Description

Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine processing, in particular to a preparation system of Phellinus igniarius extract. Background Art

[0002] Phellinus igniarius, also known as mulberry parasite and mulberry herb, belongs to the genus Phellinus in the Polyporaceae family. It has the effects of promoting blood circulation, stopping bleeding, eliminating phlegm, and stopping diarrhea. It also has immune-enhancing, antioxidant, and anti-tumor properties. In the prior art, Phellinus igniarius is often extracted using water. Existing extraction devices often use a leaching pot for direct immersion extraction. Existing leaching pots are often made of materials such as stainless steel. Stainless steel pots have good thermal conductivity and heat up quickly. Rapid heating of stainless steel pots may destroy certain ingredients in the drug, thereby affecting its efficacy. During use, the stainless steel pot may chemically react with certain acidic or alkaline components in Phellinus igniarius, causing the oxide film on the pot surface to be destroyed, thus affecting the pot's service life. It may also cause rust and discoloration on the pot surface. During use, the stainless steel pot easily absorbs substances such as oil and pigments in Phellinus igniarius, causing the pot surface to become greasy and difficult to clean. Existing mulberry linterus extract and mulberry linterus liquid drying devices often adopt a spray drying method. In the spray drying method, an air flow atomizer can be used in the spray drying tower. The air flow atomizers in existing drying methods are directly connected to compressed air. However, for the drying of mulberry linterus extract liquid, this may introduce impurities in the air and reduce the quality of the medicine. Therefore, it is necessary to purify and filter the compressed air of the mulberry linterus extract and mulberry linterus liquid drying device, so as to reduce the impact of a small amount of impurities contained in the compressed air on the drying of the mulberry linterus extract liquid.
