ZPT Series Automatic Rotary Tablet Press (ZPT-15/17/20/25)

The ZPT Series Automatic Rotary Tablet Press is a high-performance solution designed to compress powder mixtures into tablets with uniform mass and exceptional structural integrity. Engineered for high-speed operation, the series features a hermetically sealed housing and wide inspection windows, ensuring process visibility while protecting the operator from dust and noise.

The ZPT series is distinguished by its advanced sealing technology; specialized anti-leakage and dust-proof seals prevent lubricant contamination of the product. Additionally, the integrated forced-feeding system utilizes a direct drive to ensure the die cavities are filled consistently, even when working with materials that have challenging flow characteristics.

Operational Principles

• Loading: The powder mixture is gravity-fed into the main hopper.

• Forced Feeding: A direct-drive paddle system ensures stable and uniform distribution of the material into the dies.

• Pre-Compression: A preliminary squeeze removes air from the powder, preventing capping and stabilizing the tablet "slug."

• Main Compression: High-force punches finalize the tablet to the target hardness and thickness.

• Ejection: Finished tablets are pushed out and directed to the discharge chute.

• Rejection: Integrated sensors allow for the identification and removal of defective tablets (optional configuration).

Key Features and Advantages

• Standardized Tooling: Full support for European standard EU D, B, BB, and BBS type punches and dies.

• Hygienic Integrity: Fully enclosed workspace with advanced seals to prevent cross-contamination and oil leakage into the product zone.

• Forced Feeding System: Direct-drive shaft and paddle design optimize filling efficiency and increase throughput.

• User-Friendly Maintenance: The modular design simplifies the cleaning of components and reduces the time required for format changeovers.

• Regulatory Compliance: Designed and manufactured to exceed GMP, ISO, and FDA requirements for sterile and non-sterile pharmaceutical production.
