Cashew nuts are one of the most popular and widely consumed nuts around the world. To ensure product quality and meet international standards, cashew processing requires precise sorting by size. That’s where a cashew nut sorting machine comes in. But how exactly does it work?
Step-by-Step Operation of a Cashew Nut Sorting Machine
Pre-Startup Inspection
Before turning on the machine, operators should ensure that all transmission systems, wires, and sieve layers are installed correctly. The equipment must be placed on stable, level ground.
Power On and Direction Check
Once the power is connected, make sure the drum or vibrating motor rotates in the correct direction, as indicated by the arrow on the machine. Reverse rotation is not allowed.
Feeding the Cashew Kernels
Raw, shelled cashew kernels are poured into the feed hopper. An adjustable gate controls the flow, ensuring even distribution into the sorting drum.
Grading by Size
The sorting drum contains multiple sieve sections with holes of increasing size (e.g., 18mm, 24mm, 26mm). As the drum rotates, the cashew kernels roll forward.
- Small kernels fall through the upper, smaller holes.
- Larger kernels move further and drop through the next section.
- This step-by-step process results in accurate multi-size grading.
Collection and Separation
Each size grade is collected in its own outlet chute or collection bin, ensuring no cross-contamination between grades.
Automatic Hole Cleaning System
A brush roller rotates in sync with the drum, helping clean any blocked sieve holes. This prevents clogging and ensures continuous, smooth operation.
Why Use a Cashew Nut Sorting Machine?
