A nuts sorting machine is a specialized piece of equipment designed to accurately sort unshelled nuts into different size categories. This machine uses a rotary drum for nut sorting, effectively classifying various types of nuts with a sorting accuracy of over 95%.
The large-scale model is made entirely of carbon steel or stainless steel, offering a clean, hygienic, and durable structure. With a processing capacity of up to 2000 kg/h, it offers excellent cost performance and is widely used in the food processing and export industries.
Our nuts grading machines are widely sold across African and Asian markets, where they are favored by local nut processing businesses for their efficiency and reliability.
Applicable Raw Materials
Suitable for various round-shelled nuts, including unshelled almonds, hazelnuts, macadamia nuts, walnuts, cashew nuts, and similar nuts.
Main Functions of the Nuts Sorting Machine
Accurate Size Grading
The machine uses multiple layers of sieves with varying mesh sizes to accurately classify nuts into different grades such as W180, W210, W240, W320, and W450, meeting international export standards.
High-Efficiency Automatic Sorting
Equipped with an electric vibration system, the machine automatically performs the sorting process quickly and efficiently, greatly reducing labor costs.
Multi-Layer Sieve Design
Standard configurations include 3 to 6 sieve layers. Each layer separates kernels of a specific size, allowing for multi-grade classification. Customization is available.
Easy Operation & Maintenance
A user-friendly control panel with a clear structural layout makes the machine easy to operate and maintain, saving time and labor.
Food-Grade Hygiene Compliance
All parts in contact with the product are made of food-grade stainless steel, ensuring hygiene and meeting food safety standards required for export.
Flexible Integration
The machine can work independently or be integrated into a full processing line with shelling, drying, color sorting, and packaging equipment to improve overall efficiency.
Working Principle of Nuts Sorting Machine
The nuts sorting machine works on the principle of particle size differentiation, using vibration or rotary motion combined with multi-layer sieves to separate kernels of different sizes into specific output channels. We offer standard sieve sizes of 18mm, 24mm, and 26mm in diameter, and we can also customize the mesh size according to your specific requirements.
Working Process: Feeding → Vibration or Rotary Motion → Multi-Layer Screening → Discharge & Collection

What Are the Advantages of the Shuliy Nut Grading Machine?
Durable Carbon Steel or Stainless Steel Structure
All contact parts are made of food-grade stainless steel, ensuring hygiene, corrosion resistance, and easy cleaning. The main body can be made of either carbon steel or stainless steel to balance durability and cost.
Stable Operation with Low Noise
Equipped with a high-quality vibration motor, the machine operates smoothly and quietly, making it ideal for continuous industrial use.
High-Efficiency Grading
The machine features a multi-layer sieve structure that enables rapid and accurate sorting of cashew kernels by size. It ensures precise grading with minimal kernel breakage.
Strong Customizability
The number of grading layers, mesh size, voltage, and machine dimensions can all be customized based on the customer’s specific production needs.
Reliable After-Sales Service
After purchasing the equipment, we offer a one-year warranty. During this period, any quality issues caused by non-human factors will be repaired or replaced free of charge. Additionally, we provide technical support and operational training to ensure you can use the equipment smoothly and efficiently.
Easy Maintenance & Long Service Life
The machine is designed with a modular structure, allowing key components such as sieves and vibration units to be easily disassembled and replaced. This reduces maintenance time, lowers operating costs, and ensures long-term, stable performance even under high-capacity production conditions.
How to Operate the Nuts Sorting Machine？
Pre-Startup Inspection
- Before turning on the machine, check all transmission components and electrical circuits to ensure they are functioning properly and safely.
Power On
- Switch on the power and confirm that the drum rotates in the direction indicated by the arrow. Reverse rotation is strictly prohibited.
Feeding Process
- Continuously pour the raw nut into the feed hopper. Adjust the feed gate to ensure the nut enters the grading drum evenly.
- The grading drum consists of three sections with mesh holes arranged from small to large. Below each section is a matching collection hopper. As the drum rotates, the nut kernels tumble inside: small kernels fall through the small holes first, while larger ones continue rolling forward to the next level, achieving size-based separation.
Graded Collection
- Each outlet at the bottom of the drum corresponds to a different grade. Nuts are collected without mixing, ensuring clean and accurate classification.
Automatic Hole Cleaning
- A cleaning brush roller rotates synchronously with the grading drum. Its hard bristles are designed to automatically insert into the sieve holes to clear blockages, ensuring continuous and efficient operation without clogging.
Application Scenarios
- Nuts export processing enterprises
- Food processing and packaging plants
- Agricultural product grading centers
- Small and medium-sized nut processing workshops
Recommended Supporting Equipment
The nut grading machine is commonly used in the pre-processing stage of almond shelling lines, hazelnut shelling lines, and macadamia nut shelling lines. Its main purpose is to ensure uniform nut size before shelling, effectively reducing kernel breakage during the shelling process.
