Step-by-Step Destoning Process

🔹 Step 1 – Product Feeding: Seeds are loaded into the pre-storage hopper and fed uniformly onto the deck via magnetic feeder.
🔹 Step 2 – Air Stratification: Built-in fans create pressurized airflow that lifts lighter seed particles while allowing stones and heavy materials to sink.
🔹 Step 3 – Vibratory Separation: The eccentric system moves heavy particles in one direction and clean seeds in another for accurate sorting.
🔹 Step 4 – Product Discharge: Clean seeds are discharged into the output hopper, while dense impurities are directed to a separate outlet.

Frequently Asked Questions

How does a grain destoner work?


A grain destoner uses controlled airflow and vibration to separate heavier impurities like stones and glass from lighter grains and seeds. While the air lifts the clean material, dense particles remain on the deck and are discharged separately.



What is the function of a destoner?


The primary function of a destoner is to remove stones, metal pieces, sand, and other heavy foreign materials from grains and seeds to ensure product purity, prevent machinery damage, and enhance processing efficiency.



What crops can be cleaned with the Mmctech Destoner Separator?


The Mmctech Destoner Separator effectively removes stones and heavy impurities from a wide range of products including wheat, sunflower, sesame, lentils, beans, chickpeas, soybeans, coffee beans, and garden seeds like tomato and parsley.



Does the Mmctech Destoner offer adjustable settings for different grains?


Yes, the Mmctech Destoner features customizable air pressure, vibration speed, and deck inclination settings to suit various seed and grain types. This flexibility ensures precise and efficient stone removal for each crop.
