Semi-Continuous Coater for the
pharmaceutical industry

Continuous Coater - KOCO®

In recent years, continuous manufacturing has become a very important topic for pharmaceutical companies, suppliers to the pharmaceutical industry and supervisory authorities throughout the entire world. As a technology-driven machine engineering company, L.B. Bohle Maschinen + Verfahren GmbH has been working on this issue for years and is offering its customers continuously operating processes ranging from stand-alone systems to the complete production line QbCon®.

A highlight in the continuous machine product portfolio is KOCO®, a semi-continuous coating solution.

Coating with the L.B. Bohle
semi-continuous coater

In 2011, L.B. Bohle introduced KOCO®, the first semi-continuous coater for the pharmaceutical industry, to the market. The KOCO® is designed as a semi-continuous coater and stands out for its high throughput. At the same time, the process machine is based on the proven patented L.B. Bohle design for tablet coaters.

Differences between continuous coaters and batch coaters

Unlike conventional batch coaters, KOCO® allows the feeding of tablet cores through a product inlet on the top of the machine.

Design and process cycle of the semi-continuous coater

The coated tablets are discharged though a corresponding opening at the front of the coater. The process control is designed to operate in a cyclic manner, repeatedly executing the defined recipe, with each repetition called a cycle.

Raman process analytics

A built-in Raman probe helps the operator recognize the end point of the coating process.
