Skip Costly Repairs & Keep Production Flowing: Essential Upkeep Tips for Your Soybean Oil Press Machine

Your soybean oil press machine is the backbone of your oil production—keeping it running smoothly isn't just a task, it's a way to avoid costly downtime and keep oil quality consistent. With simple, regular upkeep, you can extend its lifespan and cut down on repairs. Here's Henan Glory's go-to maintenance playbook:

1. Non-Negotiable Daily Cleanup

After every shift, tear down the press chamber to clear leftover soybean cake. Hardened cake buildup clogs the chamber, strains the motor, and risks bacterial contamination in future batches. Wipe the machine's exterior too—oil and dust buildup turns into a tough, grimy layer that's a hassle to remove later. If the press sits idle for over an hour, pull out the screw shaft to clear hidden cake scraps (this prevents jams when restarting).

2. Lubrication: Keep Parts Moving Smoothly

Key moving components depend on proper lubrication to avoid wear:

Screw shaft: Lubricate it at the start of every shift to prevent dry grinding damage.
Gearbox: Check the oil level every 50 operating hours; replace the oil (and inspect its quality) once a year.
Bearings & bushings: Lubricate them regularly, and clear clogged oil holes right away. Neglecting this leads to overheated bearings or seized parts—costly to fix and disruptive to production.

3. Read the Signs: Spot Issues Early

Your press machine gives clear warnings when something's off—learn to "listen and look":

Unusual noise: Shut down immediately (this could mean a metal fragment/stone in the chamber, or a loose fastener).
Cloudy oil: Likely from overly dry soybeans or low machine temperature (aim for 60-70℃—the exterior should feel warm to the touch).
Low pressing capacity/excess slag leakage: Check for worn screw shafts, misaligned press bars, or too much chamber pressure.

Address these small issues fast (e.g., replace worn parts) to keep oil quality high and avoid bigger breakdowns.

4. Proper Shutdown: Don't Just Flip the Switch

Shutting down correctly prevents buildup and damage:

1-2 minutes before powering off, close the feed plate to stop adding soybeans.
Reverse the screw shaft 2-3 times to widen the cake outlet gap—let all leftover slag/cake fully discharge.

Only then turn off the power switch.

5. Long-Term Storage: Prevent Rust & Damage

If the press will be idle for a while:

Disassemble key parts (screw shaft, press bars, cake outlet ring) and clean them thoroughly.
Coat parts with a thin layer of oil to prevent rust.
Store everything in a clean, dry area—so your press is clog-free and ready to run when production resumes.

Cottonseed oil processing plant

 

Cottonseed oil processing plant

 

Setting up a cottonseed oil processing plant is a good choice for you, if your area plants a lot of cotton. Besides the profit of cotton, you can also make a profit by selling cottonseed oil. Do you know what equipment are needed in cottonseed oil processing plant?

First of all, cleaning machines are needed in cottonseed oil processing plant, which are used to remove the impurities from cottonseeds, like stones, straw, etc.  

Secondly, cottonseed husking machine is used to remove the shells. Usually, disc huller is the best choice for cottonseed oil processing plant. 

Thirdly, the shell and cottonseed should be separated. The kernel and shell separating machine is needed in cottonseed oil processing plant.  

Next, the machines are similar with those machines used in other oil seeds processing plant. Flaking machine and cooking machine to make the cottonseed adjust into the best condition for pressing. 

And at last is the cottonseed oil press machine. The engineers of Henan Doing Company will provide the most suitable oil press machine based on the features of your raw materials.

 

Henan Doing Company is a professional cooking oil machine manufacturer. We design the machines by ourselves, manufacture them in our own factory, and our engineers can give you best guidance in installation. 

The Cottonseed oil processing machine is one kind of cooking oil processing plants, and it has own special features because of the feature of cottonseed. So you need tell us your raw materials characteristic, your needs and your budget, and then our project manager and engineers will give you the project quotation. Weclome to contact us!

Peanut Oil Manufacturing Process

Main machines of peanut oil manufacturing process

Peanut Cleaning

Screening machine, de-stone machine and magnetic separator are the common cleaning machine for pre-treatment of peanut in oil extraction plant. They are adopted to remove certain impurities such as sand, stone, and metal, so that to improve the oil yield and production efficiency, and reduce wear rate of accessories. The immature, mildewed and broken peanuts should also be separated by the grading screen, which can be used to produce second grade peanut oil or be sold separately.

Husking

Husking machine is needed to remove the shells.

Crushing

Groundnut can be pressed as whole seeds in peanut oil making machine. But after crushing and flaking by use of roll crusher and flaking machine, the oil yield can be significantly increased. During the crushing process, the red skin of peanuts can be separated by wind selector, and to be used as raw material for medicine and chemical industry.

Flaking

The flaking machine is ued to flake the fruits, so as to make the peanuts reach the beast state before being pressed.

Cooking / Steaming

Roasting temperature is the key factor to produce peanut oil with fragrance. Too low, the fragrance will be weak, too high, it is easy to burn. In most situation, 180℃~200℃ is suitable. In order to prevent over cooked, the seeds should be cooled immediately, and then be crushed in toothed roller crusher.

Oil Pressing Process

Screw type peanut oil making machine is used in this process. Pressing temperature: 135℃; Moisture content 1.5%~2%. The residual oil rate can be reduced to 2% with twice pressing process. The crude peanut oil will be filtered by plate and frame filter, and then be sent to the refining machine. The oilcakes can be further processed in solvent extraction workshop to extract the residue oil, or be sold to feed mill plant. (Read more about defatted peanut flour production.

Peanut Oil Refinery

In some cases, the expeller pressed oil is required to be refined to produce high quality edible oil.
