Pretreatment of oilseeds

Pretreatment of oilseeds, oil equipment when handling fuel, you need to be pretreated, after pretreatment, to be able to be processed into products we need, then pretreated oil has, what does? Here together to understand the pretreatment processoilseeds. 
Oil in the press, leaching or stewed before first processed to make it physical or physico-chemical properties most suitable forthe separation of oil and non-fat ingredients, this process is called oil pretreatment. Pretreatment plant oils, including cleaning,shelling, rolling stock and steaming and roasting operations .

                   
① to clear up is the use of a variety of devices contained in the oil separation process impurities. The purpose is to reduce theclean up oil loss points, the processing amount of the oil to increase the rate, quality of fats and by-products and equipment, to avoid accidents, improve the operating environment. Many types of impurities, but significant differences exist in the oil andimpurities, particle size, relative density, shape, surface condition, hardness, magnetic and kinetic properties and other physicalproperties of gas oil, and grease production plant often used in screening, magnetic separation, wind election, the relative density of stoner methods and equipment, the oil and impurities separation. 
② sheller : sheller purpose is to increase oil yield, to improve the quality of crude oil and meal to increase the effectiveproduction equipment, which will help billets and other follow-up processes. Sheller There are many ways, are commonly usedby the rough surface grinding rubbing action makes oil hull broken; through impact with the wall or playing board action to makethe hull broken; borrow sharp shearing so broken hull oil; borrow squeezing action so that the roll crusher hull oil and the like.
