HSZP rotary Tablet Press machine with Pre-Pressure & Main Compression
high speed HSZP tablet press with European standard D tooling
All the machines in the HSZP range are exceptionally fast and powerful, yet the LCD touch screen display is so intuitive in its operation that operator training need not be extensive. More advanced users will find that there is plenty of scope for refining the operating parameters, but the simple automatic operation options let you get up and running quickly.
Obviously these are machines intended for large production runs, and with so many cutting heads the dies are not going to be changed on a whim. But they are very simple to change when the need arises.
It can be a little overwhelming to see so many tablets being produced so rapidly, but after a while the novelty wears off and the user is free to concentrate on more mundane matters. The automatic lubrication system greatly reduces the time commitment needed to keep these machines running, and the forced feeder does a good job of helping with consistent dosing to ensure accurate tablet weights.
Anyone used to using an older style tablet press, with numerous bolts and wheels for adjusting the machine’s parameters, will find the HSTP range a revelation. Not only is electronic adjustment faster and easier, it is also more accurate and easier to reproduce for future batches. In fact, these machines have an excellent facility that allows recipe settings to be stored and reproduced for future use.
Thanks to the enclosed turret and powder suction device you do not have to worry about dust floating around, making the working environment much more pleasant than with many other tablet pressing machines.
How does Pre-compression compare to Main Compression? Why are they Critical?
Rotary type of tablet machines incorporates a two-step compression process of tablets.
Here, granulation undergoes a first compression where it is compacted under light compression.
This first stage of compression is what we refer to as pre-compression.
After pre-compression, the tablet undergoes a second compression stage which is referred to as the main compression.
Here, a higher compression pressure is applied on the compact to ensure the proper hardness of the tablet is achieved.
The pre-compression stage, note, is usually applied to eliminate entrapped air from tablet formulations.
Lots of air in the powder can significantly affect the integrity of the tablet.
