The Ultimate Guide to Operating a Fully Automatic Bun Machine: From Startup to Finished Product (Pro Edition)

1. Pre-Production: The "Golden Ratio" & Preparation

Successful automation starts with standardized raw materials. The machine's performance depends heavily on the consistency of your dough and filling.

The 1:1 Dough Secret: We strongly recommend a 1:1 dough-to-water ratio. This specific ratio ensures the dough has the ideal elasticity to pass through the screw feeder without losing structural integrity.
The "Silky" Pre-Treatment: Before adding the dough, apply a thin layer of cooking oil to the inner walls of the hopper.

Benefit: This lubrication allows the dough to enter the machine smoothly and, more importantly, makes post-production cleaning effortless as the dough won't stick to the walls.

Do not start the dough and filling systems simultaneously. Follow this sequence to minimize waste:

Dough Supply First: Turn on the dough-feeding knob.
The "Empty Shell" Test: Let the machine produce 1-2 empty dough shells. This stabilizes the pressure in the dough tube and confirms the thickness is correct.
Start Filling: Once the dough shells are consistent, activate the filling system.

The Josen machine features independent frequency controls for dough, filling, and forming.

To Increase Filling Content: Keep the dough speed constant and increase the filling speed. The bun will become larger with a higher filling-to-dough ratio.
To Adjust Skin Thickness:

For thinner skin: Maintain dough speed while increasing filling speed.
For smaller buns: Proportionally decrease both dough and filling speeds, or increase the forming (cutter) frequency.

One machine can produce buns of various weights (e.g., from 30g sliders to 120g large buns).

Easy Mold Change: Simply replace the forming mold (dough outlet) to switch between different product weights. This modularity allows your production line to be highly versatile.

Cleaning efficiency is crucial for commercial operations. Our SUS304 Stainless Steel construction makes this process straightforward.

Step 1: Rapid Disassembly: Remove the dough tube and screw feeder. Due to the pre-lubrication (oil coating) mentioned earlier, the remaining dough will peel off easily.
Step 2: Water Rinse: Rinse the stainless steel components directly with water. The smooth surface ensures no residue is left behind.
Step 3: Maintenance: After drying, apply a drop of food-grade lubricant between the cutter blades to ensure "silky" operation for the next run.
