Oil Seeds Pretreatment and Pressing Technology
Description of the process for Vegetable Cotton Seeds, Rice Bran, Sunflower Seeds Oil Press Equipment
Raw material use vibration sieve to filter through 1#bucket conveyer, to get rid of impurity ,clod and smallstones in raw material. Through 2#bucket conveyer, the kernal reaches magneticer selector to remove iron.In the flaking process ,kernal is divided into 4-8 parts and making flake.Material arrives at the cooker vessel through 3#bucket conveyer,which is softy and roasting for extend its oil molecule,so it is easily pressed and improve the rate of output oil ,then at the help of 4#bucket conveyer and flat conveyer, reaches oil press to be pressed ,and get the oil and cake ,the oil is filted and go to rude oil tank,the cake is take out of the workshop .
Clearing equipment for Vegetable Cotton Seeds, Rice Bran, Sunflower Seeds Oil Press Equipment
1.Screening machine is for ridding off big and small impurity.
2.Magneticor is isto rid off the iron, Stable quanlity,easy operation,rational structure,beautiful feature,low noise,high productivity.
3.Dust catcher is to rid off the dust,reduce the pollution of air, Little waste gas:compare with other methods,exhaust hardly contains dust,decrease air pollution and loss of oil.
4.Crusher equipment
To make the sunflower seed into pieces between the thickness 0.3 - 0.35 mm , so it's well proportioned by heating.
5.Steaming and drying process.
The process is to Add the hot water into the seeds crushed/flaked to moist ,to add steams for steaming the seeds, to dry the seeds for ridding off more water content .
In the process, with the water and temperature to make the protein of seeds change the character , make the oil moleculeo loose for easyly pressing to get rude oil ,also get the better cake and oil .
Water content :5 - 10 %; temperature : 105 - 110 degrees ; Requiring Time : 60mins .
Pressing process for Vegetable Cotton Seeds, Rice Bran, Sunflower Seeds Oil Press Equipment
The process is to press the seeds and get enough oil . Requiring water content :3.5- 4.2 % ;Temperature 105 - 110 degrees ; Residue oil of cake : 6% or so .
Filtering Oil for Vegetable Cotton Seeds, Rice Bran, Sunflower Seeds Oil Press Equipment
Firstly to fiter the rude oil with oil-dreg sieves,who run reposefully, less malfunction, less occupying area , it's the better oil-dreg seperator,then use oil filter.

Remove solubility impurity in the crude oil is degumming. Because phospholipid in a great part of solubility impurity in the crude oil.In industry, degumming also calls get rid of phospholipid. Before alkali refining, remove solubility impurity is a very useful way, it can reduce loss in the oil, increase oil quanlity, save alkali, and phospholipid can be got.
Crude oil is pumped out from the Buffer Tank. Passing through dosing system, the oil enters into the Heat Exchanger to recover part of heat. Heat the oil to design temperature(70°C)by Heater. The oil is mixed with dosed phosphoric/citric acid in Mixer. Mixture of oil and acid enters into the Mixer to change the un-hydrated phospholipids in oil into hydrated phospholipids. Add in alkali to neutralize the oil. Quantity of alkali added is determined by the quality of crude oil. The neutralized oil is heated to separation temperature(90°C)and then enters into the Centrifuge to remove the phospholipids, FFA and other impurities etc. Roughly 5-10% hot water is added into the oil to remove the residual soap in oil coming from Centrifuge. Generally temperature of hot water is 3-5 °C higher thanthat of oil. In order to get a more consistent washing effect, phosphoric/citric acid is added in. Mix oil and water in Mixer and heat it to 90-95 °C, then the mixture enters into the Centrifuge to separate the residual soap and most of the water. Water enters into the Separator to separate oil in water and separate the oil further by outside pool.
Decolorer for Vegetable Cotton Seeds, Rice Bran, Sunflower Seeds Oil Refinery Plant
The aim of decolor is improve the color of oil, and supply the eligible oil to deodorizer. So the standard of oil should be made according to the demand of oil.Through decolorer, we should get the most change in the color, at the same time, keeping the lowest loss.
The oil firstly enters into Heat Exchanger to make heat exchange with the deodorized oil (a Heater will be extraly used at the beginning of starting up the plant). When the oil has been heated to design temperature (110°C), the oil is continuously mixed with clay proportioned by an automatic feeding system before entering Vacuum Bleacher. Then in time, during continuous agitation (by steam),the main part of color bodies as well as oxidizing materials in the oil are absorbed by the clay.After the bleacher, the oil/clay mixture is pumped to alternatively working filters and safety filter to remove clay in oil. The bleached oil tank is under vacuum to avoid contacting with air and thus cause color return and affect peroxide value of oil.
Deodorizing Section for Vegetable Cotton Seeds, Rice Bran, Sunflower Seeds Oil Refinery Plant
Deodorizer not only remove the fetid impurity, increase oil smoke point, make better taste, but also improve oil stability, quanlity and chroma.At the same time,we can get rid of free fatty acid, peroxide, heat-sensitive coloring matter, protein in the mucid oil cake, polycyclic aromatic hydrocarbon, and residual pesticide residue. In the oil process, we always emphasized deodorizer.
The standard bleached oil enters into Heater, Heat Exchanger, and Heater, and the oil is heated to process temperature (240-260°C). Subsequently pump the oil to Deodorizer. The deodorizer is combined type: the upper is packed type to remove odor producing components such as free fatty acid; the bottom is plate type to get hot bleaching effect. Oil from the Deodorizer enters into the condenser to recover most of the heat and makes further heat exchange. Finally the oil is cooled to 80-85 °C by Cooler. Volatile from the deodorizing system is separated by FFA Scrubber. The separated liquid is FFA at 40-50 °C.
Edible Oil Refinery Equipment step 4: Fractionation of oils and fats Process
Dry fractionation of oils and fats is the separation of high-melting triglycerides from low-melting triglycerides by crystallization from the melt. Apart from blending, it is the cheapest process in oils and fats processing. It is a pure physical process compared to other chemical modification processes such as hydrogenation and interesterification which modify triglycerides. Dry fractionation is now applied to many kinds of fats: palm oil, anhydrous milk fat, tallow, fish oil, lard, cottonseed oil, sunflower seed oil, palm kernel oil, tallow butter fats, and special fats.
The most important applications are: palm olein used extensively as frying oil, palm super olein as salad oil and frying oil, the palm-mid fraction as component of cocoa butter equivalent, palm kernel stearin as cocoa butter substitute, anhydrous milk fat fractions for bakery and confectionery products, spreadable butter, tallow olein for frying oil and spreads. In this process, the fat is melted and heated to eliminate any crystal memory. The molten fat is cooled down under controlled agitation and cooling conditions to produce crystals nuclei formed by the higher melting triglycerides. Then, nuclei will grow to form crystals of the desired size. When the crystallisation has progressed far enough, the slurry is separated.
