Hydraulic Oil Press

Presses oil from a batch of prepared seed or paste using hydraulic force. Vertical and horizontal designs with filter plates or press barrels.

Rating
Sized to seed or paste charge per batch (kg) and cycles per hour
Versions
Vertical press · Horizontal press · Filter plate or barrel type
Best for
Small oil workshops and specialty oil producers pressing sesame, walnut, cocoa or other high-value oils
  • Batch pressing without heat from friction, suited to aroma oils
  • Clear oil when pressed through filter plates
  • Simple mechanical design with few wearing parts
  • Vertical or horizontal layouts

Short answer: A hydraulic oil press puts a batch of prepared seed or paste under high pressure using a hydraulic cylinder, and the oil runs out through filter plates or the barrel wall. The configuration depends on how the seed is prepared, how large each batch is, the cycle time you can accept, and how the cake is taken out after pressing.

How it works

Prepared material, often roasted and ground seed or a warm paste, is loaded into a press barrel or stacked between filter plates, sometimes wrapped in filter cloth. A hydraulic pump drives a ram that pushes the material against a fixed head. Pressure rises gradually and is held for a set time while oil drains into a collecting tray. When oil flow slows, the pressure is released, the cake is pushed or lifted out, and the press is reloaded.

Because the material is pressed rather than sheared, there is little heat from friction. This is one reason hydraulic presses are used for sesame and other oils where aroma matters. The trade-off is batch operation, with loading and unloading time between charges. Output therefore depends as much on how quickly operators can load and empty the press as on the press itself, and several presses are often run side by side to keep a steady supply of oil.

Which configuration fits

Form Suits Watch out for
Vertical press Sesame oil workshops, small batches Manual loading; floor height
Horizontal press Larger charges, easier cake handling Larger footprint
Filter plate type Clear oil straight from pressing Cloths and plates need cleaning
Barrel type Pastes and finely ground seed Oil may need more settling

What we need from you to quote

  • Seed or nut type and how you prepare it (roasting, grinding, warming)
  • Batch size and how many batches per shift
  • Oil style and any reference sample
  • Expected output measured on seed input per day
  • How you plan to remove and use the cake
  • Power supply and floor height

Where it sits in a line

Seed is cleaned with oilseed cleaning equipment and roasted in an oilseed roaster. Crude oil goes to an edible oil filter before filling. It is one of the pressing options in a sesame oil production line; for continuous pressing see the screw oil press.

Common configurations

  1. Option A

    Vertical press

    material is loaded into a barrel or stacked between plates and pressed from below; compact and common for sesame oil.

  2. Option B

    Horizontal press

    pressing along a horizontal axis; easier loading and cake removal for larger charges.

  3. Option C

    Filter plate or barrel type

    plates with filter cloth give clearer oil; barrels suit pastes that are wrapped or contained.

Frequently asked questions

  1. Hydraulic press or screw press?

    A hydraulic press works in batches and generates little friction heat, which helps preserve aroma in sesame, walnut and similar oils. A screw press works continuously and suits larger volumes. Many small sesame oil workshops use hydraulic presses.

  2. Does the seed need roasting?

    For roasted sesame oil, yes. For cold-pressed oils, seed or paste is pressed without roasting, but it often still needs warming or conditioning to release oil well.

  3. How is the oil cleaned after pressing?

    Oil from a hydraulic press is usually fairly clear but still carries fine particles. Settling and a filter press or bag filter are normally used before filling.
