This paper takes fresh gastrodia elata of Xiaocaoba as the research object. After the samples are steamed, two processing methods which are hot air drying and heat pump drying are used respectively. The drying temperature is set at 50 degrees for both methods. The results show that different weight gastrodia elata is suitable for different drying methods. The gastrodia elata of 70-105 grams is suitable dried by the hot air drying, while the gastrodia elata of 105-140 grams is better dried by the hot pump drying. The two drying methods had no effect on polysaccharides of samples.
