Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine processing technology, specifically a process for breaking down the cell walls of Ganoderma lucidum spores to produce powder. Background Technology

[0002] Ganoderma spores are oval reproductive cells ejected from the gills of Ganoderma during its growth and maturation period. They have a particle size of 4-6 micrometers and are living organisms with a double-walled structure. They are surrounded by chitinous cellulose, making them difficult for the human body to fully absorb. After the cell wall is broken, they are more suitable for direct absorption by the human gastrointestinal tract. The content of Ganoderma triterpenoids in spore powder is extremely low, and the content of triterpenic acids is at the ppm level.

[0003] Chinese invention patent CN113210105B, published on March 29, 2022, discloses a process for breaking the cell wall of Ganoderma lucidum spore powder, including the following steps: S1, take dried Ganoderma lucidum spores, pulverize them into Ganoderma lucidum spore powder in an ultra-micro pulverizer, then put them into a sealed container, humidify them by passing saturated water vapor through them at room temperature, and then let them stand at -15-20℃ for 5-6 hours before pulverizing them into 1-1.5μm powder; S2, place the material obtained in step S1 into an air jet mill, then add ceramic powder, and pulverize it by air jet milling at 2-5℃ to obtain a mixture of broken cell wall Ganoderma lucidum spore powder; S3, pass the mixture of broken cell wall Ganoderma lucidum spore powder obtained in step S2 into a separation device for separation, and collect the broken cell wall Ganoderma lucidum spore powder and the spore wall mixture separately; S4, dry the collected broken cell wall Ganoderma lucidum spore powder to obtain the finished product. The Ganoderma lucidum spore powder cell wall breaking process provided by this invention can not only effectively improve the cell wall breaking rate and effective ingredient content of Ganoderma lucidum spore powder, but also ensure the antioxidant effect while being waterproof, thereby effectively extending the shelf life.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: The cell-wall breaking process of this application uses an airflow pulverizer to break the cell walls, which results in low cell-wall breaking efficiency and cannot meet the cell-wall breaking needs of large-scale production of Ganoderma lucidum spore powder. In addition, the overall process is prone to contamination during the transfer of multiple devices. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems and provide a process for breaking down the cell walls of Ganoderma lucidum spores to produce powder.

[0006] To achieve the above objectives, the present invention employs the following technical solutions;

[0007] The technical solution adopted by this invention to solve its technical problem is: a Ganoderma lucidum spore powder cell wall breaking and powdering process described in this invention, which includes the following steps:

[0008] S1: Select Ganoderma lucidum spore powder raw materials, filter out impurities and unqualified Ganoderma lucidum spore powder, separate qualified Ganoderma lucidum spore powder, and perform low-temperature vacuum drying to obtain dried Ganoderma lucidum spore powder;

[0009] S2: The dried Ganoderma lucidum spore powder is sealed and transported to a dry ice freezing chamber. It is kept at a constant temperature for 30–45 minutes in a low-temperature environment, so that the spore wall changes from tough to brittle, creating a structural basis for subsequent physical wall breaking.

[0010] S3: A mixture of liquid carbon dioxide is fed into the running ball mill along with high-pressure air, and the ball mill physically breaks down the cell walls of the frozen Ganoderma lucidum spore powder.

[0011] S4: Collect the Ganoderma lucidum spore powder after cell wall breaking, and filter and screen out the Ganoderma lucidum spore powder that has not been broken.

[0012] S5: After sieving, the cell-wall broken powder undergoes low-temperature dehumidification in a nitrogen-protected fluidized bed dryer, and simultaneously undergoes antioxidant encapsulation treatment to prevent the oxidative deactivation of polysaccharides and triterpenes.

[0013] Furthermore, in step S1, the filtration for cleaning the Ganoderma lucidum spore powder is performed using air separation.

[0014] Furthermore, the moisture content of the Ganoderma lucidum spore powder in S1 is less than or equal to five percent.

[0015] The present invention provides a cell wall breaking and powdering process for Ganoderma lucidum spore powder, which has the following beneficial effects:

[0016] 1. This invention first freezes and cools the Ganoderma lucidum spore powder, causing the spore wall to change from tough to brittle. Then, it is carried away by a high-speed airflow and impacts the inner wall and grinding balls of the ball mill to break the spore wall. The spore wall is then broken by further impacts in the ball mill. This results in a better spore wall breaking effect and a higher success rate compared to using the ball mill directly. It also reduces the operating temperature of the ball mill and maintains the activity of the Ganoderma lucidum spore powder components. Attached Figure Description

[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings;

[0022] Please see Figure 1 As shown, a process for preparing Ganoderma lucidum spore powder by cell wall breaking includes the following steps:

[0023] S1: Select Ganoderma lucidum spore powder raw materials, filter out impurities and unqualified Ganoderma lucidum spore powder, separate qualified Ganoderma lucidum spore powder, and perform low-temperature vacuum drying to obtain dried Ganoderma lucidum spore powder;

[0024] S2: The dried Ganoderma lucidum spore powder is sealed and transported to a dry ice freezing chamber. It is kept at a constant temperature for 30–45 minutes in a low-temperature environment, so that the spore wall changes from tough to brittle, creating a structural basis for subsequent physical wall breaking.

[0025] S3: A mixture of liquid carbon dioxide is fed into the running ball mill along with high-pressure air, and the ball mill physically breaks down the cell walls of the frozen Ganoderma lucidum spore powder.

[0026] S4: Collect the Ganoderma lucidum spore powder after cell wall breaking, and filter and screen out the Ganoderma lucidum spore powder that has not been broken.

[0027] S5: After sieving, the cell-wall broken powder undergoes low-temperature dehumidification in a nitrogen-protected fluidized bed dryer, and simultaneously undergoes antioxidant encapsulation treatment to prevent the oxidative deactivation of polysaccharides and triterpenes.

[0028] In S1, the filtration process for cleaning Ganoderma lucidum spore powder uses air separation, which ensures that no new contaminants are introduced during the screening process, thus guaranteeing the cleanliness of the Ganoderma lucidum spore powder.

[0029] The moisture content of Ganoderma lucidum spore powder in S1 is less than or equal to 5%. Keep it dry to extend its shelf life.

[0030] Impurities in S1 include mycelium, dust particles, and shriveled spores. Removing these ineffective impurities ensures product quality.

[0031] After cell wall breaking in S4, the material is filtered through an airflow sieve using a 120-mesh standard sieve, ensuring consistent filtration standards and stable product quality.

[0032] The target temperature for low-temperature dehumidification in the S5 is ≤35℃, and the humidity is ≤3%, which allows for long-term storage and extends its service life.

[0033] During the low-temperature dehumidification process in S5, natural vitamin E microcapsules are added to Ganoderma lucidum spore powder to prevent the oxidative inactivation of polysaccharides and triterpenes.
