Pretreatment Process description

Magnetic separation
The drum magnetic separator is made up of the shell, magnetic core, and other parts. The magnetic core is composed of a shunt umbrella cap, magnetic ring, and magnetic core cylinder. The oil seed flows in through the upper flange opening and is evenly dispersed and dropped through the shunt umbrella cap. When the iron impurities go down with the material flow, it is quickly absorbed by the magnetic ring and separated from the oil seed. The cylindrical magnetic separator has the advantages of no power, energy saving, convenient use, and maintenance. crushing roller crusher is selected with reasonable structure, beautiful appearance, flexible adjustment, uniform and reliable feeding, good protection performance, large capacity, low power consumption, low noise, and simple maintenance; equipped with high nickel-chromium-molybdenum alloy toothed rollers, which has a longer life than ordinary rollers, even crushing, automatic hydraulic tight roller system, good sealing effect of the whole machine.


The main role of steam cooking is on the basis that flaking machine has destroyed part of cell structure, through water swelling and heating, breaking the oil cell, thereby further destroying the cell structure of the oilseeds; the protein in the oilseed is fully coagulated and denatured, and the colloid is destroyed, which makes highly dispersed fine oil release from the continuous colloidal phase and aggregated into larger oils. Steam cooking mainly uses a vertical steam cooker, which is formed by stacking several layers, the structure of each layer is basically the same. There is a side interlayer and a bottom interlayer. Feeding steam into interlayers to heat and cook the materials. There is a vertical axis at the center of the steaming cooker passing through each layer, and two paddle-type stirring wings on each layer are fixed on a vertical shaft to stir the material layer. The material height of each layer is controlled by controlling the blanking amount. At the same time, there is an exhaust steam pipe on each side wall, which is commonly connected with the main exhaust steam pipe to discharge evaporated water vapor in the cooking process.

Commonly known as a large oil tank oil press, its deceleration mechanism is helical gear transmission, which runs smoothly, increases transmission strength, reduces noise, and extends service life.

Crude oil from the tank area is sent to the crude oil tank in the workshop by pump after accurate measurement with mass flow meter enters the crude filter, remove bigger mechanical impurities in filtered crude oil, after exchanging heat between filtered crude oil with deodorization oil, heat with crude oil heater and mix with phosphoric acid whose concentration is 85% in oil acid mixer, the addition quantity of phosphoric acid is added at a certain quantity with metering pump according to processing capacity and crude oil quality. After mixing of oil and acid, enter acidification reaction tank to reduce the content of nonhydratable phospholipid, then enter oil alkali multiple effect mixer, after good mixing of oil and lye at certain concentration pumped by metering pump, enter neutralization tank, utilize liquid level automatic control in neutralization tank to adjust the reaction time, oil after reacting in reaction tank is pumped into plate heat exchanger to heat to about 90℃, and enters centrifuge to remove soap-stock; alkali refining adopts middle temperature reaction, high temperature separation, not only reduce saponification of neutral oil, but also improve separation effect of centrifuge and refining yield; the oil after removing soap-stock with first centrifuge enters oil water multiple effect mixer, which adopts frequency control, to prevent mixing strength is too big, oil and water emulsification,oil after water washing enters the second centrifuge for centrifugal dehydration, control dehydration temperature at about 90℃, dehydrated oil is heated to about 100℃ with plate heater, and then enters vacuum dryer for drying and dehydration, drying temperature is adjustable through automatic control, dehydrated oil enters bleaching premixing tank directly, soap-stock removed from soap-stock removal centrifuge is pumped into outdoor soap-stock temporary storage tank by soap-stock pump. Water separated by water washing centrifuge enters combined water separation tank, separated oil is pumped into crude oil tank in the workshop, separated water is discharged to outdoor water seal pool through the indoor trench to recycle residual oil in water.

Exchange heat between neutralized oil and deodorization oil, then heat to 105-115℃ with plate heat exchanger, enters premixing tank to mix with bleaching clay( 1-3% of oil weight), then overflow into bleaching tower(bleaching temperature and time are adjustable by automatic control), then use special oil slurry pump to pump it into two alternate horizontal filters to filter, filtered oil enters dewaxing section after, through polishing filters, waste bleaching clay is discharged to waste bleaching clay room.

Filtered bleaching oil enters the deaerator tank directly to remove oxygen in oil, deoxygenized oil quality exchange heat with deodorization oil, and heat with heat conduction oil heater to 250℃, then oil goes through filler part by the methods of falling film countercurrent stripping, stripping capacity is high, splash is little, fatty acid can be removed rapidly to avoid hydrolysis happen; oil flows into board part through the pipe, direct steam in board part erupt from oil with the shape of a bubble, and contact oil for stripping again, reduce the boiling point of odor matters through high vacuum board part, and through the distillation of superheated steam to reach deodorization purpose, and delay for thermal bleaching, deodorization oil is discharged from the bottom of deodorization tower, this process takes about 65~80min. Deodorization oil is drawn with a shield pump through an oil-oil heat exchanger, bleaching oil heat exchanger, crude oil heater, then finished oil cooler to cool to below 40℃, finally enters finished oil storage tank through polishing filter.

The whole plant adopts waste heat utilization technology. In every section, set energy-saving heat exchanger, finished oil at high-temperature exchanger heat with bleaching oil, dry oil, and crude oil in proper order from high to low according to different process temperatures, can make maximum use of waste heat of deodorization finished oil, reduce steam consumption. All steam condensate water from heating equipment is recycled into the hot water tank for reuse.
