How to perform initial processing of Gastrodia elata

As a fresh-sale product, after the harvest, Tianma must not collide, fail to beat, or cause any mechanical injury. Then, soft brush can be used to gently remove the sand from the hemp body and put it into a soft-lined wooden box or plastic box. Such as processing dry hemp, it takes a long time, generally boiled and cage steaming method of cooking, and then take the drying or drying of the dry method. In the actual production, cage steaming and bake drying methods are generally used to dry them. The operation process is: Gastrodia elata selection - Water wash - Fire steaming - 50 °C 炕 Bake 60 minutes 60 °C 炕 Bake 60 minutes 70 °C 炕 Bake 60 minutes 80 °C 炕 until dry. ?

Selection

According to the weight of gastrodia, the 50-gram difference classification is performed, that is, 50-99 grams, 100-150 grams, 151-200 grams, and more than 201 grams are respectively placed and processed; and unqualified products such as diseased hemp and rotten hemp are discarded at the same time. . ?

Wash with clean water to wash away the sand on the surface of the body. ?

Cage steaming

The washed Tianma steamed into the cage. The general practice is: After the fire is boiled, the largest gastrodin will be placed first. After about five or six minutes of steaming, the second type of gastrodin, which is larger, will continue to be steamed. After the first five minutes, it will be put into the third head. The slightly smaller Tianma is steamed for about five to six minutes. Finally, it is put into small gastrodia and it is generally steamed after five or six minutes of maintaining the fire. ? Steaming process Note: Every time you put a tray of raw hemp, the original cage should be lifted, the new cage is placed in the lowest floor. Examine the degree of ripeness to be ripe, no hard core shall prevail. ?

Bake

Bricks, fire billets, fire burned to 50 °C, the cooked sesame monolayer arrangement, flip once every 30 minutes, increase the temperature every 60 minutes 10 °C, the maximum temperature of 80 °C no longer warm, maintain the temperature until the drying . The main points of the bake-drying process are: When the bake is dry, the bast body is very soft, and the bast body is lightly pressed with a clean and smooth wood board. The purpose is to make it flat and straight, with higher transparency, and easier to use during use. Broken, but also easy to measure; this work can be carried out with the flipping hemp body during the baking process. In addition, in order to increase the value of goods, we can start from three aspects and do a detailed job: First, strict grading. Every time cooked and dried, there is only one size of Gastrodia, which is easy to grasp the heat and operation. Second, after washing the hemp body, the rough appearance, spots, etc. of the gastrodiae are removed using a roller-rolling machine. Thirdly, during the baking process, the hemp body will have subcutaneous bubble protrusions, which can be deflated using very fine bamboo needles, and then pressed and flattened.
