Lödige Tablet-Coater

The Lödige Coater has been specifically designed for the coating of tablets. With this system, Lödige has grown to be the technology leader for Coating Systems in the market.
The combination of maximised tablet bed surface area, the large number of spray nozzles and high inlet air flow rates allow the spraying of a maximum liquid quantity within a short time. The new concept for the air channelling ensures almost turbulent free air flow, allowing the drying air to be used in a very efficient manner and being gentle to the product at the same time. These characteristics allow for a reliable coating process and short process times. Furthermore, the almost absence of any turbulence in the air channelling prevents the formation of fouling from the beginning, thus minimising the cleaning.
The use of modern sensors optimises the spraying and drying process. An easy and reliable adjustment possibility of the spray arm makes the handling easier too.

ADVANTAGES

Variability of filling degree without having to change the coating drum: the reduced height of the mixing elements enables a flexible working volume.
Uniform coating and short process time: large number of mixing elements and nozzles to ensure an optimal and uniform spraying of the coating solution.
High speed = time is money: high drying efficiencies, high spray flow rates achievable thanks to a uniform air distribution over the entire drum.
Optimal air channelling: quality improvement: optimal air channelling prevents spray drying, increases the service life for campaign production and reduces the cleaning.
Easy cleaning: the use of complex cleaning technology with its high mechanical effect ensures quick and effective cleaning. This saves money, cleaning agent and energy.

OPTIONS    

Explosion proof: design suitable for use with organic solutions (acetone, isopropanol, ethanol)
Fully automatic spray arm: adjustment of the spray arm is patent pending. Not only the clearance between the nozzle and the tablet bed is adjustable, but also the spray angle to the tablet bed.
Sugar coating: Lödige Coater can be equipped for the production of film tablets as well as dragees.
Mini-tablets or pellets: drum perforations are available in different sizes to suit the product.
Qualification: complete qualification documentation incl. risk analysis based on design documents, GAMP5 documentation.

Production and Laboratory Sizes

In addition to various production sizes, Lödige also provides a laboratory version of type LC Lab.
The Lödige Laboratory Tablet Coater is a modular unit capable of being equipped according to the individual requirements of the customer.
Designed to be multi-purpose, this Coater is not only easy to operate but enables quick and efficient processing. Parts to be dismounted are all lightweight.
The drum and the spray arm can be partitioned in order to process small quantities (0.6 l).
The Coater and the liquid supply stations are made of Corian® - a high-resistant and light material complying with FDA – which gives the unit a functional and modern design.
The Laboratory Coater is to be understood not only as a laboratory unit, but also as a complete coating system which can operate under the same process conditions as the production coaters.
