3. Setup
3.1 Unpacking and Inspection
Carefully remove the machine from its plywood case packaging. Inspect all components for any signs of damage during transit. Report any damage to your supplier immediately.
3.2 Placement
Place the doughnut machine on a stable, level, and heat-resistant surface. Ensure there is sufficient clearance around the machine for ventilation and safe operation.
3.3 Electrical Connection
This doughnut maker has a high power requirement (up to 3100W or more) and does not come with a standard plug. For safety, it is recommended to connect the machine directly to a circuit breaker. A circuit breaker rated at 35A or higher is required. Consult a qualified electrician for proper installation.
3.4 Initial Cleaning
Before first use, thoroughly clean all food-contact surfaces, including the hopper, dispenser mechanism, molds, and oil tank, with warm soapy water. Rinse thoroughly and dry completely.
4. Operating Instructions
4.1 Filling the Oil Tank
Fill the inner oil tank (capacity 25L) with appropriate frying oil. Ensure the oil level is between the minimum and maximum fill lines. Never operate the machine without oil in the tank.
4.2 Powering On and Temperature Setting
- Ensure the machine is properly connected to power.
- Turn on the main power switch.
- Use the rotary button on the control panel to set the desired oil temperature. The machine's default temperature display is in Celsius.
- The maximum allowable temperature setting is 250°C. Do not exceed this limit.

4.3 Preparing Dough and Filling the Hopper
Prepare your doughnut dough according to your recipe. Pour the prepared dough into the 9L hopper of the machine.
4.4 Selecting and Installing Molds
The machine comes with three different molds for various donut shapes and sizes:
- Ring Shaped Donut Mold: For traditional ring donuts. Diameter: 1.97~3.54 inches (50~90mm).
- Flower Shaped Donut Mold: For flower-shaped donuts. Diameter: 1.97~3.54 inches (50~90mm).
- Ball Shaped Donut Mold: For ball-shaped donuts. Diameter: 1.18~1.97 inches (30~50mm).
Select the desired mold and securely attach it to the dispenser mechanism.

4.5 Adjusting Donut Thickness
The machine features a 3-gear adjustment mechanism to control the thickness (or size) of each dispensed donut. Adjust this setting according to your preference and the desired donut size.

4.6 Dispensing Doughnuts
Once the oil reaches the set temperature, manually operate the dripping lever to dispense dough into the hot oil. The machine can produce approximately 500 ring/flower shaped donuts per hour, or up to 2000 ball-shaped donuts per hour, depending on size and operator speed.
5. Maintenance
5.1 Daily Cleaning
After each use, ensure the machine is powered off and cooled down. Drain the oil from the tank using the drain hole at the bottom. Clean the oil tank, hopper, dispenser, and molds with warm soapy water. Rinse thoroughly and dry completely to prevent corrosion and maintain hygiene.
5.2 Regular Inspection
Periodically inspect all components for wear and tear. Check electrical connections for any signs of damage. Ensure all moving parts operate smoothly.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not power on. | No power supply; circuit breaker tripped; faulty wiring. | Check power connection and circuit breaker. If issues persist, consult a qualified electrician. |
| Oil not heating. | Temperature not set; heating element malfunction. | Ensure temperature is set correctly. If still not heating, contact support. |
| Doughnuts are inconsistent in size/shape. | Incorrect thickness adjustment; dough consistency issues; improper mold installation. | Adjust the 3-gear thickness setting. Ensure dough consistency is appropriate. Re-install mold securely. |
| Oil spills from tank. | Overfilling the oil tank. | Ensure oil level is within recommended limits. |
