Single‑drum Flavoring Line
Equipment Introduction
This production line is composed of an elevator, drum seasoning machine, oil sprayer and automatic powder‑spraying machine. Dried puffed food is delivered to the drum seasoning machine by the elevator. While the drum keeps rotating, the oil sprayer and automatic powder‑spraying machine supply oil and seasoning powder synchronously. Materials are thoroughly mixed inside the drum to finish seasoning processing.
The electrical control part of the production line adopts centralized control via a control cabinet. Drive motors requiring variable speed are equipped with stable and reliable variable‑frequency speed‑regulating systems, and the heating system is fitted with temperature control and display devices. Featuring reasonable structural design, high automation level, easy operation and small footprint, the production line can reduce energy consumption and is suitable for supporting food‑processing plant construction.

Installation, Operation and Commissioning
1. Place the production line in a well‑ventilated and dry area according to the layout drawing.
2. Adjust the anchor bolts of each piece of equipment to ensure stable placement, avoid uneven stress on all parts of the equipment, and guarantee normal operation.
3. It is recommended to install knife switches (or air circuit breakers) for each power supply circuit of the production line to isolate from mains power for convenient later‑stage maintenance. All electrical equipment shall be reliably grounded or zero‑connected, with grounding resistance no more than 4 Ω to ensure electrical safety.
4. Plug the control lines of each electrical device into the corresponding connectors of the control cabinet with firm connection to avoid loose contact. After confirming correct wiring, switch on the power supply and commission each device one by one.
5. No‑load commissioning of the feeding elevator:
5.1 Check the tightness of all connecting parts and retighten any loose positions.
5.2 Press the start button to activate the drive motor, observe the operation of all components and check for abnormal noise.
5.3 If the conveyor belt deviates, adjust the adjusting nuts above the belt to restore normal operation.
5.4 Upon completion of commissioning, press the stop button to shut down the drive motor.
6. No‑load commissioning of the drum seasoning machine:
6.1 Check all connecting components for damage or looseness.
6.2 Verify whether the drum height is appropriate. Adjust the anchor bolt height to realize matched connection between the drum and the feeding elevator.
6.3 Start the drive motor and adjust the motor speed to check the performance of the speed‑regulating system.
6.4 Inspect the operation of all components and confirm no abnormal noise occurs.
6.5 After commissioning, set the motor speed to zero and stop the drive motor.
7. No‑load commissioning of the automatic powder‑spraying machine:
7.1 Check the tightness of connecting parts and confirm that the feeding screw extends into the drum by a proper distance.
7.2 Start the drive motor, adjust the motor speed and check the operation of the speed‑regulating system.
7.3 Inspect component operation and confirm no abnormal noise.
7.4 After commissioning, set the motor speed to zero and shut down the drive motor.
8. No‑load commissioning of the oil sprayer:
8.1 Check the tightness of all connecting parts and confirm good sealing of oil pipelines.
8.2 Clean the oil tank and fill it with palm oil.
8.3 Turn on the heating knob and set the temperature to 80 ℃.
8.4 Start the oil‑pump drive motor, inspect component operation and check for abnormal noise.
8.5 Observe the spraying effect of the spray gun. Adjust the knobs of overflow valve and throttle valve to optimize spraying performance.
8.6 Fix the spray gun inside the drum after commissioning.
8.7 Upon completion of commissioning, turn off the heating knob and stop the drive motor.
9. Before formal production, start the drive motors of the drum seasoning machine and feeding elevator to deliver puffed food into the drum. Then start the drive motors of the automatic powder‑spraying machine and oil sprayer to supply oil and seasoning powder into the drum synchronously. After production, turn off the heating knob and all drive motors of equipment, cut off the power supply, and clean the equipment and production site.
10. Perform regular maintenance and inspection on the equipment to keep stable operation.
