Top 10 Questions for Pharmaceutical Manufacturing Machine Operator Interview

1. Explain the process of tablet manufacturing on a rotary tablet press.

The process of tablet manufacturing on a rotary tablet press involves several key steps:

• Blending: Raw materials, including active pharmaceutical ingredients (APIs) and excipients, are blended to ensure uniform distribution.
• Granulation: The blended materials are moistened and granulated to form small, porous granules that improve flowability and compressibility.
• Drying: The granules are dried to remove moisture and achieve the desired particle size and moisture content.
• Lubrication: Lubricants are added to the granules to reduce friction during compression and improve tablet ejection from the press.
• Compression: The lubricated granules are fed into the rotary tablet press, where they are compressed using punches and dies to form tablets.
• Coating: Tablets may be coated with various materials to improve taste, appearance, and solubility.

2. What are the critical parameters that need to be monitored and controlled during tablet manufacturing?

Quality Control Parameters

• API content
• Tablet weight and hardness
• Tablet dimensions
