The PR-3500 Series Triple Layer Tablet Presses



View of PR-3500 Triple Layer Tablet Press with Doors Closed

The PTK PR-3500 "Diamond" Series is a high speed tablet press capable of producing one layer, two layer and three layer tablets. The PTK PR-3500 tablet press is designed for today's current cGMP pharmaceutical manufacturing environments.

 

The PR-3500 Series presses features an efficient layout providing easy access to the interior for cleaning and maintenance.

The PS-Con control and data acquisition software incorporates the PWR (PharmTech Weight Regulation) system utilizing displacement and force sensors to effectively monitor and regulate tablet weights within a user specified range. The PS-Con 21 CFR Part 11 compliant software features a user-friendly HMI interface that allows for recording and control of all main process  parameters, events and allows for establishment of recipe files. Data acquisition affords the ability to learn more about a product's compression characteristics so that the manufacturer can optimize tablet compression and downstream processes for greater efficiency.

PTK's multi-layer tablet presses are equipped powder scrapers necessary to keep the different powders segregated from one another and recirculators to recycle the powders back into the feeders.

The zero-clearance powder feeder continuously applies a force onto the die table, thereby, reducing dust and material loss. The feeder and feeder base can be dismantled without any special tools. Different types of impellers and optional powder feeding solutions can be used to improve the feeding of poorly flowing powders.

The press is built around a robust frame constructed to withstand the considerable forces encountered during rotary press operation. Identical, vibration free pre- and main- compression rollers are controlled by servomotors that provide precise positioning. Internal covers are fitted to prevent dust from migrating into the roller assemblies and cam tracks. The covers can be easily fitted and detached without tools.

A wide range of options are available for the press and the customer will benefit from AC Compacting's extensive tablet press experience and philosophy of customer support.
