Pressing for Oil
1. Turn on heating switch and wait for 25 minutes; extend the
waiting time appropriately during the cold seasons (never turn
it off during the oil pressing process).
2. Put dry ingredients into the hopper.
3. Press the “Pressing” switch and begin pressing oil.
4. After oil pressing ends, hold the “Cleaning” switch for 20 sec-
onds; it will be easier to remove the screw and then clean. It
is crucial to press the “Cleaning” button before the machine
cools. If the cleaning switch has not been pressed, after the
chamber becomes cold the residual slag hardens and the
pressing rod will become blocked.
Note: In case of power outage during the process, please turn
off the start switch and unplug power plug. Once power is recon-
nected, turn on the heating switch for at least 30 minutes before
continuing the press process.
Common Issues in Pressing
When pressing, any of the following can cause mistakes during the
process and lead to poor oil flow, or low quality oil:
• Raw materials have been stir-fried.
• Raw materials are overcooked (except camellia seeds).
• Raw materials are allowed to cool before pressing.
• Raw materials have been exposed to sunlight (exceptions for
peanuts and camellia seeds).
• Raw materials are overly wet.
• The machine is not properly heated up.
• Heating of raw materials is done with an induction cooker, light
wave stove, or electric radiant cooker.
• Freezer or refrigerator is used for storage of raw materials.
• Usage location is particularly dry.
• If oil and residue splash out at the same time in slag notch, this
may be because raw materials contain too much water. It
may also be associated with unsmooth incoming material or
slow pressing.
