Q & A

What industries commonly use the wet type granulator?

The wet type granulator is widely applied in industries such as pharmaceutical, foodstuffs, chemicals, and dairy.

What are the main functions of the wet type granulator?

The wet type granulator primarily functions in mixing, granulating, and producing wet granules for tablets and capsule granules.

How is the machine designed to ensure efficient product discharge?

The machine features an oblique azimuth for product discharge, which allows for a more efficient and controlled flow of the granules.

What is the purpose of the maintaining gate in the wet granulator?

The maintaining gate is provided to help users easily maintain and repair the machine, ensuring smooth operation and accessibility.

How is safety ensured when opening the pot cover of the granulator?

The pot cover can be opened manually and is auto-locked for safety during operation. The high-strength silica gel seal ensures safety by preventing leaks, and it is also food-grade for easy removal and cleaning.

What design feature prevents cross-contamination of products during operation?

The wet granulator combines pneumatic and mechanical seals for both the spindle drive part and the chopper, with a purge system of compressed air to prevent material leakage and cross-contamination.

What is the purpose of the frequency converter in the paddle motor?

The frequency converter in the paddle motor allows for adjustable speeds and helps in cleaning the paddle, as it can lift up to 50 millimeters for easier maintenance.

How does the system supply binder during the granulation process?

After mixing the product with the paddle, the spraying system provides binder through a pressure spray, offering a quick and effective way to add binder to the mixture.

What happens to the granules after granulation is finished?

Once the granulation process is complete, the discharging valve opens, and the granules are poured into the sizing machine for further processing, where oversized particles are homogenized.

What role does the PLC and HMI control system play in the wet granulator?

The PLC and HMI control system allows for the management of the granulation process, with 99 recipe parameters that can be stored and used for repeatable and reliable processing, while also enabling monitoring and different authority access.
