Product Overview

Precision rotary compression for pharmaceutical-grade tablets

The ZP Series Rotary Tablet Press Machine represents state-of-the-art tablet compression technology designed to meet the stringent requirements of modern pharmaceutical manufacturing. Our fully automated rotary presses integrate powder feeding, pre-compression, main compression, and tablet ejection into a seamless, high-throughput workflow.

With production capacities ranging from 50,000 to 400,000 tablets per hour across 5 to 55 stations, our equipment serves both R&D laboratories and large-scale production facilities. The dual-layer servo-driven feeder ensures ±1-2% weight variation, critical for maintaining dosage uniformity per USP <905> and EP 2.9.40 standards.

Constructed with 316L stainless steel punch tips and hardened steel die tables with Ra ≤ 0.4 μm surface finish, our machines meet cGMP, CE, and FDA 21 CFR Part 11 requirements. The 10-inch touch-screen HMI allows operators to switch between tablet sizes (6-25mm diameter) in under 30 minutes, with pre-set compression recipes stored for instant recall.

  • 15+ years of tablet press manufacturing expertise
  • Installed in 30+ countries worldwide
  • IQ/OQ/PQ validation documentation included
  • Custom punch tooling and die configurations available

How It Works

5-step rotary compression cycle for precise tablet formation

1

Powder Feeding

Die table rotates under the feed frame where dual-layer servo-driven feeders distribute granules evenly into each die cavity. Adjustable feed blade speed ensures uniform fill depth for consistent tablet weight.

2

Pre-Compression

Upper and lower punches enter the die cavity to apply pre-compression force (adjustable 10-50 kN), expelling air from the powder bed and forming a preliminary compact. This prevents lamination and capping defects.

3

Main Compression

The main compression rolls apply final tableting force (up to 150 kN), compressing the tablet to target hardness. Closed-loop servo force control maintains ±1% accuracy across all stations simultaneously.

4

Tablet Ejection

Lower punches rise to eject tablets from the die cavity onto the take-off blade. An anti-sticking film on the punch faces prevents adherence. Scrapers keep punch heads clean for consistent compression.

5

Quality Control & Discharge

Optional in-line metal detectors and weight checkers inspect 100% of tablets. Under/over-weight tablets and those with metallic foreign matter are automatically rejected. Output rates up to 400,000 tablets/hour.

What is the production capacity range of YohoAI ZP series tablet presses?

YohoAI ZP series rotary tablet presses range from 5 to 55 stations, producing 50,000 to 400,000 tablets per hour depending on model. The ZP-19 produces up to 150,000/hr, the ZP-35 up to 280,000/hr, and the ZP-55 up to 400,000/hr at maximum speed.

What tablet sizes can the ZP series tablet press produce?

The ZP series supports tablet diameters from 6 mm to 25 mm across B, BB, and D punch configurations. Turret changeover between tablet sizes takes under 30 minutes with all compression recipes pre-stored and instantly recalled from the 10-inch HMI touch screen.

Do YohoAI tablet presses come with FAT and IQ/OQ/PQ validation documentation?

Yes. Every machine ships with Factory Acceptance Test (FAT) protocols, IQ/OQ/PQ validation documentation templates, EN 10204 3.1/3.2 material certificates for all contact parts, and a complete operation and maintenance manual covering installation, commissioning, and routine operation.

What are the compression force specifications for the ZP series?

Maximum compression force ranges from 80 kN (ZP-5 entry model) to 150 kN (ZP-55 high-force model). Force control accuracy is maintained at +/-1% via closed-loop servo feedback on both the pre-compression and main compression rolls, ensuring consistent tablet hardness across all 35 stations simultaneously.

How much does a YohoAI rotary tablet press cost?

Pricing for YohoAI ZP series rotary tablet presses typically ranges from USD 15,000 to USD 95,000 depending on station count and configuration. YohoAI equipment is priced 30-40% below comparable European brands such as Fette, Korsch, and IMA, while offering the same quality, performance, and regulatory compliance.

What is the typical lead time for a ZP series tablet press?

Standard configurations typically ship within 30 to 60 days from confirmed purchase order. Custom configurations with non-standard station counts or optional upgrades may require additional lead time. Contact the YohoAI engineering team for a project-specific delivery schedule.

What certifications do YohoAI ZP tablet presses hold?

YohoAI ZP series presses are CE certified, cGMP compliant, FDA 21 CFR Part 11 compliant, and ISO 9001:2015 certified. They are designed for pharmaceutical production in the US, EU, WHO-prequalified, and other international markets requiring these regulatory standards.

Which ZP model is right for my production scale?

The ZP-5 (5 stations, 50,000 tablets/hr max) suits R&D and pilot batches. The ZP-19 (19 stations, 150,000/hr) handles small-scale commercial production. The ZP-35 (35 stations, 280,000/hr) is the best seller for mid-to-large-scale facilities. The ZP-55 (55 stations, 400,000/hr) serves high-volume production plants.

How precise is the weight control on the ZP series tablet press?

The dual-layer servo-driven feeder achieves +/-1-2% weight variation per USP uniformity of dosage units standards. With the optional on-line weighbridge system, weight variation is reduced to +/-0.5%, ensuring tight dosage uniformity for active pharmaceutical ingredients across all 35 stations.

How quickly can I change over to a different tablet product on the ZP series?

Complete product changeover takes under 30 minutes thanks to tool-free punch and die removal and pre-set compression recipes stored on the HMI. The quick-release punch system allows operators to switch between different tablet sizes and shapes without requiring tools or lengthy revalidation.
