Working process of the almond sheller and separator processing line

The main functions of the entire production line are: automatic shelling, shell-kernel separation, kernel grading, and color sorting. The final product consists of whole almonds, macadamia nuts, and other nuts of different grades.

The complete process of the almond shelling line is as follows:

  1. Raw almond feeding and lifting: This step requires a storage silo and a lifting machine.
  2. Rotary drum grading: Grading is performed according to different screen sizes, which helps to achieve a higher shelling rate during the shelling process.
  3. Quantitative feeding to the shelling machine: Quantitative feeding ensures maximum production efficiency while preventing blockages.
  4. Shell-kernel separation: This step not only separates the kernels but also facilitates the recycling of the shells.
  5. Kernel color sorting: It effectively removes low-quality kernels, meeting the requirements of demanding customers.
  6. Final kernel grading: This grading is performed according to kernel size, which is beneficial for subsequent processing.

Application scope of the almond shelling peeling production line

This almond shelling line features an adjustable shelling gap and modular separation units, enabling it to process various hard-shelled nuts with stable performance.

Shelling parameters can be adjusted according to the hardness and size of the nut shells. After shelling, separation, and grading, the processed nut kernels can be directly used in various downstream applications:

  1. Food processing industry: Roasted nuts, flavored nuts, baking ingredients
  2. Nut deep processing: Nut slicing and chopping, nut butter production (almond butter, hazelnut butter)
  3. Various nut oil extraction: Almond oil, hazelnut oil, peach kernel oil
  4. Export and wholesale trade: Graded whole kernels can be directly used for export markets and supplied in bulk to distributors and food manufacturers.
  5. By-product utilization: The shells can be processed as biomass fuel and activated carbon raw materials.

The almond shelling line is a pre-treatment solution for nut products, supporting food processing, oil extraction, export, and nut deep processing. Its flexibility and high output make it an ideal solution for commercial nut processors and agricultural cooperatives.

Successful nut shelling peeling production line cases

Almond shelling line in Russia (1–1.5 TPH)

The client is a regional nut processing and agricultural trading company in southern Russia, specializing in the collection, primary processing, and wholesale distribution of nuts and oilseeds.

With the growing domestic demand for packaged nuts and increasing export opportunities to Eastern Europe and Central Asia, the client decided to invest in an automated almond shelling production line. We recommended a complete almond shelling line with a capacity of 1-1.5 tons per hour.

The client has a stable supply chain of raw materials, with almonds sourced from neighboring regions, including Central Asia (Uzbekistan, Tajikistan) and the Caucasus region (Armenia, Azerbaijan). However, due to variations in almond size, we provided customized sorting capabilities as an additional feature.

Macadamia nut processing line in Kenya

This client is a macadamia nut processor located in central Kenya, adjacent to major macadamia growing regions such as Murang’a and Kiambu. The company works directly with smallholder farmers and cooperatives, collecting in-shell macadamia nuts during the harvest season and processing them for export.

This project involved designing a customized macadamia nut processing line for a Kenyan client engaged in primary processing and export of macadamia nuts. We designed a complete processing solution based on the client’s factory layout, production targets, and local operating conditions.

To meet the client’s specific needs, we designed a tailored processing flow based on the characteristics of macadamia nuts and created detailed 3D layout diagrams showcasing:

  • Equipment arrangement
  • Precise height matching between machines
  • Conveying direction and material flow

The 3D design of the almond shelling line helped the client clearly understand the production line before delivery and shortened on-site installation time.

This production line has helped the client successfully consolidate its position in the Kenyan macadamia nut export industry and laid a solid foundation for future capacity expansion.

We focus on helping you solve various technical problems in nut pretreatment and deep processing, providing customized solutions for your business. If you are looking for a professional partner, Taizy is your best choice.
