HighPrecision Gravity Separator for Seeds and Beans China Factory Suppliers

We supply high-performance gravity separators with a capacity of 6–15 TPH and power of 13.2 kW. Designed to efficiently remove blighted, rotten, and moldy seeds from sesame, beans, and groundnuts, they help maintain consistent purity. Available from a China-based factory and suppliers; CE/SGS-certified units are provided.

The Gravity Separator is a high-precision industrial machine designed to sort granular materials based on the critical difference in specific gravity between the main product and its impurities. By combining controlled vibratory action with aerodynamic airflow, the equipment efficiently removes shriveled, sprouted, damaged, rotten, moldy, and non-viable seeds from a wide range of legumes, grains, and seeds—ensuring that only high-quality produce proceeds to the final stage of processing.

Built for versatility and long service life, this gravity separator is an essential solution for processing plants handling sesame, soybeans, mung beans, kidney beans, chickpeas, coffee beans, and peanuts. Through a controlled stratification process—where lighter particles rise and heavier particles settle—the system accurately separates materials of the same size but different densities, increasing the purity and commercial value of the final agricultural output.

Frequently Asked Questions

Q: What is the primary difference between a color sorter and a gravity separator?                                    

A color sorter removes impurities based on visual appearance, whereas a gravity separator removes impurities based on specific gravity (density). This makes it particularly suitable for removing insect-damaged or shriveled seeds that may appear identical in color to healthy ones.

Q: Can this machine handle different types of pulses and grains?                                    

Yes. The machine is highly flexible. With the integrated frequency converter, you can adjust the vibration frequency to suit sesame, soybeans, mung beans, chickpeas, coffee beans, and more.

Q: How does the “no-broken slope elevator” benefit the process?                                    

Conventional elevators can create mechanical impact that may crack fragile seeds. Our low-speed slope elevator transports grains gently, helping maintain the physical integrity of the product.

Q: What materials are used to support food safety?                                    

We use high-quality stainless steel for the table facets and sieves to help prevent rust and contamination, supporting compliance with food processing hygiene practices.

Q: How is separation achieved during operation?                                    

The process combines airflow (to suspend the material) and vibratory friction (to stratify it). Lighter impurities rise and flow downward, while heavier finished products move upward.

Q: Does the machine require frequent part replacements?                                    

No. Using Japanese bearings, premium beech wood frames, and brand-name motors, the machine is designed for long-term durability and minimal maintenance cycles.
