Abstract: A new method for preparing sporoderm-broken ganoderma lucidum spores was put forward in this paper. Based on the theory of impinging streams technology, supercritical fluid was used as working fluid in this method, so the impinging streams technology can be used in the hyper high pressure field. Combined with the properties of supercritical fluid technology, a new concept, hyper high pressure supercritical impinging streams technology, was given in this paper. A test system using this method to prepare sporoderm-broken ganoderma lucidum spores was made. This method is proven to be efficient and easy operated. Purity of products made by this method is high. Initial researches show that the sporoderm-broken ratio is 75%.
