---Process Description of equipment for oil extraction:
1). Solvent Extraction Procedure
The sunflower meal gets into the extractor through feeding scraper, the materials

run a circle from the feed inlet to discharge outlet in the extractor.

Spraying the extruded rice bran with the concentrate diminishing miscella

between the feed inlet to discharge outlet. Then before getting into the drain

off section, spraying again with fresh solvent, the drained wet meal discharges

into the wet meal scraper from the extractor’s discharge grid through kick-out device.

The concentrated miscella gets into the two-stage hydrocyclone from the pump,

to remove the powder impurities, finally get into the miscella tank.

This is preparation for oil press machine and cold press oil machine.

2). Desolventizing Procedure
The solvent contain wet meal that from the extractor are sent to the

DTDC desolventizer’s pre-desolventizing layer by scraper through air locker,

the bottom is heated by indirect steam to remove part of solvent;

then the predesolventized wet meal get into the desolventizing layer,

there are automatic control on the desolventizing layer to keep certain

thickness of materials, then the bottom gets into the direct steam to remove

all the solvent, at same time some steam condense in the meal,

the moisture content of meal will sectional rise after sunflower oil production line.

The desolventized meal falls onto the drying layer quantitative through rotary valve,

the drying layer keeps certain materials level, then process the drying procedure,

after drying get into the cooling layer to lower down the temperature,

finally discharge the finished meal through automatic flow controlling gate,

then though the scraper to transport the meal to warehouse for oil press machine

and cold press oil machine.

3). Evaporation Procedure
The miscella gets into the first long tube evaporation pass from the miscella tank,

the evaporated solvent gets into the evaporation condenser through separation

chamber, there are liquid level controlling device on the separation chamber’s outlet

pipeline to keep the liquid seal, the miscella that after first evaporation concentration

gets into the second long tube evaporator for evaporating process.

The shell pas is heated by indirect steam, the evaporated solvent vapor gets into

evaporation condenser through separation chamber, there are liquid level controlling

device on the separation chamber’s outlet pipeline to keep the liquid seal.

The miscella gets into the stripping tower’s disks from the top of the tower,

then fall down layer by layer, meanwhile jet direct steam from the bottom of

tower to remove the residue solvent of sunflower oil production line.

The top exit connects evaporation condenser, the high vacuum jet pump

keep the stripping tower working at negative pressure condition,

also there are liquid level controlling device in the bottom of stripping tower to

keep the liquid seal and steady flow quantity of product oil,

the crude oil are extracted out from the bottom of tower through

extraction pump, after cooling then get into crude oil tank for

sunflower seeds oil press machine.

4). Solvent Condensation and Water Separation Procedure
The liquor condensate that from evaporation condenser, enerLD saver

condenser and steam stripping condenser is collected together then

through recovery pump to inject them into water segregator.

The end condensed steam enter into the enerLD saver condenser,

the enerLD saver’s liquor condensate and first evaporation shell

pass’s liquor condensate get into the water segregator directly.

The free gas of enerLD saver condenser,tripping condenser, water segregator

and solvent library together enter into the final condenser, the end steam from

final condenser is absorbed by paraffin recovery device of oil press machine

and cold press oil machine.

The solvent phase of water segregator flows into solvent library for partial recycling,

the water phase discharged into steam tank, the direct steam gets into the steam tank

from the bottom to evaporate residue solvent, after this the water phase

discharged into water seal tank.

5). Tail Gas Absorption Procedure
The non condensed vapor from extraction evaporator, DT evaporator, oil stripper,

cooking pot, water segregator and underground solvent tank, get into the final condenser

for recovering the solvent, the non condensed vapor from the final condenser gets into

the mineral oil recovery device, the free gas are discharged into air through fire barrier.
