The TIANHE GZPK-45 and GZPK-55 represent the pinnacle of speed tablet press machine engineering for mid-to-large tablet production. As a double-sided rotary tablet press equipped with automatic tablet weight control and intelligent rejection systems, this machine delivers unmatched precision and throughput for pharmaceutical, nutraceutical, chemical, and food-grade tablet manufacturing operations. Engineered with D-type and B-type international tooling standards respectively, the GZPK-45/55 series accommodates round tablets up to 25 mm in diameter and irregular tablets up to 25 mm, making it the most versatile high-speed tablet press in its class. Every unit is constructed from pharmaceutical-grade stainless steel with a fully enclosed GMP-compliant compression compartment featuring transparent glass panels for real-time visual monitoring. The hardened turret surface ensures decades of wear-resistant operation, while the dual-compression roller architecture guarantees consistent tablet hardness and minimal weight variation across production batches exceeding 378,000 to 462,000 tablets per hour.
Key Features
- Automatic Tablet Weight Control System: Integrated online weight monitoring continuously measures tablet weight during production. Out-of-spec tablets are automatically rejected via a dedicated rejection channel, ensuring 100% batch compliance with pharmacopoeia standards and eliminating manual sampling bottlenecks.
- Dual Compression Roller Architecture: Each tablet undergoes twice-compression forming within a single turret rotation cycle. This unique mechanism provides superior density uniformity across the entire tablet, eliminating capping and lamination defects that plague single-compression machines at high speeds.
- Double Impeller Force Feeder: Proprietary force-feeding technology actively drives granules into die cavities with consistent pressure and fill depth. This dramatically improves powder flow characteristics for sticky, low-density, or poorly flowing formulations, ensuring filling precision within plus or minus 2% across 24-hour continuous operations.
- GMP-Compliant Fully Enclosed Design: The compression zone is entirely isolated behind transparent tempered glass panels, preventing cross-contamination between the product and the external environment. The stainless steel housing, hardened turret surface, and oil-proof sealing system meet the most stringent global pharmaceutical manufacturing standards including FDA 21 CFR Part 211 and EU GMP Annex 1.
- Automatic Central Lubrication System: A programmable oil and grease distribution network delivers precise lubrication to pressure rollers, punch guides, and cam tracks at user-defined intervals. This eliminates manual greasing errors, extends tooling service life by up to 40%, and prevents lubricant contamination of the product zone through sealed delivery channels.
- High-Performance PLC Control with HMI Touch Screen: The industrial-grade programmable logic controller governs all machine parameters including turret speed, main compression force, pre-compression force, filling depth, and ejection height. Operators configure production recipes through an intuitive touch-screen interface, with password-protected access levels for formulation data security and audit trail compliance.
- Quick-Change Tooling Compatibility: Both GZPK-45 (D-type) and GZPK-55 (B-type) platforms support TSM-type and EU-type standard tooling, enabling rapid product changeovers without specialized tooling inventory. Punches and dies can be swapped in under 45 minutes by a trained operator, minimizing downtime between production campaigns.

Applications
The GZPK-45/55 speed tablet press machine excels across a broad spectrum of tablet manufacturing applications. In the pharmaceutical industry, it compresses active pharmaceutical ingredients (APIs) with excipients into precise dosage forms including immediate-release, sustained-release, chewable, and effervescent tablets with weight variations below 1% relative standard deviation. For nutraceutical and dietary supplement manufacturers, the machine handles vitamin blends, mineral complexes, herbal extracts, and amino acid formulations at production speeds suitable for global distribution volumes. In the chemical sector, the robust 100 KN main compression force enables the tabletization of catalysts, water treatment chemicals, detergent tablets, and industrial intermediates that require high compaction pressure. Food and confectionery processors utilize the GZPK series for milk tablets, candy tablets, bouillon cubes, and effervescent beverage tablets, benefiting from the oil-proof, dust-proof, and noise-proof enclosure that maintains food-grade hygiene. The dual-size tablet capability (round and irregular shapes up to 25 mm) makes this speed tablet press machine particularly valuable for contract manufacturers serving multiple clients with diverse product portfolios.
