[0002] Lingzhi is a traditional medicinal fungus and a precious Chinese herbal medicine that nourishes and strengthens the body. Lingzhi has the effects of replenishing qi and calming the mind, relieving cough and asthma, and prolonging life. Therefore, it is favored by Chinese people and is widely used in medical care, beauty and other aspects. Some processed products of Lingzhi need to be crushed during production.

[0003] Traditional Ganoderma lucidum crushing equipment mostly uses a single blade rotating or vibrating method for crushing. This method not only has low crushing efficiency, but also due to the fixed movement trajectory of the blade, it is easy to cause uneven crushing, affecting the fineness and uniformity of Ganoderma lucidum powder. In addition, Ganoderma lucidum may carry soil, impurities, etc. during the picking and storage process. If it enters the crushing stage directly without effective cleaning, the purity and quality of Ganoderma lucidum powder will be seriously reduced. Furthermore, the humidity of Ganoderma lucidum also has a significant impact on its crushing effect. Excessive humidity will lead to difficulty in crushing and easy agglomeration, reducing the efficiency of crushing. In response to the above situation, the present application introduces a Ganoderma lucidum crushing device that can be dried. Summary of the invention
