Soybean processing technology

• production of high protein feed component
• production of vegetable oil

• SOYBEAN OIL
• SOYBEAN PRESSED CAKE (oil content 7 … 8%)
  (urease: 0.05 … 0.2 pH)

• soybeans, peeled soybeans – min 12 t/day

Soybeans are cleaned on separators in a mill mode:

• light and heavy impurities are removed
• if necessary divided into fractions
• the content of impurities is not more than 3%

To optimize the extrusion and pressing processes, soybeans are dried immediately before processing.

• Optimum moisture content of soybeans (for maximum oil yield): 8 … 9%.

• power line (workshop): min 160 kW
• production area: min 200 m²
• storage area of raw materials: min 250 m²
• floor storage area for oil cake: min 300 m²

• Floor height difference: 5 mm / m
• Indoor temperature: min 5 ° C

• Warehouse: from 250 m²

• Raw material cleaning: storage standards
• Dosing of raw materials: up to 8 … 10%

• Fiber removal: up to 5% by weight of raw materials
• Increase in protein specific gravity in oil cake: by 2 … 3%

• Raw material heating: 120 … 150 °C
• Decrease in urease activity: up to 0.05 … 0.2 pH
• Moisture decrease: by 1 … 3%

Oil cake production:

• protein: 40 … 48%
• oil content: up to 8%Oil production:
• solids residue content: up to 3%

• Decrease in temperature: after the final product had been discharged from the cooler, its temperature is 5 …10°C higher than the temperature in the shop

• Impurity reduction: removal of up to 90% of impurities

• Floor storage warehouse: from 300 m²

• Storage capacity: from 70 m³

• Determination of fat and protein content, moisture, urease activity
