The Role of Sieving Machine in Pharmaceuticals
The sieving machine in pharmaceuticals is vital. It is mainly used for screening, filtering, and grading raw materials to ensure product quality and purity. Here are the key functions of pharmaceutical sieving machines:
- Coarse and Fine Screening of Raw Materials
In pharmaceutical production, raw materials undergo both coarse and fine screening to eliminate contaminants and ensure their purity. - Impurity Removal
Impurities present in pharmaceuticals can impact product quality, and sieving machines are used to efficiently remove these impurities from raw materials. - Material Grading
Sieving machines sort raw materials into various grades, making it easier to handle them according to specific production stages. - Filtration
Sieving machines also filter raw materials, eliminating unwanted substances and enhancing the overall purity and quality of the ingredients.
Sifting in Pharmacy
Sifting in pharmacy involves passing raw materials, powders, or granules through a sieve to remove large particles and impurities. This process helps ensure uniform particle size, which is essential for accurate mixing, dosage precision, and product consistency. It also aids in breaking up particle clumps and improving material flow, which is important for further production steps such as tablet or capsule formation.
Chinese Herbal Medicine Production
In the production of Chinese herbal medicines, sieving machines help ensure uniform particle size after raw materials are crushed. This is critical for effective mixing and processing. Vibro sifters specifically designed for pharmaceutical use are commonly employed to sieve powders, meeting strict pharmacopeia standards to guarantee the purity of herbal powders.
Types of Pharmaceutical Sieving Machines
Various types of sieving machines, including stainless steel rotary vibro sifters and linear vibrating screens, are used in pharmaceutical manufacturing. These machines screen not only raw materials but also intermediate products and finished medicines. Many manufacturers use rotary vibrating sieves for initial screening to enhance raw material purity, improving the overall quality of pharmaceutical products.

Sieve Sizes in Pharmaceutical
Pharmaceutical sieve sizes range from 20 mesh (for coarser materials) to 400 mesh (for finer materials). The appropriate sieve size depends on the specific particle size requirements of the material being processed. Finer sieves ensure uniform particle sizes, while coarser sieves handle bulkier materials and larger particles.
| Materials | Proportion | Mesh | Processing Method | Capacity (kg/hr) | Model |
|---|---|---|---|---|---|
| Medicinal powder | 0.8 | 60,80 | Dry | 600kg | SY-800-1S |
| pill | 0.7 | 20/60 | Dry | 1000kg | SY-1000-2S |
| Chinese herbal | 1 | 20 | Wet | 1500kg | SY-1200-2S |
| Chinese medicine extract | 80/150 | Dry | 1800kg | SY-1500-1S |
