Brief description

Expected benefits

1

Comprehensive recovery and application of sensible heat of quenching and conditioning tower

Application of new pillow-shaped heat exchange plate, high efficiency use and recovery of hot water heat for preheating raw materials, saving steam

Steam saving of 7 kg/t (for soy oil production)

2

Comprehensive recovery and application of sensible heat in cold and dry box.

Hot air from the outside of the cold dryer is used to heat the cold air from the inlet

Steam saving of 2~3 kg/t (for soy oil production)

3

Energy-saving applications of extruder.

The new generation of energy-saving extrusion machine, optimize the expansion coefficient, effectively reduce tons of material steam consumption, improve the extrusion effect

Steam saving of ~3 kg/t (for soy oil production)

4

Comprehensive recovery and application of sensible heat in evaporator and stripper.

Recovery of the sensible enthalpy of the hot air exhausted from the steamer and stripper to produce hot water for recycling

Steam saving of 5~8 kg/t and increase of electricity consumption~ KW (for soy oil production)

5

Vacuum leaching system.

Change the leaching vacuum method

Steam saving of 1~12 kg/t (for soy oil production)

6

Energy-saving vapor extraction tower.

Valve plate stripper structure, energy saving, low residual solution, more stable

Steam saving of 1~12 kg/t ~4kg/t;

solvent residual 50~20 ppm (for soy oil production)

7

Low temperature absorption system for exhaust gas.

Low temperature water to make the absorption tower temperature down to about 15 ℃

75% reduction of solvent emission;

reduction of a solvent consumption

8

Other sensible heat and absorption applications.

Secondary vapor utilization in steam extraction tower; water-water heat exchange in cooking tank; oil-oil heat exchange

Steam saving of 2~8 kg/t (for soy oil production)

Total

Average annual steam savings of ~25kg/t;

average annual solvent savings of ~ 200g/t
