With the advancement of food industry technology, the industry is rapidly moving toward modernization and waste reduction. Therefore, the quality of nut processing can no longer be guaranteed with traditional methods. One of the critical points in the peanut production line is the stage of separating the hard shell from the kernel—a stage that makes the difference between an ordinary product and an export-grade one.

The peanut shell separator is an intelligent machine that, using a combination of compressed air, precise vibration, and engineered design, separates pure, healthy kernels from dry shells and impurities. The evolution in the design of these machines, especially the new models from Seifi Industrial Group, demonstrates how the combination of “controlled air flow” and “multi-layer screening” has transformed the old tradition of shelling into a precise, fast, and damage-free process.

In the following guide from the Seifi website, we will examine the performance, structure, and key advantages of the peanut shell separator—from how the peanut aspirator works to a comparison of traditional and mechanized methods, technical specifications, and the factors affecting price.

Why does the peanut shell separator play a vital role in the production line?

In the peanut production line, precision and care in separating the kernel from the hard shell are particularly important. After the product enters the peanut sheller and its hard shell is cracked, crushed shells and even unbroken peanuts may still be seen in the output hopper. At this stage, the peanut shell separator comes into play. This machine, using a combination of precise air blowing/aspiration and vibrating screen surfaces, separates dry shells, fragments, and impurities from the healthy kernels.

Why does the peanut shell separator play a vital role in the production line?

This stage directly affects the final quality of the cleaned kernels, product shelf life, and the efficiency of the production line. The more precise the separation percentage and the lower the waste, the higher the final production profit. From an economic perspective, the presence of a peanut aspirator in the processing line means reduced loss of kernels among the shells and reduced labor costs for manual separation. It also increases output speed and ensures consistent quality in industrial production.

Examining the operation of the peanut shell separator

The operating system in this machine is a combination of three main parts, which are as follows:

  • Input and feeding elevator: The cracked peanuts are guided into the machine chamber via conveyor and bucket elevator.
  • Screening system (vibration and separation): Separation is carried out through precise vibration of screen plates with specific mesh sizes, so that larger pieces are separated from the kernel flow.
  • Aspiration or air blower system: The important part of the machine is the aspiration section, which, based on the weight difference and air resistance between the kernel and the shell, regulates the airflow and directs the shells toward the waste outlet.

In the new generation of Seifi Industrial Group’s machines, precise adjustments of air pressure and vibration amplitude are used so that the machine is optimized for different varieties of peanuts (such as Zarand, Astaneh, etc.). In addition, the soft, intermittent vibration prevents damage to the kernels and fully preserves the final white kernel quality.

Comparison of traditional and mechanized methods in peanut shelling

In the past, separating the shell from the peanut kernel was mostly done manually or with simple blowers. Although this method seemed low-cost, it often resulted in kernels remaining mixed with shells or getting damaged. As a result, the final quality for export or food industries was poor. Additionally, labor productivity was low and processing speed was limited.

In contrast, the mechanized method using machines equipped with aspiration and multi-stage screening has increased the separation purity percentage to over 98%. It also enables simultaneous separation of several types of impurities (thin skins, kernel fragments, dust). Sometimes, for a more uniform product, the impurity-free peanuts are fed into the peanut sorting machine for sizing and better packaging.

Comparison of traditional and mechanized methods in peanut shelling

This change is not just a technical upgrade, but an economic leap for producers. Because with modern machines such as those from Seifi Industrial Group, the quality of the final product becomes competitive with export standards.

Which workshops is the Seifi Industrial Group peanut hollow-kernel remover suitable for?

As a buyer of the peanut hollow-kernel remover, you should know that these machines are built for both small and large workshops based on their needs and production tonnage. For example, in small workshops or when starting out, you can use an aspirator with a capacity of 100 kg per hour, which also operates on single-phase electricity.

If your needs are greater than this, we recommend using the peanut shell separator with a capacity of 300 kg per hour. This machine operates on three-phase electricity. The common feature of all models is minimal operator requirement and stable performance around the clock. The stainless steel body, optimal energy consumption, and easy connectivity to other components of the peanut processing line make this machine a professional choice.

Technical specifications of the peanut shell separator

If you want to know more about the peanut kernel-shell separator, first we should say that this machine has 4 outputs. That is, clean peanut kernels without any hard shells or contaminants are delivered through one outlet, while cracked shells, hollow peanuts, and dust are delivered through separate outlets. The error rate of this machine is very low, and in the worst case, it may reach 2 or 3 percent.

The machine height is 2.90 meters, and depending on the workload, you can use a separate conveyor, bucket elevator, and automatic feeding hopper for ease of operation and for discharging peanuts at the machine’s inlet. This machine operates with a vibrating screen, which has small balls (bumpers) for high speed and large workloads to prevent peanuts from piling up or getting stuck in the mesh. Additionally, the speed and air volume are adjustable so that the machine can be used for different products. This shows that the manufacturer has considered everything to ensure the machine operates with minimal need for an operator or manual labor.

Price of the peanut shell separator and factors affecting it

The price of this machine is typically subject to three main factors, which are:

  1. Capacity and design: High-capacity machines with thicker stainless steel bodies and multi-stage aspiration systems have higher prices.
  2. Additional equipment: The presence of a conveyor and bucket elevator, dust filters, or an intelligent electrical control panel increases the initial cost but reduces operating costs.
  3. Warranty and after-sales service: In industrial models, warranty and after-sales parts supply are provided, which is one of the reasons for the popularity of Seifi products among producers.
Factors affecting the price of the peanut shell separator

In the current Iranian market, other factors such as the exchange rate, daily steel prices, and supply and demand also have a significant impact on the price of industrial products. In a situation where the exchange rate is constantly fluctuating and the steel market lacks price stability, it is Seifi Industrial Group that has managed to keep product prices fair and with maximum stability.

Frequently Asked Questions

Is the peanut shell separator sufficient on its own?

No, for complete separation, the peanut pods must first be opened in a sheller so that the kernels can enter this machine.

What is the difference between the peanut hollow-kernel remover and the shell separator?

The hollow-kernel remover only differs in name from the peanut shell separator. In hollow-kernel removal, the goal of the line is to separate lightweight peanuts, while in shell separation, the peanut kernels are separated from cracked or crushed shells.

How is the air adjustment done on the machine?

The air pressure is controlled through an adjustable blower, so it can be set according to the kernel weight and moisture content.

Is it possible to use one machine for multiple types of products?

بله، در مدل‌های جدید سیفی با تغییر توری سرند و فشار باد، می‌توانید آن را برای پسته یا فندق نیز تنظیم کنید.

Is on-site installation service provided?
