ZPTX Series Double-Press Rotary Tablet Press: GMP-Compliant Solution for Pharma, Nutra & Food Industries (Up to 120,000 Tablets/Hour)

Introduction
Pharmaceutical manufacturers grapple with cross-contamination risks and strict GMP compliance; nutraceutical producers struggle with uneven feeding of herbal powders; food processors need efficient solutions for chewable or effervescent tablets. If these pain points sound familiar, the ZPTX Series Double-Press Automatic Rotary Tablet Press is your answer. Engineered for continuous, precision compression of granular materials into round, engraved, irregular-shaped, and dual-color tablets, this series blends advanced technology, durable build quality, and customizable features to solve your production challenges—whether you’re in pharma, chemicals, food, or electronics.
Why the ZPTX Series Stands Out for Your Industry
For Pharmaceutical Manufacturers
GMP-compliant stainless steel design prevents cross-contamination, meeting FDA and EU regulatory requirements for drug production.
120KN max pressure (ZPTX 15/19/21) handles high-density formulations (e.g., veterinary drugs, mineral-based meds) without cracking.
Dust extraction system keeps the compression chamber clean, critical for maintaining drug purity.
For Nutraceutical & Herbal Brands
Optional forced feeding devices (closed/open) solve poor fluidity issues in herbal powders, ensuring consistent tablet weight.
Custom filling depth (up to 35mm) accommodates high-dose supplements, eliminating the need for multiple tablets per serving.
For Food & Confectionery Producers
Food-grade 0Cr18Ni9 stainless steel hoppers resist corrosion, suitable for chewable candies or effervescent tablets.
Low noise (≤70dB) operation keeps your workshop environment comfortable for long production shifts.
Core Features: Solving Your Production Pain Points
1. GMP-Compliant Hygiene to Avoid Cross-Contamination
Full Stainless Steel Enclosure: Outer cover and internal workbench use 0Cr18Ni9 stainless steel (GB/T 3280-2021 standard)—resists rust, maintains surface luster, and prevents material contamination. Fully aligns with GMP guidelines for pharma/food production.
Oil-Dust Isolation: Upper and lower punch molds have oil-dust rings. This blocks oil from touching raw materials, solving the common issue of oil contamination that ruins product quality.
2. Visibility & Accessibility to Reduce Downtime
Acrylic Inspection Windows: Real-time view of the tableting process lets operators spot anomalies (e.g., uneven filling) quickly—avoiding batches of defective tablets.
Full-Open Side Panels: Side panels open completely for easy cleaning, mold changes, or maintenance. Cuts downtime by 30% compared to machines with limited access.
3. Safe & Stable Operation to Protect Equipment & Products
Variable Frequency Drive (VFD): Danfoss inverter (model 132F0028) enables smooth speed adjustments (5-25 RPM). Reduces energy use by 15% and prevents sudden jolts that damage molds.
Overload Protection: Automatically shuts down if pressure exceeds safe limits (e.g., 120KN for ZPTX 15). Avoids equipment damage and defective tablets from over-compression.
4. Dust & Heat Management for Operator Safety
Built-In Dust Extraction: Removes fine particles from the compression chamber. Protects operators from inhaling harmful dust and keeps materials clean.
Sealed Transmission System: Transmission parts are enclosed in a bottom oil tank—isolated from the working area to prevent cross-contamination. Oil immersion also cools parts efficiently, extending service life.

Note: Max capacity uses smallest round tablet (Φ11mm) and 25 RPM. Output drops 15-20% for irregular-shaped or thick tablets (≥8mm).

Premium Build Quality: Durability You Can Trust
We use high-grade materials to ensure the ZPTX series runs reliably for years—even under continuous use:
Pressure Rollers: GCr15 bearing steel (GB/T 1222-1984) with HRC60-62 hardness—resists wear from high-pressure compression.
Main Drive Worm Gear: ZQSn10-1 tin bronze (GB/T 1176-1987) with HRC45-48 hardness—smooth transmission, low noise.
Feeder: ZQSn6-6-3 tin bronze with chrome plating—prevents material sticking and corrosion.
