How to Prevent Oil Press Clogging: Practical Maintenance and Operation Tips

How to Prevent Clogging in Your Oil Press Machine – Practical Tips for Home and Small Workshop Users

If you're running a small-scale oil pressing operation at home or in a workshop, one of the most frustrating issues you’ll face is clogging—especially when it leads to motor strain, downtime, and wasted energy.

The Real Cost of Ignoring Clogging Issues

According to our service team’s data from over 500+ customer cases last year, machines that experience frequent clogging have an average of 40% higher electricity consumption and 3x more mechanical wear on key components like the screw shaft and pressure chamber. That’s not just inefficiency—it’s unnecessary cost.

But here’s the good news: with proper maintenance routines and smart usage habits, you can reduce clogging by up to 75%, extend your machine’s lifespan by 2–3 years, and save real money on both power and repairs.

Daily Cleaning Is Not Optional — It’s Essential

Most users clean only once a week—but we recommend daily wiping down the feeding chute and pressing chamber after each use. Even small residues from sesame, peanuts, or soybeans can harden overnight and cause jams during the next cycle.

Use a soft brush (like the one shown in Image 1) to remove residue from the inner walls of the press cavity. Don’t use metal tools—they scratch surfaces and create micro-pits where oil residue builds up faster.

Lubricate Smartly – Not Too Much, Not Too Little

The gear system and screw rod need lubrication every 2 weeks under normal use. Over-lubricating causes oil to seep into the material stream, while under-lubricating increases friction and heat buildup—which directly contributes to clogs.

We suggest using food-grade mineral oil or a specially formulated grease designed for high-pressure food machinery. Apply a thin film—not a thick layer—and wipe off any excess immediately.

Why One-Click Operation Matters More Than You Think

Many operators rush through the “one-click” start function without waiting for the system to stabilize. But if the motor starts before the oil pump reaches optimal pressure, it forces the screw to work harder—leading to overheating and blockages.

Wait 3–5 seconds after pressing the button before adding new material. This simple step reduces motor load by up to 30%, according to our internal testing. And yes—it does make a noticeable difference in how smoothly your machine runs.

Quick Diagnostic Steps When Clogging Occurs

If your machine suddenly stops or makes unusual noises:

1. Turn off the power immediately.
2. Check the feed hopper for foreign objects or hardened residue.
3. Inspect the pressing chamber for obstructions (see Image 3).
4. If no visible issue exists, run a short test cycle without material—this helps clear any residual oil film causing false resistance.

You don’t need to be an engineer to keep your machine running efficiently. With these practical tips—based on thousands of real-world cases—you’ll avoid costly breakdowns, lower your energy bills, and enjoy consistent performance.
