1. cGMP Design: 150 grit exterior finish, mirror finish on internal surfaces. The
system can meet GMP standard;
2. HEPA air filter: The air filter consists of primary stage, secondary stage and high
efficiency stage air filter and the air cleanness can reach 100,000
grade;
3. Automatic pneumatic sealing: two pneumatic cylinders lift the granulation bowl for sealing with
the top chamber; the inflated square rubber ring will seal the
bottom chamber to create a completely sealed granulation chamber;
4. Two-bag-filter-chamber system: The top bag filtering system has two chambers which work
alternately to avoid air pressure onto the filter bag. The product
rate can reach 99%.
5. Accurate air flow control: The exhaust fan is combined with Siemens inverter to accurately
control the air flow rate for achieving perfect fluidization.
6. Good working condition: The whole system is working under negative pressure, so there is
no powder leaking at all. Exhaust fan is equipped with silencer as
well as isolated installation, the noise is below 75 dB(A).
7. Safety measures: The whole system adopts following measure to 100 % make sure
safety during operation:
1) Function interlocked: All the function buttons in the control
panel are interlocked (only proper operation steps can run the
system) to prevent any mistakable operation to the machine.
2) Explosion proof design: Granulation chamber is equipment with
venting. When the pressure inside the chamber is getting higher
than the rated one (say 2 bar), the rupture membrane will break to
release the pressure.
3) Pressure monitoring: Pressure sensor is equipped to monitor
pressure change inside the granulation chamber. When pressure is
getting higher (especially when the bag filter is choked) and
positive pressure condition is formed, electrical heater and
exhaust fan will stop automatically and pressure release valve will
open.
