The hazelnut opening line is an automated processing solution that integrates soaking, opening, drying, and packaging. It is primarily used to precisely create a slit in the outer shell of whole hazelnuts and complete the subsequent drying and packaging processes.

Through a multi-channel continuous operation design, this production line can achieve a stable output of 250–600 kg/h, suitable for hazelnut processing projects of various scales. It effectively improves overall processing efficiency and product quality while ensuring consistent shelling results.

Advantages of hazelnut processing line

  • From soaking and opening to drying and packaging, the entire production line is seamlessly integrated, improving overall operational efficiency.
  • Our hazelnut opening line is available in multiple configurations. Customers can flexibly choose between 10, 15, or 20 channels depending on their target production volume.
  • The combination of steam-assisted technology and a specialised extrusion disc structure ensures consistent opening of the hazelnuts. This facilitates subsequent drying and packaging processes.
  • The lifting, sorting, opening, and discharge processes operate continuously, reducing manual labour and making it suitable for long-term stable production.

What equipment is used for hazelnut opening line?

Our hazelnut cracking and processing line equipment mainly includes:

  1. Hazelnut soaking equipment
  2. Hazelnut opening machine
  3. Hazelnut drying machine
  4. Hazelnut packaging machine

The equipment in this hazelnut opening line can be customized and selected according to specific needs.

Hazelnut soaking machine

The soaking tank is used to soak the hazelnuts in warm water at approximately 50°C for about 30 minutes. This softens the hazelnut shells, improving the success rate of subsequent opening and reducing breakage.

Hazelnut opening machine

The main function of the hazelnut opening machine is to create a uniform slit on the surface of whole hazelnuts. This equipment is equipped with a steam generator, which reduces the rate of hazelnut breakage.

Our hazelnut opening equipment is available with 10, 15, and 20 channels, allowing customers to choose the one that best meets their needs.

Hazelnut drying machine

After the hazelnuts are cracked open, they need to be dried in a drying chamber. The drying process effectively reduces the moisture content of the hazelnuts, improving their taste and extending their shelf life.

Hazelnut packaging machine

After drying, hazelnuts can be packaged using a vacuum packaging machine. This packaging method effectively prevents moisture absorption and oxidation, extending shelf life and improving product quality, making them suitable for retail and export markets.

In addition to vacuum packaging machines, we also offer other types of hazelnut packaging machines, such as the granular pouch packaging machine.

Working principle of hazelnut processing line

  1. Soaking: Soak the hazelnuts in warm water at approximately 50℃ for about 30 minutes.
  2. Feeding: The soaked hazelnuts are poured into a conveyor, which transports them to a hopper. The hopper has a spiral feeding structure that evenly distributes the hazelnuts to different channels.
  3. Opening: The hazelnuts enter the hazelnut opener and are squeezed by two pressing discs, achieving precise opening.
  4. Discharge: The opened hazelnuts automatically fall onto a conveyor belt below, entering the subsequent drying or packaging process.

How much does hazelnut processing line cost?

The price of the hazelnut opening line is not fixed and is typically influenced by the following factors:

  • Production capacity configuration: The number of sets and channels (10/15/20 channels) significantly impacts equipment costs.
  • Selection of supporting equipment: Whether or not to include soaking tanks, drying rooms, and vacuum packaging machines will directly affect the overall quotation.
  • Customisation requirements: Such as voltage standards, degree of automation, or special structural requirements.
  • Production line scale: The price difference is significant between a single piece of equipment and a complete production line.

FAQ of hazelnut opening line

What is the capacity of the hazelnut opening line?

250-600kg/h.

Why do hazelnuts need to be soaked before being shelled?

Soaking the hazelnuts softens their shells, which helps increase the success rate of opening them and reduces the rate of breakage.

Are the soaking temperature and time fixed?

The general recommendation is to soak them in warm water at approximately 50℃ for about 30 minutes. This can be adjusted depending on the type of hazelnuts.

Is it possible to configure the production line with only a portion of the equipment?

Yes. The production line supports modular configuration, allowing customers to select equipment based on their specific needs.

Is it possible to customize the product according to customer requirements?

Yes. Production capacity, voltage standards, and equipment layout can all be adjusted according to project requirements.
