Problems solved by technology

[0003] 2) At present, Gastrodia elata is mainly used as a medicinal material and for people’s daily stewing soup. Because the harvesting period of Gastrodia elata is concentrated and short, and fresh gastrodia elata is extremely perishable, it is not resistant to storage, and it is generally placed at room temperature for 5-7 days; and it must be dried in time after excavation. Dry, so that there is almost no fresh Gastrodia elata supply on the market; processing Gastrodia elata into dry Gastrodia elata, it is very difficult to eat or medicine because of its hard quality, and the dry product loses nutrients and cannot maintain the original gastrodia elata. Taste and flavor, which directly led to the people's consumption of Gastrodia elata
[0004] 3) The low-temperature storage required by the vacuum packaging of fresh Gastrodia elata products currently in use has a short storage time and is extremely perishable; although some sporadic enterprises try to use chemical preservatives for other food preservation in gastrodia elata preservation, but there are still Poor anti-corrosion effect, serious loss of taste, obvious safety hazards and serious environmental pollution and other shortcomings, long-term cumulative consumption may cause other toxic and side effects
