Definition
What Is Continuous Granulation System?
A continuous granulation system is a process-section concept that combines controlled feeding, granulation and downstream handling for OSD manufacturing development.
A continuous granulation system is used for pharmaceutical powder processing when the project requires continuous feeding, wetting or granulation and downstream discharge or sizing. It is positioned as a process-section equipment solution and can be evaluated together with upstream and downstream process requirements.
Final equipment configuration and performance should be confirmed according to material characteristics, process requirements and technical evaluation.
Working principle
How Continuous Granulation System Works
Materials are metered continuously into the process, mixed or granulated under controlled conditions, then transferred to drying, cooling, milling or collection according to the process route.
The practical result depends on material behavior, selected model, operating parameters and how the equipment connects with upstream and downstream process steps.
Powders are metered continuously into the process
Liquid, melt or process energy is introduced according to the route
Granules are formed under controlled process parameters
Downstream drying, cooling, sizing or transfer is configured by project scope

Process output and capacity
Process Output & Capacity
A continuous granulation system is selected for continuous process development or production sections. Output depends on formulation, feed rate, liquid or melt addition, granulation mechanism and downstream handling.
Granule size depends on formulation, feed rate, liquid or melt conditions, screw or mixing configuration and downstream milling or sieving. Testing is recommended for target granule properties.
Capacity depends on process route, model selection, feeder range and downstream equipment. Catalogue data covers lab to production extrusion/granulation models, with exact throughput confirmed by evaluation.
- Process objective

Testing and evaluation
Continuous Granulation Process Evaluation
Technical evaluation is recommended because formulation, feed behavior, wetting, granule formation and downstream sizing determine the final process concept.
Formulation and feed
Confirm formulation type, feed rate, flowability and liquid or melt addition requirement.
Granule target
Define target granule properties, downstream drying or cooling and sizing expectations.
Process section scope
Confirm whether the customer needs a module, process section or configurable upstream and downstream interfaces.
Selection logic
When to Choose Continuous Granulation System
Choose continuous granulation
Best for: continuous process development or production section
When to consider: when stable metered feeding and continuous granule formation are required.
Use with downstream modules
Best for: drying, sizing, sieving and transfer integration
When to consider: when the granulation section must connect to defined upstream or downstream equipment.
Run technical evaluation
Best for: new formulations or uncertain process behavior
When to consider: when process parameters are not yet confirmed.
