The basic process of pressing process oil


1 conventional production process: raw materials - steamed fried - press - machine pressed crude oil
(2) Special grease production process: Oil processing - Broiling - press - filter - fragrance oils
Three special oil production process: Oilseeds - whole seed cold pressing - filter - cold-pressed oils
Fuel oil is squeezed out of the process: When the fuel into the oil press virgin bore, with the pressing chamber rotates, the pressure increases. As the seed material extruded continuously squeezing oil, virgin material particles in direct contact with each other and cause a pressure deformation of seed material, particularly in the oil film rupture and the adhesive body. Such bombing bore after being squeezed, squeezed material is not a nmb seed oil press to form a plastic body, called the cake. Squeeze due to the dual role of temperature and pressure, will continue to deteriorate protein, thereby affecting virgin plastic material, in short, in order to ensure an appropriate level of protein denaturation best squeeze out the oil effect.

Edible points "squeeze " "leach " in two oil processing

Pressed oil is separated by mechanical pressure to allow oil from oil , and extrusion. This method is natural pollution is authentic head and said virgin oils , maintaining the oil extraction is rich in vitamin E ( antioxidant , aging ) , lecithin , unsaturated fatty acids and various nutrients , authentic, oil high product concentration , wall over time , usage of only 1 /2 of the ordinary oil , to " eat oil , eat oil" health purposes fundamentally reflects green, natural , nutrition, health. " China Business" June 24, 2002 edition 14 newspaper reports : to ensure a high nutrient content of edible oil processing process will be popular !
Leaching rule is the 6th light gasoline and chemical solvents such as benzene , canning soaked , volatile extraction , this method destroys the nutrients oilseeds , taste is not good , refined oil contains toxic to humans is difficult to remove residual solvent and clean , a chemical system oil process, this production process handling capacity, low cost, profitable , mostly domestic vegetable oil plants are using this technology .

How to improve the oil yield oil processing

Before using the press, first of all should be ready aids and containers , check and adjust the belt tightness . Then start the motor , the machine empty running around 15min, check the speed of the pressing screw shaft. Average speed should be around 33dmin. Do you want to pay attention to when idling gear box gear meshing and sound normal, whether nmb oil equipment and motor parts properly. When press idling , the motor current should be about 3A. If the current is too high , you should immediately stop checks, adjustments and then boot.
After the load is normal, around 50kg ready rapeseed or soy , ready to put into the hopper . Note: When you start squeezing feed not too fast, otherwise the sudden increase in pressure within the bore virgin , virgin not turn the screw shaft , causing blockage virgin bore , even to squeeze cage rupture, a major accident . So at the beginning of the compression , the seed oil press be evenly slowly into the hopper , so press be run together . So repeatedly , sustained more than 3 ~ 4h , so press the temperature gradually increased , and even take smoke ( this is normal ) . At the start of the press virgin bore low temperature, can be slowly twist the handle on the withered section stud , increase the thickness of the cake , while improving water into juice billet , to be squeezed bore temperature. Rose to about 90 ℃, the normal operation of the press , the cake thickness can be adjusted to 1.5 ~ 2.5mm, and tighten the nut tightened.

oil processing principle structure

 When press operation , after a good deal of oil squeezed from the hopper into the breech . Pressed by the screw to keep the embryo transfer so that the material in advance , be pressed . As the material of the embryo in the press virgin bore in the state of motion oil extraction out under conditions of high pressure pressing chamber , producing a great deal of friction between the embryo and the virgin material snails, embryos and virgin material breech , so friction can cause relative movement between the micro- parison material . On the other hand , due to the pressing screw root diameter is gradually thickening Park pitch is gradually reduced , so when pressing screw rotation , screw hard material embryos that can move forward , but also outward and upward while pressing screw thread close as the surface of the material layer is also pressed axis. Such virgin bore in each embryo particulate material , such as the speed is not the same direction, but also exist between the relative motion of particles . The heat generated by friction and the oilfield equipment process operation to meet the necessary heat helps to promote the parison thermal denaturation of proteins , destruction of the gel, to increase the ductility , while also reducing some of the oil to the viscosity tends to be precipitated , thus improved oil yield oil press , so there is oil squeezed out feed and discharge gap and the gap outflow of exhaust from the park.

oil processing thereby reducing

Peanuts and sweet, flat , spleen and stomach , lungs and phlegm , qi hemostasis for spleen nmb oil processing  eat less fatigue , dry cough with little phlegm , postpartum milk shortage embolism. Peanut fat liver can break down cholesterol to bile acids , and promote excretion, thereby reducing blood cholesterol levels , for the prevention of atherosclerosis .
Winter is the high season pruritus . Chinese medicine believes that winter is mostly due to itchy skin caused by dry weather . Patients with the disease can be nourishing and moistening treatment oil equipment . Such as pig 's blood boil peanuts Meidou efficacy pretty good .
