Artificial Lyo-Vials With Durable Cakes for Automated Visual Inspection

The patent creates artificial lyophilized product cakes that replicate the visual characteristics and defect types of real lyophilized products. These artificial samples are made from durable materials that can withstand repeated handling and agitation without degrading. The artificial cakes include realistic defects such as low fill, high fill, collapsed cake, meltback, and foreign particles, allowing AVI systems to be trained and qualified with indefinite reuse, eliminating the need for frequent sample replacement while maintaining inspection accuracy.

The artificial lyophilized product cakes provide a reusable alternative to manufacturing new real samples repeatedly. Once the artificial samples are created with various defect types, they can be used indefinitely for AVI system testing, training, and qualification. This eliminates the continuous cycle of manufacturing new samples, reducing both manufacturing costs and development time while ensuring consistent sample availability for reliable system testing.

The artificial lyophilized product cakes are manufactured using simplified processes that directly create the desired defect characteristics without requiring complex lyophilization cycles. The artificial cakes can be produced with embedded defects such as low fill, high fill, collapsed cake, meltback, and foreign particles through straightforward manufacturing techniques. This reduces manufacturing complexity and cost while maintaining the ability to produce realistic defect samples for comprehensive AVI system training and qualification.
