Compact tablet press of the ZP series (ZP-5/7/9)

The ZP Series (ZP-5/7/9) is a range of compact, single-sided rotary tablet presses engineered for versatility across the pharmaceutical, chemical, food, and electronics industries. Despite their small footprint, these machines deliver industrial-grade performance, making them the gold standard for pilot batches and specialized small-scale manufacturing.

Built entirely from stainless steel, the worktable and turret undergo specialized hygienic treatments to prevent cross-contamination and ensure full GMP compliance. The system is powered by a variable frequency drive for smooth speed adjustments and includes an electromagnetic braking motor, allowing for safe manual adjustments during setup.

For optimal results, it is recommended to use dry powders (moisture content $\leq 5\%$) with good flowability (20–60 mesh). The machine is capable of producing both round and irregular-shaped tablets with high consistency.

Operational Principles

• Feeding: Manual or hopper-assisted loading of the powder into the feed frame.

• Dosing: Precise filling of the die cavities to ensure weight uniformity.

• Compression: Application of up to 60 kN of pressure to form the tablet.

• Safety Monitoring: Integrated overload protection system that triggers an automatic stop if the maximum pressure is exceeded.

• Ejection: Smooth mechanical ejection of the finished tablets into the discharge chute.

Key Features

• Hygienic Design: All-stainless steel construction with non-porous surfaces for rapid cleaning and sanitation.

• Advanced Control: Frequency inverter for step-less speed control and an electromagnetic brake for instant stopping.

• Overload Protection: Mechanical and electrical safety buffers prevent damage to the tooling and the machine frame.

• Transparent Shielding: Fully enclosed pressing zone with transparent windows for safe visual monitoring of the process.
