The consequences of not detecting any faults of tablets and capsules during production could be the difference between patients receiving the correct and incorrect dose of their medicines.
As a result, manufacturers must ensure that these often critical items are all thoroughly checked before they leave the production facilities.
Viswill is an established manufacturer of visual inspection systems that have been specifically designed for use in the production of tablets and capsules. Throughout North America, Viswill is represented by DJA.
“The tablet detection system is the one that we started with,” explains Rusty Nelson, DJA VP and GM. “They’ve been making them for 20 years.
“It’s a high-quality machine, very fast, very accurate. Everybody always wants to evaluate. So, let’s say we run 100,000 tablets, they want to put those 100,000 back in and see what the reject rate was again and they find that it’s almost identical. The machine is accurate. But it requires a dedicated clean room.
“They’ve been doing it for many years, so they know what they’re doing.”
High-speed visual inspection machines for tablets
Viswill’s high-speed machines are capable of checking approximately 300,000 tablets an hour with precision, detect defects that are as thin as a human hair. The Japanese company’s machines all use advanced algorithms in their operations.
The TVIS-NS tablet visual inspection system is easy to use and clean, while requiring minimal maintenance. It uses cameras to not only check tablets, but also record and document its visual inspections.
The TVIS-NS uses 3D inspection to quickly spot chips on tablets or any marks that may compromise the integrity of coatings. Automated and customised options are available for the machines to allow flexibility with client requirements.
High-performance visual inspection equipment for capsules
For visual inspection of capsules, Viswill has designed the CVIS-NSE machine. This high-performance machine also uses cameras to ensure precision of inspections. A comprehensive visual assessment is performed, with the machines even able to detect any discolouring of capsules or foreign particles that may be present. Changeover is fast between batches, with full reports generated automatically for each cycle. Its intuitive touchscreen interface ensures simple operation and minimal training.
For manufacturers that need to handle both tablets and capsules, Viswill has the hybrid inspection system, TVIS-NSE. As with other machines designed by the company, it is a fully automated unit that uses cameras, 3D laser technology and state-of-the-art processing of images.
The TVIS-NSE is widely used for tablets and capsules that are both uncoated and coated, in addition to those that feature printed or engraved markings.
