The fully automatic hulled almond processing line is a production line that can remove almond shells. It includes three main steps: almond grading, almond shelling, and kernel shell separation. Of course, this almond shelling production line can not only remove almond shells, but also processhazelnuts, badam (almonds), macadamia nuts, peach kernels, and other nuts. It is widely used for primary processing in nut processing plants and for deep processing of almond-based food products.
This almond shelling production line has a capacity of 1–3 t/h, with a daily output of 8–24 tons. All parts in contact with the raw materials are made of stainless steel. It features a shell–kernel separation rate of over 95%, an almond breakage rate below 5%, and supports long-time continuous operation.
So far, our hulled almond processing line has been exported to Kenya, Russia, Armenia, Uzbekistan, and more than 20 other countries and regions, and is highly recognised by customers worldwide. If you need high-efficiency, large-scale almond processing, feel free to contact us for more information.

What Raw Materials can the Hulled Almond Processing Line process?
- Almonds (with shells) – the main raw material.
- Hazelnuts – suitable for shelling and kernel separation.
- Macadamia nuts – compatible with hard-shell processing.
- Peach kernels – can be shelled without damaging the kernel.
- Other similar nuts – such as walnuts, cashews, and Brazil nuts, depending on the machine’s adjustability.
Note: The line is designed to handle hard-shelled nuts while minimising kernel breakage, and all raw materials should be clean and dry for optimal performance.
Production Steps of Almond Cracking and Shelling
This almond shelling production line mainly consists of a lifting conveyor, rotary grading drum, storage hoppers, electromagnetic quantitative feeders, shelling machines, collecting conveyor, and shell–kernel separator, enabling the full-process operations of grading, automatic shelling, and shell–kernel separation. It is suitable for high-capacity, efficient almond processing.
This almond shelling production line is ideal for high-volume, continuous operations. It ensures clean shelling, high kernel integrity, and easy cleaning, making it perfect for large-scale almond processing enterprises looking to improve efficiency and reduce costs.
Production Process
- Raw Material Grading: Almonds are fed via a conveyor into a rotary sieve for grading into three or more sizes. Graded almonds enter storage hoppers and are automatically fed into three shelling machines using electromagnetic metering feeders.
- Shelling: Shelling machines have adjustable shelling gaps according to almond size, ensuring clean shelling and intact kernels. Shelled almonds and shells are transported to the kernel-shell separator.
- Kernel-Shell Separation: The separator separates shells from kernels, delivering whole almonds from one outlet and empty shells from another. The system can be custom-designed based on production capacity and almond size.
Almond Shelling Production Line Introduction
Lifting Conveyor (Raw Material Feeding)
Used to convey raw almonds from the ground or pre-processing area to the rotary grading drum, ensuring a continuous and stable supply of materials to the production line
Rotary Grading Drum
Performs size grading of the raw almonds, separating them into different specifications. This allows the shelling machines to adjust the shelling gap according to almond size, ensuring clean shell removal and high kernel integrity.
Storage Hopper
Transfers almonds from the storage hopper to the shelling machines in controlled, measured amounts, ensuring efficient shelling and preventing kernel breakage or machine blockage.
Almond Shelling Machine
The core equipment of the production line, using adjustable shelling gaps to remove shells while keeping kernels intact. Shelled almonds, together with shells, are conveyed to the shell–kernel separator for further processing.
Collecting Conveyor
Gathers the shelled almonds and shells from all shelling machines and transports them to the shell–kernel separator, allowing continuous, centralized material flow.
Shell–Kernel Separator
Separates the shells from the almonds completely. Kernels exit through one outlet while empty shells exit through another, ensuring a high shell–kernel separation rate and minimal kernel breakage for fully automated continuous production.
Grading Machine
The almond grading machine uses the vibration of a vibrating screen to separate almonds of different sizes and shapes. Almonds enter the vibrating screen from the hopper and, under the vibration of the exciter, move continuously and progressively along the screen surface. Smaller almonds pass through the screen openings, while larger almonds move forward along the screen, achieving automatic grading by size. The machine offers stable grading performance, providing uniformly sized raw materials for subsequent shelling processes, improving overall processing efficiency and almond kernel integrity.
Features of the Hulled Almond Processing Line
- High capacity for industrial production: The complete line delivers a capacity of 1–3 tons per hour, designed for continuous operation and large-scale almond processing.
- Accurate grading ensures stable shelling: Equipped with a rotary grading machine that separates almonds into four size grades, allowing precise adjustment of the shelling gap for clean shell removal.
- High kernel integrity, low breakage rate: Adjustable shelling machines combined with uniform feeding effectively reduce kernel damage, ensuring a high percentage of whole almond kernels.
- Uniform and controlled feeding: The electromagnetic quantitative feeders provide stable and even feeding, preventing overloading and ensuring smooth machine operation.
- High shell–kernel separation efficiency: The dual variable-frequency shell–kernel separatorsallow flexible adjustment to achieve high separation efficiency with minimal kernel loss.
- Food-grade stainless steel construction: All parts in contact with the almonds are made of stainless steel, ensuring hygiene, corrosion resistance, and easy cleaning.
- Stable operation and reasonable energy consumption: With a total installed power of approximately 26 kW, the production line runs stably and is suitable for long-term continuous operation.
- Wide application and customizable design: Suitable for almonds, apricot kernels, hazelnuts, macadamia nuts, and other similar nuts, the line can be custom-designed according to raw material size and required capacity.
