YOKO Capsule Polishing Machines: Efficient Surface Treatment for Gelatin & Vegetable Capsules
In the automated production of empty capsules and filled capsule products, surface quality and cleanliness directly affect product appearance, qualified rate and market acceptance. YOKO BIOPHARM provides a full series of “Capsule Polishing Machines” (including JPG-2, JPG-3A-R, RJPG-H models), specially designed for polishing, dust removal, sorting and defect rejection of hard empty capsules. They are widely compatible with Gelatin Capsules and Vegetable Capsules in sizes 000#–5#, helping manufacturers achieve stable, efficient and standardized post-processing.
1. Core Functions
YOKO capsule polishing machines integrate multiple practical functions to solve common problems in capsule production:
Dust & Powder Removal: Effectively clean residual powder, fragments and floating dust on capsule surfaces, ensuring clean and tidy appearance.
Surface Polishing & Smoothing: Improve surface gloss, eliminate minor scratches and burrs, especially suitable for high-standard pharmaceutical and health product packaging.
Automatic Defect Sorting: Automatically reject deformed, broken, unclosed or unqualified capsules, reducing manual inspection cost.
Low Damage Rate: Gentle roller conveying structure protects capsule shape, avoiding cracking or deformation during polishing.
