• Complete Equipment List for Large-Scale Rapeseed Oil Production Line（1）

  2026-04-13 14:45:21

Large-scale rapeseed oil pressing production line (suitable for daily production capacity of 50-500 tons/day, meeting large-scale industrial production), is divided into four sections: pretreatment section, oil pressing section, refining section, finished product storage and filling section.

The equipment in each section operates linked to ensure the automation and high efficiency of the whole process from rapeseed raw materials to qualified edible oil. The following is a detailed description of each equipment (including function, specification and function, adapting to the needs customers):

Pretreatment section

Function: removing impurities, optimizing billets, improving efficiency for subsequent pressing and reducing equipment loss.

Pretreatment is the basis of large-scale production line, which directly affects the oil output rate and the service life of subsequent equipment. The complete set of equipment according to the process is as follows:

1. Vibrating Cleaning Sieve

Function: Carry out preliminary cleaning on raw rapeseed, remove large particle impurities such as straw, weeds, soil and broken leaves (removal rate ≥98%), and prevent impurities from entering subsequent equipment, causing equipment wear or affecting oil quality.

2. Specific Gravity Stone Remover

Function: Using the difference of specific gravity between rapeseed and sand and gravel, thoroughly separate heavy impurities such as sand and gravel and metal debris mixed in raw materials through wind force and vibration (stone removal rate ≥99%), protect the rolls of subsequent crushers, billet rollers and screws of oil press, and avoid equipment jamming and wear.

3. Magnetic Separator

Function: Remove the hidden iron impurities (such as iron nails, iron chips, iron wires, etc.) in the raw materials, prevent the iron impurities from entering the equipment such as crushing and rolling, avoid the wear and damage of key components such as rolls and screw pressing, and at the same time avoid the iron impurities mixed in the oil, which affects the safety of oil quality.

4. Rapeseed Crusher

Function: Crushing the clean rapeseed into uniform small particles (2-4 petals), breaking the shell of rapeseed, facilitating subsequent softening and rolling, increasing the contact area between the billet and the grease, and improving the subsequent oil yield.

5. Softening Pot

Function: Heating and tempering the crushed rapeseed (adding a small amount of water to control the moisture content of the billet at 10-12%), softening the billet, increasing plasticity, avoiding powder generation during subsequent billet rolling, reducing the wear of the billet rolling machine and ensuring uniform billet rolling.

6. Flaking Machine

Function: The softened rapeseed billet is pressed into a uniform, thin and tough billet (the thin billet can increase the oil seepage area), and at the same time, the cell structure of rapeseed is destroyed, so as to prepare for subsequent steaming, frying and pressing, which can increase the oil yield by 3-5%.
