Description

Designed for high-volume production in the pharmaceutical and nutraceutical industries, the Stokes Model 560 stands out as a high-speed, single-sided tablet press machine. It boasts a unique configuration with two pre-compression stations, simplifying the process of creating bi-layer tablets, and features a detachable turret to maximize both flexibility and ease of cleaning. Equipped with up to 61 punches, this machine demonstrates impressive productivity, capable of manufacturing as many as 292,800 tablets per hour (BB-61) while accommodating a maximum tablet size of 25 mm (D-41). The Model 560 is renowned for its precise weight control, which guarantees uniform tablet quality. Additionally, its user-friendly interface, coupled with advanced safety features, makes it an optimal choice for handling demanding high-volume production needs.  

Main Benefits

  • Colored Lights in Press Frame Doors for Status Updates: The colored lights provide instant status updates of the tablet press, facilitating quick responses to operational conditions. This feature enhances monitoring efficiency and helps in maintaining a smooth production flow.

  • Enhanced Lighting System for Improved Clarity: The lighting system illuminates both the top and bottom sections, enhancing clarity and visibility during operation. This helps in monitoring and managing the production process more effectively.

  • Capability for Dual Pre-Compression and Bi-Layer Production: Each of the three compression stations can handle dual pre-compression and bi-layer production, with a maximum pressure of 100 kN. This flexibility allows for a wider range of tablet types and complexities, catering to diverse production needs.

  • Uniform Parts Across Compression Stations: The use of uniform parts across all three 10-ton compression stations simplifies the process of ordering replacements and managing spare parts inventory. This standardization leads to cost savings and easier maintenance.

  • OSHA Standards Compliance with Integrated Safety Mechanisms: Compliance with OSHA standards through safety mechanisms ensures a safe working environment, reducing the risk of accidents and meeting regulatory requirements.

  • Butterfly Valve on Hopper to Reduce Product Waste: The butterfly valve minimizes product waste by controlling the flow of powder into the machine. This efficient use of materials leads to cost savings and more sustainable production practices.

  • Dust Collection Mechanisms with Scraper: The dust collection system for both upper and lower die tablets, along with a scraper, maintains a clean operating environment. This reduces the need for frequent cleaning and ensures a hygienic production process.

  • Servo Motors for Automated Adjustments: The servo motors enable fully automated adjustments for lower rolls and fill cams, with a maximum fill depth of 19 mm. This feature allows for precise control over tablet size and density, accommodating a wider range of production specifications.

  • Robust Four-Pillar Design with Upper Doors: This design ensures operational stability and significantly reduces vibrations, leading to quieter machine performance. It provides a stable environment for precision tablet compression and prolongs the machine’s lifespan.

  • Spacious Hopper Entrance for Better Flow with Challenging Formulations: The larger hopper entrance facilitates the smooth flow of even difficult-to-handle formulations, enhancing the machine’s versatility and reducing potential disruptions in production.

  • Sealed Roller Bearings to Prevent Oil Leakage: The sealed bearings prevent oil from leaking onto the pressure rolls. This maintains a cleaner production area, reduces the risk of contamination, and minimizes maintenance requirements.

  • Dual-Level, Three-Paddle Feeder System: This feeder system effectively directs material into die bores, boosting production efficiency. It ensures a consistent flow of materials, leading to uniform tablet sizes and shapes and reducing downtime caused by material blockages.

  • Automatic Lubrication System for Increased Longevity: This system ensures consistent and proper lubrication of tooling and machine parts, reducing wear and tear. It extends the life of the machine components, saving costs on repairs and replacements in the long run.

  • Enhanced Visibility with Quadruple LED Lighting: The LED lighting significantly improves visibility in the compression area, aiding in both production and cleaning. This reduces the risk of errors during tablet production and makes it easier to maintain a clean and safe working environment.
