Call To Action

The nut shell kernel separator is an important piece of equipment in the nut processing industry, mainly used to efficiently separate cracked nut shells from kernels. This machine is widely applied in processing lines for walnuts, almonds, hazelnuts, cashews, and other nuts, and serves as a key supporting unit after nut cracking equipment.

Nut Shell Separator Machine Overview

In the nut processing industry, after being processed by a nut shelling machine, the materials are usually in a mixed state of shells and kernels. To improve final product quality and production efficiency, a shell and kernel separation machine is required for secondary sorting.

This equipment uses differences in material specific gravity and air separation principles to automatically separate shells from kernels. It greatly reduces manual picking and significantly improves the level of production automation.

Working principle of almond separating machine

The almond separating machine is driven by a double vibration motor. When the two vibration motors synchronize and reversely rotate, the exciting forces generated by the eccentric blocks cancel each other in a direction parallel to the motor axis and stack in a direction perpendicular to the motor axis. A combined force, so the trajectory of the walnut screening machine is a straight line. The two motor shafts have an inclination angle with respect to the screen surface. Under the force of the excitation force and the material self-gravity, the material throws up and jump forward in a linear motion on the screen surface, thereby achieving the purpose of screening and classifying the materials.

Typical Nut Processing Line Workflow

In a complete nut processing line, each piece of equipment works together to ensure efficient and stable automated production:

1. Nut Grading Machine

First, raw nuts are fed into a nut grading machine for size classification. Based on diameter or weight, the nuts are typically divided into 3–4 grades. This grading process ensures more uniform cracking in the next step and helps reduce incomplete shelling or kernel damage caused by size variation.

2. Nut Cracking Machine

Next, the graded nuts are sent to a nut cracking machine (shelling machine). By adjusting the cracking gap, the shells are effectively broken while keeping the kernels as intact as possible. At this stage, the output material is a mixture of shells and kernels.

3. Nut Shell Kernel Separator Machine

Then, the mixed material enters this nut shell kernel separator machine. Using a combination of vibration and airflow separation, the machine efficiently separates lighter shells from heavier kernels, significantly reducing manual labor and improving separation efficiency and cleanliness.

4. Nut kernel Grading Machine

After separation, the kernels may still vary in size. Therefore, they are further processed by a kernel grading machine, which sorts the kernels into different grades based on size or quality (such as whole kernels, half kernels, and broken pieces), meeting different market requirements.
