process, there will be bubbles under the skin of the hemp body, which can be punctured and deflated with a very fine bamboo needle and smoothed and smoothed out.
