Nut grading machine

A nut grading machine is a specialized equipment used in the agricultural and food processing industries primarily for sorting and grading nuts based on their size.

This machine employs precise measurement and sorting techniques to separate nuts of different sizes, catering to various market demands and customer preferences.

Brief introduction about the nut grader machine

The machine is primarily designed for the sorting and categorization of kernels of varying sizes, including apricot pits, hazelnuts, almonds, diverse nut varieties, as well as legumes. It effectively divides them into three or more levels, facilitating their storage and subsequent sale.

The equipment consists of first, second, and third-level vibrating screens, enabling simultaneous screening and grading. The active screen panels have perforations ranging from 6 to 10 millimeters. Depending on the specific variety, screen panels can be replaced to segregate appropriately sized grades. With its well-conceived design and low crushing rate, it stands as the most favorable processing equipment for kernel-type products in current practice.

Working principle of the nut grading machine

This equipment is primarily designed for sorting kernels based on their sizes and is intended to complement a shelling machine. It capitalizes on the natural size differences among kernels, using screen perforations to carry out the classification.

Structure of the nut grading machine

This equipment is comprised of a feeding hopper, screening unit, frame, and eccentric drive mechanism. Rubber bearings are utilized at the point of reciprocating motion, known for their durability and shock absorption capabilities.

By adjusting the angle of the vibrating screen unit, the machine controls the speed of material flow, thus achieving the desired separation and screening outcomes.

Different types of nut grader machine

Our nut grading machines offer customizable grading options, typically available in two, three, and five-tier screens. This means that customers can choose the number of tiers that best suit their specific requirements. This flexibility allows our nut grading machines to meet the demands of different types and scales of production.

• Two-tier Screen Nut Grading Machine: This model uses two layers of screens for grading. It is suitable for basic grading tasks and can quickly and effectively categorize nuts based on size.
• Three-tier Screen Nut Grading Machine: This is one of our common models, utilizing three layers of screens for grading. It provides more refinement and options, making it suitable for finer categorization of nuts.
• Five-tier Screen Nut Grading Machine: This model offers the highest level of grading precision, using five layers of screens. It enables highly accurate classification of nuts and is suitable for situations where strict product quality standards are required.

Additionally, we can also customize our machines based on specific customer requirements, such as particular screen sizes or specific grading criteria. This makes our nut grading machines a flexible and customizable solution that can adapt to various production environments and needs.

3. Reduced Labor Costs: By automating the grading process, it decreases reliance on manual labor, leading to cost savings in terms of wages and associated expenses.
4. Improved Quality Control: Ensures that only nuts meeting specific quality standards are packaged for distribution, enhancing overall product quality.
5. Flexibility: Many machines allow for customizable settings to accommodate different types and varieties of nuts, providing adaptability to varying production needs.
6. Minimized Product Waste: Ensures that only high-quality nuts are processed, reducing waste and maximizing the yield of usable product.
7. Optimized Production Flow: Integrating a Nut Grading Machine into the production line streamlines operations and reduces bottlenecks, leading to improved overall production efficiency.

Recommendations for using nut grading machine

1. Before utilizing the equipment, it is essential to conduct a thorough inspection to ensure that major components have not incurred any damage during transit, and that all connecting parts are securely fastened. Additionally, verify the integrity and safety of all electrical switches and circuits.
2. Initiate the machine’s operation initially, confirming that it is functioning smoothly, before commencing actual work.
3. Introduce the kernels into the feeding hopper and regulate the discharge gate to maintain a uniform material flow, aligning it with the screening and grading pace. Avoid excessive loading to prevent any adverse impact on the separation efficiency.
4. In instances where multiple shelling machines are employed in tandem, the inclusion of a lifting conveyor for material introduction can significantly reduce labor intensity and optimize manpower allocation.
