Sunflower Seed Oil Extraction Methods
Sunflower seed oil is extracted from oil-type sunflower seed by the mechanical pre-pressing method with subsequent hexane extraction of the remaining oil in the meal. To be specific, oil-used sunflower seeds contain 45%~60% of the oil which is suitable for the pre-pressing and leaching method: In the 1st, the raw seeds are pre-squeezed by means of a continuous screw press. The 2nd extraction type is solvent extraction, and the commonly used solvent is mainly hexane-based solvent VI or other solvents such as propane, butane, isohexane, etc.
The extracted sunflower seed oil is of a golden yellow color with a touch of nutty fragrance. Because it is rich in linoleic acid and has rich nutrients for maintaining human health such as vitamins A, B, D and E, sunflower seed oil is known as “health care products”,”senior nutrition oil” or “health oil” and so on.
Sunflower Seed Oil Press Introduction
The professional sunflower seed oil press is ZY24(202-3) continuous oil extraction machine. In small and medium-sized vegetable oil plant, ZY24(202-3) continuous pre-pressing machine is a popular equipment for pre-squeezing and leaching process. ZY24(202-3) pre-pressing machine, which is redesigned on the basis of the 202 pre-pressing machine, has advantages of the reasonable transmission gear, compact structure, and small footprint. And the machine has achieved improvements in the aspects of steaming, dehydrating, uniform feeding, mechanical wringing, and squeezing cage loading and unloading.
Features of ZY24(202-3) Pressing Machine
ZY24(202-3) pressing machine’s characteristics have suited to pre-press sunflower seed oil. Under normal pre-pressing conditions, its features are:
The machine is made up of stainless steel. The use of high-quality steel carburizing heat treatment can greatly extend the service life of the equipment.
Large capacity, small workshop area, low power consumption, less operation management and maintenance work.
The structure of the pre-squeezed cake is loosened but not crushed, which is favorable for the solvent to permeate when leaching; And the oil content and water content of the squeezed cake are suitable for solvent extraction.
The quality of squeezed oil is better than that of squeezing or leaching once.
Sunflower Seed Oil Press Application
The pre-pressing machine has a wide range of applications that it can be used to squeeze a variety of oilseed source crop, such as rapeseed, peanuts, cottonseed kernels, sunflower seeds and so on.
The machine can be used alone as oil pre-pressing equipment or it can be used for twice pressing in the oilseed pretreatment production line with other equipment according to customer needs, and we will choose the right model to the customer.
With special design, online installation instructions and after sales service, our sunflower seed pre-pressing machine has exported to Southeast Asia, Africa and other countries and regions.
