Main Groundnut Oil Processing Steps

  • Seeds Cleaning Process

Remove impurity (silt, pebble, iron chip, etc.) to reduce wear and tear on internal parts of oil press and improve oil yield. The main equipments includes cleaning screen, stoning machine, magnetic separation machine.

  • Peanut Shelling Process

Put the harvested peanut into professional groundnut shelling machine to remove the shells and get the seeds (kernel content: 65%-75%). With the development of vegetable oil production industry, shelling process been basically mechanized. The production efficiency is also greatly improved! Its supporting equipment is: sheller, separation screen, separator, and so on.

  • Seeds Broken

It is ok to press the oilseeds as a whole. But Crushing and rolling the seeds is mostly adopted in medium and large scale groundnut oil mill plant, as the oil yield can be increased obviously.

  • Seeds Roasting Process

The groundnut kernels are then put into the roasting machine with automatic temperature control system. It is the key step to determine the yield of peanut oil. Experienced operators can control the cooking temperature and time very well to get high oil yield. Its supporting equipment is: crusher, rolling machine or flaking machine.

  • Oil Expelling / Pressing Process

A good unit of groundnut oil press machine can not only save a lot of trouble in oil processing business, but also can reduce production cost and increase profit. Actually, screw type peanut oil making machine can process various different oilseeds, such as rapeseed, soybean, cottonseed, tea seed and other vegetable seeds.

  • Oil Filtration Process

The oil expelled from oil presses might looks a little muddy, and doped with some foam. So filter press is needed to ensure the purity of groundnut oil with gold color and good flavor.

  • Oil Refining Process (Optional)

Is small- scale groundnut oil processing a profitable business? How about the costs and returns? When running groundnut oil plant, the key is to minimize the capital and operating coast, and maximize the incomes from the sales of oil and other co-products. So it is necessary to do a careful study of all costs before setting up your own oil processing plant. In particular to assess the cost of purchasing the main peces of equipment, expected labor wages and oilseeds purchase cost, the cost of fuel and power. The price of produced oil and co-product depends on many factors including, quality, the number of competitors, and their type and oil quality. Predict the likely profite at your planned scale production over the year, each indicator should be evaluated and then compare the production cost with the expected revenue to calculate the possible profitability of the oil production business. Besides, it is necessary to make full use of the oilcakes (by-products) to make the enterprise financially successful.
