oil extraction equipment

Brief description of seed oil extraction machine and its advantages:

1.Absorbing the world leading core oil extraction technology, design and develop a process which is efficient, economical and reliable.

2.Full automatic computer control system is adopted in oil extraction process, adjust automatically and operate stably.

3.Negative pressure technology is adopted in condensate system. Using the secondary steam which comes from the DTDC as the heat source of first evaporation, thus can maximum save the energy consumption.

4.Stainless steel heat exchange tubes and multistage baffling make the condenser have a high heat transfer efficiency, also the water consumption is low.

Main economic and technical parameters of seed oil extraction machine :

3Kg/T(6#solvent oil)

Crude oil moisture and volatile matter


Power consumption


Steam consumption

280Kg/T (0.8MPa)

meal moisture

10-13% (adjustable)

Residual solvent in meal

300PPM (qualified detonated experiment)

technology process of seed oil extraction machine:

1.Extraction process of edible oil extraction machine

The pre-pressed cake or flake, firstly enter into the sealed scraper blade to avoid the solvent gas escaping because of the section without screw blade in the sealed auger. Sunflower seeds enter into the box-chained loop type oil extraction machine counter-currenting with the solvent, the grease is extracted. Miscella condensity increase from 2% to more than 25%.

2.Evaporation process of edible oil extraction machine

Using the secondary steam desolventized from DTC desolventizer and produced by steam-jet pump to heat and evaporate micella in the first long-tube evaporator. Export temperature reaches to 58-62′ and condensity reaches to more than 65%.

3.Desolventizing process of edible oil extraction machine

Wet meals discharged from the bottom of oil extraction machine enter the top of DTDC and land on the predesolventizing trayers where thery are heated by the indirect steam, thus, some solvent in meal is evaporated and meal temperature is risen; Predesolventized meals land on predesolventizing trayers where they use the second steam in desolventizing trayers to predesolventize solvent from meal, then, meals enter desolventizing layers in which direct steam is injected.

4.Condensation recovery process of edible oil extraction machine

The oil extraction machine is equiped with a seperate condenser, 1st and 2nd evaporation share one condenser. Low and high temperature of solvent gas both from 1st and 2nd evaporation enter into the condenser after its neutralization, which greatly reduces the load of condenser and improves the efficiency of condensing. Stripping and analyzing share one condenser, the non-condensable gases from extractor and other condensers enter into the vent gas recovery system through the final condenser.
