High Praised High Efficient Groundnut Shelling Sieving Processing Plant

Groundnut Shelling Sieving Processing Plant begins with in-shell peanuts, pass shelling/sieving/sorting/packing, finishes at Calibrated peanut kernels with sack packing. This line realizes automatic industrial production of peanut pretreatment, saves labors, has obvious advantage comparing with traditional processing. Finished product can reach to export level.

It covers bellowing steps:

Peanut Shelling: It begins with in-shell peanuts, the foreign material (such as dirt, peanut vines, sticks, stones, peanut hulls etc.) can be removed by gravity peanut destoner. Next, peanuts with shell will be feed into twin-rollers' chamber for shelling, the gap between rollers should be adjusted as per the peanut size, too narrow will crack the peanuts, but too wide will cause unshelled peanuts increasing. At the same time, there is a rotating beater crushes the peanuts against the bottom, in order to push the shells and kernels out of shelling chamber. Shells and kernels will be separated on the function of both vibrating screens and air blower. Finally shelled peanuts are obtained and fall to next sieving section.

Peanut Sieving:  It is a principal processing, when peanut kernels are shelled, the first section is to grade and sort into different grades according to size difference, generally we divide the peanut kernel into 24-28,28-32,34-38,35-40,40-50,50-60,60-70(per ounce).

Peanut Sorting: This section can be designed into two types, one is manual sorting, another adopts optoelectronics technology-sorting by color sorter. Broken, split, unshelled, minor defects, damaged kernels, foreign material will be sorted out.

Peanut Packing: due to different market demand, packing machine can be designed with different packing range/types. The packing machines combine the function of measuring, filling and sealing together.
