Description

Technical Field

[0001] This utility model belongs to the technical field of yarrow dehydration and blanching equipment, specifically relating to a semi-automatic tea-frying device for yarrow tea. Background Technology

[0002] Yarrow is a plant belonging to the genus *Achillea* in the family Asteraceae. *Achillea* is a perennial herb with alternate, pinnately lobed, serrated leaves. It has many heteromorphic flowers arranged in corymbose inflorescences, with an oblong, ovate, or hemispherical involucre. The earliest Chinese record of yarrow fruit is found in the *Shennong Bencao Jing* (Shennong's Classic of Materia Medica): "Yarrow fruit, bitter in taste, neutral in nature. It primarily benefits qi, nourishes the skin, brightens the eyes, enhances intelligence, and improves foresight. Long-term use prevents hunger, aging, and lightness of body. It grows in mountain valleys." Yarrow is often used as a seasoning, food preservative, and as a substitute for cinnamon or nutmeg. It is also used as hops in beer brewing, in medicinal wines and teas. However, due to the structural characteristics of yarrow itself, it is not easy to preserve and transport it for a long time if it is directly packaged after harvesting. Therefore, after harvesting, yarrow needs to be dehydrated and blanched. However, traditional tea dehydration and frying equipment is not good at fully dehydrating the serrations and inflorescences of yarrow, which affects its shelf life. Summary of the Invention
