Trace every capsule lot back to its gelatin batch, pigment and drying run.

An empty capsule is a simple object that hides a long chain of dependencies. Gelatin or HPMC arrives by lot with its own bloom or viscosity figure, and the supplier’s analysis rarely sits beside the dipping record that used it. Pigments join by the kilogram. Weeks later a filler reports a locking problem on size 0, and someone must find which dipping run made those shells. That search is slow.

Management software for capsule plants keeps the solution batch, the dipping machine, the drying hours and the finished lot together. It follows one size and colour from gelatin receipt to the carton on the pallet, so a filler’s question has one place to look.

A pharmaceutical or nutraceutical filler orders empty shells by size, colour, print and carton count, often against a specification of its own. The plant prepares a gelatin or plant polymer solution, adds colour, and holds it at temperature in a jacketed tank. Pins dip into the solution, rotate through drying kilns, and the dried shells are stripped, cut to length and joined cap to body.

Printing, sorting and visual inspection follow, with every printed lot tied to an artwork version, an ink lot and a sorter count that the quality head can open at any time. Samples go to the laboratory for moisture, disintegration, lock length and wall thickness. Rejected shells are counted by defect. Dents, splits and double caps are separate lines. Approved lots are packed in lined cartons with a lot label and a certificate of analysis. A filler may ask about a lot a year later. Every figure must still be findable.
