Traditional Chinese medicine powder is generally made of Chinese medicinal materials such as Panax notoginseng, ginseng, salvia miltiorrhiza, ganoderma lucidum, licorice, Liushen, rhubarb, bletilla striata, Xiyang ginseng, sealwort, spirulina, pearls, etc., which are ground or air-pulverized into single powder or compound powder (mixed ) after sieving by pharmaceutical powders sieving machine, the main purpose is to remove impurities and remove large particles.
Removal of impurities and large particles. During the sieving process, traditional Chinese medicine powder dust is serious. It not only causes valuable powder loss, but also exposes on-site operators to dust for long periods, causing operator discomfort and material loss.

The ground pharmaceutical powder has a lot of fiber content and is difficult to sieve. The specific gravity is light. During the sieving process, the sieving equipment can not meet the screening needs of the site due to the fact that the material is easy to clump during the sieving process and block the screen. Our sieving machine equipped with an ultrasonic anti-clogging system uses revolutionary innovative technology to sieve fine powder, and the pore size can reach 20 microns. The industrial ultrasonic sieving machine can also increase screening capacity and reduce screen damage.
1. The addition of an ultrasonic anti-blocking device improves the quality of powdered medicines, increases production capacity and ensures accurate particle size separation. Reduce the mesh size to 20 microns (635 mesh).
2. Provide up to five powders in one operation, ensuring the highest quality sieved products to meet requirements, an innovative solution for peace of mind for customers.
3. It also reduces production downtime by preventing screen clogging and breakage, and reduces man-hours required to clean screens.
4. It is made of SUS304 or 316L stainless steel. The inside and outside of the sieve machine are polished, clean and hygienic, without dead ends, easy to clean and disinfect, and meet the hygienic standards of the pharmaceutical industry.
5. Automatically process the screened pharmaceutical impurities and particles. After screening, it can automatically enter the next round of screening work, saving labor and continuous operation.

Pharmaceutical powders sieving machine is mainly used in the pharmaceutical industry to remove impurities in various types of pharmaceutical powders. The sieving machine sieves layer by layer through sieves with different meshes. The coarse material remains on the sieve, and the fine material is sieved smoothly to achieve effective Screening action. It can be used to screen out fine powder or impurities, such as screening of Chinese medicinal materials, removal of debris and impurities, and powder classification to meet the requirements of pills, powders and other preparations.

Case: Panax notoginseng powder (200 mesh)
Background: A Chinese herbal medicine producer used a conventional vibrating sieve to process Panax notoginseng powder. The material tended to clog the screen, causing frequent production stops and manual cleaning.
Solution: We recommended the DHC-600 pharmaceutical powders sieving machine with an ultrasonic anti-clogging system.
Result: Screen clogging was reduced. Continuous operation time was extended, and cleaning frequency decreased. The customer reported more stable production and less material loss.
A: SUS304 standard, SUS316L optional for corrosive or high-purity applications. Both can be mirror-polished to reduce residue and microbial adhesion risk.
A: The sieve frame uses a quick-release modular design, so the screen, frame, and gasket can be removed without tools. We can provide material certificates and a cleaning procedure document to support GMP validation.
A: Yes. Explosion-proof motor and fully enclosed structure are available. Optional nitrogen purge and dust collection interfaces can be added. Please specify your ATEX zone when inquiring.
A: DHC-400 is approximately 0.8 × 0.6 × 0.9 m. DHC-600 is approximately 1.0 × 0.8 × 1.0 m. Larger models range up to 2.2 × 1.8 × 1.5 m, depending on screen layers and accessories.
A: No special tools required for standard models. The clamp-ring design allows manual replacement. For 3 or more layers, a simple lifting aid is recommended.
A: The machine uses a fully enclosed structure with sealed covers and gaskets. Optional dust collection interfaces can connect to your central vacuum system. A closed-loop system is available for high-value powders.
