The real value of your hazelnuts shows when the final output is uniform, clean, and marketable. But achieving this quality is not possible with the naked eye and manual labor alone. In fact, this method is both time‑consuming and lacks the necessary precision. The hazelnut sorting machine is one of the most important components of the hazelnut processing line—a machine that separates the kernels precisely and without damage, delivering a product ready for sale, packaging, or even export
In the following, we will review the types of sorting machines, their applications, capacities, and the advantages of the models produced by the Saifi Industrial Group
Types of Hazelnuts in Iran
Iran is one of the important hazelnut‑producing countries in the region, and the variety of Iranian hazelnuts has made the need for precise sorting greater than ever. The most common types of hazelnuts in Iran include:
● Qazvin hazelnut: the most famous and widely consumed type in the country
● Astara and Gilan hazelnuts: varying in size with relatively thin shells
● Urmia hazelnut: suitable for processing and the food industry
● Wild forest hazelnut: smaller but very flavorful
Given this diversity, the hazelnut sorting machine must be capable of precise separation based on size, weight, and kernel health
What is a hazelnut sorting machine?
A hazelnut sorting machine is a device that classifies hazelnuts kernel by kernel based on size and quality. The models from the Saifi Industrial Group are of the roller type (Roller Sorter), meaning the hazelnuts move over rotating rollers and are separated by passing through different grooves based on size. Why is the roller model the best choice for hazelnuts? The answer is found in the following advantages of roller‑type sorting machines:
● It does not damage the product
● It has high separation accuracy
● It is perfectly suitable for hazelnuts of various sizes
● It can be used for other dried fruits and sensitive products such as potato seeds, onion sets, saffron corms, dried mulberries, etc.
● Easy and controllable adjustments
These features make the Saifi roller sorting machine the only device that can sort highly sensitive products without causing damage—an advantage not seen in any similar machine on the market
Types of hazelnut sorting machines by capacity
In an industrial hazelnut processing line, various types of sorters can be found. The classification of sorters is as follows:
6‑channel hazelnut sorting machine
This model is one of the most popular options for workshops and medium‑sized production units. Suitable capacity, more economical price, high precision, and suitability for dry nut packaging are among the advantages of this machine
8‑channel hazelnut sorting machine
After the 6‑channel model, the most popular and best‑selling Saifi model is the 8‑channel sorter. Customer‑friendly features of this machine include higher speed, greater precision, suitability for larger processing lines, and the ability to sort various types of dried fruits
10‑channel hazelnut sorting machine
This machine is mostly used in large industrial units with high production volumes. It has a high capacity and is the best option for continuous and automatic lines
Our suggestion is that if you are undecided between different models, the 6‑channel and 8‑channel versions are usually the best choice, and they perform excellently for 90% of related businesses
Types of hazelnut sorting machines by size
The types of hazelnut sorting machines based on the number of rollers are as follows:
4‑roller hazelnut sorting machine
This machine has a relatively small size and we recommend using the 4‑roller hazelnut sorting machine for small workshops and when starting out
8‑roller hazelnut sorting machine
The best‑selling model in terms of roller size, with suitable speed, high precision, and excellent performance for hazelnuts and other dried fruits
20‑roller sorting machine
This model is mostly used for pistachios, with a speed of about 500 kg per hour, and due to its high capacity, the 20‑roller sorting machine is the main choice for pistachio exporters
The hazelnut sorting machine in a complete processing line
For a hazelnut processing line to produce a completely standard output, the sorting machine must be coordinated with other equipment. The relationship of the hazelnut sorter in the processing line with other machines is as follows:
● Connection with the hazelnut cracker: the output of the peanut sorting stage must enter the hopper of the industrial hazelnut cracker. So these two machines must be synchronized to increase the overall speed
● Transfer by conveyor belt: since the output of the sorting machine must enter the hazelnut cracker, the product must be fed into the cracker’s hopper using an industrial conveyor belt
● Connection to the packaging system: the uniform output of the sorting machine is ready to enter the packaging machine, which means higher speed, less manpower, and better quality

The price of the hazelnut sorting machine and the factors affecting it
The price of the hazelnut sorting machine varies according to each production line’s needs, expected capacity, and the machine’s features. To make a more informed choice, it is better to examine the main factors affecting the sorter’s price more closely:
Number of channels
The more channels a machine has, the higher its capacity, and consequently the price increases. For example, a 6‑channel machine is sufficient for workshops and medium‑sized units, while the 8‑channel model is chosen for larger lines and, due to its higher speed and power, commands a higher price. In the 10‑channel models, the cost of manufacturing and parts is also higher due to their industrial nature and high production volume
Number of rollers
The rollers are the heart of the sorting machine. The number of rollers has a direct impact on sorting precision, working speed, and output uniformity. Naturally, an 8‑roller or 20‑roller machine, which is specialized for pistachios and export, will have a higher price than smaller models because it has a more complex structure and greater capacity
Machine capacity and speed
The machine capacity means how much product it can sort per hour. For example, a machine that can sort 300 kg of hazelnut kernels per hour is stronger in terms of design, motor, bearings, and transmission system compared to smaller models. The higher the capacity, the higher the price
Quality of parts and materials
In the Saifi industrial hazelnut sorting machine, Japanese bearings, high‑quality chain drives, standard inverters, and a durable body are used. These parts directly affect the final price, but in return, they ensure the machine runs without breakdowns for years and minimize repair costs and production line downtime
Additional features and equipment
Sometimes a customer wants the machine alone, but other times, in a hazelnut sorting line, the sorter must be integrated with other equipment such as an industrial conveyor belt, a hazelnut cracker, a skin remover, and a packaging system. Therefore, the presence or absence of these items affects the final price
Customization for specific lines
Buying a hazelnut sorting machine is sometimes done with a specific purpose, such as sorting several types of dried fruits simultaneously, special settings for sensitive products like dried mulberries or potato seeds, or custom dimensions to fit into a limited space. These requirements lead to changes in design and manufacturing, affecting the price
After‑sales service and support
One of the most important parts of the price is real support. When the machine is purchased from the exclusive manufacturer, spare parts, repairs, and operator training are always available. This might increase the final price initially, but in the long run, it reduces repair costs and production line downtime
