- Weight (g) Display: Shows the set filling weight and real-time filling weight.
- Quantity (package) Display: Shows the count of filled packages.
- Indicator Lights: Displays working status (Stop, Weighing, Full, Discharge).
- Weight Adjustment Buttons: Use '+' and '-' to adjust the target weight. 'Weight Zeroing' button for calibration.
- Advanced Setting Buttons: 'Function' for advanced settings, 'Delete' for clearing entries, 'Back' for navigation.
- Speed & Confirmation Buttons: 'Confirm' for setting changes, 'Slow', 'Medium', 'Fast' for filling speed, 'Exit' from advanced settings.
- Operation Buttons: 'Start', 'Stop', 'Discharge Products', 'Emptying Products'.
3.3 Applicable and Non-Applicable Materials
The machine is designed for dry, mobile products. Understanding material compatibility is crucial for optimal performance.

Image: A table illustrating suitable materials like flour, coffee powder, glitter, granulated tea, plastics, and coffee beans, alongside unsuitable materials such as ultra-fine powder, sticky products, wet products, and oversized products, with explanations for their incompatibility.
Applicable Products: Dry, mobile products with particle sizes between 0.047-0.39 inches (1.2-10mm). Examples include spices, coffee beans, glitter, pet food, rice, and various granules.
Not Applicable Products:
- Products generating static electricity: Such as steel beads or ceramic beads, as they are difficult to flow into the weighing hopper.
- Ultra-fine powders: Like matcha powder, cocoa powder, or nano fine powder. These can stick to the inner wall of the vibration pan and weighing hopper, leading to inaccurate weighing and prolonged filling times.
- Sticky products: Such as gummy bears, which adhere to internal surfaces.
- Wet products: Can cause blockages and damage to the machine.
- Oversized products: Large pieces like corn flakes, tortilla chips, nuts in shell, or leaf-like tea. These can get blocked in the weighing hopper and are difficult to dispense.
4. Setup
- Unpacking: Carefully remove the machine and all accessories from the packaging. Retain packaging for future storage or transport.
- Placement: Position the machine on a stable, level, and clean surface. Ensure there is enough space for operation and material loading.
- Hopper Assembly: Place the stainless steel hopper securely onto the top of the machine. Ensure it is properly seated.
- Power Connection: Connect the power cord to the machine and then to a grounded electrical outlet.
- Foot Pedal Connection (Optional): If using the foot pedal, plug it into the designated port on the machine.
5. Operating Instructions
5.1 Basic Operation
- Power On: Turn on the main power switch. The LED display will illuminate.
- Zeroing: Before adding material, press the 'Weight Zeroing' button (part of section 4 in the control panel image) to ensure the machine is calibrated to zero.
- Set Target Weight: Use the '+' and '-' buttons (part of section 4 in the control panel image) to set your desired filling weight in grams. The set weight will be displayed on the 'Weight (g)' screen.
- Load Material: Pour the dry, free-flowing material into the hopper.
5.2 Filling Process

- Trigger Filling:
- Infrared Sensor Mode: Place your container directly under the discharge port. The infrared sensor will detect the container and initiate the filling process automatically.
- Foot Pedal Mode: Press the foot pedal once to start the filling process. Release the pedal when the desired amount is dispensed or when the machine automatically stops.

- Monitor Filling: The 'Weight (g)' display will show the real-time weight of the material being dispensed. The machine will automatically stop once the target weight is reached.
- Package Count: The 'Quantity (package)' display will increment by one after each successful fill.
- Stop/Empty: Use the 'Stop' button to pause operation or 'Emptying Products' to clear the machine.
5.3 Adjusting Filling Speed
You can adjust the filling speed to suit different materials and desired accuracy levels using the 'Slow', 'Medium', and 'Fast' buttons (part of section 6 in the control panel image).
- Slow: For higher precision with finer materials.
- Medium: General purpose filling.
- Fast: For quick dispensing of larger granules where slight variations are acceptable.
