CLOSED LIGHT GRAIN

It is a machine used to separate light grained foreign materials (weak, damaged, moisture-lost and therefore discolored products) from previously sorted products. After this sorting process, the products are passed through the light grain separation machine to increase their quality. It exhibits a very effective performance especially in products such as sesame and cumin. It is also used in agricultural products such as barley, wheat and lentils.

Closed Light Grain: Precision Separation with Enclosed System Comfort

Advanced Seed and Grain Processing for Maximum Quality

In seed processing lines, one of the most effective ways to enhance product quality and reduce waste is the physical separation of healthy, filled kernels from light, empty, broken, or damaged ones. This separation relies on airflow and density difference principles.

The Closed Light Grain is a modern light grain separator that performs this task with priority on environmental hygiene and operator safety. Its enclosed body design minimizes dust spread, keeps the workspace clean, and protects operator health.

Advantages of Enclosed System Design

  • Dust Control: Operates without releasing dust into the environment

  • Hygiene Compliance: Meets GMP, HACCP, and ISO 22000 standards

  • Energy Efficiency: Optimized airflow direction ensures consistent performance

  • Operator Safety: Eliminates dust inhalation risk and ensures a clean workspace

Working Principle: Density-Based Separation with Controlled Airflow

  1. Feeding: Product enters the inlet hopper

  2. Air Curtain: Vertical airflow lifts light grains upward

  3. Density Separation: Heavy and filled kernels settle down, while lighter fractions are discharged from the top

  4. Discharge: Valuable filled kernels and light fractions are collected separately

This method improves kernel fill ratio, uniformity, and reduces load on downstream machines.

Technical and Design Features

  • Separation Mechanism: Vertical air curtain + density-based separation

  • Body: Enclosed, dust-proof design

  • Capacity: 2–10 tons/hour (depending on product type)

  • Power Consumption: 1.1 – 2.2 kW

Frequently Asked Questions (FAQ)

1. What is the difference from an open-type separator?
Closed system ensures dust control and higher hygiene standards.

2. Which products benefit most?
Cereals, legumes, and hybrid seeds where volume is similar but density differs.

3. How is airflow adjusted?
Via manual control lever or PLC system for product-specific settings.

4. Can it be connected to automation?
Yes, it supports PLC/SCADA integration for automatic adjustments.

5. Is cleaning easy?
Yes, with easily accessible interior panels and wide-opening covers.

Conclusion
The Closed Light Grain combines precision separation with the advantages of a sealed, dust-free system. It delivers higher product quality, cleaner working conditions, energy efficiency, and easy usability—a reliable solution for seed processing, legume plants, and certified seed production.
