Groundnut (peanut) oil is one of the most commercially rewarding oils to extract because of its incredibly high yield. A high-quality batch of groundnuts can yield up to 45% oil. However, to extract that final 5-10% of oil hidden deep within the seed, your machinery must be engineered for relentless, continuous pressure.
The Mechanics of Groundnut Pressing
Unlike mustard, groundnut produces a very thick, protein-dense oil cake. If your machine's gearbox is weak, or if the worm shaft allows "slippage," the thick cake will clog the chamber, causing the machine to jam and waste potential oil.
TechVMouta's Engineering Solution
TechVMouta commercial expellers utilize multi-stage pressing chambers forged from EN31 Alloy Steel. This specific geometry grabs the groundnut seed and forces it forward under extreme pressure without slippage, ensuring maximum oil recovery (leaving minimal residual oil in the cake).
Filtration is Non-Negotiable
Because groundnut cake is so dense and dusty, the crude oil flowing out of the expeller will carry fine peanut particles, appearing cloudy. You cannot sell this directly. Every groundnut oil mill must integrate a heavy-duty TechVMouta Filter Press to force the crude oil through micro-cloths, resulting in the clear, golden peanut oil consumers expect.
Motor Efficiency in High-Volume Mills
Because groundnut mills often run high volumes to supply the cooking oil sector, energy costs accumulate rapidly. TechVMouta strongly advises groundnut processors to utilize our PM Series Motors. By maintaining exact RPMs under the heavy load of groundnut crushing while consuming up to 50% less power, PM technology directly increases your net profit per liter.
