Dryer
A high-precision, GMP-compliant drying system offering ±0.1% moisture control, inert gas protection, real-time monitoring, and multi-process flexibility—ideal for heat-sensitive and oxidation-prone solid dosage forms.
This advanced pharmaceutical drying system delivers exceptional precision, material protection, and regulatory compliance for solid dosage manufacturing. It achieves moisture control accuracy of ±0.1% through real-time online monitoring using near-infrared (NIR) or capacitive sensors, automatically adjusting drying parameters to ensure batch-to-batch consistency. With material moisture deviation ≤0.2%, the system employs hot-air circulation and multi-point temperature sensing to eliminate hot or cold spots, significantly enhancing product stability.
Designed for sensitive APIs, it supports low-temperature drying (30–60°C), preserving ≥99% bioactivity in thermolabile compounds like vitamins and biologics. An optional inert gas (N₂/Ar) environment prevents oxidation of vulnerable materials such as herbal extracts and peptides. The integrated agitation or fluidized-bed design ensures uniform heating without agglomeration, maintaining particle integrity and flowability (angle of repose ≤30°)—critical for downstream tabletting and capsule filling.
Energy efficiency is a key advantage: the system uses 40% less energy than conventional ovens and dries 100 kg of wet granules in just 2–4 hours, cutting processing time by over 60%. All product-contact surfaces are made of 316L stainless steel and PTFE, meeting USP Class VI standards with zero leachables or adsorption.
Fully compliant with GMP, FDA 21 CFR Part 11, EU GMP Annex 11, and ICH Q9, the system features tamper-proof Electronic Batch Records (EBR), full traceability via barcode/QR code, and supports CIP/SIP (121°C) for zero cross-contamination. It carries CE, ISO 9001, and ASME BPE certifications, and its IP65-rated electrical system ensures safe operation in cleanrooms.
With flexible capacity (10–1000 kg/h), support for multiple drying technologies (fluid bed, vacuum, freeze, microwave), and seamless integration into granulation–drying–milling workflows, this system adapts to R&D, pilot, and commercial-scale production. Intelligent controls include PLC + touchscreen interface, 100+ encrypted drying recipes, remote monitoring, and self-diagnostic fault detection. Comprehensive safety features—overpressure protection, thermal cutoff, emergency stop, and optional Ex tD A21 explosion-proof design—ensure operator and equipment safety, while low-maintenance components and guided servicing minimize downtime.
