Peanut Oil Pressing Method

Peanut Oil Pressing Method

the process of producing Peanut Oil is as follows

Peanut kernel → Cleaning → crushing → flaking → cooking → pressing

Operating instructions:Peanut oil is higher oil content,oil content as high as 40-50%.Cleaning with specifications of 10 mesh / inch screen,so that impurities do not exceed 0.1%,then broken by the crusher,and broken up to 4-6 flap,by rolling embryo,and then into the steaming and frying section to make its moisture content of 1-2%,temperature up to 120-130 degrees before pressing.

Note:If no crushing and rolling embryo equipment, can also cooking screening peanut use the flat-bottomed cooker (drum cooker can add water 4-6%, flat-bottomed cooker can add water 8-10%), cooking peanuts to light yellow, the temperature reached 110-150 degrees, they can start pressing.

Solvent extraction is a process to extract the oil from oil bearing materials by means of a solvent. A typical solvent used is hexane, a by-product of petroleum. The solvent extraction plant is designed to extract oil directly from oil seeds containing less than 20% oil, like soybeans, after flaking. Or it extracts oils from pre-pressed or fully pressed cake of seeds containing more than 20% oil like sunflowers, peanuts, cotton seed, palm kernels, canola, copra, castor and a variety of other materials.
The purpose of solvent plant extraction is to remove most of the oil contained in the seed. Extraction is conducted on prepared seeds or, as generally occurs in the case of high oil content seeds, the cake obtained from pre-pressing. Solvent extraction consists of a sequence of five operations:
Preparation of seeds for extraction which includes pre-pressing for high oil content seeds.
Extraction of oil from the prepared material with the aid of a food-grade solvent.
Desolventising-toasting of the de-oiled seed/meal, often combined with drying and cooling of the said meal.
Distillation, to remove the solvent from the extracted oil.
Recovery of solvent, which is reused again and again at the extractor level.


Simple in structure with stable performance;
Additional horizontal grid plate prevents the miscella from flowing back into the material cell to ensure the best extraction effect;
The wet meal is discharged by the material discharger which continuously discharges the wet meal onto the wet meal conveyor. This avoids meal bridging, un-uniform wet meal discharging and extends the serviceable life of the wet meal conveyor.
Composed of pre-extraction, extraction and draining sections. There is material turnover in the process of extraction to make the extraction uniform and thorough. Special self-cell solvent spraying ensures the best effect during extraction.
Features of the Solvent Extraction Process

Evaporation takes place in a vacuum for the best oil quality.
Extraction system can process different raw materials.
Solvent recovery system from vent gas is particularly absorbent.
With full energy conservation and repeat utilization, steam consumption is markedly reduced.
Solvent Extraction Plants Supplied by Yongsheng

In order to meet different clients` requirements, we have a wide range of equipment with capacities from 300 kg to 100 metric tons. When refined, oil grades may qualify as Grade 1, Grade 2, Grade 3 or Grade 4. There are two technologies: one is batch, the other is continuous. Normally we adopt batch-type processing for capacities less than 20 t/d. Otherwise the process adopted is semi-continuous or continuous.

We continue to research new equipment. Yongsheng develops equipment designed to be fully automatic, utilizing advanced technology that can be combined according to different clients` requirements. The latest refining equipment consists of many single units and has a self-contained heating system which saves energy since it does not use a boiler. This equipment requires a smaller workspace and costs less. Furthermore, it has a wider range of functions and can be used to produce Grade 1, Grade 2, Grade 3 and Grade 4 oil.
