Peanut Sieving Line Grade: Commercial Use

Peanut Sieving Line

Peanut Shelling begins with raw peanut pods, the foreign material(such as leaves/stones) can be removed by de stoner. 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 processing

Peanut sieving is a primary processing of peanut kernels, when peanut kernels are collected from farmer, the first section is to grade and select them into different grades according to the size, generally we divide the peanut kernel into 24-28, 28-32, 34-38, 35-40, 40-50, 50-60, 60-70(per ounce).

Sorting conveyors are designed for picking out imperfect and moldy peanut kernels by workers, this step can also be finished by color sorter.

Packing section is the final step of the whole line, due to several sorting conveyors are installed, we have to match corresponding packing machines at end. The packing machines combine the function of measuring, filling and sealing together.
