Cleaning process
Peanut adopt vibrating screen,removal impurities,then adopt sheller to separate the kernel and shell.
Cooling and fine filtration process
pump the coarse filtered oil into cooling oil tank to further cool it to a lower temperature, and colloid
impurities in crude oil temperatures condense gradually in the critical condensed temperature. Pump the frozen oil into the oil filter, and the colloid impurities are stopped by filter medium and then separated from oil.
Extraction
a) Adopt stainless steel fixed grid plate and increase the horizontal grid plates, which can prevent the strong miscella from flowing back to the blanking case, so as to ensure good extraction effect;
b) The rotocel extractor is driven by rack, with unique rotor of balanced design, low rotating speed, low power, smooth operation, no noise and quite low maintenance cost;
c) The feeding system can adjust the rotating speed of airlock and main engine according to the feeding quantity and maintain a certain material level, which is beneficial to the micro negative pressure inside the extractor and reduce the solvent leakage.
Advantages
(1) High peanut oil yield, obvious economic benefit.
(2) Less residual oil rate in the dry meal.
(3) Improving the quality of the meal.
(4) Low processing cost, high labor productivity.
