Wet granulation technology is a core process in modern solid dosage manufacturing. Its fundamental principle involves precisely adding liquid binders to pharmaceutical powders, utilizing the liquid bridging and physical bonding effects of the binder to agglomerate loose powders into solid granules that meet process requirements.
In the specific operational workflow, the powders and binders are first subjected to high-intensity uniform mixing. Subsequently, the materials enter the core granulation zone, undergoing distinctly different physical shaping processes depending on the equipment type. Extrusion granulation relies on dies to force the soft mass into strands before cutting; agitation granulation depends on high-speed rotating impellers to continuously shear and mix the material; rotary granulation utilizes the friction and centrifugal force of a rotating pan to agglomerate the material; and fluidized granulation achieves powder agglomeration by spraying binders into an air-suspended state.
These complex and diverse mechanical stressing processes impose extremely high requirements on the geometric precision and wear resistance of the underlying components. We can perform precision machining for wet granulation equipment based on various forming principles, according to customer-provided design drawings. Whether it involves high-hardness extrusion dies that must withstand extreme extrusion pressures, high-speed mixing impellers requiring complex streamlined curved surfaces, or fluidized air distribution plates with strict demands for porosity and surface finish, Hansheng Automation supports the exact manufacturing of various non-standard components according to customer prints. By strictly controlling micron-level machining tolerances and implementing pharmaceutical GMP-compliant surface treatments, we effectively enhance the anti-adhesion and wear-resistant capabilities of critical contact parts.
The formed wet granules typically require further processing by sizing equipment to achieve a more rounded and uniform appearance, followed by entering a drying system to remove excess moisture and yield the final dry granule product.
Benefiting from scientific mechanical stress distribution and precise forming processes, granules produced by wet granulators possess significant advantages, including uniform quality, excellent aesthetics, strong wear resistance, and superior compressibility. This makes them particularly suitable for tablet and capsule production in the pharmaceutical industry. Hansheng Automation consistently leverages its professional build-to-print customization capabilities to provide high-quality non-standard part custom services for granulation machinery manufacturers, utilizing robust machining technology to ensure your equipment stably delivers outstanding performance on demanding pharmaceutical production lines.
