Rice bran extrusion pretreatment process is the most reliable method to form, fresh rice bran, to prevent rancidity and improve oil yield. Rice bran evenly flows from disc feeder to bran and tips separation wind network, to separate some isolated rice and bran shell which against extrusion, and then into container. Rice bran through high temperature, high pressure, shear, friction, exploded instantaneous in?extrusion machine, will has a series of physical and chemical reaction, forming many microporous and a certain intensity of expansion?material.
The main purpose of flaking is to destroy the cell wall of material, granular were press into sheet, increase the surface area, thickness change,changing the external structure of the material, which is favorable for heating, but also conducive to the absorption of water wetting and ?volatile water when cooking, create favorable conditions for the follow-up process. In order to prevent embryo powder increased, the thickness should be controlled in 0.25 – 0.35 mm is more appropriate.
easily lead to high temperature oxidative polymerization, decomposition of peroxide and some harmful substances, destruction of species of nutrients. high temperature caused by protein denaturation, greatly reducing the content of polyunsaturated fatty acids in flaxseed oil, and even produce trans fatty acids.
The groundnut oil is obtained by storing, cleaning, crushing, flaking, steam cooking, oil pressing, oil filtering processing, or by solvent extraction of the raw materials. By using our groundnut oil processing line, you could get high quality and high nutritional oil and cake. The cake, as we all know, can be good feed for some livestock. We could also provide small scale, medium scale and large scale groundnut oil processing mill plant according to customers’ different requirements.
The process begins with cleaning. Magnets are used in order to remove any trace metal, and the seeds are scrubbed of any foreign matter. If the moisture content of the seeds is too high it will have an adverse effect on the sunflower oil produced, so we dehull. The seeds are cracked by a pneumatic or centrifugal sheller, and the result is winnowed to separate kernel from hull.
The Sesame Oil Making Plant of this section includes screening machine unit, stoning machine, magnetic separator, winnowing machine and so on. All these equipment finish the process of raw materials feeding, screening, stone removing, magnetic separation, and the complete process of cleaning dust, air generated from this section. This section could reduce damage to the subsequent machines.
