Tablet Coater for the pharmaceutical industry
Tablet Coater - BTC
Tablet Coaters ensure a precise coating of tablets and change the tablet properties in terms of taste, stability, colour or swallowability. In addition, release properties can be changed or the Active Pharmaceutical Ingredient (API) can be sprayed on.
More about the highlights
The Bohle Tablet Coater BTC stands for economical tablet coating. A flat tablet bed, patented air guidance and high spray volumes ensure quality and reduce process times by up to 35 %. The BTC sets standards with the best mixing and thus ensures high uniformity of the film application.
Successful film coating processes are based on three basic operations: Spraying, drying and mixing. Each individual production stage must be carefully planned and optimised in coordination with the others. The BTC Tablet Coater sets standards in terms of quality and efficiency.
In the BTC Tablet Coater, optimum running of the cores is ensured by a flat tablet bed in a long drum geometry. The systematic forced guidance in the drum ensures constant movement of the filling material. No twins are formed. Loss of solids and coating is extremely low. Innovative concepts, both in terms of the process and cleaning, improve the functionality of the Tablet Coater and deliver excellent results.
The air flow achieves significant process-related advantages, as there is no longer any risk of spray drying of the suspension. This reduces spray losses and improves the structure of the coating.

What makes the BTC Tablet Coater particularly efficient?
The BTC shortens process times by up to 35 % thanks to a flat tablet bed, first-class air guidance and high spray volumes - this ensures faster and high-quality coating processes.
The BTC reduces process times by up to 35 % thanks to a flat tablet bed, patented air guidance and high spray volumes - this ensures faster and high-quality coating processes.
Thanks to the mixing spirals, uniform mixing is achieved without tablet breakage or twinning, which guarantees uniform and high-quality film application.
What advantages does the BTC offer in terms of handling and cleaning?
The tablets are fed gently and continuously and can be emptied quickly and completely by reversing the direction of rotation of the drum. The machine also enables quick and easy cleaning.
How easy is it to operate the BTC?
The BTC is equipped with a user-friendly multi-panel visualisation and touch panel operating unit, which enables simple control, monitoring and recipe management directly at the coater.
