1). Magnetic separation
The cylinder magnetic separator consists of shell, rotating door, magnetic core, etc. The magnetic core consists of distributing umbrella shape hat, magnetic ring, magnetic core cylinder. The raw materials get into the machine through the upper flange inlet, then through the distributing umbrella shape hat to make the materials fall down averagely, if there are iron materials inside the sunflower, the iron materials will be absorbed by the magnetic ring, to separate with sunflower. The cylinder magnetic separator has the advantages of no power, saving energy, easy maintenance and usage, etc. ( Sunflower Cake Solvent Extraction Line )
2). Cleaning Cleaning process is very important for pretreatment process. The bigger materials maybe will wedge into the equipments to block the raw materials, this will corrupt the equipments which will shorten the using life and lower down the working efficiency. Therefore, it needs cleaning screen to remove the big impurities, using magnetic separator to remove the metal things.
The cleaning sieve always use vibrating sieve, it means the screen is taking advance and return movement in the working time, the cleaning efficiency is very high and works reliable. The structure consists of feeding parts, screen body, screen surface, screen cleaning parts, vibrating parts, drying parts, dust catching parts, etc.
3). Specific-gravity Stoner This machine is used to separate the side by side stone from the sunflower seed, according to the different specific gravity and suspending speed, the side by side stone will fall at bottom, and under the function of stoning plates, the stone moves to the stone discharging port. While the soybean seed at the upper floor will flow to the soybean discharging port under the self-supporting effect. The machine has the features of strict structure, good dustpoof effect, and high stoning ratio, etc.
4). Crushing The purpose of crushing is to crush the sunflower seed into small granules, which will be easy for flaking process to destroy the oils and fats cells, which can provides conditions for high oil pressing efficiency. Assembled with alloy tooth roller which using life is one time longer than common rollers. The crusher can crush the corn germ averagely, also it has automatic roller control system, also it has good sealing effect. ( Sunflower Cake Solvent Extraction Line )
5). Conditioning Adopts layer type conditioning pot, the max distance between mixing wing and bottom of pot is 5mm for each layer, which avoid the nonuniform of raw materials. The whole pot is wholly sealed to keep the max humidity of the space of raw materials, to reach the best flaking effect and reduce the powder degree.
6). Flaking The purpose of flaking is to destroy the sunflower’s cell tissue which can make the oil separated smoothly. Also the flaking machine assembles alloy roller which using life is 1 time longer than common roller and also assembles automatic hydraulic roller tightening system to ensure the average thickness of flakes(≤0.3mm), the whole machine is sealed well.
7). Prepressing Since sunflower seeds are a kind of high oil content oilseeds, so we usually adopts prepressing first then solvent extraction method to get the oil out maximumlly. The prepressing methos can get 70% oil out, the oil residue in cake is about 15-20%. Adopts the prepressing process can meets different customer's needs about pressed sunflower oil and extraction sunflower oil, also the low fat meal.

---Process Description: 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. 2). Desolventizing Procedure of Sunflower Cake Solvent Extraction Line: 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 pre-desolventized 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.
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.
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.
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.
4). Solvent Condensation and Water Separation Procedure of Sunflower Cake Solvent Extraction Line: The liquor condensate that from evaporation condenser, energy 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 energy saver condenser, the energy saver’s liquor condensate and first evaporation shell pass’s liquor condensate get into the water segregator directly. The free gas of energy 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.
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.
4). 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.
---Adopting micro negative pressure process, save steam and reduce energy consumption. ---The secondary steam in the condensed water tank can be used for waste water preheating, reduce the steam consumption.
---Mixed oil adopts two levels process in removing impurity, dense mixed oil firstly into primary rotary liquid separator to remove larger particles, and then enter the secondary rotary liquid separator to remove impurity. After rotating liquid separation, the mixed oil nearly without solid impurities. After separation, the cleanermixed oil into the mixture oil staging tank for further precipitation, the bottom sediment of the mixing tank back into the extractor regularly by slag pump. Two process filter of the mixed oil and the use of negative pressure evaporation process, greatly reduce fouling in evaporation system, and evaporation system cleaning cycle can be extended. ---Collection all the steam in the extraction workshop and pump into the boiler room for secondary use, effective utilize the waste heat, saving workshop production water.
