Groundnut peanut grading machine for multiple grades

4.6/5 - (12 votes)

Groundnut grading machine is mainly used to screen peanut kernels, almonds, hazelnuts, cashews, palm, pine nuts, macadamia nuts, and beans of different sizes into three levels or more. The sorted products are more suitable for further processing and sales. The peanut sorting machine serves as the supporting equipment of the nut shelling or peeling machine. The peanut grading machine has a reasonable design, high efficiency, and low crushing rate, so it is a piece of popular equipment for sorting granular foods in the food processing industry at present.

Groundnut grading machine features

  • Multiple grading functions. The peanut kernel grading machine can be equipped with one, two, three or more layers of screens. The products can be sorted into one to three or more classifications based on their sizes.
  • High effiency and output. The capacity of the groundnut grading machine can reach 600-800kg/h. If customers have special needs, we can provide customized service. All the vibrating sieves work at the same time and automatically discharge the products.
  • Low breakage rate
  • Durable and long service life
  • Reasonable design and space-saving

Structure of peanut grading machine

The peanut grading machine is usually composed of a feeding hopper, frame, transmission mechanism, three to five vibrating screens. The screens run at the same time. The screen is movable and can be customized according to different needs. Generally, the screen hole reaches from 6 to 10mm. Rubber bearings are used in this machine’s reciprocating motion joint because they are robust and shock-absorbing.

Groundnut grading machine working principle

Based on the differences in the diameters of nut kernels, this machine sorts nuts by mesh hole size. This peanut sieving machine accomplishes the screening and separation effect by controlling the feeding speed. Altering the angle of the vibrating screen body can change the feeding speed. After grading, the final products automatically enter different discharging ports. The groundnut grading machine is easy to use and labor-saving.
