YOKO-GB-A
High-efficiency Tablet Film Coating Machine
YOKO-GB-A is a compact tablet film-coating family with 3, 5, and 10 kg batch references. Drum-speed ranges extend to 24 rpm on the smaller configurations and 21 rpm on the 10 kg model. The series is suited to development and small-batch coating work where coating uniformity, spray conditions, inlet-air treatment, exhaust, product temperature, cleaning, and recipe transfer must be reviewed together.

Equipment purpose
What this machine is designed to do
The machine applies an atomized coating suspension or solution to moving tablets while conditioned air supports drying. It is intended for film-coating development, clinical or pilot batches, small commercial batches, and process work that benefits from a contained rotating pan rather than an open coating vessel.
Operating sequence
Working principle
Tablets tumble in a perforated or configured coating drum while spray guns deliver the coating liquid across the moving bed. Prepared inlet air passes through the tablet mass and removes solvent or water through the exhaust path. Spray rate, atomization, pan speed, airflow, temperature, tablet load, and gun position must remain balanced to avoid overwetting, spray drying, twinning, erosion, colour variation, or incomplete coverage.
Review points
- Three reference batch sizes support scale comparison at 3, 5, and 10 kg.
- Published pan-speed ranges provide an initial mechanical window; the validated range depends on tablet load and tablet strength.
- The process review connects spray delivery with inlet air, exhaust, product temperature, and coating-liquid preparation.
- Small-batch operation still requires defined gun setup, droplet control, sampling, endpoint criteria, and cleaning verification.
- Utilities and room interfaces should account for air handling, exhaust, electrical supply, and any solvent-related safety controls.
- A scale-up plan should compare bed depth, spray area, drying capacity, mixing pattern, coating time, and weight gain rather than transferring time alone.

Selection questions
Frequently asked questions
Is the maximum batch size the normal working load for YOKO-GB-A?
Not necessarily. A coating pan needs enough tablet bed movement for mixing and enough free volume for circulation. Tablet density, shape, friability, coating objective, bed depth, and spray area affect the useful working range. Minimum and maximum validated loads should be agreed through trials rather than assumed from the model label.
Which process data should be provided for a film-coating quotation?
Provide tablet dimensions and weight, batch size, coating type, solvent system, target weight gain, expected coating time, inlet-air conditions, exhaust availability, room constraints, cleaning method, and required process records. Safety and emission controls must be defined for any solvent-containing process.
How is coating uniformity evaluated during a trial?
The protocol can track weight gain, colour or appearance variation, defects, tablet temperature, inlet and exhaust conditions, spray rate, atomization pressure, pan speed, and sampling time. The agreed acceptance method should reflect the actual coating objective; visual appearance alone may be insufficient for a functional coat.
Can a 3 kg recipe be transferred directly to the 10 kg model?
A recipe can provide a starting point, but scale-up should account for bed depth, mixing pattern, spray-zone coverage, drying capacity, gun-to-bed distance, atomization, and tablet exposure. Matching only pan speed or coating time can produce a different product result.
What supporting systems may be required with YOKO-GB-A?
Depending on scope, the project may require coating-solution preparation, filtered and conditioned inlet air, exhaust ducting, dust or solvent treatment, compressed air, wash equipment, drainage, and room controls. The quotation should state which systems are included and which remain part of the buyer's facility.
