Grand Machinery designs and manufactures high-performance coating machines for the pharmaceutical, food and chemical industries. Every coating machine we build combines precision spray technology, intelligent PLC control and GMP-compliant construction to deliver uniform coating results, higher yields and lower operating costs — batch after batch, year after year.
Grand Machinery offers a full range of coating machines — from high-efficiency intelligent models to integral and poreless designs — covering batch sizes from laboratory scale to full industrial production. Each coating machine is precision-engineered for uniform film application, stable operation and simple maintenance, giving you the flexibility to scale production with confidence.
A flagship model that pairs a PLC touch-screen control system with automated spray, precise temperature and humidity regulation, and real-time process monitoring. Built for tablet and capsule film coating, this coating machine delivers uniform coating thickness, consistent appearance and a high solution recovery rate that minimizes waste. Its GMP-compliant stainless steel construction and CIP-friendly cleaning design allow fast changeovers between batches.
BG260 High Efficiency Intelligent Coating Machine is a premium, large-capacity solution designed for industrial pharmaceutical and food tablet coating. Featuring a massive 260L batch capacity, precise temperature control, and an intelligent automated system, this machine ensures exceptional coating uniformity, high production throughput, and superior consistency for large-scale manufacturing operations.
An integrated coating machine solution that merges the coating pan, spray system, air handling unit and control cabinet into one compact unit. The all-in-one structure simplifies installation and reduces factory footprint while maintaining high drying efficiency and stable coating performance — an ideal choice for medium and large batch production in pharmaceutical and food plants.
A poreless coating machine featuring a sealed, hole-free drum that keeps the coating solution fully inside the pan, producing a smoother finish and higher solution utilization. The airtight structure is especially suited to sugar coating, candy coating and moisture-sensitive products, offering superior hygiene, easy cleaning and a cleaner working environment.
Complete supporting systems to maximize the performance of your coating machine: high-precision spray guns, peristaltic dosing pumps, solution tanks, air compressors and process control software. Every piece of auxiliary equipment is matched to Grand Machinery coating machines for seamless integration, consistent spray patterns and reliable long-term operation.
Advanced PLC and HMI systems enable automatic parameter setting, recipe management and real-time data recording. Operators can reproduce proven coating machine processes at the touch of a button, reducing human error, saving materials and improving overall equipment effectiveness (OEE).
From pre-sale process consulting and workshop layout design to installation, commissioning, operator training and spare parts supply, Grand Machinery provides end-to-end support. Our international service network ensures fast response, minimal downtime and maximum return on your coating machine investment.
Every coating machine is manufactured to strict quality standards using premium stainless steel, precision-welded drums and calibrated spray systems. The result: uniform coating thickness, smooth surfaces and batch-to-batch consistency that meet the most demanding pharmaceutical and food quality requirements.
Grand Machinery coating machines follow a precise, automated workflow designed for consistency, repeatability and efficiency.

Coating Machine FAQ: Sizing, Process Control & Troubleshooting
Load the pan to 30–60% of volume; gives the example that a 150 L pan suits ~60–80 kg of tablet load, balancing spray coverage and drying airflow.
Perforated pans suit aqueous film coating (fast drying); poreless pans retain solution inside the drum, ideal for sugar coating, chocolate panning, and moisture/solvent-sensitive products. Some models accept interchangeable drums.
Yes, by configuring spray guns, air handling and pan-speed range, with a validated changeover between the fast-drying perforated process and the slow, gentle poreless process.
Independent control of atomizing pressure, gun-to-bed distance, pan speed, inlet/outlet temperature and exhaust balance, with proven parameters stored in the PLC recipe library for batch-to-batch repeatability.
Solvent-based uses an ATEX/explosion-proof version with flameproof motors, static grounding and solvent-recovery exhaust; aqueous uses a standard clean-air unit.
Multi-gun spray + calibrated peristaltic dosing + balanced exhaust typically achieves 85–95% utilization, cutting material cost and waste.
CIP-friendly poreless/ribbed pans with spray balls, smooth welds and drain ports; rinse- and swab-sampling points support GMP validation; changeovers are documented and reproducible via PLC recipe management.
