GRADING SIEVE

It is a seed processing tool that classifies seeds and pulses according to length and size differences, ensuring that the end product meets market standards. It has a range of steel sieves and spare parts availability, a wooden case for durability and offers high quality output with low maintenance. The sieves are easy to replace and provide high yield rates, making this machine a convenient and efficient tool for seed processing plants.

Tanis Grading Sieve: Precision Sizing and Quality Separation

The Importance of Size Consistency in Product Quality

In the grain and seed processing industry, not only purity but also consistency of grain size is a critical factor that determines quality. Variations in size affect multiple processes—from germination rates to packaging accuracy. The Tanis Grading Sieve, with its multi-layer sieve structure and vibratory conveying system, separates products precisely according to size, standardizing quality and increasing product value.


Working Principle

The system begins by feeding products onto the top layer of sieves. As the vibratory conveying motion moves the product across the sieve surface, smaller grains fall through to the lower layers, while larger grains remain on the upper layers. With multiple sieve layers of different mesh sizes, products can be separated into 2, 3, or 4 fractions.

This method is effective both for pre-classification stages and for final quality control before packaging.


Application Areas

The Tanis Grading Sieve can be used across a wide range of products:

  • Wheat, barley, corn, rye

  • Chickpeas, lentils, beans

  • Sunflower, canola, sesame, flaxseed

  • Hybrid seeds

  • Granulated feed, pellets, and nuts

It can be positioned at the beginning of a plant for pre-separation or at the packaging line for final sizing.


Key Features

  • Multi-Size Separation: Up to 2–5 different fractions in a single pass

  • Precision Grading: Special sieve surfaces for millimetric accuracy

  • Easy Cleaning: Modular structure with tool-free sieve change

  • Energy Efficiency: Low-power, high-efficiency motor system

  • Quiet Operation: Balanced weight distribution and isolated chassis

  • Automation Compatibility: Full integration with PLC/SCADA systems


Process Advantages

The Grading Sieve not only cleans products but also standardizes size for consistent quality. This is particularly important in seed certification, special product grouping, and packaging operations. For hybrid seeds, separating by size differences enhances germination success and agricultural productivity.

Grading also helps clearly define product groups for sale, reduces waste rates, and simplifies inventory management.


Maintenance & Cleaning Ease

The modular sieve carriers allow quick removal and replacement of sieves. Brush or ball cleaning systems keep sieve surfaces continuously clean, ensuring consistent performance. The opening cover design speeds up cleaning and maintenance tasks.


Integration & Control

Fully compatible with PLC and SCADA systems, the sieve supports automatic product flow management, error reporting, and start/stop control. This ensures continuous efficiency and monitoring across the production line.
