Bi Layer Tablet Press for R&D – SDL 2 PLC

Lab Press – SDL-2 is a High Tech Double Layer & Mono layer Rotary Tablet Press for R&D and small batch production. This Single sided R & D Double Layer Tablet Press fully conforms to GMP and the safety requirements, featuring versatility with a quick change of tooling. For the suitable adjustment during double – layer tablet development, fully independent weight, height and hardness system are used for both the first and second layer. The Turret is driven centrally by a motor and Reduction gear box. The turret speed is adjusted by A.C. frequency drive. It’s available in Regular Model D’ Tooling or B’ Tooling, Multi Tooling – D+B Tooling or D+B+BB

SHAKTI Lab Press Control System Overview

Tablet Press Control System works force based press control system that utilizes feedback of measured compression peak force value to continuously adjust die fill level and thus compression force. It establishes and maintains target compression force feed back control scheme. The press control system automatically rejects tablets that fall outside of the designated compression force limits. HMI – PLC system provide features like

  • Touch Panel function for hassle free operation
  • Recipe Management covers following information
    • Recipe number ( Automatic Generation in sequence )
    • Recipe code
    • Tablet Parameters like
      • Product Name
      • Product Code
      • Product Size
      • Product Shape
      • Product Weight
      • Product Thickness
      • Product Hardness
    • Machine Parameter like
      • Machine Speed RPM
      • Feeder Speed RPM
      • Applied Pressure
      • Die fill depth
    • Control Parameters like
      • Target Compression force limit
      • Die fill control Upper / Lower limit
      • Tablet Rejection Upper / Lower Limit
  • Batch Management cover additional parameters like
    • Operator Code
    • Batch Start Time
    • Batch Size in Nos. of Tablet
  • Load cell software calibration
  • Advance sensor diagnostic
