How To Improve Peanut Oil Yield

Usually, the oil production rate is a general data, it varies from the groundnuts you are processing, let's take peanuts for example, peanut oil yield is around 35% to 45%, however, this data is can be maximized with proper extraction methods.

How to Improve Peanut Oil Yield

Choose Dry Peanuts and Well Prepared

You should choose dried and plump peanuts instead of wet. Groundnut should be sundried and removed the impurities such as stones, snad, dust etc. If the capacity is small, you can choose to do it manually, but if the capacity is large, then you should think about the proper groundnuts cleaning equipment.

Well Control the Cooking Temperature

By cooking peanut kernels, 80% of the seeds are cooked properly, lift the peanuts by hand to see if they are in a condition that the kernel, husk has separated. At this time, the kernel lignet appears yellow. The oil is more active at higher temperatures, the seed exits the cooking machine when it reaches 130ยบ C, if at this temperature the oil is expelled then more oil can be obtained.

Choose the Right Oil Press Machine

The quality of the oil press machine has a large effect on the yield of oil. Mainly on the machine itself, this is the temperature pressure of the press cage and screw shaft. Finally, the high residual oil content on the cake. As we know, if the cake is too thick and high in oil, we get less oil. Therefore for high oil recovery, we should try to get thin cakes in oil press work. The oil press machine is capable of controlling the thick and less than 7% residual oil content of dried cakes.

How Coconut Oil Has Been Extracted

There are several methods of extracting oil from coconut, known as copra. In general, there are three main types of coconut extraction: centrifuge extraction, expeller processing and cold-pressing. Centrifugally Extracted Coconut - A machine spins chopped coconuts around, using centrifugal force to separate the oil from kernel. The final product does not require processing or further refining. It can be eaten straight off the spoon. Aside from its light, pleasurable taste, it is also considered raw as it retains all the nutrients of the coconut. These make centrifugally-extracted pricier than others. Expeller processing - This process uses an oil extraction machine to separate the oil from the kernel. It heats the coconut, typically at 210 degrees or more but never beyond 400 degrees (which is the temperature used in refining). Then, the heated kernel is crushed using mechanics and expeller-pressing , squeezing the oil out of the roughage. It does not rely on chemicals for the e...
