Gravity Separator – Precision Sorting by Specific Weight
The gravity separator (also known as a vibro-pneumatic table) is a critical machine for achieving maximum purity in the food and seed industry. While standard cleaners separate products by size or shape, the gravity separator sorts them by their density. This allows for the effective removal of impurities that are visually identical to the good product but differ in weight—such as shriveled, hollow, or insect-damaged grains, as well as stones and heavy contaminants.
The machine utilizes the combined action of a vibrating deck and a controlled air pressure system that blows through the screen. The product is "fluidized," causing the heavier, healthy kernels to stay in contact with the deck and move toward the high side, while the lighter particles float and drift to the lower discharge. The result is a perfectly calibrated product with the highest quality and weight uniformity.
Key Advantages:
- Removal of Internal Defects such as moldy, immature, or hollow seeds
- Fine-Tuning Controls for airflow, deck inclination, and vibration speed
- High Purity Levels reaching up to 99.9% for premium products
- Weight Uniformity essential for planting seeds and consistent downstream processing
- Heavy-Duty Construction designed to minimize foundation vibration
Application and Accuracy
This machine is indispensable for seed preparation, pulses, nuts, sunflower seeds, coffee, and spices. It serves as the final mechanical cleaning step, ensuring that only the highest quality raw materials reach the packaging line or the end customer.
