Continuous CoaterHaving pioneered development of the first perforated, side vented coating pan, Thomas continues to elevate coating technology with the introduction of the Continuous Coater. By transforming the concept of film coating from a batch to a continuous process, the Continuous Coater improves uniformity, increases throughput and automates feed and discharge. The Continuous Coater utilizes a fully perforated pan, conditioned air, an exhaust plenum and spray guns. Unlike conventional coating pans, the Continuous Coater does not require loading and unloading. Instead, it works on a flow process where the product continuously enters the pan at one end and leaves at the opposite end fully coated. The thermodynamics of the coating process remain unchanged. |

Benefits of the Thomas Engineering Continuous Coater
- Process high volume products with greater throughput than successive batch operations - Loading, warm-up, unloading and cool down are concurrent with the coating process; eliminate "sub-batching" and also reduce material handling.
- Improved coating uniformity - Shallow bed provides more frequent presentation of tablets to the solution spray; improves color uniformity and overall elegance of finish.
- Gentle handling of tablets - Short residence time and shallow tablet bed reduce attrition.
- Automatic infeed gently introduces tablets to the bed on a steady basis - Weigh belt interface permits tablet loading automation with COMPU-COAT control.
- Ideal for high volume OTC, nutraceutical and soft gel processing.
- Solution delivery options permit choice of commercially available spray guns.
