How to carry out the initial processing of Gastrodia elata

As a fresh sale, Gastrodia elata should maintain no collision, no beating, no mechanical scars and so on after harvest, then gently brush off the sediment from the flax body with a soft brush and load it into a soft-lined wooden box or plastic box. Such as processing dry hemp, it takes a long time, generally there are water boiling method and cage steaming method for ripening, and then take the way of drying or sun drying. Cage steaming and Kang drying are generally used in actual production, and the operation process is as follows: Gastrodia elata selection-washing with clean water-steaming over high fire-50 ℃ Kang drying for 60 minutes 60 ℃ Kang drying 60 minutes 70 ℃ Kang drying 60 minutes 80 ℃ Kang drying until drying.

Selection of grades

According to the weight of Gastrodia elata, 50 grams of Gastrodia elata were graded, that is, 50 grams, 100 grams, 150 grams, 151 grams, 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.

Wash the surface sediment of the hemp body with clean water.

Cage steaming

Steam the washed Gastrodia elata in a cage. The general practice is: after the fire is boiled, first put in the largest Gastrodia elata, steam for about five or six minutes, then add the second larger Gastrodia elata to continue steaming, five or six minutes later, put in the third smaller Gastrodia elata, then steam for about five or six minutes, finally put in the small Gastrodia elata, maintain the fire for five or six minutes, generally all can be steamed. Note in the steaming process: each time you put a drawer of raw hemp, lift the original drawer and place the new drawer at the bottom. Check the steaming maturity to be thoroughly ripe and without hard core.

Kang baking

Brick and billet hot Kang, burn to the Kang table for 50 ℃, arrange the cooked sesame seeds in a single layer every 30 minutes, raise the temperature by 10 ℃ every 60 minutes, do not rise again 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 flax body is gently pressed with clean and smooth wood, in order to make it flat and straight, with higher transparency, and easier to break in use, but also easy to measure; the work can be carried out with the overturning of the hemp body in the baking process. In addition, in order to improve the value of goods, we can start from three aspects and do the work in detail: first, strict classification. Each cooking and drying operation, there is only one specification of Gastrodia elata, which is easy 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, the hemp body will have subcutaneous bubbles, which can be punctured and deflated with a very fine bamboo needle, and then smoothed and smoothed.
