Why this crop is different

Crushing Canola

Canola is a high-oil seed, so most of the value comes out at the press. Running two presses side by side lets a mill crush more seed in a day without changing the rest of the line, and the oil from both is sifted, settled and filtered together before it goes on to storage and refining.

  • Canola is cleaned and destoned, cracked, separated from its husk, and stored, before it goes through the cooker on its way to the presses.
  • Tell us your daily tonnage when you enquire. It decides how many presses the line needs.

How a canola oil line works

Follow the seed from left to right. The numbers on the drawing match the steps below it, and every machine is explained in plain words.

Canola is cleaned, cracked and cooked, then two presses work side by side from one shared feed. The oil is filtered once and goes on to storage and refining.

The line, step by step

Clean the seed

Seed arrives from the field with dust, straw and stones in it. All of that is taken out first, because it wears the press and spoils the oil.

  1. 1
    Seed cleaner

    Shakes the seed over screens to take out dust, straw and anything larger or smaller than the seed.

    Cyclone and blower: Sucks away the light dust and drops it in one place, keeping the air in the mill clean.

  2. 2
    Destoner

    Removes stones, which are the same size as seed but heavier. One stone can damage the press.

  3. 3
    Cracker

    Breaks the seed open between rollers, so the hard outer skin can come away from the soft kernel.

  4. 4
    Kernel and husk separator

    Shakes and blows the broken skins away from the kernels. Husk holds no oil, so it should not go to the press.

    Husk goes to husk processing

  5. 5
    Seed storage silo

    Holds clean seed ready for pressing. A rotary valve at the bottom lets it out at a steady rate.

Moved between machines by: Bucket elevator, Screw conveyor

Warm the seed

Warm, evenly moist seed releases its oil far more easily than cold seed.

  1. 6
    Boiler

    Makes the steam that heats the cooker.

  2. 7
    Seed cooker

    Warms and stirs the seed with steam. Warm seed gives up its oil far more easily, like warm butter compared with cold.

Squeeze out the oil

This is where seed becomes two products: oil, and a dry cake known as meal.

  1. 8
    Final press ×2

    Oil expeller · Double chamber · Optiflow 30

    The heart of the mill. A turning screw squeezes the seed harder and harder until the oil runs out through narrow gaps, leaving a dry cake.

Moved between machines by: Bucket elevator

Cool the cake

Optional

Cake leaves the press hot. A cooler brings it down before bagging so it stores well. Not every line needs this.

  1. 9
    Meal cooler

    A slowly turning drum with air drawn through it cools the warm meal, so it stores safely in bags.

Weigh and bag the meal

The meal is weighed into bags. It is valuable in its own right, usually as animal feed.

  1. 10
    Batch hopper and weighing machine ×3

    Holds the meal and weighs out each batch into a bag.

  2. 11
    Bagged meal

    The pressed seed, sold as animal feed or sent on for further processing.

Moved between machines by: Screw conveyor, Bucket elevator

Separate the oil from the solids

Oil leaves the press cloudy with bits of seed, called foots. These are sifted out and sent back to the press, and the oil moves on.

  1. 12
    Vibro sifter

    The oil from the press is cloudy with bits of seed, called foots. This vibrating screen lets the oil through and holds the bits back.

  2. 13
    Paver chain conveyor

    Carries the wet bits caught by the sifter back up, so they go through the press again and their oil is not wasted.

    Solids return to the press

  3. 14
    Settling oil tank

    The oil rests here while the finer particles sink to the bottom, and a slow stirrer keeps the tank even.

Moved between machines by: Screw conveyor, Pump

Filter the oil

The oil is pushed through filters until it runs clear, then stored.

  1. 15
    Filter press

    Forces the oil through cloth-covered plates. The last fine solids stay on the cloth and clear oil comes out.

  2. 16
    Filtered oil tank

    Stores the clear oil after filtering.

Moved between machines by: Pump

The oil ends here: To storage and refinery

What it earns

What a Canola line produces in a day

Set to canola at 42% oil, the figure we publish for this crop. The tonnage, the hours and the three prices are yours to change — the rates shown are examples, not a quotation.

Oil content varies by seed, variety and growing region, so the figure above is only a typical starting point. Enter the number from your own lab report or purchase contract if you have one.

Prices are example rates; replace them with your local market prices. Machine capacity is rated per 24 hours.
