OEM Granules Manufacturer & Supplier: Precision Engineering & Global Compliance

MedGence (Yineng Pharma) uniquely bridges fundamental phytochemistry research with enterprise commercial manufacturing. Unlike conventional toll manufacturers, our facility in Changsha houses 300+ scientific specialists, pilot plants, and certified laboratories. We oversee the entire lifecycle: botanical active screening, origin/seasonal potency optimization, HPTLC/HPLC analytical validation, LD50/genotoxicity testing, clinical trial protocols, and commercial-scale fluidized bed or dry roller granulation under strict non-disclosure protections.

Natural botanical raw materials are vulnerable to climatic, soil, and harvest-window variations. We control this upstream by standardizing geographic provenance (Daodi origin) and testing raw materials via multi-wavelength chromatographic fingerprinting. During extraction and spray drying, our automated process control loops regulate critical process parameters (CPPs) such as inlet/outlet temperatures, spray rates, and vacuum pressure. Finished granules must demonstrate a chromatographic similarity coefficient ≥ 0.95 against the validated reference standard.

We formulate according to the client's localized clean-label regulations. Rather than relying on traditional maltodextrins or corn syrups, we utilize prebiotic carriers such as resistant dextrin, organic acacia gum, inulin, isomalt, or microcrystalline cellulose (MCC). For sugar-free instant beverages, we achieve rapid dissolution and clean mouthfeel using natural monk fruit extract, Reb-M steviol glycosides, and erythritol combinations that maintain excellent flowability without moisture caking.

We employ microencapsulation via Wurster fluid-bed bottom spray coating. By enveloping bitter botanical cores in thin layers of pH-responsive cellulosic matrices (e.g., ethylcellulose, hydroxypropyl methylcellulose) or vegetable lipids, the active is shielded from lingual taste buds. The coating remains intact throughout the oral cavity and dissolves instantaneously upon reaching the gastrointestinal tract, preserving bioavailability while maximizing patient compliance.

Yes. We supply comprehensive CMC (Chemistry, Manufacturing, and Controls) technical dossiers, including 3-batch commercial validation reports, full accelerated and real-time stability data (ICH guidelines), validated analytical testing procedures, pesticide screening according to USP <561>, heavy metal limits by ICP-MS, and microbiological verification according to USP <2021>/<2022>. Our regulatory team directly coordinates with foreign importers for swift registration approval.

For laboratory R&D screening and analytical method development, initial pilot runs can be initiated at 5 kg to 20 kg batches. Commercial OEM granule production runs generally start at 300 kg to 500 kg for custom specialized formulas, with capacity scaling seamlessly to tens of metric tons per month. Standard lead times from final formulation sign-off and raw material release to packaged commercial delivery range from 4 to 6 weeks.

We offer both bulk intermediate packaging (pharmaceutical-grade polyethylene double-lined bags enclosed in fiber drums with desiccant seals) and retail-ready finished packaging. Retail formats include high-speed 3-side or 4-side sealed sachet pouches (0.5g to 15g), multi-lane stick packs, HDPE pharmaceutical bottles with induction seals, and automated carton pack-out lines with serial barcode tracking.
