We offer clients a wide range of oil mill machinery, machinery equipment like oil expeller, seed cleaner, filter press, etc. which find usage in the production of oil from different varieties of seeds like cotton seeds, sunflower seeds, mustard seeds, ground nut, linseeds, copra.
One of the main use of peanuts is to produce oil. At present, oil pressing is the most important consumption way of peanuts. Peanut oil processing is mainly composed of hot pressing method, since hot pressing process can get the full-bodied fragrance and maintain the nutritional composition and physiological active components in peanuts to the most. Through more advanced processing technology and peanut oil production equipment, the quality of peanut oil can be improved, and the capacity of peanut oil production can also be increased.
Peanut Oil Production Process
Pretreatment of Peanuts
Before oil production, there are certain requirements on the technical properties of oil, so raw materials (peanut) must be pretreated. Pretreatment for peanut oil extracting generally includes: cleaning, crushing, embryo rolling, steaming and stir-frying, etc. The equipment for peanuts pretreatment are cleaning sieve, flaker, cooker and more. All the equipment can be connected by seed conveyor to transfer all the materials automatically, saving labors and eliminating wastes.
Peanut Oil Pressing – Screw Oil Press
Pressing is the process of squeezing oil out of the material embryo by mechanical force. It is the way of physical pressing, and it comes from the traditional method of oil making in the workshop. Due to the rotation of the screw axis in the bore in squeeze boost, the pressed material continuously forward, at the same time, due to the squeezer spiral lead to shorten or root diameter increase gradually, make the pressing chamber volume shrinking and squeezing effect, in the process, on the one hand, push press material, on the other hand the pressed material compressed oil from a crack in the press gathering extrusion flow, at the same time, the residual oil cake is pressed out from the end of the screw shaft continuously.
Peanut Oil Refining
The purpose of oil refining is to remove harmful components from oil and minimize the loss of neutral oil and beneficial components according to different USES and requirements. The impurities in crude peanut oil can be divided into four categories according to its dispersion state: (1) suspended impurities (2) colloidal impurities (3) oil soluble impurities (4) water. The methods to remove the suspended impurities from crude oil usually adopts sedimentation, filtration and centrifugal separation. The basic peanut oil refining process are degumming, deacidification, decolorizing, deodorizing and dewaxing.
Start peanut/groundnut oil production business is relatively easy compared other unconventional raw materials, since it is relative easy to get the raw materials and easy to sell it to the market. The most important factor for this business is how to choose the ideal peanut oil production equipment. Our company has many successful cases and projects about peanut oil processing.
