Raw Materials for Processing

The line is adapted for processing various oilseeds

🌱

Soybean

Primary raw material for the production of full-fat meal and high-nutritional-value soy oil

🌻

Sunflower seed

Alternative raw material for the production of oil and protein-rich cake

🥜

Rapeseed

Raw material for producing quality rapeseed oil and protein cake

🌾

Other oilseeds

Flax, cotton, pumpkin and other oil crops for specialised production

Final Products

High-quality products with wide application

🍶

Soy oil

High-quality cold-pressed soy oil for human consumption, rich in omega fatty acids and vitamins

🥣

Full-fat soy meal

Extruded product rich in proteins and fats, ideal for animal feed with high energy value

🌰

Soy cake

By-product of pressing with high protein content, used as an animal feed supplement

Key Machines and Equipment

Detailed overview of each production line component

1

Extruder E-500

Twin-screw wet extruder for thermal treatment of soy

Capacity
400-500 kg/h
Motor power
55 kW
Temperature
130-150°C
Inlet Moisture
16-18%

Wet twin-screw extruder that heat-treats soybean under high pressure and temperature. The Extrusion Process destroys anti-nutritive factors (trypsin inhibitors, lectins), increases protein digestibility and enables easier oil pressing. The extruded product has a porous structure ideal for further processing.

2

Screw press for oil pressing

Continuous cold press for soy oil pressing

Capacity
300-400 kg/h
Power
30 kW
Oil Yield
12-16%
Residual in cake
6-8%

Screw press for continuous oil extraction from extruded soy material. The screw mechanism creates pressure that separates oil from the material, while the solid residue (cake) is expelled through the adjustable outlet. The system allows precise pressure adjustment for optimal oil extraction.

3

Rotary Counterflow Cooler

Cooling system for extruded product

Capacity
500-2000 kg/h
Power
2.2 kW
Outlet temp.
30-40°C
Cooling Time
8-10 min

Rotary Cooler with counterflow cooling system. Hot extruded material is cooled by controlled airflow, preventing moisture condensation and preserving product quality. Drum rotation ensures uniform cooling of the entire product mass.

Other Line Components

4

Soy hopper

Feed hopper with flow regulator for receiving and dosing raw soybean into the line. Capacity 500–1000 kg.

5

Screw conveyor

System of screw conveyors for moving material between different process stages. Enclosed system preventing losses.

6

Magnet separator

Magnetic separator for removing metal impurities from raw material before entry into the extruder, protecting equipment from damage.

7

Conditioning system

Addition of steam or water to adjust material moisture before extrusion (optimum moisture 16–18%).

8

Oil filter

Filter system for purifying pressed oil from fine particles and impurities, ensuring clean oil for packaging.

9

Electrical Control Panel

Centralised PLC system for control and monitoring of the complete line, with touch-screen panel and alarm system.
