Traditional Chinese Medicine Extract Airflow Grinder

Traditional Chinese Medicine Extract Airflow Grinder

yesSpecialized ultrafine grinding equipment for the pharmaceutical industrySpecially designed for traditional Chinese medicine extract materials with strong viscosity, easy moisture absorption, and heat sensitivity, the dry or semi dry extract can be processed into micrometer sized powders to meet the fineness and efficacy requirements of traditional Chinese medicine preparations such as capsules, granules, and tablets.

Working Principle:

It is achieved by compressing air through freeze-drying and filtering, allowing clean air to enter the crushing chamber at supersonic speed through the crushing nozzle, making the material in a fluidized state. The accelerated material converges at the intersection of several nozzle jet streams, producing intense collisions, friction, and shear to achieve ultrafine particle crushing. The material enters the grading zone with the rising airflow, and due to the high-speed rotation of the grading wheel, the crushed particles are simultaneously subjected to the centrifugal force of the grading wheel and the centripetal force of the fan, achieving the screening effect. Particles that meet the fineness requirements enter the next collection step through the gap of the grading wheel, while particles that do not meet the requirements return to the crushing chamber for further crushing.

1、 Core working principle

2、 Core features of the equipment

1. Adapt to the characteristics of traditional Chinese medicine extract materialsIn response to the problem of high viscosity and easy clumping of traditional Chinese medicine extracts, the device is built-inAnti stick wall device(such as inner wall polishing treatment, inert gas blowing system), to avoid material adhesion to the chamber wall and blockage; By using low-temperature crushing technology, the Joule Thomson effect generated during the expansion of the airflow can reduce the temperature inside the chamber,Protect the thermosensitive active ingredients in the extract(such as volatile oils and alkaloids) are not destroyed.
2. High fineness and uniformityThe particle size of the crushed powder can be1–75μmAdjustable within the range, with narrow particle size distribution and no excessively large or small particles, it can improve the dissolution rate and bioavailability of traditional Chinese medicine powder, meeting the quality requirements of modern Chinese medicine preparations.
3. Compliance and CleanlinessContact with material components using316L stainless steelMaterial, mirror polished inner wall, no corners and easy to clean; supportGMP compliant designIt can be equipped with an online cleaning (CIP) system to meet the clean production standards of the pharmaceutical industry; The crushing process is carried out in a sealed chamber without dust leakage, ensuring the health of operators and the safety of the production environment.
4. Multi functionality and flexibilityswitchableInert gas protection modeSuitable for Chinese herbal extracts containing easily oxidizable components; Support two modes of continuous feeding and batch feeding, suitable for different production scales such as laboratory trials, pilot trials, and industrial mass production; Some models integrate a drying function, which can handle paste materials with high moisture content.

3、 Typical application scenarios

• Suitable for Huangqi extract, ginseng extract, Angelica extract, etcSingle herb extractUltra fine pulverization.

• It can be used for the preparation of compound Chinese medicine extract powder, providing uniform and delicate raw material powder for Chinese medicine compound preparations.

• Equipped with a traditional Chinese medicine extraction production line, achieving an integrated process connection of "extraction concentration drying crushing".

4、 Key points of operation and maintenance

1. Preprocessing requirementsTraditional Chinese medicine extract needs to be dried to a moisture content of ≤ 5% to avoid blockage of the crushing chamber due to high humidity.

2. parameter adjustmentBy adjusting the intake pressure and grading wheel speed, precise control of powder particle size is achieved; Viscous materials can increase the intake flow rate appropriately to enhance the blowing effect.

3. Cleaning and VerificationAfter each material change, it is necessary to clean the crushing chamber and grading wheel at the bottom, and keep a cleaning verification record, which complies with GMP management standards.
