Coating Place developed its design of their modern fluid bed microencapsulation Wurster coating unit using Dr. Dale Wurster’s intellectual property and prototype equipment they purchased in 1976. Since that time, the team at Coating Place has advanced the design of their Wurster coating unit by developing proprietary fluidization plates and nozzles that set our facility apart. This technology, along with the feasibility and product development services, enable Coating Place to provide customers with the highest quality services available in the Wurster fluid bed coating industry. Coating material is sprayed concurrent to the flow of the process air using our proprietary nozzles while customized plates allow for linear scalability from research units to production units without costly testing needed. Coating Place is the only company with linear scalability recognized by the Food and Drug Administration (FDA).
With twenty highly advanced Wurster units between two facility locations, Coating Place is capable of handling any size project from 0.010 Kg to 800 Kg. Our proprietary linearly scalable Wurster fluidization plates come in a variety of sizes, allowing a product to move from research to production with minimal effort. Our Model 400 research unit can be fitted with a 2”, 4” or 6” plate, while our Model 900 research unit can handle 6”, 9” and 12” plates. Our Model 600 research unit is the most flexible with a range from the 2” through the 9” plates. This allows our Formulations department to create batches from 0.01 Kg through 60 Kg ensuring an option for any client’s project development needs.
Whether the project is moving to commercial production from research or through a technical transfer to our facility, our linear scalability makes it easy to move manufacturing into one of our Model 1800, 3200 or 4600 Wurster units. Our Model 1800 unit boasts a single proprietary spray nozzle and the ability to use a 12” or 18” fluidization plate. This unit is capable of producing batches from 5 Kg to 90 Kg based on the plate used for production. The Model 3200 Wurster unit is equipped with a 32” fluidization plate and 3 proprietary nozzles for coating capabilities with the ability to make 75 to 300 Kg batches. Our largest model Wurster unit, the Model 4600, is fitted with 7 proprietary nozzles and a 46” fluidization plate for batches of 150 to 800 Kg. This wide range of coating capabilities makes Coating Place the contract manufacturer for projects of any size. All of our Wurster units are engineered and constructed in-house to ensure the highest quality machine possible.
