Tablet Coating

Tablet coater


Tablet coating is an important process step in tablet production. The pharmaceutical industry needs solutions that meet coloring and taste-masking requirements, as well as high demands from applications such as enteric coatings, controlled release coatings or the addition of an active ingredient. With our vast experience from the former Manesty brand, combined with Hüttlin’s strong innovation and process expertise in mixing, spraying and drying, Syntegon has created a new benchmark for tablet coating: our new Sepion tablet coater.

Key benefits

Fast and robust processes
With an optimized drum geometry and matching spraying system, you can achieve higher spray rates and significantly shorter process times.
Verified batch size flexibility
The Sepion coater achieves verified filling levels between 10 and 100% without the need to change the mixing baffles.
Go for full service
Whether you need process support, rental equipment, or a service agreement – we take your molecules to production.

Features of our tablet coater​

Closed, clean and contained

The Sepion drum coater is designed for closed charging, sampling, and discharging. Its door is equipped with 3-clamp connections that allow for flexible interfaces, e.g. for a containment upgrade for coating tablets with highly potent active ingredients. Additionally, Sepion comes with a fully automatic cleaning system.

A drum like no other

The extended drum length ensures a shallower tablet bed and results in a higher coating frequency per tablet, while allowing for an increased number of spray guns. The result: high spray rates and shorter process times. The 51% open drum area further supports a higher drying capacity.


Flexible batches and uniform mixing

The drum of our Sepion coater is unique: its fully welded mixing baffles achieve filling levels between 10 and 100% with no baffle changes. At the same time a 100% filling level ensures uniform blends with a relative standard deviation of less than 3% in less than 8 minutes.

An automated spray arm

Our drum coater comes with an automated spray arm. Depending on the filling level, you can adjust the optimum gun-to-bed distance via the HMI. This allows you to maintain the ideal spray angle without further manual intervention and enhance operator safety.

Sensoric efficiency

An optional laser measures the gun-to-bed distance and allows for a fully automated recipe-driven adjustment, eliminating the need for manual operator intervention. For temperature-sensitive products and maximum product safety, the Sepion coater can be equipped with an infrared sensor to accurately measure the tablets’ surface temperature.


Spray arms for all needs

The standard spray arm of our Sepion coater provides anti-bearding spray guns with individual supply tubes for liquids. The optional Pro version has a common liquid and compressed air supply that integrates all hoses and features a tool-free quick-release system, avoiding misalignment and further reducing set-up and cleaning times.

High-quality cleaning

With our cleaning systems, we aim for the highest efficiency. Depending on the product and available cleaning media on site, you can choose between different cleaning skids. A zoned, recipe-driven system combined with cleaning nozzles for all product contact surfaces achieves reproducible and validatable results.

Are you looking for a solution for early-stage development?

Our tabletop unit Solidlab 1 enables you to test small R&D batches in a fast and easy way. As an ideal solution for your feasibility studies, it can be equipped either with a fluid bed or a drum coater module. The drum coater version comes with two different drums for batches from 0.25 to 1.2 kg. Unlike most other solutions in the market, the Solidlab 1 comes with our PROVICON control system featuring open recipe creation and management for a time-saving product development.


Use case scenarios

Tablets at their best

Outstanding granule properties like smooth flowability and an ideal particle size distribution result in excellent compression characteristics – even at very low API concentration, e.g. for cancer therapy.
