• Complete Equipment List for Large-Scale Rapeseed Oil Production Line（2）

  2026-04-13 14:53:47

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.

Equipment in each section operates linked to ensure the automation and efficiency of the whole process from rapeseed raw materials to qualified edible oil. The following is a detailed description of each equipment (including functions, specifications, functions, and adaptation to customer needs):

Oil pressing section：

The pretreated billet is pressed at high temperature to extract crude oil.

The equipment in this section directly determines the oil yield and crude oil quality. Large production lines all adopt continuous pressing, so there is no need for manual frequent feeding and cake discharge.

The specific equipment is as follows:

1. Continuous Steaming and Frying Pan

Function: continuously steaming and frying the billet after rolling, removing the excess water in the billet through high temperature (controlling the water content at 3-5%), at the same time, fully softening the grease in the billet, enhancing the fluidity, destroying the combination of grease and protein, facilitating the smooth seepage of grease during subsequent pressing, and maximizing the oil yield.

2. Large-Scale Screw Oil Press

Function: the main engine of the production line, through the high-speed rotation of the spiral shaft, generates high pressure (the pressure can reach 30-50MPa) and shear force on the blank after steaming and frying, and extrudes the grease in the blank to realize oil cake separation; Continuous production with oil yields up to 38-42% (adjusted according to rapeseed quality).

3. Crude Oil Filter

Function: The crude oil pressed by the oil press is preliminarily filtered to remove residue, impurities, colloids, etc. in the crude oil, so as to make the crude oil clear, avoid impurities from entering the subsequent refining section, block the refining equipment, and improve the refining efficiency at the same time.
