How the Mmctech Spiral Seed Separator Works

The Spiral Seed Separator utilizes gravity and centrifugal force to effectively separate seeds based on their shape and rolling ability.

Step-by-Step Seed Sorting Process

🔹 Step 1 – Seed Input at the Top: Seeds enter the spiral blades at the highest point of the system.
🔹 Step 2 – Round Seed Acceleration: Round seeds gain speed during descent and are transported to an outer spiral blade.
🔹 Step 3 – Centrifugal Force Separation: The outer spiral blade carries round seeds to a secondary trough.
🔹 Step 4 – Slower Descending Seeds: Non-round seeds descend along the inner spiral blade, where they are collected separately.
🔹 Step 5 – Adjustable Sorting Capacity: The number of spiral blades can be increased to handle higher processing volumes.


Applications of the Mmctech Spiral Seed Separator

The Mmctech Spiral Seed Separator is designed for various agricultural and industrial seed sorting applications, including:

🔹 Grain & Oilseed Sorting – Separates wheat, barley, sunflower seeds, and canola based on shape.
🔹 Vegetable & Herb Seed Processing – Ideal for sesame seeds, clover, and spice seeds.
🔹 Legume & Pulse Sorting – Ensures high-purity classification of chickpeas, lentils, and soybeans.
🔹 Seed Coating & Treatment Plants – Prepares seeds for further processing and treatment applications.

Frequently Asked Questions

What is the purpose of gravity separation in seed processing?


Gravity separation in seed processing helps separate seeds based on their weight and shape. This technique improves seed purity by removing lighter, damaged, or irregular seeds that may negatively affect germination and overall crop performance.



What is shape-based seed sorting?


Shape-based seed sorting is a method that separates seeds according to their physical form—such as round, flat, or irregular shapes. This process is particularly useful for distinguishing between desirable and unwanted seed types during cleaning or grading.



How does the Mmctech Spiral Seed Separator work?


The Mmctech Spiral Seed Separator uses centrifugal force and a multi-level spiral blade system to sort seeds. Round seeds roll faster and are directed to the outer edge, while flat or irregular seeds descend more slowly and are collected separately. This mechanical sorting requires no air or vibration.



What types of seeds can be sorted using the Spiral Seed Separator?


This machine is ideal for sorting wheat, barley, chickpeas, lentils, sesame, sunflower seeds, soybeans, and more. It is especially effective in separating round seeds from flat or broken ones, making it perfect for grain, oilseed, pulse, and vegetable seed processing lines.
