The invention relates to a method for processing a dendrobium huoshanense plant dry product. The method comprises the following process steps of: harvesting, picking, putting, fixing shapes, freezing quickly at ultralow temperature, dehydrating and drying under vacuum, sealing and packaging, namely selecting dendrobium huoshanense plants which are healthy and strong in growth and have the growth time of 2 to 5 years and the plant height of between 1 and 11 centimeters, picking the plants, washing, and fixing the shapes in a die; when the temperature of a freeze drying chamber is reduced to -80 DEG C, putting the die into the freeze drying chamber, freezing quickly, and reducing air pressure in the freeze drying chamber; heating gradually, drying under the vacuum for 34.5 hours until the pressure reaches to 10 pa, maintaining for 13 hours and halting; and weighing the dendrobium huoshanense plants, vacuumizing and packaging. In the method, in the process from drying to packaging of thedendrobium huoshanense plants, the original forms of the dendrobium huoshanense plants are kept, and the risk of counterfeiting the dendrobium huoshanense plants is reduced, so the reliability and cognition degree of products can be improved; and in the processing method, processing processes such as crushing and the like are avoided, so active ingredients and nutrient substances in raw materialsare ensured.
