Professional Soybean Oil Press Machine for sale

Soybean Oil Press Introduction

Soybean oil is a vegetable oil that is extracted from the seeds of the soybeans. Soybean oil is one of the most widely consumed cooking oils across the world. In order to process soybean oils from soybeans, soybean oil pressing machinery is necessary. Soybean oil press machine designed by our factory is the advanced oil processing machinery, characterized by the high oil output rate with good quality, simple design, easy to use and continuous operation. They also can be used for various raw materials, such as peanut, beans, rape and cottonseeds, sesame, olive, sunflower, coconut, grass seed etc.

How to Get Soybean Oil Press?

Soybean Oil Pressing Main Process:
Soybean seeds→cleaning→crushing→extusion→flaking→drying
Soybean Oil Press Working Process:
For the soybeans there is hot or cold pressing. In both cases the seeds are first picked (husks separated from the seeds) in hot pressing, after selecting the seeds, water is then added to soften the material, then the seeds are steamed after which they are ready for pressing. In cold pressing, after picking, the seeds are directly taken for pressing. The screw is rotated by an electric motor to crush the beans. After this step if only it was crude oil required, it is enough, but if it is pure refined oil that was required, you will need additional oil refining machinery to produce cooking oil and meal (used as animal feed or sometimes as a fertilizer due to the high nitrate content).

1.cleaning: in order to obtain high effective cleaning, ensure good work condition and production stability, high efficient vibration screen was used in the process to separate big and small impurity. suction type gravity stoner removing machine was applied to remove the shoulder stone and earth, and magnetic separation equipment without power and exhaust system were used to remove iron. Dust removing wind net is installed.

2.Crush:in order to ensure good softening and flaking effect, soy is generally broken up uniformly to 5~6 flakes and water distribute uniformly during softening, and flakes is thin and burliness.

3.Extrusion process: adopting the bulking machine can both improve the yield of soybean oil and reduce consumption. The extrusion puffing, on the one hand, can make solution lipase in the soybean passivated under high temperature and high pressure condition, then prevent the rice soybean oil rancidity; On the other hand, the extrusion puffing can make soybean be porous material grain, and increases the materials bulk density, then improve the permeability and leaching rate which solvent reacts to the material.

4.Flaking: flaking means a certainty granularity of soy lamella was prepared for flaked of about 0.3 mm, the oil of raw material can be extracted in the shortest time and maximum, and residual oil was less than 1%.

5.Drying process: the puffed soybean contains about 12% water, and the best moisture for leaching process is 7-9%, therefore, there must be effective drying means to achieve the best leaching moisture. Adopting counter-current dryer can make water and temperature meet with follow-up process requirements, and improve the oil yield, as well as oil quality.

Soybean oil press Advantages

1.Easier to operate, install and commissioning.
2.Wide application for various seeds and nuts.
3.Small investment, fewer land space, fewer labor but with the complete function of the production.
4.It can avoid the unstable material feeding caused by manual and can make the worker safety more under the higher temperature working situation.
5. High oil yield and good condition oil cake.
6. Sanitary and durable. The automatic machine is made of carbon steel.

What is soybean oil?

Soybean oil is a vegetable oil extracted from soybean seeds. The quantity of Soybean oil ranks first all over the world. There are many kinds of soybean oil. Automatic processing methods, there are pressing soybean oil and solvent extraction soybean oil. According to the type of soybean, it contains crude soybean oil and genetically modified organism soybean oil. The colors of crude soybean oil vary with the breed of soybean. In generally, the color is yellowish, light green, puce, etc. Refined soybean oil is yellowish. The soybean oil with deep color have beany flavor, and also its thermo stability is poor. When heating, the soybean oil will produce more bubbles. Soybean oil contains more linolenic acid, easily to oxidate and produce “bean smell”. Soybean oil contains 7-10% palmitic acid, 22-30% oleic acid, 2-5% stearic acid, 50-60% linoleic acid, 1-3% arachic acid, 5-9% linolenic acid.
Soybean oil is a kind of frequently-using cooking oil which is commonly sais soybean salad oil. Soybean oil is extracted from the seeds of the soybean seeds through cold pressing or hot pressing. About cold pressing oil, it has light color and light soybean flavor. As for hot pressing oil, the high-temperature processing has lead to high oil yield. Whereas the color is deeper with the thick bean smell. According to the process, it contains crude soybean oil, filtered soybean oil, refined soybean oil. Crude soybean oil is tawny, whereas most of refined soybean oil is yellowish with large stickiness. If soybean oil is exposed to air for a long time, the surface of soybean oil will appear unstable film. Soybean oil nutrition value is higher than other oil, many people in China like it.
