Preliminary harvesting and processing technology of Gastrodia elata
Gastrodia elata, such as fresh sales, as long as it does not collide, do not hit, and no mechanical scars 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. If the processing of dry hemp, the method is more complex, generally with water boiling or cage steaming method for ripening, and then drying or sun drying. Cage steaming and Kang drying are generally used in actual production, and the operation process is as follows: grade selection-washing-steaming-Kang drying. 1. The grades are graded according to the weight of Gastrodia elata, that is, less than 50 grams and 50-
