What Equipment is in a Complete Hazelnut Opening Line? Soaking to Packaging Guide?

Hazelnuts are a high-value crop, widely used in chocolates, confectionery, and as healthy snacks. However, the hazelnut shell is notoriously hard. Processing them manually is slow and often results in broken kernels.

To turn raw hazelnuts into a profitable commodity, you need an industrial solution: a complete Hazelnut Opening Line.

But what exactly goes into this production line? It’s not just a cracker. To ensure a high percentage of whole kernels and a long shelf life, the process involves four critical stages. In this guide, we break down the essential equipment: The Soaking Machine, Opening (Shelling) Machine, Drying Machine, and Packaging Machine.

Hazelnut Soaking Machine

You might wonder, why soak hazelnuts before cracking?

The function: the hazelnut soaking machine is the first step. It immerses the dry, hard hazelnuts in water (sometimes with specific additives depending on the process) for a set period.

The science: soaking softens the fibrous shell structure. This makes the shell less brittle and more pliable. When the nut hits the cracking machine later, the shell splits open cleanly rather than shattering into tiny pieces. This pre-treatment significantly increases the whole kernel rate and reduces damage to the nut meat.

Hazelnut Shelling Machine

This is the heart of the hazelnut opening line. Once the shells are softened, they move to the cracking stage.

The function: the hazelnut shelling machine applies precise mechanical pressure to fracture the shell without crushing the kernel inside.

Key features:

  • Adjustable gap: different batches of hazelnuts have different sizes. Our machines allow you to adjust the cracking gap to minimize broken kernels.
  • High efficiency: unlike manual cracking, this machine can process hundreds of kilograms per hour, separating the hard shell from the delicious kernel efficiently.

Hazelnut Drying Machine

After soaking and cracking, the kernels (and shells, if not fully separated) contain excess moisture. They cannot be packaged immediately, or they will mold.

The function: the hazelnut drying machine removes the moisture absorbed during the soaking process and the natural moisture of the fresh nut.

Dual benefit:

  • Shelf life: it brings the moisture content down to a safe level for long-term storage.
  • Flavor enhancement: controlled drying/roasting brings out the rich, nutty aroma of the hazelnut, making it more appealing to consumers.

Hazelnut Packaging Machine

The final step is preparing the product for the shelf.

The function: the hazelnut packaging machine weighs and seals the processed kernels into bags.

Vacuum packaging: for high-end hazelnuts, we recommend a vacuum packing machine. By removing the air, you prevent oxidation (which makes nuts go rancid) and keep the kernels crunchy and fresh for months.

Versatility: whether you need small 100g retail bags or large 5kg bulk sacks, the machine can be adjusted to fit your market needs.

Why Choose Our Hazelnut Line?

Processing hazelnuts requires a delicate balance between force and precision. Here are the advantages of Taizy hazelnut open line:
