Oilseed pretreatment and pressing plant

Rapeseed (soybean) → vibrating screen → stone remover → magnetic separator → crusher → embryo rolling machine → steaming and frying pan

The rapeseed (soybean) is transported from the silo to the pre-pressing workshop through the scraper and elevator, and then sent to the cleaning screen for cleaning to remove large and small impurities, and then to the stone remover to remove stone impurities of similar size to the material, and then enter the magnetic separator to remove ferromagnetic impurities, and then sent to the crusher through the conveying equipment. After the soybeans are crushed by the crusher, they are sent to the embryo rolling machine by the conveying equipment. The rapeseed (soybean) is rolled into thin slices by the embryo rolling machine to facilitate the next steaming and frying process. In the steaming and frying process, the temperature and moisture of the material are adjusted by heating and humidification to make the material suitable for pressing, and then enter the pre-pressing process. In the screw pre-pressing machine, the material is gradually increased in pressure by the action of the pressing screw and the screw cage, so that the oil is squeezed out of the material. The crude oil containing residue is precipitated in the oil tank and then pumped into the leaf filter for filtration. The obtained crude oil is pumped into the crude oil temporary storage box and then sent to the refining workshop for refining. The oil residue from the filter is sent back to the oil press for re-pressing, and the pressed cake is transported to the leaching workshop

Introduction to main production equipment:

Cleaning process:

Use high-efficiency vibrating screen and new gravity stone remover to remove various impurities.

Crushing process:

Double roller crusher is used, which has high crushing efficiency and good effect.

Rolling process:

The rolling mill uses a double-roller rolling mill to roll rapeseed (soybean) of a certain particle size into thin sheets to facilitate steaming, frying and pressing.

Steaming and frying process:

A vertical steam-frying pan is used for steaming and frying, which moistens, heats and steams the raw material to make it more suitable for pressing.

Pre-pressing process:

The use of the most mature and advanced spiral pre-pressing machine in China has achieved good results in rapeseed (soybean) oil pressing. It has strong adaptability to oil materials, stable equipment operation and high efficiency.

Crude oil filtration process:

The crude oil is initially separated from the coarse oil residue by using an oil clarifier, and then the fine residue in the crude oil is filtered out by a vertical leaf filter to facilitate subsequent refining.
