Talking about the Effective Process and Equipment Scheme of Gastrodia elata Dryer

The processing steps of Gastrodia elata are as follows: graded screening of Gastrodia elata & mdash; & mdash; cleaning & mdash; & mdash; cooking & mdash; & mdash; drying & mdash with heat pump Gastrodia elata dryer dryer; & mdash; & mdash; finished product packaging. Gastrodia elata should be kept free of collision, beating and scars after harvesting, and then gently brush the sediment off the hemp body with a soft brush. Generally, there are water boiling and cage steaming methods for cooking. Here, the application of drying equipment of Gastrodia elata is emphasized.

p>Gastrodia elata was packed in tubers with initial moisture content of 70-85%, and had the characteristics of stickiness, heat sensitivity and polysaccharide. Therefore, in the drying process of Gastrodia elata dryer , attention should be paid to dehumidification and sweating. The following four key drying steps are summarized as follows:

The first stage is mainly dehumidification, drying temperature is about 35-55 C, and drying time is about 15-20 hours. The first sweating of Gastrodia elata should be carried out after completion.

the second stage: the drying temperature is about 30-45 and the drying time is about 8-10 hours. The second sweating of Gastrodia elata was completed. The third stage of

is still mainly dehumidification. The drying temperature is set at 30-40 (?) C and the drying time is about 8-12 hours. Gastrodia elata was dried and sweated for the third time.

Stage 4: In the drying stage, the temperature is set at about 35 C, with less dehumidification and mild drying, so as to avoid sugar decomposition, deterioration, blistering, and the final moisture content of Gastrodia elata is less than 10%. Although the drying period is longer, the color of Gastrodia elata is bright, the meat is thick, and the effective ingredients of gastrodin are best preserved. The operation process of

Gastrodia elata dryer should pay attention to that the drying temperature and humidity parameters of different varieties and heads of Gastrodia elata need to be moderately adjusted, and in the drying process, there will be bubbles protruding under the skin of the hemp body, which can be punctured and deflated with very fine bamboo needles, and then smoothed and smoothed. In addition, Gastrodia elata is rich in polysaccharides and other nutrients, easy to mildew and live insects, so if the dried Gastrodia elata is not sold immediately, it should be tightly sealed with double-layer thickened plastic bags in time, then placed in cartons or wooden boxes, and stored in light, ventilation, cool, rodent-free places. Meiyu season should also be checked regularly, found problems, timely take out for drying, or do other corresponding treatment.
