Here is a detailed guide to installing and operating your small spray dryer. Whether you're new to this equipment or looking for a refresher, following these steps carefully will ensure safe and efficient operation.

Installation Instructions:

  1. Drying Chamber Installation: Hold the drying chamber with both hands and insert it into the fixing clamp. Secure it by tightening the lock nut. The chamber can be rotated within the clamp for proper positioning.
  2. Cyclone Separator Installation: Place the cyclone lock nut, sealing ring, and stainless steel gasket on the air outlet pipe of the cyclone separator. Insert it into the equipment’s air outlet and align the ports. Connect using a clamp and secure the lock nut once aligned.
  3. Connecting the Collection Bottle: Attach the collection bottle to the cyclone using a clamp.
  4. Connecting the Collection Tube: Connect the collection tube to the drying chamber with a clamp.
  5. Attaching the Spray Chamber: Mount the spray chamber onto the unit. Connect the 4mm air tube (for the needle) and the 6mm tube (for spraying).
  6. Peristaltic Pump Setup: Install the food-grade silicone tube on the peristaltic pump and connect it to the spray chamber inlet.

Operation Instructions:

To start the peristaltic pump, click “Open,” then “Start.” To stop, click “Stop” or use the automatic mode. In auto mode, the pump adjusts speed based on the outlet air temperature setting. You can toggle back to manual mode at any time.

Control Panel Functions:

  • Fan Control: Click the fan button (above) to start or stop the fan.
  • Needle Control: Use the black button above to start or stop the needle. Adjust the running frequency in the interface.
  • Air Compressor: Start or stop the compressor via the black button above.
  • Heater Control: The heater must be started after the fan. It automatically shuts off when the fan is turned off.

Settings & Adjustments:

To adjust settings, click the value box to bring up the numeric keypad. Clear the number with the CLR button, enter the desired value, and press ENTER to save. This applies to fan speed, needle frequency, and peristaltic pump feed rate.

Inlet Air Temperature Adjustment:

If there's a large fluctuation between the set value and the displayed temperature (more than 50°C), perform an automatic self-adjustment. Click the self-adjustment button (black area above) to begin. If needed, you can interrupt the process by clicking the end button.

Outlet Air Temperature Adjustment:

Similar to the inlet, if the display value differs from the set value by more than 50°C, initiate the self-adjustment. This ensures consistent performance during the drying process.
