Groundnut oil extraction technology is used to extract oil from groundnut kernel. The equipment for groundnut oil production contain cleaning machine, husking machine, flaking machine, cooking machine, pressing machine, solvent extraction machine and refinery machine. And there are two kinds of groundnut oil extraction technology usually used in cooking oil production industry. One is physical pressing technology and the other is solvent extraction technology.
Physical pressing technology is suitable for small scale or medium scale groundnut oil production, usually 1-30 tons per day. Solvent extraction technology is the best choice for large scale groundnut oil production, more than 30 tons per day. Whichever technology you use, the groundnut should be pretreated ahead.
1-10 tons per day small scale groundnut oil production line
Cooking machine, oil press machine and crude oil filter machine
Because of the small capacity, Henan Doing Company recommends these three machines to customers for groundnut oil production, and using physical pressing technology of groundnut oil extraction. But before cooking, the shell of groundnut should be removed by hand to prevent residual oil from increasing. Cooking machine is to adjust the temperature of groundnut kernel, in order to increase the oil yield. The groundnut oil pressing machine is to extract oil from groundnut kernel by physical extrusion. And the filter machine is to remove the impurities in crude groundnut oil.
10-30 tons per day medium scale groundnut oil production line
The equipment used in medium scale groundnut oil production line
About 10-30 tons per day capacity, the engineers of Henan Doing Company can design the groundnut oil production line according to customers' need. But most customers choose to use physical pressing technology of groundnut oil extraction. The difference from small scale is that the equipment used in pretreatment section are more, and the processing effect is better.
More than 30 tons per day large scale groundnut oil production line
Large scale groundnut oil production line
More than 30 tons per day, and in order to reduce the residual oil rate, Henan Doing Company suggests using groundnut pretreatment, pre-pressing and solvent extraction technology. This kind of technology can make the residual oil rate less than 1%, and the groundnut meal more suitable for as animal feed.
Besides the groundnut oil processing machine, Henan Doing Company also provides 1-600tpd groundnut oil refinery machine. They are adopted mature refining technology and high quality steel. If you need, please leave your message.
